The PALM-COEIN classification system (FIGO 2011, revised 2018) for abnormal uterine bleeding (AUB) classifies 'coagulopathy' as:
- A P — polyp
- B C — coagulopathy (structural)
- C C — coagulopathy (non-structural) ✓
- D E — endometrial
Correct answer: C. C — coagulopathy (non-structural)
Explanation
The PALM-COEIN framework distinguishes structural (PALM: Polyp, Adenomyosis, Leiomyoma, Malignancy/hyperplasia) from non-structural (COEIN: Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic, Not yet classified) causes of AUB. Coagulopathy (C) is a non-structural cause — examples include von Willebrand disease, hemophilia carrier state, thrombocytopenia. This distinction matters clinically because structural causes generally require imaging or hysteroscopy, while non-structural causes may be addressed medically.
