Pyodermatitis-pyostomatitis vegetans: report of a case and review of the literature.

Pyodermatitis-pyostomatitis vegetans is a benign, rare disorder characterized by a pustular eruption in the oral mucosa and vegetating plaques involving the groin and axillary folds. Its association with inflammatory bowel disease is well established. We report the case of a 49-year-old-white man with ulcerative colitis who manifested a vegetating, annular plaque in the left inguinal region of 2 months' duration. Oral examination disclosed an erythematous mucosa with multiple painful pustules involving the labial and gingival mucosa. Histopathologic study demonstrated epidermal hyperplasia and an inflammatory infiltrate composed mostly of neutrophils and eosinophils, grouped into microabscesses within the epidermis and with a bandlike configuration in the upper dermis. Results of direct and indirect immunofluorescence studies were negative. We discuss the differential diagnosis between pyodermatitis-pyostomatitis vegetans and pemphigus vegetans.

Panniculitis mimicking lupus erythematosus profundus: a new histopathologic finding in malignant atrophic papulosis (Degos disease).

We present the case of a 57-year-old woman with a 1-year history of a cutaneous eruption clinically and histopathologically characteristic of Degos disease. In one of the two cutaneous biopsy specimens taken from the trunk lesions, the histopathology consisted of necrosis and sclerosis of the subcutaneous lobules, a finding that to our knowledge has not been previously described in the cutaneous lesions of Degos disease. Two months after cutaneous biopsies were taken, the patient developed ptosis and an episode of acute abdominal pain; intestinal perforation and many characteristic lesions of visceral Degos disease involving the entire small bowel were noted at laparotomy.

Sebaceous carcinoma of the vulva.

Extraocular sebaceous carcinoma is an uncommon neoplasm usually localized on the head and neck. Sebaceous glands are abundant on the vulva, but vulvar sebaceous carcinoma is an uncommon neoplasm. To our knowledge, there are only five previously reported cases of sebaceous carcinoma on this location. We report an additional case of vulvar sebaceous carcinoma associated with Bowen's disease in the overlying epidermis. The patient also had bowenoid papulosis involving the skin of labia majora. We analyzed by immunohistochemistry, Southern blot hybridization, and polymerase chain reaction (PCR) techniques for the presence of DNA of human papilloma viruses (HPVs) in the specimen of sebaceous carcinoma and in lesions of bowenoid papulosis. Immunohistochemistry, Southern blot hybridization, and PCR studies in specimens of bowenoid papulosis lesions and sebaceous carcinoma did not detect DNA of HPVs. A significant increase in intranuclear p53 staining was demonstrated in several areas of neoplastic aggregations of sebaceous carcinoma.

An outbreak of tinea gladiatorum in Lanzarote.

Canary Islands wrestling is a variant of the sport played exclusively in that region, and is associated with close participant contact. An outbreak of a fungal infection, so-called tinea gladiatorum, amongst such wrestlers in Lanzarote, one island in the archipelago is now described. 102 wrestlers from the eight teams on the island were examined; some of the clubs are 50 km apart; 45 wrestlers (44.1% of those examined) were noted to be affected. To our knowledge, this is the largest reported series of patients with tinea gladiatorum and the only one to demonstrate such infection in a variety of geographical locations.

Acquired hypertrichosis lanuginosa: case report and review of the literature.

Acquired hypertrichosis lanuginosa is a rare cutaneous disorder usually associated with internal malignancy that consists of the development of abnormal hair growth of the lanugo type, often confined to the skin of the face and neck, although other areas also may be involved. We report on a 66-year-old woman with a metastatic ductal infiltrating carcinoma of the breast who developed growth of fine lanugo type hair on her face and progressive growth of the hair of eyebrows and eyelashes. We review the literature on this uncommon paraneoplastic cutaneous disorder emphasizing the pathogenic mechanisms that have been proposed to explain the striking overgrowth of lanugo type hair.

Spinulosis of the face as a manifestation of demodicidosis.

