ABSTRACT
A 17-year-old male was presented withfpruritic grouped erythematous papules on the face, chest, upper back, both axillae, and genital area. The histologic picture of a benign papilloma and spongiosis around the acrosyringium were prominent findings. The term acrosyringeal epidermal nevus is proposed for this histological picture, and some explanations for its pathogenesis are suggested.

We report two cases of extramammary Paget's disease associated with ad enocarcinoma with metascases. Histologically, Iaget cells in the epidermis and the hair follicles and adenocarcinoma in the der mis was observed in both cases. Of special interest was the demonstration of Eaget cells extending from the involved epidermis to the underlying dermis in case 2, There were metastatic lesioris of 3rd lumbar vertebra in case 1 and of the liver and lymph nodes in rase 2.

Clinical history and dermatological examinations were performed in 51 patients with contact dermatitis due to metal working fluid who were working at the metal industry. Patch tests were also performed with standard series and oil cooling fluid series. Chronic lichenified eczema such as lichenified and fissured was the most common clinical type(45.1%). 19 patients had positive reaction to either one or more of the standard series and oil & cooling fluid series. We found ammoniated mercury chloride was the most common sensitizer in standard series, followed by potassium dichromate, 4-phenylendiamine dihydrochloride, cobalt chloride, nickel sulfate, quinoline mix and cabra mix. Microbiocide was the most common allergen(4 of 6 positive result in oil & cooling fluid series.

We report a case of sebaceous hyperplasia showing linear arrangement in a 13-year-old girl. The lesion was found at birth and became prominent gradually. Multiple small discrete yellowish papules were arranged in a linear pattern on the temporal srea of the face. Unusual, incidental histopathologic finding was a sebaceous lobule lying in a dilated infundibular portion, which appeared to represent transfollicular extrusion of sebaceous lobule as a natural phenomenon.

One hundred and nineteen cases of congenital melanocytic nevi diagnosed clinically and/or histopathologically st Departments of Dermatology, Plastic surgery and Pedia trics of 7 branch hospitals of Catholic University Medical College from October, 1986 to October, 1988 were reviewed by their incidence, distribution, age, size and elinical findings. The results were summarized as follows . l. Among 2g73 newborn babies, 33(1.5%) melanocytic nevi were found clinically. 2. Amomg 119 congenital melanocytie nevi, 31 located on the head and neck area, 47 on the trunk, and 41 on the extremities. 3. Thirty (252%) were less than 0.6cm in greatest diameter, 42(353%) nevi 0.6 to 15cm, 15(12.7%) nevi 1.6 to 3.0cm, 26(218%) nevi 3.1 to 10.0cm and 6(5.0%) nevi greater than 10.0cm. 4. a) Seventy three nevi(613%) were uniform in color and 46(38.7%) were mixed brown r black with variable proportion. b) Fifty three(44.5%) nevi were flat, 36(303%) were slightly elevated, 17(14.3%) had pebble stone appearance and 13(10.9%) were dorne shaped. c)Thirteen(11%) nevi had terminal hair on the surface.

Phakomatosis pigmentova.scularis is a disease complex with dermal melanocyto sis such as nevus of Ota, nevus of Ito, or Mongolian spots and extensive hemangiomatous change such as nevus flammeus, which are associated with systemic organ involvement. We report a 23-year-old female, who showed bilateral nevus of Ota and nevus of Ito with widespread nevus flammeus and Mongolian spots since birth. She was also associated with megalocornea due to congenitol glaucoma and cataract.

Candida albicans produced a karatinolytic proteinase (KPase) or C. albicans producing proteinase (CAPP), a proposed new term for this enzyme, and Trichophyton mentagrophytes also produced KPase when cultivated in liquid medium containing human stratum corneum (HSC) as the nitrogen source, but were unable to do so when cultivated in sabouraud dextrose broth. Purified KPase from the culture supernatants of C. albicans had a molecular weight of 42,000 and an optimum pH at 4.0. The KPase was found to belong to the carboxyl proteinases group and its activity was strongly inhibited by pepstatin. Both fungi were able to grow by secreting KPase which digested HSC for nutrients. KPase from both fungi had high activity in each optimum pH, such as weakly acidic pH on C. albicans and neutral pH on T. mentagrophytes to adapt their surrounding environment by changing the environmental pH into their own optimum pH.

A 23-year-old male patient had 65 nodules of 0.2~0.7 cm in diameter nn scrotum. Elliptical excision was done to remove the nodules situated on the middle part of the scrotum. For small multiple nodules on the lower part of the scroelectrocogulation and curretage was performed. Excellent results were obtained by two modalities of treatment.

We report herein a case of subcutaneous granuloma pyogenicum developed on the fourth interdigital space of right foot of 36-year-old housewife. Histopathological findings showed characteristic lobular capillary hemangioma. The subcutaneous nodule had a thick fibrous capsule and were composed of multiple, confluent cellular, angiomatous lobules separated by loose fibrous tissue. Most lobules contained round, oval or angular capillaries, lined by proliferated prominant endothelial cells projecting into the lumina of the vessels. Clinically, the lesion was a tender subcutaneous nodule with macerated surface aind soft corn or traumatic epidermal cyst were considered in the differential diagnoses.

The relation of atopic dermatitis to various manifestations of ocular disease has been documented in the dermatologic literature. Several lines of evidence suggest that patients with atopic dermatitis have defective ceil-mediated immunity and decreased cellular hypersensitivity. In this paper, we presented two cases of atopic dermatitis developing ocular complication and abnormal immune response in vivo and in vitro during the course of atopic dermatitis.
