Since Lebert stated, in 1851, that fibroblastic and sarcomatous tumors of the intracranial cavity had different survival times, many neuropathologists tried to set up histopathological grading system predicting the prognosis of the tumor of the nervous system. Especially, the histological assessment of the aggressiveness of meningiomas has not always been useful in conforming the biological characteristics of these tumors, and the definition of malignancy is still subject to controversy. However, metastases from meningioma to remote sites have always been considered rarities. The authors experienced a case of metastatic meningioma, hemangiopericytic type, with a history of recurrence. A forty years old male patient received a craniotomy to remove a mass in right parasagittal region, in June 1981. He had suffered from Jacksonian type of seizure started from left foot throuth leg, thigh, and arm to face. During operation, a well defined mass was noted in left parasagittal region with cleavage plane. The tumor was completely removed with cauterization of invasion site. In microscopic examination, the mass had typical findings of hemangiopericytic type of meningioma. In September 1987, he received a repeat operation to remove a recurred tumor mass in vertex, at age of forty-six. The removed tumor revealed same histologic features as those seen in primary tumor. In January 1990, at age of forty-nine, he noted pain and tenderness on the right iliac crest and the left iliac tuberosity, Plain pelvis AP x-ray ad Pelvis CT scan revealed osteolytic expansile mass lesions involving both iliac bones, the body of second sacral vertebra, and the right superior ramus of the pelvic bone. An open biopsy of the iliac bone was performed. The microscopic findings of the bone lesion were same as reccruent lesion of the brain.

Neurosarcoidosis without systemic manifestation is vary unusual condition. Solitary lesion in the spinal dura is exceptional. The diagnosis of the neurosarcoidosis is very difficult, because the efficacy of Kveim test is low in neurosarcoidosis. The histologic examination is considered as confirmative diagnostic tool. The authors reported a case of neurosarcoidosis involving the dura of the cervical spine, in a fifty-nine year old female who had suffered from mid-back pain for six months and paraparesis for two weeks. There was a dumbbell shaped mass in the D4-5 dura. It showed tan gray color with rubbery consistency. With histological examination, it revealed diffuse non-caseating granuloma. Occasionally asteroid bodies were observed within the cytoplasm of the multinucleated giant cells. After operation, she was treated with steroid, and she has been well about nine month period.

Burkitt's lymphoma with a frankly leukemic picture is an extremely rare condition, and usually has a very acute course with a poor prognosis. The authors experienced two cases of Burkitt's lymphoma developed acute leukemia. The first case was 8 years-old boy who had rapidly growing large abdominal mass, which revealed typical Burkitt's lymphoma with characteristic "starrysky" pattern. The second case was 20 year old male who had not definite tumor mass. Their peripheral blood and bone marrow aspiration revealed acute leukemia with multiple vacuolated lymphoblast of Burkitt's type. We report these cases with brief review of literatures.

The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.

The rhabdomyosarcoma of the prostate is very rarely encountered in the western literature, and only a few reports have been published in Korea. The authours recently experienced two cases of rhabdomyosarcomas of the prostate in 35-year-old and 51-year-old males who had suffered from gross hematuria and difficulty of urination. Microscopic studies showed embryonal type of rhabdomyosarcoma in two cases. The clinical and pathological features of the distinctive prostatic rhabdomyosarcoma are described, and a brief review of the literature is made.

The clinical and pathological features of a distinctive female adnexal tumor of probable Wolffian origin (FATWO) are presented. As fat as our knowledge is concerned, no report on the FATWO has been published in Korea. In April, 1986, we experienced a case of FATWO that arose within the leaf of the right broad ligament in a 68 years old female. Clinical data and histopathological findings of the case were discussed and a brief review of the literature on this entity was made.

The clinical and pathological features of trichoadenoma are presented. Trichoadenoma is very rare, and as far as we know, no report on the trichoadenoma has been published in korea literature. We experienced a case of trichoadenoma occured in a 29 year-old male, who had a 0.9x0.7x0.4cm sized and slowly growing mass in the right buttock. The histopathological findings and histogenesis of trichoadenoma were discussed and a brief review of the literature was made.

Sebaceous epithelioma is a relatively rare tumor, mostly occuring in the face or scalp. The histogenesis and clinical and pathological features of sebaceous epithelioma have not been clearly defined, and a few other diagnostic terms have been used so far instead of sebaceous epithelioma. Two cases of sebacous epitheliomas were presented. No recurrence or metastasis was observed in our cases, so sebaceous epithelioma is considered to be a benign tumor. A brief review of the literature, concerned about the biological behavior, histogenesis and pathological findings of the sebaceous epithelioma, was made.
