A 50-year-old Japanese man with enlargement of the right scrotum was presented to our hospital. Preoperative examination confirmed a multilocular cyst with septa attached to the testis. Radical orchiectomy was performed. Pathological examination revealed closely-located two cysts; larger one was infected hydrocele testis, and smaller one was epithelial cyst, which were immunohistochemically positive widely for estrogen receptor (ER) and partly for progesterone receptor (PR). We concluded that the smaller cyst was serous cystadenoma of the epididymis.
