Pseudohyperplastic prostatic adenocarcinoma, also pseudohyperplastic adenocarcinoma is an uncommon type of prostate carcinoma that may mimic benign prostate.
General
- Uncommon <3% of cases in one series.[1]
- May mimic benign prostate.[1]
- Can be found with or without conventional prostatic adenocarcinoma (acinar type).
Microscopic
- Medium to large glands with an atypical morphology - key low power feature:
- Papillary or pseudopapillary infoldings, luminal undulations, branching or cystic dilatation.
- Nuclear features of conventional prostate cancer (nucleoli, nuclear enlargement).
Notes:
- Often associated with conventional (acinar) prostate adenocarcinoma.
- Pale abundant cytoplasm - similar to normal prostate.
DDx:
- Foamy gland carcinoma - often lack prominent nucleoli, smaller glands.
- Benign prostatic glands - esp. at low power.
