女性型乳房を呈した睾丸腫瘍（胎児性癌＋絨毛上皮癌）の1例

TESTICULAR TUMOR ASSOCIATED WITH GYNECOMASTIA : A CASE REPORT

Ⅰ．緒言

　睾丸悪性腫瘍症例でその経過中に女性型乳房の発達を合併してくる症例は比較的まれでその5〜10％にこれを見るに過ぎなく，本邦においては志田ら^1）の報告をはじめとして10数例^2）〜10）の報告に接しうるに過ぎないようである。われわれは，最近本腫瘍症例で除睾術後9ヵ月目に両側女性型乳房の出現を見，相前後して身体諸臓器に広範な転移をきたし死亡した症例を経験した。本症例につき臨床経過および剖検所見の詳細を報告するとともに，睾丸腫瘍における女性型乳房出現の頻度，組織型との関係，さらに内分泌異常との関係などをめぐつて若干の文献的考察を加えたい。

On March 22, 1965, T.N., a male, aged 21, was first seen at the District Hospital 17 days after he had noticed an enlargement of the left testicle. Physical examination disclosed a hard, smooth, fist-sized intra-scrotal mass on the left side. There were no other pertinent physical findings. Pregnancy test was positive (Sero-test). A left orchiectomy was performed, with a pathological diagnosis of emryonal carcinoma with foci of choriocarcinoma. The pregnancy test became negative 26 days after operation, and there were neither signs of recurrence nor metastasis. He was discharged with restoration of health on May 22.
