後腹膜腫瘍の1例 --リンパ球浸潤を伴った血管腫--

Abstract

A case of retroperitoneal tumor was reported. This 38-year-old man, who has had dull pain in the left flank for about 5 years, was noticed to have a left abdominal mass by a physician. He was referred to our clinic on the 7th of March 1966. The patient had no other complaints except for the abdominal mass. The tumor measured 12×10×5 cm in size and represented a liquid content by way of abdominal tomography, aortography and ultrasonic diagnosis preoperatively. The tumor was surgically removed on the 8th of April 1966, and details about the operation and the histopathology in reference to morphogenesis were described and discussed. It was, then, concluded as "benign hemangioma assosiated with marked lymphocytic infiltration" which occurred in the perirenal fatty tissue. The patient has been well over 3 years after the surgery.
