巨大悪性褐色細胞腫の1例

A CASE OF GIANT MALIGNANT PHEOCHROMOCYTOMA

Ⅰ．緒言

　近年，諸検査法の発達により褐色細胞腫が少なからず発見され，その報告も次第に増加してきているが，この中で悪性のものは文献的に8〜10％とされている。著者らは最近，肺に転移を伴つた悪性褐色細胞腫を1例経験したので報告する。

An autopsy case of malignant pheochromocytoma of right adrenal in a 58 years old female is reported. The tumor was giant sized of 35 × 18 × 12cm with metastases to the lungs and periaortic lymph nodes. Clinically, no hypertension was noticed and chromaffin was noticed in only few cells histologically. The arrangements of the cells were very simillar to carcinoma of the adrenal cortex and differential diagnosis was possible by the presence of chromaffin cells.
