Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

We experienced a case of sparganosis developed in the dorsum of penile shaft where, we think, is the very rare site of sparganosis reported in Korea. The patient, a 23 year-old Korean soldier, had slight tender thread-like linear subcutaneous mass on the dorsal aspect of penile shaft for 1 month prior to coming to us. The skin lesion was not palpated when the penis was erect. He had experience of intaking raw-snakes intermittently(5 times) since 2 years ago.

We describe herein a case of tick bite ocurring to a 23-year-old man who has a characteristic lesion clinically and histopathologically. The tick(Ixodes sp.) was still attached to the brownish and erythematous, indurated skin of the scrotum. The engorged tick which was carefully removed from the skin with a scalpel was 8.7mm in length and 5. 5 mm in width. Histopathologically, characteristic amorphous eosinophilic materigl is deposited around a round space where the hypostorne of the tick was inserted. Heavy inflammatory cell infiltratton in the mid and lower dermis is composed mainly of neutrophils and eosinophils. A certain area of the lower dermis shows edema and capillary dilatation along with the mixed inflammatory cell infiltration, TVide excision of the indurated lesion including the tick was done. The clinical and hsitopathological findings of the tick bite was discussed.

Acrokeratoelastoidosis of Costa is a rare palmoplantar keratoderma with autosomal dominant inheritance. It is clinically charaeterized by small, firm, yellowish, shiny, translucent papules occumng over the dorsal hands, the knuckles, and the lateral margine of the palms and soles. Histologically, the characteristic features are hyperkeratosis, aeanthosis, and most strikingly, fragmentation of coarse elastic fibers within the dermis. The lesions usually begin in early childhood and progress slowly. We herein report two familial cases of acrokeratoelastoidosis of Costa showing typical clinic1 and histopathological features.

Microsporum gypseum, long considered to be of animal origin, has recently been found to be soil inhabitating fungus and abundant in soil throughout the world. M. Gypseum infections tend to increase nowadays in Korea. Nineteen cases of ringworm caused by M. gypseum were reported in Korean literature until 1980 to the best of our knowledge. We present 5 cases of M. gypseum infection confirmed by culture findings on Sabouraud agar media and microscopic examination. The first case was 4 year-old boy with solitary coin sinzed pruritic annular erythernatous plaque ontaining papules, pustules and scales on the right cheek of on month duration. The second case, 7 year-old boy, had solitary walnut sized ovoid plaque consisted with papulopustules, oozing and peripheral scaling on right cheek of one month duration. The third case, 5 year-old boy, had solitary egg sized pruritic erythematous plaque with papuIes, scales and crust on the right lower leg of three weeks duration. The fourth case, 63 year-old female, had solitary egg sized sharply demarcated erythematious scaly patch with central clearing on nose and. nasolabial area of 10 days duration. The last case was 2 year-old girl with solitary coin sized annular erythematous scaly pIaque on left lower leg of two weeks duration.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

BACKGROUND: Partial unilateral lentiginosis (PUL) is a rare pigmentary disorder characterized by grouped multiple lentigines on otherwise normal skin that histologically have the typical features of lentigo. This entity has been only rarely reported in the Korean population. OBJECTIVE: The purpose of this study was to evaluate clinical and histopathologic characteristics, association with other disorders, and differential diagnosis of PUL. METHODS: We reviewed our experiences of thirteen cases of PUL which had been collected in our dermatology clinic during the 6-year period between 1993 and 1998. RESULTS: Twelve patients were female and one was male. In 3 patients the lesions appeared after the age of 20 years. Ten patients had the lesions on the upper part of the body, the neck being the most common location. No bias was shown in terms of the side of the body affected. Cafe-au-lait macules (one to three) were found in six patients, axillary freckles were observed in two. Histopathologic examination of biopsy specimens commonly showed hyperpigmentation of the basal layer, elongation of rete ridges, and an increased number of melanocytes. There ,was no evidence of associated disorders or family history. CONCLUSION: Based on this data, we confirmed that PUL is a benign, idiopathic lentiginosis with no commonly associated abnormalities. Furthermore, we believed that PUL is not uncommon in Korean people.

We report herein a case of subcutaneous granuloma annulare occured in a 3-year-old girl who had 7 subcutaneous nodules on the scalp, lumbar area, buttock, right tibial area and both ankles. liistopathologically, multiple foci of complete and incomplete collagen degeneration surrounded by histiocytes in a palisading arrangement were seen in the subcutaneous layer. Some vessel walls were thickened and infiltrated with inflammatory cells and many eosinophils were scattered among the inflamrnatory cell infiltrate around the palisaiing granuloma. Five of the lesions disappeared spontaneously and other s decreased in size without specific treatment in 2 months.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.
