Cavernous hemangioma of the testis: a case report and review of the literature

Abstract

A 73-year-old man consulted our hospital with a painless intra-scrotal mass in the left testis. Serum levels of human beta-chorionic gonadotropin and alpha-fetoprotein were normal. Scrotal ultrasonography demonstrated left testis with a heterogeneous texture. A diagnosis of probable testicular malignancy was made, and a left radical orchiectomy was performed. The histopathological diagnosis was testicular cavernous hemangioma. To our knowledge, only 19 cases of cavernous hemangioma of the testis have been reported in the literature so far. Although this is a rare tumor, it should be considered in the differential diagnosis of testicular tumor.

73歳, 男性, 左陰嚢胞無痛性腫大を自覚し来院。血清βHCG, AFPは正常であった。超音波所見では内部エコーの不均一な腫瘍を認めた。左精巣腫瘍を疑い, 左高位精巣摘除術を施行した。病理組織学的所見は精巣海綿状血管腫であった。精巣海綿状血管腫はこれまで19例の症例報告があるにとどまるが, 精巣腫瘍の鑑別診断として考慮に入れるべき疾患である。(著者抄録)
