摘要:

A 49‐year‐old woman was admitted to the hospital with a palpable mass in the right hypochondrium. A laparotomy was performed under the clinical diagnosis of a solitary cyst of the liver. The cystic lesion of the liver was removed. Although the histological finding of the cyst wall showed a similarity to hepatocellular carcinoma of trabecular pattern, the tumor cells with uniform nuclei and little mitotic figure were positive for both argyrophil and argentaffin reaction. The pathological diagnosis was metastatic carcinoid tumor of the liver. There was no carcinoid syndrome nor the other clinical symptoms after the operation and various postoperative examinations could not reveal a primary site of the carcinoid tumor. The cystic lesion of the liver recurred ten months after the first operation and a second laparotomy was performed to reveal the primary site in the ileum: three submucosal tumors, 0.8, 0.7, and 0.3 cm. in diameter, two of them, however, extended into the muscle wall or subserosa and conclusively, the small lesion of the ileum metastasized into the liver as a large pseudocystic les

摘要:

A granular cell ameloblastoma occurring in the anterior mandible of a 49‐year‐old woman has been studied both histologically and ultrastructurally. Histologically the tumor in this case showed a mixed type of follicular, granular cell, and acanthomatous type of ameloblastoma. Many granular cells seemed to gather around the periphery of each tumor island. Electron‐microscopically the cytoplasmic granules were measured as approximately 0.6 μ in diameter, and were surrounded by limiting membrane. Most of these granules revealed high electron density and their contents showed various patterns — osmiophilic homogeneous, fingerprint, and small particles — and were identified as lysosomes. However, no enamel matrix precursor was identified in either lysosome or cytoplasm. All the granular cells showed regular nuclei and no degeneration. Though lysosomes might play a role of autophagy and of remodeling the cytoplasm, its presence seems to have an active function in tumor cells, as opposed to the aging or degeneratin

摘要:

A case of juvenile carcinoma of mammary gland in a 5 years old girl was reported. Only 32 cases of breast cancer in those under 19 years of age have been reported in Japan. The number of the cases in children under 10 years of age is extremely few totalling only 2 cases, including our case. The prognosis was different between the cases in Japan and those in foreign countries. This may be due to the difference in histology.

摘要:

Autopsy cases of myocarditis caused by Coxsackie viruses in two infants, aged 5 years and 10 months and 12 years, and two adults, aged 24 years and 45 years, were presented. Of the four cases, three revealed a rise in serum neutralization titer to Cox B4virus and one to both Cox B2and Cox B4viruses. Compared with the adult cases, the 2 infant cases showed less inflammatory response with relatively prominent hypertrophy in the heart. Both of the adult cases revealed intensive inflammatory reaction. Extensive inflammatory cell infiltration remained in one of the adult cases though the case survived about 4 years after manifestation of the infection, suggesting possible involvement of immunological factors.
