Synonyms

Ectopic prostate tissue; Prostatic epithelial polyp

Definition

Polypoid, sessile, or papillary structure lined by prostate-type glands showing double layer of cells with cuboidal/columnar cells and flattened basal cells

Clinical Features

  • Incidence

    This represents an uncommon benign lesion. The histogenesis may be related with a metaplastic process or a defect of embryogenesis (Remick and Kuman 1984).

  • Age

    Age ranges between 13 and 84 years.

  • Sex

    Male patients

  • Site

    It projects into the prostatic urethra more often in or around the verumontanum. Uncommon cases have been reported in the bladder (Ishikawa et al. 1990).

  • Treatment

    Clinically prostatic-type polyps present with hematuria, hemospermia, and dysuria. The polyp may cause urethral structure (Sekine et al. 1993). It may be also an incidental finding. In rare instances, the diagnosis is made after a work-up for atypical urinary cells. The treatment is excision by cystoscopy and fulguration.

  • Outcome

    Recurrences are very rare.
