[A case of recurrent cyst of Müllerian duct].

A case of recurrent cyst of Müllerian duct is reported. The patient had complained of dysuria and underwent resection of Müllerian duct cyst in May, 1977. Five years later (in July, 1982) at 50 years old, he again visited our clinic with the complaint of urinary retention and perineal mass formation. Recurrent multilocular cyst of Müllerian duct was diagnosed by CT and transrectal ultrasonotomography. Transabdominal extirpation of Müllerian duct cyst, combined with perineal approach, was performed under general anesthesia. The cyst was multilobular, 165 g in weight and 17 X 6.5 X 4 cm in size. Transparent yellow fluid of the cyst was about 2,000 ml in volume. Histologically it was fibroadenomatous cyst. The differential diagnosis and surgical treatment of Müllerian duct cyst is discussed.
