Mucinous fibroplasia, also collagenous micronodules, is a finding seen in the prostate gland that is considered pathognomonic for prostate carcinoma by many genitourinary pathologists.[1][2]

- Thought to arise from intraglandular mucin.[citation needed]
Microscopic
Features:
- Small collegneous-like nodules within (malignant) prostatic glands.
