We report a case of extraskeletal osteosarcoma in view of rarity, and a brief review of the literature related to this type of tumor is presented. The patient was a 31-year-old Korean woman, who had noticed a bean-sized hard mass in the right thigh progressively enlarged to become egg-size during about 7 months, followed by pain and tenderness. There was neither recognizable previous lesion nor causable agent about the mass on history taking. Physical examination revealed another palpable mass on the inguinal area. The right thigh and inguinal masses were simply excised and histologically confirmed to be an extraskeletal osteosarcoma and metastatic one, respectively.

This study was undertaken to evaluate the significant diagnostic points of chronic alcoholic hepatitis (CALH) among clinicopathologic findings observed. The specimens used in this study were 20 cases of CALH and 28 cases of chronic active viral hepatitis (CAVH), which were diagnosed at our University Hospital during 9 years period from 1978 to 1987. In these cases, comparative analysis of age and sex distribution, major clinical manifestations, and laboratory and histopathologic findings was performed. The results obained were summarized as follows: Among 20 cases of CALH, the sex distribution was 15 in male and 15 in female with a ratio of 3:1. The range of age distribution was wide from third to seventh decade. There was no recognizable special point about the age and sex distribution of CALH, compared with cases of CAVH. Major clinical manifestations of CALH were hepatomegaly (85%), jaundice (75%) and abdominal pain (50%). Also there was no recognizable special point about the major clinical manifestations of CALH, compared with cases of CAVH. Abnormal values of major laboratory items in CALH were observed in activities of serum r-GTP (100%), SGOT (95%), SGPT (75%) and serum alkaline phosphatase (60%), and total serum bilirubin (60%). Compared with CAVH in major laboratory findings, the significant diagnostic items of CALH were the activities of serum r-GTP and alkaline phosphatase. The characteristic histopathologic findings of CALH, which were compared with CAVH and observed in liver parenchyma, were fatty change (100%), cytoplasmic ballooning and coagulation (100%), delicate fibrosis (85%), bile stagnation (35%), and Mallory bodies (20%), and that observed blurring of limiting plate (60%) in portal and periportal areas.

Fracture of the vertebral end plate in the lumbar spine has been reported as a rare lesion occurring in the adolescent period. It is characterized by variable degrees of sign and symtom related to the degree of block on myelogram and the level of end plate fracture. Trauma or strenuous sport activity seems to play an improtant role in the production of fracture of vertebral body in the adolescent period. We experienced three cases of fracture of lower lumbar vertebral end plate in teenaged patients, two males and one female. Two patients showed upper end plate fracture with severe neurologic deficit on the involved root level and a strong positive on straight leg raising test, and one patient showed lower end plate fracture with slight neurologic deficit. Two patients with upper end plate fracture were treated with partial laminectomy with removal of fracture fragment and one patient with lower end plate fracture was treated with bilateral laminectomy and posterolateral fusion. The method of treatment will depend upon the type of fracture and the degree of neurologic symptoms. We obtained satisfactory results with posterior decompressive laminectomy and removal of fracture fragment with or without fusion.

The Pleomorphic xanthoastrocytoma(PXA) is considered as a special subgroup of gliomas because of its distinctive characteristics: onset in young subject; predilection for the temopral or parietal lobe and a superficial location; frequent appearance as a yellow encapsulated mass with a grossly visible tumor-associated cyst; marked histological pleomorphism; little or no mitosis and no necrosis; presence of a rich reticulin network; and demonstrable GFAP in many of the fusiform and giant cells; most importantly, the relatively favorable prognosis despite plemorphism and bizzare giant cells in the microscopic picture. The objective of this report is to add one more case of pleomorphic xanthoastrocytoma to the medical literature.

This study was performed with the purpose of histochemical comparison of CEA and EMA localization between adenoma and well-differentiated adenocarcinoma of the stomach. The specimen was 12 lesions of adenoma and 15 foci of well-differentiated adenocarcinoma of the stomach. The markers in neoplastic tissue and neighbouring mucosa of the tumors were examined in paraffin sections using peroxidase-antiperoxidase method. The data obtained were evaluated statistically. The results were summarized as follows: 1) In 12 lesions of stomach adenoma, the positive reaction to CEA was seen in 3 lesions (20.0%), and to EMA in 10 lesions (83.3%). The positive rate of CEA in adenoma was lower than that of the neighbouring normal mucosa, but the positive rate of EMA was similar between the two. 2) In 15 foci of well-differentiated adenocarcinoma of the stomach, the positive reaction to CEA was seen in 13 foci (86.7%), and to EMA in 12 foci (80.0%). The positive rate of CEA in well-differentiated adenocarcinoma was higher than that of the neighbouring normal mucosa, while the positive rate of EMA was similar to each other. 3) Immunoreactivity to CEA in adenocarcinoma showed good positive correlation with the development of cuticular border of the neoplastic glands, while reactivity to EMA in adenocarcinoma was not related with the development of cuticular border. 4) The positive rate and intensity of CEA reaction in adenocarcinoma were higher than those in adenoma, but the positive rate and reactiveity of EMA were similar to those of adenoma. 5) The positive rate of CEA or EMA in the neighbouring mucosa of adenoma was not different compared with those in the neighbouring mucosa of adenocarcinoma. With the above results, it is concluded that adenoma and adenocarcinoma of the stomach may be different each other, biologically, and further more, it is presumable that adenoma may not be a premalignant lesions. It is considered that examination of CEA immunoreactivity may be helpful in differentiated of adenoma from well-differentiated adenocarcinoma, in most cases.

A case of pineoblastoma in a 28-year-old male is reported. A computerized tomography showed hydrocephalus and a mass in the pineal region. Histologically, the tumor is composed of regular, patternless aggregates of small round undifferentiated cells, resembling medulloblastoma-retinoblastoma group. Immunohistochemical reactivity of the neoplastic cells for neuron specific enolase and synaptophysin demonstrates neuronal differentiation. The patient underwent partial resection of the mass followed by radiotherapy. The patient had no cerebrospinal dissemination at 8 month follow-up. The pineoblastoma is a highly malignant neoplasm, one of the class of primitive neuroectodermnal tumors. The tumor is a very rare pineal parenchymal meoplasms, representing an incidence of less than 0.1% of intracranial tumors. This is the first case of pineoblastoma reported in Korea. In this report the divergent differentiation of the tumor is discussed, along with review of literatures.

The authors report a case of malignant teratoma in a 3-year-old girl who suffered from occipital headache and vomiting for about 2 months. The tumor occupied left cerebellopontine angle resulting in a moderate degree of hydorcephalus. Histologically, the tumor consisted mainly of neuroepithelial tissues showing varying degrees of differentiation, with areas of epidermis, mature fat tissue, connective tissue, gastrointestinal glands and smooth muscle bundles containing ganglions. Also noted are groups pf polygonal or spindle cells representing immature mesodermal tissue. In contrast to two malignant intracranial teratomas previously reported in Korean literatures, this case is characterized by the presence of predominent neuroepithelial components and by uncommon tumor location, the posterior fossa far from middle line of the body.
