1.Ependymoma Containing Cartilage: A case report.
Korean Journal of Pathology 1990;24(1):77-81
The presence of cartilage in a glial tumor is exceptional. It frequently occurs in ependymoma of midline location in young child nuder 5 years of age. The mechanism of cartilage and bone formation in ependymoma is thought to be either metaplastic transformation from mesenchymal tissue or direct transformation from the neoplastic glial cells. A case of ependymoma containing cartilage and bone is reported. The patient is a 4 year-old girl, having calcified mass in the 4the ventricle and cerebellar vermis. The pathogenesis of cartilage formation in this ependymoma is more likely to support the mataplastic theory.

Korean Journal of Pathology 1989;23(3):311-321
The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.

Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.

5.A National Study on Biopsy-Confirmed Thyroid Diseases Among Koreans: An Analysis of 7758 Cases.
Journal of Korean Medical Science 1990;5(1):1-12
In order to determine the incidence and to understand recent trend of thyroid neoplasm and other thyroid diseases among Korean, a nation-wide collection of biopsy-confirmed and surgically removed thyroid lesions from 30 pathology laboratories of university and general hospitals was made over a 3-year-period from 1986 to 1988. These tumors and tumor-like lesions of the thyroid were classified according to the WHO classification. Results of this study were compared with those of the previous in Korea and other countries. Among the 7758 collected cases from 7449 patients, adenomatous goiter was the most common, comprising 2681 cases (34.6%), followed by follicular adenoma, 1868 cases (24.1%) and papillary carcinoma, 1474 cases (19%). Neoplastic condition comprised 48.8% (3786 cases). Of malignant tumors, papillary carcinoma was the most frequent accounting for 79.8%. The female to male ratio was 7.5:1 with female predominance. This female predominance was noted in all but two thyroid diseases. Medullary carcinoma showed equal distribution in both sexes, and two cases of malignant lymphoma developed in males. Thyroid diseases were common at the 3rd to 6th decades with peak incidence at the 4th decade. The right lobe of the thyroid was more frequently involved than the left lobe (1.6:1). The diagnoses were made largely on the surgically excised specimen (85.3%). Multiplicity of the lesions revealed single lesion in 64%, multiple and diffuse lesion in 36% of cases investigated. Average size of the lesion was in the range of 1-5 cm in diameter (62%).

Subcutaneous form of neuromuscular hamartoma is extremely rare and histologically different from the conventional neuromuscular hamartoma of the peripheral nerve or benign Triton tumor by an indistinct nodular growth with ill-defined margin and marked collagen interposition. It is usually not associated with a major nerve. We report a case of subcutaneous neuromuscular hamartoma developed in the forehead of 24-year-old man. The tumor showed proliferation of dense, hyalinized fibrous tissue, in which single or group of mature skeletal muscle fibers and nerve fibers were haphazardly intermixed. Recognition of abnormally arranged muscle and nerve fibers is important not to miss this lesion.

Korean Journal of Pathology 1992;26(2):171-174
Two cases of suprasellar papillary craniopharyngioma are presented. The tumors are exclusively composed of well-formed papillary squamous epithelium and show morphologic homogeneity. There is no palisading basal layer in squamous epithelium. Clinical and radiologic findings, exclusive occurrence in adult and lack of calcification, are much different from conventional craniopharyngioma. Differences between papillary craniopharyngiom and conventional craniopharyngioma are discussed.

This study, whose subjects are forty stroke patients in discharging who have been using FIM Western medical (Neurology, Neurosurgery, Rehabilitation Medicine) and Chinese herb medical base of D Hospital in Pusan from the first of May to the eleventh of July, has been made to evaluate the patients' functional conditions and analyze the factors affecting them. The result of study is as followings: FIM total score in discharging is avarage 85.83+/-28.96; the motor FIM score is 57.55+/-24.40 and the cognitive FIM score 29.95+/-6.99. The items recorded the highest score reveal the eating bowel management; the former is 5.68:t 1.73, the latter 5.33+/-2.23. The item recorded the lowest score reveal bathing and stairs, each 2.35+/-1.69 and 3.23+/-2.13. Analysis reveal it is in the case of age(p=.005) and durations of admission(p=.01) that there is significant difference of FIM score when stroke patients in discharging.

For the nonunion of humeral shaft, there have been many methods of treatment. We are aimed to analyse the causes of nonunion of humeral shaft fracture and present the direction of treatment. We reviewed total 21 cases which were diagnosed as delayed or nonunion of humeral shaft and analysed the causes. l. Initial method of treatment was surgical in 19 out of 21 cases. Among these 19 cases, 14 cases were operated with internal fixation with plate and screw. 2. The most common cause of nonunion was inadequate internal fixation in 26 cases(81%) in which were unstable fixation in 13 cases, choice of inadequate internal fixator in 11 cases, and failure of operative technique in 2 cases. Other causes were distraction between fracture fragments in 4 cases(13%) and open comminuted fracture in 2 cases. 3. Eighteen cases of established nonunion due to inadequate internal fixation were treated by rigid fixation with longer and broader plate and bone graft, and 1 case interlocking IM nailing, 1 case Ender nailing and 1 case bone graft only. 4. Union was obtained in all cases at least in 5 months. And there were no specific complications. In conclusion, surgeons should contemplate the operative indication and principles in primary treatment. In treatment of nonunion, surgeons should treat by more longer and broder internal fixator and additional bone graft.
