Atypical polypoid adenomyoma
Atypical polypoid adenomyoma (APA) is a rare uncommon benign tumour of the uterus.[1]
Pathology[edit | edit source]
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.
