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...
