We present a 40-year-old woman who had a well circumscribed, pea sized red-brown glistening erosive papule on the foreskin of clitoris for four months which had been resistant to various forms of treatment. Histopathologic examination revealed flattened epidermis with lozenge keratinocytes and watery spongiosis, In the upper dermis, dense bandlike infiltration of plasma cells, endothelial proliferation, and capillary dilatation were noted. Peroxidase-antiperoxidase stain showed polyclonal pattern of reaction in the cytoplasm of plasma cells.

Stratum corneum was obtained from 10 healthy individuals aged 23 and 24 years, in order to observe morphological differences in a three-dimensionsl structure of stratum corneum from 3 anatomical sites, i. e., flexor surface of the forearm, abdomen, and palm. The stratum corneum obtained by the skin surface biopsy was ohserved under a scanning electron microscope(SME). The surfaces of stratum eorneum obtained by the replice, technique were observed under a stereomicrascope(SM). The results were as follows : 1) SEM observation of the posterior surfaces of the stratum corneum from the skin surface biopsies of the flexor surface of the forearm and abdomen showed divisions with folding lines which were elliptic in the forearm and squere in the abdomen. But there were no similar folding linea in the palm. Among the 3 anatomiral sites, overlapping corneocytes on the palm were most prominent. On a higher magnification, small pits and fine wrinklings in the forearm, fine wrinklings in the abdomen, and villous projections in the palm were observed respeeti vely. 2) SM observation of the stratum corneum from the negative replica of the flexor surface of the forearm, abdomen, and palm showed divisions with folding lines which were X-shape a.t the site of their crossinga in the forearm, *-shape in the abdomen, and linear shape in the palm, Among the 3 snatomical sites, tiny holes on the palm were most prominent. Follicular openings were observed on the pa1m, and abdomen,

We report a case of fibrous hamartoma of infancy in a 7-month-old male infant, in which a solitary, asymptomatic, walnut-sized, nomal skin-colored plaque occurred on the left middle back for about one month. Histopathologic findings showed the distinctive features of fibrous hamartoma of infancy, ie, trabeculae of dense collagenous tissue, whorls of immature spindle cells within a mucoid matrix, and interspersed mature adipose tissue, in the lower dermis. The lesion was excised without recurrence.

We herein report a case of keratoderma showing the combined clinical manifestations of striate and marginal keratoderma. The patient was a 18-year-old giri who about a year ago noticed slightly yellowish, well-circurnscribed, hyperkeratotic plaques on the volar aspect of the fingers and palms of both hands in a linear pattern with bands of hyperkeratotic plaques at the edeges of the 2nd fingers. We also found hyperkeratotic plaques on the both soles which were confined to sites of pressure. She denied a history of any chronic pressure or trauma. There was no family member showing the same clinical features. The histopathological findings from the palm, volsr aspect of finger and a sole revealed marked hyperkeratosis, hypergranulosis, and acanthosis.

Wegener's granulomatosis is a systemic necrotizing vasculitis of unknown cause. The disease is characterized by the involvement of the upper airway, the lung, and the kidney. Skin lesions are frequent and the most common lesion is purpura distributed on the limbs and trunk. A 34-year-old female showed recurrent purpuric macules on the both lower extremities and buttocks. The patient. showed nasal septal perforation with saddle nose deformity and C-ANCA positivity. Histopathologic findings of purpuric lesion revealed the features of necrotizing vasculitis. The histologic specimen from the nasal cavity showed chronic inflammation with granuloma formation and kidney showed focal necrotizing glomerulonephritis. Therefore, we treated the patient with prednisolone and cyclophosphamide having diagnosed Wegener's granulomatosis.

Following chemotherapy and radiation treatment for infiltrating ductal carcinoma of the left breast, a 50-year-old woman presented with a child's palm sized, crusted patch and surrounding peanut sized granulated nodules on the lesion, which was diagnosed as primary cutaneous aspergillosis caused by Aspergillus fumigatus. No evidence of involvement of other organs or of systemic dissemination by Aspergillus femigatus was found. Also the patient exhibited no other apparent systemic immunologic defects. Extensive excision were performed and the patient received treatment with amphoteriein B. No evidence of recurrent fungal infection was noted during 6 months of follow-up.

Dermatophytes have been demonstrated infrequently in the dermis, subcutis, lymph nodes, bones and other tissues. A few cases of deep granulomatous cutaneous infections due to dermatophytes have been reported, but Trichophyton mentagrophytes are extremely rare. We report two cases of T. mentagrophytes infection showing unusual granulomatous manifestations. A 63-year-old woman presented with multiple erythematous patches and nodules on both arms and lower extremities for 3 months. The second patient was a 69-year-old man who had erythematous annular plaques on the dorsum of the left hand for 4 months. Histopathologic examinations of the skin lesions of both patients showed chronic granulomatous inflammation with fungal elements. The biopsy specimens yielded T. mentagrophytes on culture. The skin lesions were cured after administration of itraconazole.
