* | *Tubular/cribriform architecture. | ||
* | *Intratubular eosinophilic material - '''key feature'''. | ||
**Classical: Arranged like the spokes of a wheel ("radial spikes"). | |||
**Atypical: Granules ~ 1-2 micrometers. | |||
*No mitotic activity. | |||
*Two cells populations (epithelial & myoepithelial) - like a well-behaved breast gland. | |||
Notes: | |||
*Usually small lesions: < 50 spherules per lesion, <100 micrometers. | |||
*May be multifocal. | |||
*+/-Calcifications - may prompt biopsy. | |||
