Mycosis fungoides(MF) is a cutaneous T-cell lymphoma of low-grade malignancy characterized by the proliferation of small to medium-sized cerebriform lymphoid cells confined to the skin. It usually shows favorable prognosis, but morphologic transformation occurs in some cases and is often associated with a more aggressive clinical course. Herein we report a case of Ki-1 positive large cell lyrnphoma (Ki-1 LCL) which developed in the plaque stage of mycosis fungoides. Although the lesions responded well to low-dose methotrexate therapy and there was no evidence of local or systemic recurrence until now, continuous follow-up is needed because the prognosis of transformed MF is known to be poor compared with primary cutaneous Ki-1 LCL. We also discussed the differential diagnosis of primary cutaneous Ki-1 positive lymphoproliferative disorders.

Congenital fibrous bands may be found at the gluteus maximus, the gluteus medius,thequadriceqs,the triceps and the deltoideus muscles. Congenital fibrous bands of both gluteus maximus muscles are rare and cause extension contracture of the hip joints. We experienced a case of congenital fibrous bands of both gluteus maximus muscles associated with severe limited flexion of both hips. Almost full flexion of both hips was obtained by excision of the congenital fibrous bands.

A 79-year-old man with balanitis circumscripta plasmacellularis(BCP), presenting as an erythematous constricting band of the inner surface of the prepuce encircling the penile shaft is described. The biopsy specimen of the lesion showed, in addition to the typical histologic findings of BCP, increased fibrosis and decreased amount of elastic fibers which correlate well with our clinical observations. Electron microscopic examination revelaed no viral particles or elastic fibers. Immunohistologically, IgG was found to be the major immunoglobulin class in the plasma cellular inf iltrate.

We report two cases of malignant schwannoma of skin in association with non-familial neurofibromatosis. Case 1, a 47 year old man, had a large subcutaneous tumor on the sacral area and case 2, a 62 year old woman, a painful, ulcerating tumor on the posterior aspect of the left arm. Both cases were histopathologically confirmed as malignant schwannomas and immunohistochemical studies showed 5-100 protein in the tumor cells. After surgical excision of the tumors, case 1 was lost to follow up, while case 2 remained without evidence of disease for more than one and half years.

The question of infectivity and prevalence of Clonorchis sinensis in Cheju province (Quelpart Island) was arisen to authors since the several surveys on the endemic diseases were performed in this island. Therefore, authors decided to solute this question. Then the survey on the possible second intermediate host of Clonorchis sinensis was performed and reported already with negative finding. At present time, authors carried out the collection of all kinds of fresh-water snails through all areas of this island, to confirm the presence or not of Parafossarulus manchouricus, the only first intermediate host of Clonorchis sinensis in Korea . And the following results were obtained. The fresh-water snails collected in the survey were Semisulcospira libertina Gould and Lymnaea ollula Gould. Parafossarulus manchouricus Bourguigant was not collected in this island. It is confirmed that the Clonorchis sinensis can not be prevalent in this island.

We report a case of classic Kaposis sarcoma(KS) in a 74-year-old man who had asymptomatic red-dish-blue or dark-brown macules, papules and nodules on his bo hower extrimities. The biopsy specimen showed typical histopathologic features of FS including a highly vascularized lesion with a proliferation of spindle-shaped cells accompanied by etravasated erythrocytes and variable number of inflammatery cells. Many of the spindle-shaped cells associated with the proliferating vessels in KS lesion expressed factor VIII-related antigen. He was treated with 1500 cGy of radiation(300 cGy per day for 5 successive day. Four weeks after radiotherpy, gross and histopathologic findings were mucl improved and healed leaving hyperpigmentation.

Intraosseous neurogenic tumors are rare and have been reported most commonly in the mandible, possibly because of the long course of the mental nerve within this bone. They have also been reported very rarely in a vertebra. We experienced a case of intraosseous neurilemmoma arising from the body of the first lumbar vertebra, which resulted in paraplegia. The tumor was removed completely through anterior and posterior approaches by staged operation. Postoperative course was uneventful and paraplegia was recovered within three months postoperatively.
