Outcomes, risk of other malignancies, and need for formal mapping procedures in patients with perianal Bowen's disease.

PURPOSE: Local excision is standard treatment for Bowen's disease, but controversy exists over the incidence of synchronous and metachronous cancers as well as the role of a preexcision mapping procedure. METHODS: The medical records of 25 patients treated for perianal Bowen's disease between 1978 and 2001 were retrospectively reviewed. RESULTS: There were 11 men and 14 women with a mean age at diagnosis of 47.9 +/- 14.9 years. The majority of patients (72 percent) had symptom-driven biopsies. Presentation included pruritus (56 percent), mass (28 percent), bleeding (24 percent), and anal pain (4 percent). The average duration of symptoms before diagnosis was 1.3 +/- 0.5 years. Two patients had microscopic disease discovered incidentally after hemorrhoidectomy and underwent no further treatment. Twenty-three patients underwent wide local excision, of which 19 (83 percent) had a formal mapping procedure. On final pathology, 23 patients (92 percent) had clear margins. There were three recurrences (mean time to recur 2.0 +/- 1.0 years), including the two patients who had positive margins after wide excision (1 after mapping) and one patient who had clear margins after mapping. Five patients (20 percent) had other carcinomas (1 sigmoid, 4 vulvar). At follow-up, 24 patients were alive with no evidence of Bowen's disease and 1 patient was dead secondary to sigmoid cancer with no evidence of Bowen's disease. CONCLUSIONS: Wide excision of perianal Bowen's disease results in excellent local control, although this is highly dependent on clear pathologic margins. A formal mapping procedure does not preclude recurrence. Initial screening and follow-up regimens are not uniform because of the wide range of treatment options available.

Treatment of Bowen's disease with a specially designed radioactive skin patch.

Bowen's disease can be treated by various methods, including surgical excision, cryosurgery, laser ablation, curettage, Mohs' microsurgery and ionizing radiation. Radiotherapy has been a useful therapeutic modality in the treatment of Bowen's disease and other skin cancers in areas which are difficult to excise, especially the central areas of the face, including eyelids, nose and lips. To overcome some of the disadvantages of external radiotherapy, a specially designed skin patch coated with high-energy beta-emitter holmium-166 was made for topical application at our institute. Twenty-nine sites of Bowen's disease in eight patients, confirmed by skin biopsy, were treated with 166Ho patches. The patches were applied to the surface of skin cancers for 30-60 min for a total radiation dose of 35 Gy (3500 rads). One to two weeks after application of the 166Ho patch, desquamation, erythema or erosion developed in treated sites, but these acute radiation reactions healed gradually with epithelial regeneration, and they showed good functional and cosmetic results without any complications. Follow-up biopsies were performed 1-5 months after 166Ho patch therapy, and they did not show any signs of Bowen's disease. One to two years after treatment with 166Ho skin patches, there were no recurrences of Bowen's diseases and no late complications. The 166Ho patch is an effective and convenient alternative method for the treatment of Bowen's disease that yields good cosmetic and functional results.

Bowen's diseases and basal cell carcinomas in a patient.

Bowen's disease is a well-known precancerous lesion, in which invasive squamous carcinoma may develop. However, it is rare that Bowen's disease, basal cell carcinoma, and internal malignancy develop in a single patient. We report a case of a 54-year-old male patient with Bowen's disease, basal cell carcinoma of the skin, and squamous cell carcinoma of the lung. Multiple scaly erythematous patches had developed several years earlier and were diagnosed as Bowen's disease by skin biopsy. The number of lesions increased and, five months ago, a right lower lobectomy was done for squamous cell carcinoma which was detected on a chest X-ray. Skin biopsies of two different sites revealed Bowen's disease and basal cell carcinoma. The arsenic level was increased in his hair specimen. Cryotherapy was applied.

Evaluation of acetowhitening in Bowen's disease.

BACKGROUND: From a clinical standpoint, the lesions of Bowen's disease (squamous cell carcinoma in situ) are generally sharply demarcated. Following excision, however, contiguous extension and/or small foci of Bowen's disease are occasionally found, located outside the clinically apparent margins. Acetowhitening has been suggested as a means of delineating the extent of involvement and identifying subclinical lesions of condyloma acuminata. More recently, acetowhitening has offn similarly reported to be of potential value in the presurgical evaluation of Bowen's disease. OBJECTIVE: The purpose of this investigation was to further evaluate the use and reliability of acetowhitening both to delineate margins of Bowen's disease and to identify subclinical foci of involvement. METHODS: Eight patients with histologically confirmed Bowen's disease were studied. Six percent acetic acid was applied to the lesions and the surrounding skin. Histologic examination of acetowhite lesions and adjacent acetowhite skin as well as adjacent, nonwhitened normal appearing skin was performed. RESULTS: Our results were inconsistent, and included both false positives and false negatives. CONCLUSIONS: Acetowhitening is unreliable in identification of Bowen's disease. Clinically normal, acetowhite-negative skin adjacent to a lesion of Bowen's disease may be involved.

