With a view to investigating the distribution of keratinophilic fungi in soil according to latitudes in south Korea, soil samples were collected at 81 sites in 17 areas in different latitudes across the country and keratinophilic fungi were isolated by means of Vanbreusegherns technique. The results are summarized as follows : 105 strains of keratinophilic fungi were recovered from 56(69.2%) out of 81 samples. Isolated fungi were composed of 41 strains of Trichophyton ajelloi, 24 stains of Chrysosporium species, 20 strains of Microsporum gypseum, and 20 strains of M. cookei. Frequency of isolation of keratinophilic fungi tended to decrease from higher latitudes down to lower latitudes. In areas of higher latutudes, T. ajelloi and M. cookei were isolated more frequently than in lower latitudes. M. gypseem was most frequent in Cheju City, and Chrysosporium species showed an even distribution, Among three areas under different conditions of moisture and shadedness(i.e., shaded wet, shaded dry, and sunny dry areas), frequency of isolation was highest in shaded dry areas(72.2%). T. ajelloi was the most frequent species in all the three areas, especially in shaded wet areas(53.1%). No M. gypsetcm was found in shaded dry areas. As regards distribution at various sites, roadsides and streamsides exhibited the highest frequency of isolation, and hills the lowest. Except for roadsides, T. ajelloi was the most frequent species at all sites, especially in forests. M. gypseum was frequent at sites beside streams M. cookei at streamsides, fields, and hills and Chrysosporim species in gardens, forests, and streets.

Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

Malignant germ cell tumors occur in children and young women in reproductive age, of all the germ cell malignancies, only pure dysgerminomas had a high cure rate prior to 1970. This was due to the exquisite radiosensitivity of these tumors. Multiple-agent chemotherapy has dramatically improved the pmgnosis of patients with malignant ovarian germ cell tumors. Clinicopathological analysis was performed on 21 cases of malignant germ cell tumors of the ovary, 9 cases at the department of Obstetrics & Gynecology, Kyung-pook National University Hospital, 4 cases, at the department of Obstetrics and Gynecology, Dong-guk University Kyungju Hospital and 8 cases, at the department of Obstetrics and Gynecology, Dae-gu Fatima Hospital during the period 10 years from July. 19S8 to June. 1997 The results were summarized as follows: 1. The mean age of the patients was 21.8 years old, ranging from 10 to 61 years old. 2. Main initial symptoms were abdominal distension(33.3%), abdominal mass palpation(33.3%), abdominal pain(28.6%), amenorrhea(4.8%) in order. 3. Histologically, the tumors were classified as immature teratoma(57.1%), dysgerminoma(19%), mixed germ cell tumor(9.5%), endodermal sinus tumor(9.5%), embryonal cell carcinoma(4.8%). 4, According to FIGO classification Stage I was the most prevalent(57.1%) at the time of diagnosis while Stage III was forward in 48.6%, Stage II in 9.5%, and no Stage IV, 5. The 5-year survival rate was 80.4% and three patients have died of malignancy and the other 18 patients live without disease from 11 to 102 months, with a median follow-up of 34.2 months. 6. Prognostic factors of malignant germ cell tumors in this study were the clinical stage, the presence of ascites and the residual tumor mass.

Malignant histiocytosis is a rare, usually fatal malignant neoplasm of reticuloendothelial systems. The disease is associated with fever, malaise, weight loss, hepatosplenomegaly, lymphadenopathy, pancytopenia, jaundice, and purpura. A 44-year-old female patient is described who had multiple, purple crusted nodules and plaques in the skin. In the laboratory study, pancytopenia was noted on the peripheral blood. In addition many atypical histiocytes were seen on the bone marrow aspiration. A lesional biopsy showed nodular infiltrations of atypical histiocytes in the dermis and some erythrophagocytosis was seen. Immunohistochemically, the histiocytes were weakly stained for lysozyme and α-l-antichymotrypsin, but were unstained for S-100 protein, cytokeratin, CEA(carcinoembryonic antigen), pan T/B marker CD30(ki-1), UCHL-1 LCA(leukocyte common antigen), and α-l-antitrypsin.

Candidiasis is the most common fungal infection complicating the course of patients with hematologic malignant neoplasms. Although widespread organ involvement is characteristic of disseminated candidiasis, reports of skin are rare. Reports describing typical clinical and histopathological finding of cutaneous lesions are very important since it may enable a diagnosis of disseminated candidiasis to be made and thus antifungal therapy can be initiated earlier. A 50-year-old housewife was admitted with a 5-month history of fatigue and easy bruising. She was diagnosed as ha.ving acute myelocytic leukemia and treatment was begun with daunorubicin and cytosin, arabinoside. Eight days after the start of chemotherapy, she developed a fever and generalized tender well demacated erythematous to purplish papulonodular eruption. A biopsy specimen from the skin lesion showed perivascular mononuclear cell infiltration and spore and pseudohypae v,rere found within the dermis and subcutis in PAS stain. Cultures of one skin biopsy specimen and one of four blood sarnples grew Candida tropicalis. The patient was treated with intravenous amphotericin B for disseminated candidiasis. On the tenth day of antifun gal therapy, she developed cardiopulmonary arrest and died.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.
