睾丸原発の細網肉腫について—臨床病理学的検討

PRIMARY RETICULUM CELL SARCOMA OF THE TESTIS WITH REFERENCE TO CLINICO-PATHOLOGIC FEATURES

はじめに

　睾丸の悪性腫瘍のうち，原発性の細網肉腫はまれなものとされており，Wescottの集計では，欧米の雑誌に発表されたもの約50例で^1），わが国においても現在まで約20例が報告されているにすぎない^2）。われわれは，当病理学教室で睾丸発生の腫瘍のうちで細網肉腫と診断された症例をえらんで，これらに対する臨床病理学的検討を加え，さらに通常のリンパ節原発の細網肉腫で死亡した剖検例のうち睾丸に浸潤を示した症例と比較してみた。それらについて興味ある結果を得たので報告したい。

The pathological diagnostic standard of reticulosarcoma of the testis has not yet been established, and the differential diagnosis with other disease is also difficult.

Four cases of reticulosarcoma, suspected to be originated from the testis were reported and some clinical pathological studies were done. Three cases among the 4 showed typical differentiated cells of the reticulosarcoma but the cells were small with scanty protoplasm in one case which was considered to be the atypical undifferentiated type.