Detection of human papillomavirus in nongenital Bowen's disease by in situ DNA hybridization.

Genital Bowen's disease has been strongly linked in recent studies to human papillomavirus (HPV). Nongenital Bowen's disease has been less well investigated, although isolated reports, all of which involved detection of HPV after extraction of DNA from fresh-frozen tissue, have been made. We investigated 25 cases of nongenital Bowen's disease in 5 black and 20 white patients for the presence of HPV types 1, 6, 11, 16, and 18 using paraffin-embedded tissues. Human papillomavirus was present in six specimens from 3 of the 5 black patients (one previously reported to be positive on Southern blot) and 3 of the 20 white patients; HPV 16 was detected in all 6 cases on low-stringency testing, but only 4 remained positive on high-stringency testing. This suggests an HPV closely related to but not entirely homologous with HPV 16 in the 2 remaining cases. Five of the 6 positive specimens were lesions from the hands and feet and 1 was from the volar aspect of the arm. Clinical factors associated with the presence of HPV included black race, location on the palmar surface and the feet, young age, and verrucous or hyperkeratotic clinical appearance. Of the 6 positive cases, all 5 of the patients available for examination also had evidence of HPV-associated genital lesions. No specific histopathologic features were found to be indicative of the presence or absence of HPV.

Bowen's disease of the umbilicus simulating psoriasis vulgaris.

Bowen's disease and other primary cutaneous malignancies are uncommon in patients with psoriasis. Primary malignancies of the umbilicus are also unusual. Plaques of psoriasis and Bowen's disease may appear morphologically similar, requiring examination of a biopsy specimen for definitive diagnosis. We report on a patient with psoriasis who experienced Bowen's disease of the umbilicus that was initially believed to be psoriasis.

Treatment of Bowen's disease and erythroplasia of Queyrat.

Bowen's disease of the skin may have differing clinical presentations depending on the skin surface on which it presents, but has the same histologic features of squamous cell carcinoma in situ wherever it occurs. The etiologic factors include ultraviolet light and human papillomavirus infection. The choice of therapy requires a consideration for retention of form, function and cosmosis while offering a high cure rate. The immunodualtory agent imiquimod has been shown to be an effective treatment on a variety of skin surfaces.

The presence of mucosal human papillomavirus in Bowen's disease of the hands.

BACKGROUND: Bowen's disease (BD) of the genital skin region is generally associated with human papillomavirus (HPV) infection. Various molecular analyses have identified mainly HPV-16 in the lesions. However, the HPV genotypes associated with BD of the hands have not yet been characterized. METHODS: The skin specimens of 12 patients with BD of the hands were investigated clinicopathologically and immunohistochemically, and the total DNAs extracted from the skin were analyzed for the presence of HPV DNA using Southern blot hybridization and polymerase chain reaction (PCR) in combination with restriction fragment length polymorphisms (RFLP) and direct sequencing analysis of the amplified products. In addition, the histologic localization of HPV DNA was examined by in situ hybridization in paraffin embedded sections of HPV positive patients. RESULTS: In 8 of 12 BD lesions (66.7%), HPV types (HPV-16, -31, -54, -58, -61, -62, and -73) were detected by Southern blot hybridization and/or PCR with RFLP and direct sequencing analysis. In 6 of 7 HPV positive lesions examined (85.7%), the viral genomes were identified by in situ hybridization in the nuclei of keratinocytes in the upper stratum malpighii and/or stratum corneum. CONCLUSIONS: These results demonstrate that BD of the hands is frequently associated with HPV infection. The seven HPV genotypes are known as mucosal (genital) HPVs and to the authors' knowledge, this is the first time HPV-31, -54, -58, -61, -62, and -73 have been identified in BD lesions. These findings strongly suggest that HPVs related to mucosal lesions play an important role in the development of BD of the hands.

Topical 5-fluorouracil in the management of extensive anal Bowen's disease: a preferred approach.

