[Diagnosis of superficial-type early carcinoma of the gallbladder by endoscopic ultrasonography--comparison with ultrasonography].

The detectability of superficial-type carcinoma of the gallbladder by ultrasonography (US) and endoscopic ultrasonography (EUS) were investigated. Eight patients with such carcinoma of the gallbladder were reviewed. They had undergone both US and EUS previous to surgery. The tumor was detected in 3 patients by US, 2 patients with IIa + IIb-type carcinoma and 1 patient with IIa-type carcinoma. Those lesions were visualized as localized thickening of the gallbladder wall or as broad-based tumor. In 2 patients, lesions were not initially detected by US, but were shown by US after the examination by EUS. The tumor was detected by EUS also in 1 case of IIb + IIa-type carcinoma besides those 3 patients mentioned above. All four of these lesions were visualized as broad-based tumor by EUS. It was difficult to detect pure IIb-type or small IIa-type carcinoma even by EUS. In patients with concomitant acute cholecystitis or gallbladder stone, it was difficult to evaluate the abnormal findings of the gallbladder wall.

[Case of three peculiar tumors of gastric epithelioid leiomyosarcoma, retroperitoneal paraganglioma and pulmonary chondroma].

A 27-year-old woman with an unusual combination of three independent tumors, gastric epithelioid leiomyosarcoma, retroperitoneal paraganglioma and pulmonary chondroma is reported. There are 15 similar cases collected by Carney (1979) from the literature; ours is the first Japanese case. Patients with this tumor triad tend to be young females, all were of blood group A. The prognosis of these patients is generally good without associated systemic hypertension. Our patient is well 18 months after surgical removal of the three tumors.
