title: Mature cystic teratoma of the ovary with male accessory sexual glands including seminal vesicles, prostatic tissue, and bulbo-urethral glands: a case report.
abstract: We present an extremely rare case of a benign cystic ovarian teratoma with structures of male accessory sexual glands. The patient was a 30-year-old woman. A unilocular cystic tumor, measuring 5 cm in the largest diameter, was found in her right ovary and was removed. The teratoma contained epidermis, skin appendages, respiratory and intestinal epithelia, cartilage, muscle, and nervous and connective tissue. In addition to these histologically mature tissues, there were nodules with prostatic acini, prostate duct-like structures strongly positive for prostate-specific antigen and acid prostatic phosphatase, structures resembling Cowper's glands, and seminal vesicles surrounded by fibromuscular stroma. To our knowledge, this is the first case in the English literature describing seminal vesicles associated with prostatic tissue and bulbo-urethral glands in a mature ovarian teratoma.