PURPOSE: An alternative approach to anal Bowen's disease was investigated. The use of topical 5 percent 5-fluorouracil for large lesions and surgical excision of small lesions were evaluated. METHODS: A prospective study was undertaken for anal Bowen's disease in 11 patients over a six-year period. Before therapy all patients underwent anal mapping biopsy and colonoscopy. For one-half circumferential disease or greater, patients underwent topical 5 percent 5-fluorouacil therapy for 16 weeks. For smaller involvement, wide surgical excision was performed. All patients underwent anal mapping biopsy one year after completion of therapy. RESULTS: Of 11 patients, 8 (5 male) received 16 weeks of topical 5 percent 5-fluorouacil therapy. Three patients (3 female) underwent surgical excision for localized disease. All but one patient, who was HIV positive, were free of Bowen's disease one year after completion of therapy. One patient underwent total excision of a residual microinvasive squamous carcinoma after circumferential Bowen's disease had resolved. One patient received eight additional weeks of topical 5-fluorouacil therapy for incomplete resolution. All patients were followed yearly, with a mean follow-up of 39 months and a range of 12 to 74 months. There have been no recurrences. There were no long-term side effects or morbidity from topical 5-fluorouacil or local excision. All colonoscopies were normal. CONCLUSION: Topical 5 percent 5-fluorouacil therapy is a safe and effective method to treat anal Bowen's disease. Wide local excision is appropriate for smaller, isolated areas of disease. Anal Bowen's disease was not associated with colonic or other neoplasms.

[Oncogenic mucosal human papillomaviruses in Bowen's disease of the hands].

INTRODUCTION: The association between genital Bowen Disease (BD) and human papillomavirus (HPV) especially HPV-16 infection is well known, but it is more rarely related to extragenital BD. The aim of this study was to detect the presence of oncogenic HPV infection in the BD of the hands considering the histology and the presence of oncogenic HPV detected by in situ hybridization (ISH) and polymerase chain reaction (PCR). MATERIAL AND METHODS: Eleven formalin-fixed and paraffin-embedded samples of BD of the hands were selected. We looked for koilocytosis using standard histological procedure. ISH was performed using genomic HPV DNA probes types 16, 18 and 33 labeled with digoxigenin. Next, with a new amplification system using biotinyled tyramide (Kit Dako Gen Point K620) was used to detect hybrids. Otherwise, Baay's HPV type specific primers (type 16, 18, 31 et 33) were chosen for PCR. RESULTS: Koilocytosis were observed in all cutaneous samples. HPV 16 was detected in 9/11 cases (82 p. 100): 2/10 with ISH and 9/11 with PCR. DISCUSSION: We report here the largest series of BD of the hands, associated with HPV type 16 infection. This high rate (82 p. 100) compared to the other series is linked to the high sensitivity of PCR and is increased by the choice of Baay's oligonucleotide primers. Besides, the low HPV rate (2/10) by ISH, is similar to those obtained in the other series. Although ISH is less sensitive than PCR, the morphological study was useful to argue the pathogenicity of HPV. Finally, the high prevalence of genital oncogenic HPV on the hands, plaid in the scratching hypothesis resulting in autoinoculation from HPV lesions in the genital region.

Patterns of basal cell keratin 14 expression in Bowen's disease: a possible marker for tumour progression.

BACKGROUND: Bowen's disease is a well-established in situ malignancy of the epidermis. The keratin expression in Bowen's disease has been studied in many reports. However, the patterns of keratin (K) 14 expression in each case have not been closely examined. OBJECTIVES: To investigate if the pattern of expression of K14 has a relationship with tumour progression, we analysed the expression patterns of K14 in relation to the nature of tumour cells, comparing tumour cells in direct contact with the dermis, tumour cells separated from the dermis, and tumour cells invading into the dermis. METHODS: Twenty-seven tissue sections from 22 patients were stained with anti-K14 antibody, as well as with antilaminin and periodic acid-Schiff (PAS) staining to evaluate the conditions of the basement membrane. Staining patterns of K10 and integrin beta1, and their relationships with proliferating cell nuclear antigen (PCNA) and Ki-67 staining patterns, were also examined. RESULTS: Tumour cells with no, or with obscured, basement membranes always showed positive staining for K14, while those with continuous (intact) basement membranes usually did not. Of 10 sections showing dermal involvement of Bowen's disease, five were K14 positive and five were K14 negative. All of these K14-positive sections with dermal involvement showed negative or obscured laminin and PAS staining. Most of the sections having K14-negative tumour cells with dermal involvement showed K14-positive lining cells with continuous staining with laminin and PAS-positive basement membranes. K10 was reciprocally expressed with K14 in most of the sections. Integrin beta1 was expressed in the basal layers of non-tumour epidermal cells, but not in tumour cells. Ki-67 and PCNA were expressed at high frequencies in tumour cells, clearly demarcating tumour cells from non-tumour cells. CONCLUSIONS: Tumour cells separated from the dermis by lining cells were K14 negative with PAS- and laminin-positive basement membranes around them; tumour cells without lining cells were K14 positive with or without continuous basement membranes. K14 expression may be a marker of tumour progression in Bowen's disease.

Aneuploidy in Bowen's disease.

Distinct aneuploid clones of keratinocytes were detected in six cases of cutaneous Bowen's disease. As Bowen's disease is an accepted precursor of malignancy, aneuploidy may prove to be a useful indicator of the risk of invasive change in dermatoses questionably pre-malignant.

