睾丸原発の腫瘍は,最近報告症例がかなり多くなつたのだが,全泌尿性器腫瘍の3〜4%といわれており,その睾丸腫瘍の中でも,小児の腫瘍は全睾丸腫瘍の2〜3%であるので,稀な疾患と考えられている。われわれは最近1年間に小児の成熟奇形腫3例を経験したので報告すると共に,若干の文献的考察を加えてみた。
Case 1 is a 2 year-old boy who visited our clinic with the chief complaint of pigeon-egg sized indolent mass in the left scrotum since 9 months old. The mass, removed by high orchiectomy, was adult teratoma.
Case 2 is a 11 month-old boy with the chief complaint of pigeon-egg sized mass in the left scrotum.Left orchiectomy revealed adult teratoma without malignancy.
Case 3 is a 5 month-old boy with a mass in the left scrotum. Thumb-tip sized induration was palpat-ed in the left testicle. The histological findings of the removed tumor showed undifferentiated tissue such as neuroblast, but no malignancy was found.
