Digital syndactylization for the treatment of interdigital squamous cell carcinoma in situ (Bowen disease).

Bowen disease, or squamous cell carcinoma in situ, has been described as a premalignant intraepidermal lesion of the skin. Although more frequently occurring on limbs, interdigital presentation of squamous cell carcinoma in situ in the foot has been rarely reported, likely because of undetected development. Excision has been recommended as the treatment of choice; however, removal of these lesions from intertriginous skin may present few options for skin closure. Interdigital syndactylization may be an acceptable option for the treatment of interdigital manifestations of Bowen disease. The authors present a case of interdigital squamous cell carcinoma in situ successfully treated with excision and digital syndactylization. At the 2-year follow-up, there was no recurrence and no digital deformities.

Immunohistology is valuable in distinguishing between Paget's disease, Bowen's disease and superficial spreading malignant melanoma.

Thirty-nine lesions, originally diagnosed as Paget's disease (19), superficial spreading melanoma (13) or Bowen's disease (7), were reviewed. Supplementary immunohistochemistry on routine processed tissue, using antibodies to cytokeratins (PKK1 and M717) and to S-100 protein, was carried out. Two of the lesions, originally classified as Bowen's disease and superficial spreading type malignant melanoma respectively, were reclassified as Paget's disease based on the immunohistochemical findings. Both lesions contained pagetoid cells positive with PKK1. The results indicate that immunohistochemistry may sometimes be valuable in establishing the correct diagnosis in such lesions.

Papillated Bowen disease, a distinct variant.

Bowen disease usually presents as an irregular, asymptomatic, scaly or crusted erythematous plaque that can occur anywhere on the skin. An unusual clinicopathologic variant is described which presents as a well-circumscribed, papillated, exophytic and endophytic, sometimes keratotic lesion. This papillated variant of Bowen disease exhibits keratinocytes with prominent perinuclear halos suggestive of koilocytic change associated with human papillomavirus (HPV) infections. Classic Bowen disease has been associated in previous studies with a variety of HPV types, especially types 16, 18, and 31. Twenty-six patients with papillated Bowen disease were evaluated. The patients included 15 males and 11 females, ranging in age from 33 to 87 years old. Fifty-four percent (14) of the lesions involved the head and neck, 8% (2) involved the trunk, and the remaining 38% (10) involved extremities (including 3 lesions from the hands). Lesions were examined using in situ hybridization with widely screening genomic probes for HPV types 6, 11, 16, 18, 30, 31, 33, 35, 45, 51, and 52. None of the specimens contained HPV DNA from the more common oncogenic HPV types. Given the striking histologic appearance of these lesions, however, this does not exclude HPV infection detectable by more sensitive screening methods such as polymerase chain reaction. Papillated Bowen disease is distinct from other variants, including the verrucous-hyperkeratotic type.

Mucosal oncogenic human papillomaviruses and extragenital Bowen disease.

BACKGROUND: Genital Bowen disease is known to have a strong association with human papillomavirus (HPV) type 16. On the other hand, previous studies of extragenital Bowen disease (EBD) that have used different hybridization techniques have produced discordant results in the detection of mucosal oncogenic HPV. METHODS: Ninety-four samples of EBD from 78 patients were investigated clinicopathologically. DNA extracted from fixed and embedded tissues was analyzed for the presence of the main mucosal oncogenic HPV types 16, 18, 31, and 33 using polymerase chain reaction (PCR) with specific primers described in 1996 by Baay et al., which are particularly well adapted to fixed tissues and give small amplimers. Moreover, 11 EBD of the hands were investigated by in situ hybridization (ISH). RESULTS: Of the 94 extragenital BD obtained from 78 patients, HPV DNA type 16 was detected in 78 cases (83%) from 65 patients (83.3%) by PCR. Nine patients with EBD of the hands (90%) had HPV type 16, and ISH displayed a diffuse hybridization pattern that corresponded to the episomal viral form of HPV DNA. CONCLUSIONS: The current retrospective study of 94 samples clearly demonstrates the high prevalence of HPV type 16 infection in EBD, especially in EBD of the hands. In this study, no specific clinical, topographic, or histopathologic features of any lesions were found to be indicative of the presence or absence of HPV.

[Treatment of paraungual HPV73-positive Bowen disease with imiquimod cream].

Bowen disease - a squamous cell carcinoma in situ - is associated with oncogenic human papilloma viruses (HPV). The association is best established for genital Bowen disease but also holds for extragenital lesions. The immunomodulatory substance imiquimod is used for the treatment of HPV-induced skin disorders. In the case of paraungual Bowen disease, established treatment options as excision, cryosurgery, radiotherapy or laser treatment might cause persistent nail damage. We successfully treated HPV73-positive Bowen disease in this location with topical imiquimod.

