Cytologic appearance of carcinosarcoma (malignant ameloblastoma and fibrosarcoma) of the maxilla. A case report.

The cytologic appearance of a carcinosarcoma (malignant ameloblastoma and fibrosarcoma) of the maxilla in a 63-year-old man is described. On his first admission the diagnosis of malignant ameloblastoma was made on biopsy. After five surgical excisions, radiotherapy and chemotherapy, the diagnosis was changed to carcinosarcoma because the stromal cells of the tumor had become malignant.

[Ipsilateral synchronous renal pelvic transitional cell carcinoma and renal cell carcinoma: a case report and review of the literature].

A case of ipsilateral transitional cell carcinoma of left renal pelvis and left-renal cell carcinoma is presented. A 75-year-old male consulted our hospital with the complaint of painless gross-hematuria which had persisted for four years. Excretory urography revealed left non-visualized kidney.

Familial occurrence of arteriovenous malformation of the brain.

Brain arteriovenous malformations are considered to originate from a congenital maldevelopment of the brain vessels. Although there have been occasional reports suggesting a familial incidence of these lesions, data for only 10 families have been accumulated in the literature. The authors report on six such cases in three families.

[A case of retroperitoneal tumor presenting with gross hematuria].

A case of retroperitoneal tumor presenting with gross hematuria is reported. A 62-year-old female consulted our clinic with the chief complaint of gross hematuria. On physical examination, a goose-egg sized tumor was palpable in the left flank region.

[Two cases of Graves' disease with anti-thyroid hormone autoantibodies: the effect of subtotal thyroidectomy on the titers of anti-thyroid hormone autoantibodies and anti-Tg antibodies].

We experienced two cases of Graves' disease associated with anti-thyroid hormone autoantibodies (Case 1: anti-T4, Case 2: anti-T3). Both cases underwent subtotal thyroidectomy, and titers of anti-thyroid hormone antibodies and anti-Tg antibodies were compared before and after operation. In case 1, titers of both anti-T4 and anti-Tg antibodies decreased after operation, whereas in Case 2, titers of both anti-T3 and anti-Tg were unchanged before and after operation.

[A case of testicular tumor presenting as acute scrotum].

A case of teratoma of the testis presenting as sudden spontaneous hemorrhage without previous injury is described. A 25-year-old male was admitted with right scrotal pain and swelling. Though acute epididymitis or testicular torsion could not be neglected on physical examination, tumor-like echogram was obtained.

[An autopsy revealing hepatocellular carcinoma with solitary metastatic gastric cancer].

This case concerns a 61-year-old man who had been determined as having rt-hypochondrialgia. The plasma AFP was found to have increased and an abdominal-CT revealed multiple low density areas in the liver. Endoscopic examination of the stomach revealed a Borrmann type III cancer and the specimens taken by punch biopsy demonstrated a tubular adenocarcinoma.

A case of silent thyroiditis associated with idiopathic thrombocytopenic purpura.

A 51-year-old woman had symptoms of thyrotoxicosis which disappeared spontaneously within two months. She was diagnosed as a case of silent thyroiditis on the basis of both the clinical course and the laboratory data such as low uptake of radioactive iodine and technesium. She also had petechiae in her arms which were diagnosed as an idiopathic thrombocytopenic purpura (I.

Clear cell carcinoma of the pancreas.

A rare autopsy case of clear cell carcinoma of the pancreas developing in a 71-year-old Japanese male is described. He complained of epigastralgia and back pain and was clinically diagnosed as having primary pancreatic cancer. After death due to disseminated metastasis and cachexy, autopsy revealed pancreatic clear cell carcinoma metastasizing to various organs including the lungs (lymphoangiosis carcinomatosa).
