Objectives: We present a case of giant cyst of the rete-testis.
Methods/results: 85 year-old patient on follow -up for prostate cancer with maximum androgen blockade (MAB) treatment consults for a left hemiscrotum increase in size over a 2-month period. We performed bilateral orchiectomy confirming the histopathological diagnosis of cystic dilatation of the rete-testis sized 11 x 11 x 9 cm.
Conclusions: This case of cystic degeneration of the rete-testis, with a size out of common (11 x 11 x 9 cm versus medium size in the literature: 3 x 3 x 3 cm), could be related with an androgen-estrogen misbalance caused by a MAB in a prostate cancer context.
