ABSTRACT
We observed clinical and microscopic features in 34 patients with dermatofibroma. Of these features, peculiar epidermal changes were observed in six (17.6%) cases. These were keratoacanthosis(1 case), acanthosis nigricans-like(2 cases), pseudoepitheliomatous hyperplasia.(1 case), hair follicle-like basal cell proliferation(1 case) and early basalioma-like(1 case) changes.

We have experienced a patient (4-year-old female) with a granular cell tumor (GCT), Examination of patients skin showed a bean sized asymtomatic firm nodule on the left baek. Exciaional biopsy and histopathologic examination were perforrned under the impression of angiolipoma. The specirnen revealed a distinctive picture of GCT.

By recent advance of immunologic techniques, it made possible to measure the immune cells and NK cell activity in peripheral blood of various immune altered eonditions. NK cell activity is related not only to malignancies but also to viral infectiona. The facts that the impairment of cell mediated immunity inducea the herpes zoster infection and frequent association with herpes zoster in the patienta with malignancy promote author to atudy the alteration of immune cells and NK cell activity in peripheral block. So author evaluated irnmune cells and NK cell activity of 18 patients with berpes zoster. The results are as follows; 1. The mean value of T cells, T cells showed significant differences between patients group(58.4-i-6.9%, 33.7-+11.7%) and normal healthy control group (68. 6+ 4. 7yo, 44. 2+-7. 0%) but T,' and B cells showecl no significant between patientagroup(6.9-+2.4%, 12.5+-5.7%) and.controlgroup(7.8-1.5%, 13.9-+2.3g%), statistically. 2. The mean value of NK cell activity in patients with herpes zoster group (62. 9+-ll. 2%) showed no significance cornpaired with the mean value of normal healthy control group(57. 9+-l4. 8%), statiatically.

Marjolin's ulcer seated upon an old cicatrix, especially old burn scar, which may chiefly degenerated into a squamous cell carcinoma with propensity for metastasis. We are experienced two cases of Marjolins ulcer recently. A 54-year-old male who had a Marjolins ulcer(15x40cm) on his left lower extremity. He was experienced burn at the age of eight and rice sized ulcer was developed at the site of burn scar about 21 years ago. The ulcer progressively enlarged in size to reach 15x40cm for 21 years. The pathologic diagnosia was squamous cell carcinoma grade 1, but cancer cells invaded to deep dermie and subcutaneous tissues. Severe skin lesion and irreversible osteoporotic degeneration on knee joint of affected limb were present. So he was treated by high above knee amputation. Another 58-year-old female who had a Marjolins ulcer(10x20cm) on her right lower extremity. She was experienced burn at the age of forty eight and bean sized ulcer was developed at the site of burn scar about 1 year ago. The pathological diagnosis was squamous cell carcinoma grade 1 and invasian of cancer cells was limited upper dermis. On lymph node biopsy, the histological diagnosis was within normal limit. So she was treated radical surgical excision with split thickness skin graft(Mesh).

We report a case of linear scleroderrna associated with severe musculoskeletal atrophy of Ieft arm or disabling pansclerotic morphea of children. The patient was 11 year-old girl who has 8 years history of linear violaceoushued atrophic plaques on left arm and anterior chest, left sboulder region in a circumscribed sclerotic lesion. She had a history of injury on left forearrn at 3 years of age. One, month later, erythematous swelling and hardening of skin on left hand were developed and then progressed rapidlyfto other area for one year. However there was no signs of dyspnea, dysphagia, Raynauds phenomenon, myalgia, weakness and photcsensitivity. Diagnosis was confirmed by the characteristics of clinical features and histologic findings of skin and muscle and laboratory findings. As a therapeutic trial, low dose D-penicillamine was attempted.
