title: Simple cysts of testis.
abstract: Three cases of benign intraparenchymal cysts of the testis are described. A nine-month-old infant and a forty-two-year-old man were seen with painless testicular enlargement and underwent orchiectomy and cyst excision, respectively. The third patient, a sixty-eight-year-old man, was asymptomatic with the cyst discovered following orchiectomy for prostatic carcinoma. In each case the cyst was multilocular and lined with a simple cuboidal epithelium. In 1 case special and immunohistochemical stains were performed. Review of the literature in conjunction with the cysts' staining characteristics are strongly supportive of its derivation from ectopic epithelium.