We describe a 78-year-old woman with polycythaemia rubra vera who had multiple tiny follicular hyperkeratotic spicules on the cheeks. She was receiving treatment with oral hydroxyurea, but no topical agents had been applied to her face. Histopathological study demonstrated numerous Demodex folliculorum mites within dilated follicular infundibula, and we consider that the mites were playing a part in the aetiology of the skin lesions.

Cutaneous manifestations of infection by nontuberculous mycobacteria.

Cutaneous infections by nontuberculous mycobacteria (NTM) are not usual but their relative importance has changed during the last few years and still further changes are expected. This study comprised 13 patients from whom NTM were recovered from skin biopsy specimens, sinus exudates or cutaneous abscesses. All samples were processed according to standard methods, and the isolates were identified by biochemical testing. Skin biopsy specimens, when available, were processed for histopathological study. The clinical records of the patients were reviewed, and the relevant clinical, microbiological and epidemiological data collected. The clinical manifestations were noted to be relatively nonspecific and consisted of draining sinuses, abscesses, ulcers and nodules with multicentric or sporotrichoid patterns. Tissue culture isolated Mycobacterium fortuitum complex in nine patients, M. avium in three, and M. marinum in one. In the nine patients studied by histopathology, various patterns were observed. These included dermo-hypodermal abscesses, suppurative granulomas, tuberculoid granulomas and granulomas with a perifollicular distribution. Cutaneous lesions can thus be the first and the only sign of NTM disease, and culture still remains the definitive diagnostic procedure.

Histopathology of cutaneous reaction to granulocyte colony-stimulating factor: another pseudomalignancy.

Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic growth factor (HGF) with many applications in cancer therapy. The most important applications are reduction in the incidence of febrile neutropenia, acceleration of neutrophil recovery after chemotherapy or bone marrow transplantation, and mobilization of progenitor cells. Many cutaneous adverse reactions associated with HGF have been reported in recent years, including injection site reactions, pyoderma gangrenosum, Sweet's syndrome, cutaneous leucocytoclastic vasculitis, and widespread folliculitis. The presence of large histiocytes on the dermis between collagen bundles has been proposed as a characteristic histopathologic finding in cutaneous eruptions secondary to granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor. We report on a patient with a high-risk ductal infiltrating carcinoma of the breast who received high-dose chemotherapy (HDC) with peripheral blood progenitor cell (PBPC) rescue. The patient received G-CSF after PBPC for a faster granulocyte recovery. She developed a cutaneous eruption located on back, buttocks, axillae, groin and sites where electrocardiography electrodes had been placed. From the histopathological point of view, the eruption was characterized by the presence of numerous large, atypical histiocytes in the dermis with several mitotic figures, mimicking involvement of the dermis by a malignant process.

Cutaneous metastases from prostatic carcinoma.

Cutaneous metastasis from carcinoma of the prostate is a rare phenomenon. When it occurs, metastases usually appear as multiple nodules involving the suprapubic area and the anterior aspect of the thighs. We report on two cases of cutaneous metastases from prostatic carcinoma, one of them presenting the stereotypical clinical and histopathological findings, whereas in the other one cutaneous metastasis consisted of a morphea-like plaque on the chest. Histopathologically, the later case revealed accumulations of neoplastic cells distributed in a folliculotropic pattern. In both examples immunohistochemical study with prostatic specific antigen (PSA) confirmed the prostatic origin of the metastases. We review the literature on this subject.

Unilateral areolar sebaceous hyperplasia in a male.

We report a case of areolar sebaceous hyperplasia involving the right mammary areola in a 49-year-old male. Areolar sebaceous hyperplasia, an uncommon entity first described by Catalano and Ioannides in 1985, is characterized clinically by yellowish thickening of the areolae and histopathologically by large numbers of mature hyperplastic sebaceous lobules connected to the skin surface through short, hairless infundibular canals. Since its original description, only two additional reports have been published. To our knowledge, our patient is the first reported of areolar sebaceous hyperplasia in a male.

Congenital nasal comedones--report of three cases.

We report on three patients with black or white comedones arranged along the nasal groove in the distal third of the nose between the alar and triangular cartilages. This peculiar disorder is probably more common than would appear from the small number of cases so far reported in the literature.