Extramammary Paget disease of the scrotum with features of Bowen disease.

The scrotum is an uncommon site for the presentation of extramammary Paget disease (EMPD). We describe a case of EMPD that was discovered in a patient who had been previously diagnosed and treated for squamous cell carcinoma in situ of the scrotum 3 years earlier. Pathologic examination of the current scrotectomy specimen revealed an erythematous patch with areas of pale induration. Microscopic examination revealed areas with the characteristic histology of Paget disease adjacent to areas characteristic of Bowen disease. Immunohistochemical findings demonstrated a strong expression of carcinoembryonic antigen, cytokeratin 7, and low-molecular-weight cytokeratins (CAM 5.2) in both of these areas, giving support to the overall diagnosis of EMPD. High-molecular-weight cytokeratins (34betaE12) were uncharacteristically expressed in the cytoplasm of the Paget cells with equal or greater strength than in the surrounding keratinocytes, suggesting some degree of squamous differentiation. Very few publications have reported the coexistence of EMPD with squamous cell carcinoma in situ, occurring mostly in the vulva. To our knowledge, our case is the first report of scrotal EMPD with features of Bowen disease. Our findings support the theory that primary EMPD arises multifocally from multipotential epidermal cells.

P27 and mib1 expression in actinic keratosis, Bowen disease, and squamous cell carcinoma.

The histologic boundary between actinic keratosis, Bowen disease, and invasive squamous cell carcinoma is not clear in many cases. We determined nuclear expression of p27 (a protein associated with cellular quiescence) and Ki-67 (a marker of proliferation) immunohistochemically in actinic keratosis, Bowen disease, and squamous cell carcinoma to see if differential patterns of expression for p27 exist and how these might correlate with Ki-67 expression. We determined a labeling index for p27-stained nuclei and assessed the pattern of Ki-67 expression. The student's t test was used to evaluate the p27 labeling index. The p27 labeling index was decreased in invasive aggregates of squamous cell carcinoma (76.9+/- 1.1%) when compared with those of normal epidermis (97.2+/- 2.4%), actinic keratosis (95.3 +/- 1.4%), and Bowen disease (98.0+/- 0.5%). Ki-67 was expressed in a scattered to confluent linear pattern in the basal/parabasal cell layer of normal epidermis and actinic keratosis. Keratinocytes in squamous cell carcinoma exhibited Ki-67 in the peripheral layers of the neoplasm and frequently within the tumor aggregates. Ki-67 was observed in nuclei throughout the full thickness of the epidermis in Bowen disease. The staining pattern of Ki-67 in Bowen disease separated this entity from others under study. The combination pattern of p27 and Ki-67 staining can be used to support differentiation of actinic keratosis, Bowen disease, and squamous cell carcinoma.

Pagetoid bowen disease: a report of 2 cases that express cytokeratin 7.

Bowen disease is a variant of squamous cell carcinoma in situ. In some cases a pagetoid growth pattern can be observed with cytologically atypical clear cells arranged singly and in nests. The differential diagnosis of pagetoid Bowen disease includes primarily Paget disease and malignant melanoma in situ, as well as other less common entities. Two cases of pagetoid Bowen disease are described, one in a 65-year-old man with a thigh lesion and the other in a 25-year-old man with a lesion in the penile/scrotal region. Neither patient had clinical evidence of an internal malignant neoplasm. In both cases, the neoplastic cells were positive for cytokeratin (CK) 7 and CK 19 and were negative for CK 18, CK 20, carcinoembryonic antigen, GCDFP-15, c-erbB2, S100, and HMB-45. In aggregate, these findings support the diagnosis of pagetoid Bowen disease. Previously, others have shown that CK 7 is an almost invariable marker of Paget disease. Thus, we report these two cases to illustrate that CK 7 can be expressed by pagetoid Bowen disease and should not be a cause of confusion in the differential diagnosis.

Expression of proliferation-associated proteins (proliferating cell nuclear antigen and Ki-67 antigen) in Bowen's disease.

