BACKGROUND: CD44 is a family of glycoproteins involved in cell to cell and cell to matrix interactions. Overexpression of CD44v6(variant exon 6) form has been reported in several malignant tumors such as stomach cancer, uterine cervical cancer, colorectal cancer, breast cancer and keratinocytic skin tumors, such as, basal cell carcinoma and squamous cell carcinoma. However, CD44 expression in cutaneous T cell lymphoma has not been investigated thoroughly. OBJECTIVE: The purpose of this study is to examine whether there is any difference in the expression of CD44s & CD44v6 between mycosis fungoides(MF), angiocentric T cell lymphoma, subcutaneous panniculitic T cell lymphoma, Ki lymphoma and unspecified peripheral T cell lymphoma. We also evaluated the statistical significance between the expression of CD44v6 and systemic involvement of the diseases. METHODS: Routine paraffin sections of formalin-fixed 33 tissues (11 MF, 8 angiocentric T cell lymphoma, 5 subcutaneous panniculitic T cell lymphoma, 2 Ki lymphoma, 1 unspecified peripheral T cell lymphoma, 2 psoriasis, 2 lichen planus, 2 erythema nodosum) were labeled with anti-CD44 monoclonal antibody using a avidin-biotin-peroxidase complex. Normal skin served as the negative control. RESULTS: 1. Eccrine glands, hair follicles and the epidermis, except the cornified layer, showed positive staining for CD44s. In inflammatory skin diseases, it showed positive staining for CD44s, however CD44v4/5 and CD44v6 stainings were negative. 2. All(4 out of 4) of the tumor stages of MF showed positive CD44s staining, and 3 out of 4 showed positive CD44v6 staining(p=0.024). However, none of them expressed CD44v4/5. 3. All 8 cases of angiocentric T cell lymphoma were positively stained for CD44s, but not for CD44v4/5. In contrast to other peripheral T cell lymphoma, CD44v6 was expressed in 3 out of 8 cases of angiocentric T cell lymphoma. In subcutaneous T cell lymphoma, only the CD44s was expressed, and Ki lymphoma was positively stained for CD44s and negatively stained for CD44v4/5 and CD44v6. 4. In CD44v6 positive angiocentric T cell lymphoma (3 out of 8) and CD44v6 positive tumor stages of MF (3 out of 4), 5 out of 6 patients had systemic involvement suggesting a statistical significance between CD44v6 expression and patient's systemic involvement(p=0.015). CONCLUSION: These results suggest that CD44v6 may serve as a useful prognostic marker in the tumor stage of mycosis fungoides and angiocentric T cell lymphomas.

The number of patients with tinea corporis diagnosed on the clinical findings and KOH examination was 1,709 during the five yea.rs between January 1976 and December 1980, representing l.5% of the total dermatologic out-patients of 105,267 examined at Chilgok Catholic Dermatological Clinic, Daegu, Korea. The annual number of patients with tinea corporis was 84 (0.47% of the total outpatients) in 1976,115 (0.6%) in 1977, and 263 (1.30%) in 1980, but the figure increased markedly in 1976 reaching 616 (2.51%) and 631 (2.89%) in 1980. Of the 1,709 patients, males numbered 793 and females 916. Although the age of peak incidence was in the third decade in both sexes, males outnumbered females slightly before age 19 and, as age advanced, female predominance became marked. The seasonal distribution of patients was interesting: in summer between June and September when the climate is very humid and hot, the incidence was markedly high. From the 1, 709 patients, 1,293 organisms composms of 6 species were isolated and identified. The species isolated were, in order of decreasing frequency, Trichophyton rubrum (622 organisms, 48. 1% of total organisms isolated), T. mentagrophytes (486 organisms, 36. 2%), Microsporum canis (147 organisms, 11. 4%), Epidermophyton floccosurn (29 organisms, 2.2%), M. gypseum (23 organisrns, l.8%) and T. ferrugineum (4 organisms, 0. 3%).

This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.

We report two cases of acquired fibrokeratoma which occurred on the nose and the elbow. A 0.5 cm sized, dome-shaped normal skin colored nodule was found on the nose of a 70-year-old man and a pedunculated, normal skin colored nodule was found on right elbow of on 18-year-old man. Histopathologic findings showed marked hyperkeratosis and acanthosis in epidermis and thick collagen bundles and dilated thin-walled capillaries were predominantly oriented in the direction of longitudinal axis of the tumor. To our knowledge, acquired fibrokeratoma occurring on the nose and the elbow was not reported.

Clinical characteristics of papular-purpuric gloves and socks syndrome consist of a purpuric erythema affecting the hands and feet in a gloves and stocking distribution. It is sometimes associated with fever and oral lesions. The disease is self-limiting and resolves within 1 to 2 weeks. Serological studies have shown that there is an association with parvovirus B19 infection in most patients affected by this syndrome. We report a case of gloves and socks syndrome in a 21-year-old female. She had a 4-day history of papular-purpuric eruptions of the hands and feet in a gloves-and-socks distribution. She also complained of fever(up to 39C) during the first 2 or 3 days of clinical onset. The oral mucosa was normal and there were no palpable lymph nodes. Laboratory and histopathological findings were non-specific. However, human parvovirus B19 DNA was detected in the serum by a polymerase chain reaction. Systemic manifestations were transient and disappeared within a few days, whereas the skin lesions resolved gradually over a period of 2 weeks.

Spindle cell lipoma was first described in 1975 by Enzinger and Harvey as a variant of lipomas. Histopathological findings show the lipomatous tissue to be replaced by a mixture of uniform spindle cells and mature fat cells closely associated with a mucoid matrix and a varying number of collagen fibers. Immunohistochemical staining is reported to give assistance in the differential diagnosis af spindle cell lipoma from other fibrous or neural tumors. Also, it can be used to investigate the origin of the spindle cells. We report a case of spindle cell lipoma in a 41-year-old female. She had a solitary, normal skin colored, bean sized, subcutaneous mass on the forearm. Most of the spindle cells were strongly positive for vimentin, CD34 and NSE, but negative for actin, factor VIII, S-100 protein and neuro- filaments. The tumor was excised. No recurrence was recognized in a 10 month follow up period.

We report two cases of proliferating trichilemmal cyst in a 61-ear-old woman and a 44-year-old woman who had a solitary tumor, on the left temporal area of the scalp and right flank, respectively. Histologically, the tumors were localized in the dermis and corisised of multilobulated cysts. The cyst walls were composed of liquamous epithelium showing trichilemmhl keratinization. Some of the cells had clear cytoplasm and were positive on PAS staining. Individiial cell keratinization, mild nuclear atypia were also found in the cyst walls. For the treatment, surgical excision was performed with sufficiert margin.

We report a case of atypical eruption due to chemotherapeutic agent in a 60-year-old man who presented with asymptomatic, erythematous, 0.5cm in diameter, confluent, and elevated papules and plaques confined to the face. The patient was previously diagnosed with small cell carcinoma of the lung with liver metastasis. Two months after the diagnosis, a first course of chemotherapy including etoposide was started. Five days after starting the chemotherapy, the patient developed a facial eruption. Histopathologic examination demonstrated increased epidermal mitotic figures, cells in metaphase arrest, basal cell layer hyperpigmentation, prominent dyskeratosis, and squamous atypia. The most distinctive histologic feature was the presence of starburst cells, which are markedly enlarged pale staining keratinocytes containing small basophilic fragments of nuclear debris haphazardly scattered throughout the cytoplasm in a starburst pattern.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.
