Trichotillomania is the cllinical syndrome of alopecia resulting from the repetative pulling, plueking and breaking of ones own hair. We report four cases of trichotillomania in 10 year old children. The lesions were limited to the scalp. All of them had psychiatric problems in the school or home according to a psychiatric consultation. The histopathologic examinatiorii revealed a normal number of hair follices, empty hair follicles and no inflammatory reaction. The treatment led to hair growth in three cases but one case did not respond to the treatment.

The monoclonal antibody Ki-1(CD30) was first described in 1982 and was reported to react selectively with Reed-Sternberg cells in Hodgkins disease, highly activated B and T cells and large cell lymphomas of both T-and B-cell origin. Lymphomatoid papulosis(LyP) is characterized by recurrent erythematous papules or nodules that undergo spontaneous healing with hyperpigmentation and scarring. Histologically, two major types of LyP can be distinguished: type A is characterized by the presence of variable numbers of Ki-1+ large, atypical lymphocytes with some Reed-Sternberg like cells and type B is characterized by Ki-1- atypical cerebriform mononuclear cells similar to those in mycosis fungoides. We report a case of Ki-1+ lymphomatoid papulosis which was histopathologically recognized as a type B lesion but represented a Ki-1 positive reaction.

Hailey-Hailey disease(benign familial chronic pemphigus) is a rare autosomal dominant disorder characterized by blisters at sites of friction such as the neck, axillae and groin which are caused by suprabasal epidermal acantholysis. We report two cases of Hailey-Hailey disease in the one family. One of the two cases has asymptomatic multiple longitudinal white bands in the fingernails associated with typical skin lesions. The nail lesions have not been described until reported by Burge in 1992 and it may be a characteristic finding in Hailey-Hailey disease.

We report two cases of recurrent extramarnmary Pagets disease after wide local excision. Both cases involved the scrotum and the penoserotal junction, respectively. On histopathological examination, we could observed many Paget cells confined to the epidermis and the hair follicle, but not invading the underlying dermis in both cases. There was no evidence of internal malignancy. Both cases were treated with wide local reexcision.

Kaposis sarcoma is a multicentric neoplastic vascular tumor involving the skin or internal organs. We report a case of classic Kaposis sarcoma in a 69-year-old male who had positive serum cytomegalovirus antibodies and disseminated multiple erythematous to purplish colored confluent papules and edema on both lower legs. The histopathological finding showed abnormally proliferated and dilated vessels, vascular spaces, spindle cells, and extravasated erythrocytes. He was treated with radiotherapy, but died due to ventricular tachycardia.

BACKGROUND: The effects of intralesional recombinant alpha-2 interferon(IFN) in the treatment of basal cell carcinoma(BCC) and actinic keratosis(AK) would be of value in selected patients. OBJECTIVE: Our purpose is to evaluate the differences of cellular immune reactions between the responded and the unresponded cases treated with IFN. METHODS: We treated five patients with BCC and two patients with AK with the intralesional injection of recombinant alpha-2 IFN. We performed immunohistochemical stainings with paraffin-embedded specimens from the pretreated and posttreated skin lesions. RESULTS: Four patients(three with BCC and one with AK) were healed and three patients showed improvement after treatment. In immunohistochemical stainings, there was an increased number of T cells in the dermal infiltrate of the responded cases but not in the unresponded cases. CONCLUSION: Intralesional IFN may induce T cell-mediated immune response at the site of the tumor by immune modulation.

Malignant melanoma is an uncommon tumor in Korea. To the best of our knowledge, we could not find malignant melanoma with multiple myeloma in Korean literature. A 57-year-old male patient had a 4×5 cm sized, irregular bordered, dark brownish plaque on the left sole, which has extended gradually since about 1 year ago and showed an occasional bleeding tendency. Laboratory examinations revealed a low hemoglobin level, rouleaux formation on peripheral blood, monoclonal gammopathy of IgG-kappa type and Bence-Jones proteinuria. Bone marrow aspiration findings showed markedly increased immature plasma cells suggesting multiple myeloma. Histopathologic findings of the skin biopsy from the left sole revealed proliferation of atypical melanocytes. We performed a surgical excision with a skin graft for malignant melanoma and chemotherapy (melphalan, vincristine and prednisolone) for multiple myeloma.

A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

BACKGROUND: Glutathione S-transferase(GST) is a family of isoenzymes that play an important role in protecting cells from cytotoxic and carcinogenic agents. Strong activities of GST-Pi in the epithelial tissues was observed in the upper layer of skin, gastrointestinal tract and placenta which have been exposed to exogenous chemicals. OBJECTIVE: This study was done to observe the distribution pattern of GST-Pi in normal, acute and chronic psoriasis or eczematous dermatitis, using paraffin-embedded human skin tissues. METHODS: Twenty-one psoriatic and twenty-six eczematous dermatitis specimens were observed by immunohistochemical staining using an anti-rabbit GST-Pi polyclonal antibody. RESULTS: Stainining reaction for the GST is weakly to moderately stained in the normal epidermis. In the acute stage, upper layer shows weak and moderate staining in the lower epidermis of the psoriasis and eczematous dermatitis but in the chronic stage GST-Pi are noted strongly expression in upper epidermis. CONCLUSION: Immunohistochemical staining for the GST-Pi reveals a more abundant distribution in the chronic stage rather than in the acute stage of psoriasis and eczema tous dermatitis, showing no disease specificity. Therefore it is suggested that the detoxifying capacity decreases in the acute stage of above dermatosis.

We report 6 cases of sporotricosis including 3 cases of lymphocutaneous type and 3 cases of fixed cutaneous type. There were 3 males and 3 females patients in the age between 5 to 63 year-old age. Clinically, histopathologically and mycologically, we diagnosed the cases as the sporotrichosis. And then case 1 and 2 were treated with potassium iodide for 9 weeks and 15 weeks duration. Case 3, 4, 5 and 6 were treated with itraconazole for 10-14 weeks duration. All patients were almost healed without recurrence.
