Explanation

The FIGO PALM-COEIN classification: PALM = structural causes (Polyp, Adenomyosis, Leiomyoma, Malignancy/hyperplasia); COEIN = non-structural causes (Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic, Not-yet-classified). Coagulopathy (including von Willebrand disease, platelet disorders, anticoagulant use) is a COEIN non-structural cause. Endometrial polyp and adenomyosis are structural PALM causes.
