Cowper gland adenocarcinoma, also bulbourethral gland adenocarcinoma, is a cancer of the bulbourethral gland. It is very rare.
General
- Extremely rare - 9 reported cases in 2016.[1]
Microscopic
- Cribriform ‡ or trabecular or solid pattern.
- Cytologically bland morphology.
Note:
- ‡ May have morphology of adenoid cystic carcinoma and have MYB-NFIB fusion.[2][4]
DDx:

Features:[2]
- CK7 +ve.
- HWCK +ve.
- PSA -ve.
- PSAP -ve.
- SMA -ve.
- S-100 -ve.
Note: Benign Cowper's glands are described as PSA +ve, PSAP -ve, HMWK +ve.[5]
