Definition

A malignant neoplasm composed of prostatic basal cells (Ali and Epstein 2007; Ahuja et al. 2011; Iczkowski et al. 2003).

Clinical Features

  • Incidence

    Rare.

  • Age

    Mean patient age is 66–69 years.

  • Sex

    Male.

  • Site

    Transition zone of the prostate.

  • Treatment

    It requires ablative therapy with more aggressive behavior seen with the solid nested pattern.

  • Outcome

    These tumors predominantly show an indolent course with local infiltrative behavior. A small subset behaves aggressively with local recurrences and distant metastases. This group is characterized by large solid nests, more often with central necrosis, high Ki67%, and patchy staining with basal cell markers.

Microscopy

Most cases show varying proportions of: adenoid cystic/cribriform pattern with inspissated secretions and basaloid pattern with small solid nests with peripheral palisading of basal cells.

Other patterns included: basal cell hyperplasia-like, small tubules occasionally lined by a...