Bowen's disease and invasive squamous cell carcinoma arising in Bowen's disease (Bowen's carcinoma) were investigated immunohistochemically with regard to their expression of proliferating cell nuclear antigen (PCNA) and the Ki-67 antigen. Both proliferation-associated proteins were found in all layers of the tumours, and were present in nuclei of any size and shape. The nucleoli lacked PCNA immunoreactivity, but they expressed the Ki-67 antigen. The PCNA labelling index was 36.9 +/- 12.6% in Bowen's disease (n = 16), and 40.7 +/- 11.0% in Bowen's carcinoma (n = 3). The Ki-67 antigen labelling index was 43.6 +/- 16.7% in Bowen's disease (n = 16), and 51.7 +/- 11.6% in Bowen's carcinoma (n = 3). Dyskeratotic cells were positive for PCNA and the Ki-67 antigen, suggesting that these cells are not in a post-mitotic state. We conclude that in dyskeratotic cells of Bowen's disease the cell cycle is interrupted by nuclear disorganization.

Photodynamic therapy for large or multiple patches of Bowen disease and basal cell carcinoma.

BACKGROUND: Photodynamic therapy (PDT) using topical delta-aminolevulinic acid (delta-ALA) is an effective treatment for Bowen disease and certain basal cell carcinomas (BCCs), but its place in clinical practice remains to be established. Patients with large and/or multiple lesions of Bowen disease or BCC can represent a considerable therapeutic challenge. We suggest that delta-ALA PDT may be of particular benefit in such patients. OBSERVATION: In an open study, 35 (88%) of 40 large patches of Bowen disease, all with a maximum diameter greater than 20 mm, cleared following 1 to 3 treatments of delta-ALA PDT, although 4 patches recurred within 12 months. delta-Aminolevulinic acid PDT was also used to treat 40 large BCCs, with an identical 88% initial clearance (after 1-3 treatments), with 4 recurrences within 34 months (range, 12-60 months). In 10 further patients with multiple (> or =3) patches of Bowen disease, 44 (98%) of 45 patches cleared following delta-ALA PDT, although 4 lesions recurred over 12 months. In 3 patients with multiple BCCs, PDT cleared 52 (90%) of 58 lesions, with 2 recurrences during 41 months (range, 12-52 months). Treatments were well tolerated, with only 5 patients with solitary large lesions requiring local anesthesia. CONCLUSIONS: delta-Aminolevulinic acid PDT is an effective tissue-sparing modality achieving good cosmesis. We propose that delta-ALA PDT be considered as a first-line therapy for large and/or multiple areas of Bowen disease and superficial BCCs.

Treatment of Bowen disease using the ultrasonic surgical aspirator.

In most cases, patients with Bowen disease lesions can be easily treated by surgical excision and direct closure; however, the ultrasonic surgical aspirator, an instrument in common use in many fields, offers a good treatment alternative with few drawbacks for patients with lesions that are large and/or located in joint areas, areas that are hard to heal, or areas that are surgically problematic such as the ears, nose, eyelids, and mucous membranes. The clinical application of the ultrasonic surgical aspirator in the treatment of Bowen disease promises considerable benefit in terms of patient comfort because removal of the lesion is easy, is noninvasive, and does not require hospitalization or result in restricted mobility. All of these factors, although benefiting patients, particularly the elderly, can also substantially lower the cost of treatment.

[Bowen disease of the nail apparatus. Report of 5 cases and review of the 20 cases of the literature (author's transl)].

Five cases of Bowen disease of the nail apparatus were studied and the 20 cases published to date reviewed. The lesion was characterized by either periungual redness with scaling and erosions, whitish cuticle, hyperkeratotic or papilomatous process, fissure or crusted ulcer in the lateral nail fold or the nail bed with eventual partial or total destruction of the nail plate and sometimes soreness on the pressure. The key of the diagnosis is the histological picture, identical with that of Bowen diseases of other skin areas. Among the 25 cases, Bowen disease was found mainly in males (20 out of 25 patients) on the left fingers (17 out of 25 finger lesions) with particular involvement of the 1st, 2nd, 3rd finger nail. Hallux was concerned twice. The clinical picture can be protean and mimic verrucae, onychomycosis, paronychia, eczema, pyogenic granuloma, verrucous tuberculosis, subungual exostosis, glomus tumor, dermatitis vegetans, amelanotic malignant melanoma, kerato-acanthoma and of course squamous cell carcinoma. Treatment of choice is complete removal of the tumor by plastic surgery otherwise microscopically controlled excision following chemical fixation (Mohs) or fresh tissue technique.

Bowen disease of the eyelid successfully treated with imiquimod.

We present a case of Bowen disease affecting the eyelid that was successfully treated with imiquimod. The clinical presentation, histopathology, and treatment of this case are presented. The tumor was treated with imiquimod for 3 months, leading to complete resolution of the disease both clinically and histopathologically. There was no evidence of recurrence 5 months after treatment cessation. Imiquimod was safely used on the eyelid in this case and may avoid extensive periocular tumor excision and reconstruction in Bowen disease.

