睾丸鞘膜腔にみられた嚢胞の3例 - とくに睾丸鞘膜より発生した嚢胞について -

Abstract

Three cases of cysts seen in the cavum tunica vaginalis testis were reported. The first case is a 5-year-old boy with solitary cyst arising from lamina parietal is of tunica vaginalis and histologically it revealed to be retention cyst of tunica vaginalis. The second case is a 56-year-old man with bilateral multiple cysts arising from lamina parietalis of tunica vaginalis. According to histological examination, the cyst was suggested to be retention cyst of the remnant of ductus epididymis. The last case is a 33-year-old man, whose cyst located between head of the epididymis and testis. The cyst seems spermatocele without sperm because of its location, but histological appearance is very resembling to rete testis. Then it also seems to be the same kind of "cyst of rete testis" as Campbell reported. All those cysts contain only serous liquid without sperm.
