[Cyst of the prostatic utricle or remnant of the Mullerian duct?]. / Quiste del utrículo prostático o de restos de conducto de Muller?

The presence of a deep pelvic cyst posed the problem of diagnosing cysts originating from a prostatic utricle and those from mullerian vestiges. A case is presented of a male who came for consultation complaining of infertility. After complementary tests, the diagnosis of deep pelvic cyst was arrived at. It was considered that the cyst originated from vestiges of the mullerian duct based on the following clinical and pathological findings: - Appearance in the third decade of life. - No association with external genital anomalies. - Difficulty of surgical removal due to adherence to the prostate gland, seminal vesicles and posterior vesical wall.
