Atypical polypoid adenomyoma, abbreviated APA, is a rare uncommon benign tumour of the uterus.[1]

Pathology[edit]

APAs are characterized by glands with abnormal shapes that: (1) often have squamous metaplasia, and (2) are surrounded by benign smooth muscle.[1] Nuclear atypia, if present, is mild.

The microscopic differential diagnosis includes endometrial carcinoma and endocervical adenocarcinoma.
