Erythromelalgia(Erythermalgia) is a syndrome of red, warm, congested, and burning painful extremities. Presently, there are three distinct clinicopathological entities: erythromelalgia, primary erythermalgia, and secondary erythermalgia. Secondary erythermalgia usually arises at an adult age either in association with a detectable underlying disorder or with the use of vasoactive drugs. Typically, it responds to proper treatment of the underlying disorder or discontinuation of the causative drugs. A seven-year-old boy presented with persisting burning pain, erythema, and warmth on both of his feet and lower legs, along with hypertension. He had had this condition for 20 months. Laboratory studies of the patient revealed increased urinary catecholamines and plasma renin activity. Various treatment modalities including aspirin, captopril, sodium nitroprusside, labetalol, epidural block, and stellate ganglion block yielded unfavorable results. Herein, we report an intractable case of secondary erythermalgia associated with hypertension in a child.

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.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

We herein report three caes of xanthogranuloma occurring in aduls representing solitary nodule or multiple papules. Blood lipid substances such as cholesterol and triglyceride were normal and extracutaneous manifestatioiis were not found in all cases. Histopathorogic findings commonly revealed a granulomatous infiltrate c(intaining foam cells, foreign body gianf. cells and Touton giant cells as well as histiocytes and lymphocytes.

Thirty-nine patients with pityrosporum folliculitis were investigated clinically and histopathologically. On clinical observation there were numerous, chronic, moderately itchy (64.1%), dome-shaped papules (89.7%) and pustules (66.7%). The most frequent sites of the lesions were the upper portion of the chest (76.9%) and back (56.4%). In biopsy specimens, abundant round and budding yeast cells were seen in a dilated hair follicle. The reptured follicle was observed in 19 specimen (48.7%). The accumulation on inflammatory cells were observed in or around the upper part of the follicle in all specimens. The effect of antimycotic treatment was excellent. After 4 weeks of treatment, 36 patients (92%) were cured and 3 (8%) had improved significantly. KOH/Parker Ink direct smear was done in 20 patients. Blue-colored round and budding yeast cells were observed under a light mcroscope in all patients. We suggest that pityrosporum folliculitis is a common disease of young and middle-aged Koreans.

Psoriasis is a relatively common disorder that affects at least 1-2% of the population, however, the pathogenesis is not fully understood yet. Histopathologically, psoriatic lesion is characterized by hyperplasia of keratinocyte, intraepidermal neutrophil accumulation and activated T lymphocyte infiltration in the dermis. Among many cytokines, IL-8 is known to play a role for the activation and migration for neutrophil and T lymphocyte and for the proliferation of keratinocyte. We performed immunohistochemical staining with anti-IL-8 monoclonal antibody for the active lesion, stable lesion and normal-looking skin of ten psoriatic patients and ten healthy controls. Strong expression of IL-8 in the epidermis and dermis was noted from the active as well as stable psoriatic skins. In the normal-looking skin of the psoriatic patients, only faint expression which is not different from healthy control skin, was noted. These observations indicate that the expression of IL-8 is increased in psoriatic lesion, and IL-S is important for the initiation and maintenance of psoriasis.