Bowen disease and risk of subsequent malignant neoplasms: a population-based cohort study of 1147 patients.

OBJECTIVE: To address the long-standing question of whether patients with Bowen disease are at increased risk of internal malignant neoplasms. PATIENTS: A total of 1147 Danish patients diagnosed between 1978 and 1993 as having Bowen disease at nongenital sites were followed up for 6463 person-years for cancer occurrence up to 16 years after the skin lesion. MAIN OUTCOME MEASURE: Standardized incidence ratios (SIRs)--the ratios of observed-to-expected numbers of cancer--served as measures of relative risk. RESULTS: The observed number of noncutaneous cancers occurring in the cohort (n = 115) was close to expected (n = 103.0) (SIR = 1.1; 95% confidence interval, [CI], 0.9-1.3). However, nonmelanoma skin cancer (SIR = 4.3; 95% CI, 3.5-5.4; n = 83), lip cancer (SIR = 8.2; 95% CI, 2.6-19.1; n = 5), and, among men, leukemia (SIR = 3.2; 95% CI, 1.04-7.5; n = 5) occurred in excess. CONCLUSIONS: Patients with Bowen disease do not appear to constitutionally be at any unusually high general cancer risk. The increased risk of invasive skin and lip cancers is likely due to the common risk factor of UV light.

The proliferative properties of tumor cells differentially correlate with the host immune responses in anogenital Bowen's disease.

Bowen's disease is a squamous cell carcinoma in situ that rarely invades into the underlying dermis. In order to evaluate the relationship between the cytological properties of the tumor cells and the host immune response, we have examined the expression of p53 and proliferating cell nuclear antigen (PCNA), and the number of mitotic cells, clumping cells, koilocytes, Langerhans cells (LCs) and dermal lymphoid cell infiltration in 18 cases of anogenital Bowen's disease. When compared with normal anogenital skins (n = 10), a statistically significant number of p53-positive cells, PCNA-positive cells, mitotic cells, clumping cells, koilocytes and dermal lymphoid cells was observed in the cases of Bowen's disease. Importantly, there existed a very strong correlation between the number of PCNA-positive tumor cells and the number of infiltrated dermal lymphoid cells. Moreover, the number of mitotic cells significantly correlated with the number of intratumoral LCs. The in situ hybridization technique for human papilloma virus (HPV) demonstrated that the HPV-infected Bowen's disease showed a similar histological and immunohistological pattern as the HPV-non-infected counterparts, except for increased koilocyte formation and decreased p53 positivity. The present data suggest that the proliferative activity of Bowen's disease significantly correlates with the host immune reaction, and that the host immune system may differentially recognize the different cytological properties of tumor cells in the Bowen's disease.

Venereal warts vs Bowen disease. A histologic and ultrastructural study of five cases.

Verrucous growths of the genitalia in young patients are usually condylomata acuminata. In five cases this type of genital lesion, viewed by light microscopy, showed dysplastic cellular changes of Bowen disease, a diagnosis that was further confirmed by electron microscopy. Bowen disease should be included in the differential diagnosis of verrucous lesions of genitalia in young people and should be ruled out by histologic examination.

Immunohistochemical distinction of Paget's disease from Bowen's disease and superficial spreading melanoma with the use of monoclonal cytokeratin antibodies.

The differentiation of Paget's disease from Bowen's disease and Pagetoid superficial spreading melanoma may represent diagnostic difficulties. The special stains used in their differential diagnosis are nonspecific and not always sensitive. Therefore, the expression of cytokeratins of different molecular weights (54, 57, and 66 kilodaltons [kD]) was studied in 26 intraepithelial neoplasms in formalin-fixed paraffin-embedded tissues with the use of an avidin-biotin complex (ABC) method with monoclonal cytokeratin antibodies. These included 9 cases of Paget's disease, 11 cases of Bowen's disease, and 6 cases of Pagetoid superficial spreading melanoma. Paget cells from vulva and breast were always positive for 54-kD cytokeratin, variable for 57-kD cytokeratin, and negative for 66-kD cytokeratin. The neoplastic cells in all 11 cases of Bowen's disease were stained for 57-kD and 66-kD cytokeratins but not for 54-kD cytokeratin. The neoplastic cells in all cases of melanoma did not express any of the cytokeratins studied. The results indicate that antibodies to cytokeratins of different molecular weights may be used as a diagnostic tool in the distinction of Paget's disease from Bowen's disease and melanoma.
