Prostatic Tissue in Ovarian Mature Cystic Teratoma: A case report.: Seung Mo Hong, Mi Sun Choe, Eun Mee Han, Hun Kyung Lee, Jae Y Ro; Korean J Pathol. 1999;33(7):525-528.

Abstract PDF: Ovarian mature cystic teratoma containing benign prostatic tissue is rare and only 11 cases have been reported in the literature to date. We report a case of mature cystic teratoma of the ovary containing prostatic tissue. A 23-year-old female patient came to our hospital complaining of irregular menstruation for 3 months. Her menarche had occurred when she was 13 years old. The patient showed no evidence of virilization nor of endocrinopathy. A goose-egg-sized mass was palpable in the left lower abdomen on physical examination. Ultrasonography revealed a cystic ovarian mass with internal echogenecity. Microscopic finding was consistent with that of usual mature cystic teratoma except for a 1.5 cm focus of prostatic and bladder tissues. Prostatic tissue demonstrated strong immunoreactivity for prostatic specific antigen (PSA), prostatic alkaline phosphatase (PAP) and cytokeratin 7. Basal cells of the prostate glands were positive for high molecular weight cytokeratin (34betaE12). Although ovarian mature cystic teratoma containing prostatic tissue has been reported as a rare occurrence, a careful examination with immunohistochemical staining may increase the detection of prostatic tissue in mature cystic teratoma of the ovary.

Heterotopic Prostatic Tissue with Cystic Change in Retrovesical Space: A case report.: Hyun Jin Son, Myoung Jae Kang, Dong Geun Lee; Korean J Pathol. 2000;34(1):93-95.

Abstract PDF: Heterotopic prostatic tissue has been reported in a variety of sites within and outside the urinary tract. Extra-urethral ectopic prostatic tissue is a distinct entity and may be more common than previously thought. We report a case of heterotopic prostatic tissue in 71-year-old man. Pelvic CT scan showed a well circumscribed cystic mass in the retrovesical space. Grossly, the tumor was 7.5 7.0 2.8 cm and revealed an ovoid unilocular cyst containing grayish amorphous granular materials. The prostatic origin of the tissue was confirmed by immunohistochemical staining for prostate specific antigen.
