- Testicular teratoma is characterized that has more than one germ cell layer in various stages of maturation and differentiation. The incidence of mature teratoma varies from 2 to 9% of all germinal testicular tumor. Only 3 cases of bilateral teratoma have been reported in the literature to date. The teratoma can occurs at all ages but is most common between the age of 15-35 year. It is relatively infrequently seen in childhood and infancy. In these age group, teratoma tends to be a benign. Recently, we experienced one case of bilateral testicular teratoma in 4 month-old infancy. We report a case of bilateral testicular teratoma found infancy with review of related literatures.

Abstract

- Malignant fibrous histiocytoma (MFH) of the spermatic cord represents an uncommon location for the most common soft tissue tumor in adults. MFH of the spermatic cord is extremely rare. No case report has been described in the Korean literature. We report a case of malignant fibrous histiocytoma, myxoid type, arising from left spermatic cord. A 77-year-old male presented with a painless left upper scrotal mass for 5 months. Simple mass excision was performed for a diagnosis. Grossly, the mass closely contacted with the left spermatic cord. Since a myxoid type of malignant fibrous histiocytoma was diagnosed from histopathological findings, left radical orchiectomy with high ligation of the spermatic cord was performed additionally. There were no evidence of local recurrence or metastasis at 6 months after surgery.

Abstract
PDF
- The transarterial embolization has been widely used to control bleeding. It has a variety of clinical utility; to reduce bleeding on the surgical field, to reduce the size of malignant tumor as a preopearative treatment, to treat arteriovenous malformation or arterial aneurysm as a curative method and to promote life quality of patient with diffuse or multiple hepatocellular carcinoma as a palliative treatment, etc. With the advance of modem technology, various embolic materials have been also developed. However, it has not been fully investigated of histopathologic changes of the embolized organs according to the embolic materials used. This study was undertaken to investigate the histopathologic changes of embolized renal artery in rabbit by various embolic materials, according to each embolic material and to time passed by after embolization. Of the 5 arteries embolized by ethylene vinyl alcohol copolymer (EVAL), one showed abscess formation in embolized kidney. The other 4 allowed to perform further pathologic study: within a week after embolization there was no any specific change in vessels, however, mnimal endothelial hypertrophy was observed following 2 weeks of embolization. Of the 8 renal arteries embolized by N-buthyl-2-cyanoacrylate (Histoacryl), 4 showed total occlusion of the main renal arteries as well as renal infarction, which reflects the strong adhesiveness of Histoacryl to vascular wall. The other 4 showed fibrinoid degeneration in vascular wall within a week. However, further change was not observed thereafter. In all the 5 renal arteries embolized by polyvinyl alcohol (Ivalon), there were infiltration of inflammatory cells along the vessel walls, within one week, which represents vasculitis. They showed some fibrosis with appearance of giant cells in the vessels two months after embolization, respectively. The results suggest that EVAL is useful for the embolization of hypervascular lesion with limited arteriovenous fistula, histoacryl for the curative treatment of the lesion with high blood flow or severe arteriovenous fistula, and Ivalan for palliative treatment of malignant tumor or arteriovenous malformation, respectively.

Abstract
PDF
- The idiopathic hypereosinophilic syndrome consists of peripheral blood eosinophilia of 1500/mm3 or more without a known cause, plus signs and symptoms of organ eosinophilia. The prognosis of HES without treatment is poor. However, about one third of the patients with this syndrome may respond to corticosteroid thrapy. Morever, the majority of the remainder may have a favorable response to hydroxyurea. We present here a case of hypereosinophilic syndrome without any identifiable causes, involving bone marrow, liver, lungs and cervical lymph node. We tried corticosteroid as a treatment but it showed no response. However the hydroxyurea showed good response.

Abstract
PDF
- A total of 53 gastric adenomas from endoscopically biopsied gastric mucosa were examined histopathologically. The average age at the time of endoscopic biopsy was 59 years, and gastric adenomas were found to be more frequent in the aged, particularly above the age of 50. The majority of adenomas occurred at the antrum. Concerning the shape of the adenomas, Yamada type II was more frequent (55%). All adenomas were accompanied by varying degree of intestinal metaplasia, and this findings suggest that gastric adenoma develops from intestinal metaplasia. In adenomas with severe atypia (grade III), endocrine cells (argyrophil and argentaffin cells) were markedly decreased or absent. Gastric adenocarcinomas coexistent with adenoma were seen in 5 (9.4%) out of 53 cases, and were more frequent in male than female patients (sex ratio, 4:1) and the average age was 61.4 years. It is suggested that there is a necessity of thorough follow-up study for definitive correlation between gastric adenoma and adenocarcinoma.

Abstract

- Supraclavicular lymph nodes are unique in that they can attract metastases from almost anywhere in the body and most common sites of metastasis from an unknown primary source. 125 cases which had been diagnosed as metastatic supraclavicular lymph node during the period between May 1983 and August 1991, were analyzed pathologically, and following distinctive characteristics could be outlined: 1) The most frequent sites of metastasis from primary lesions are lung (43%), stomach (23%), lymphoreticular (6%), biliary (5%), esophagus (2%), and pancreas (2%). 2) Histologic examination of metastatic supraclavicular lymph node revealed adenocarcinoma (57%), squamous cell carcinoma (12%), undifferentiated carcinoma (9%), small cell carcinoma (7%), malignant lymphoma (6%), malignant melanoma (1%) and undetermined carcinoma (8%). 3) In cases that histologic types were squamous cell carcinoma, undifferentiated carcinoma, small cell carcinoma and undetermined carcinoma, the most frequent primary site was lung.

Abstract
PDF
- The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC (80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported data were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers (SNOMED code micro glossary), and certain disease entities on very short duration.

Abstract

- Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis. Their radiologic appearance is relatively distinct and well defined. Recently we experienced 3 cases of sclerosing hemangioma of the lung in 54, 52, 51 years old women. The light microscopic findings are similar to the features reported by Liebow and Hubbell (1956).
