Diagnosis in short

Adenoid cystic/basal cell carcinoma of the prostate. H&E stain.
LM DDx adenoid cystic-like basal cell hyperplasia

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]