Perianal Bowen's disease: a clinicopathologic study of 47 patients.

PURPOSE: Perianal Bowen's disease is an uncommon squamous-cell carcinoma in situ usually treated by surgical excision. There are controversies concerning surgical margin extent, because the disease is likely to recur in nonexcised skin areas of the anal and perianal skin. The aims of this study were 1) to determine the recurrence rate after different surgical treatments and 2) to determine if molecular markers might have a prognostic role in perianal Bowen's disease. METHOD: Retrospective chart review from 1972 to 1993 of 47 patients with perianal Bowen's disease was undertaken. Follow-up was obtained by office visits and/or phone questionnaire. Immunohistochemical analysis for p53 protein and Ki-67 nuclear antigen was conducted on fixed tissue specimens. RESULTS: Twenty-six patients were treated by wide local excision with microscopic clearance of resection margins, 15 by local excision with only macroscopic clearance of resection margins, 5 by CO2 laser vaporization, and 1 by abdominoperineal resection because of fecal incontinence. Median follow-up for the entire population was 104 (range, 16-273) months. The incidence of local recurrence was 23.1 percent (6/26) after wide local excision, 53.3 percent (8/15) after local excision, and 80 percent (4/5) after CO2-laser vaporization. Recurrence rate estimated by Kaplan-Meier analysis is statistically different (P = 0.002) between radically treated patients (wide local excision/abdominoperineal resection; n = 27) and patients undergoing conservative treatment (local excision/laser vaporization; n = 20). Among patients with recurrence, the median time until recurrence was 38.5 (range, 3-89) months and 41.5 (range, 4-111) months after conservative and radical treatment, respectively. Nine of 20 (45 percent) patients in the conservative group and none of the 27 patients in the radical group had multiple episodes of recurrence (P < 0.001). In addition, 3 of 20 and 0 of 27 patients in the respective groups developed an invasive cancer (P = 0.034). Positive staining for p53 protein was observed in 12 (33.3 percent) of the 36 tissue specimens available for immunohistochemical analysis. Recurrence occurred in 9 of 24 (37.5 percent) patients negative for p53 and in 6 of 12 (50 percent) patients with positive p53 expression (P = not significant). Ki-67 antigen-graded expression from 1+ to 4+ did not reveal any correlation with incidence of recurrence. Recurrence rate did not differ by p53 and Ki-67 results, either in the overall group of 36 patients or stratified by surgical treatment groups. CONCLUSION: Wide local excision for perianal Bowen's disease leads to a significantly lower recurrence rate than local excision or laser therapy. Follow-up longer than five years is recommended because of the risk of late recurrence. p53 protein and Ki-67 antigen immunohistologic expression may not have a prognostic role in perianal Bowen's disease.

Bowen's disease and internal malignancy. A matched case-control study.

Bowen's disease has been reported as a skin marker for internal malignancy. We conducted a matched case-control study to evaluate the significance of this link. Fifty white men with Bowen's disease diagnosed between 1977 and 1986 at a Veterans Administration Hospital were selected for study. These patients were matched by age, sex, race, and date of skin biopsy to 50 patients with basal cell carcinoma (control group 1) and another 50 patients with other dermatoses (control group 2). The original 50 patients with Bowen's disease include 12 (24%) with various internal malignancies. In comparison, nine patients (18%) in control group 1 and seven patients (14%) in control group 2 had internal malignancies. These numbers do not substantiate a statistically significant increase in the frequency of internal malignancies in Bowen's disease. We therefore conclude that Bowen's disease is not a skin marker for internal malignancy in elderly white men.

Ultrastructure of the epidermal-dermal junction and cutaneous basal lamina in Bowen's disease.

Ten tissue sections from 10 examples of Bowen's disease were excised from paraffin blocks, rehydrated, and incubated in 90% formic acid at 45 degrees C for 18 h. The epidermis was gently removed with the aid of a dissecting microscope, and the remaining dermis with attached basal lamina was processed for scanning electron microscopy. This surface showed a well-preserved basal lamina. The dermal papillae in the areas of Bowen's disease were elongated and had frequent secondary protrusions. The normal 0.5 mu interconnecting corrugations were often replaced by either broad, coarse corrugations or by large areas of smooth-to-undulating basal lamina. This study demonstrates marked alterations in spatial interactions between neoplastic epidermis and underlying dermis in Bowen's disease.

Bowen's Disease of the Finger.

Four cases of Bowen's disease of the finger have been treated, three during the past two years. This form of carcinoma-in-situ should be considered in the differential diagnosis of any persistent scaly and/or crusted lesion of the finger. Bowen's disease in this particular site may be more common than the literature suggests.
