Adenoid cystic/basal cell carcinoma of the prostate, abbreviated ACBCC, is a rare from of prostate cancer that resembles adenoid cystic carcinoma and basal cell carcinoma.
It is also known as adenoid cystic carcinoma of the prostate.[1]
General
- Rare.
- Typically indolent - may be aggressive.[2]
Microscopic
Features:
- Adenoid cystic carcinoma-like and basal cell adenoma-like:
- Nests of cells that have round spaces filled by whispy blue mucin.
- Dense collagenous stroma.
DDx:
- Adenoid cystic-like basal cell hyperplasia[1] - BCL2 -ve, Ki-67 low.[3]
