title: Ectopic prostatic tissue in the uterine cervix: a report of four cases and review of ectopic prostatic tissue.
abstract: We report four examples of prostatic tissue occurring in the uterine cervix of patients aged 22, 25, 31, and 77 years. Three were incidental findings in loop excisions (two patients) and cone biopsy (one patient) of the cervix for high-grade squamous dysplasia. One presented as a cervical mass, clinically suspected to represent a fibroid. The prostatic tissue consisted of ducts and acini, some of which had papillary or cribriform patterns. Squamous metaplasia was prominent in all cases. No Wolffian duct tissue was present. The glandular epithelium in all cases was positive for prostatic acid phosphatase and prostate-specific antigen. High molecular weight keratin, performed in two cases, highlighted basal cells in a manner similar to the normal prostate. These unusual cases, only one of which is documented previously, further complicate the often-challenging area of interpretation of benign glandular lesions of the cervix. The unusual phenomenon of ectopic prostate tissue in general is reviewed.
