Which classification system is used for AUB etiologies?

• A. FIGO
• B. PALM-COEIN
• C. WHO
• D. ACCP

Answer: (B)

Abnormal uterine bleeding (AUB) etiologies are organized with a standardized framework that helps guide diagnosis and management. The PALM-COEIN system, developed by FIGO, is the classification used for AUB causes. It splits etiologies into two broad groups: structural and non-structural. Structural causes (PALM) are tangible lesions seen in or on the uterus: polyps, adenomyosis, leiomyomas (fibroids), and malignancy or hyperplasia. Non-structural causes (COEIN) are conditions not tied to a discrete uterine lesion: coagulopathy, ovulatory dysfunction, endometrial causes (such as endometritis, endometrial hyperplasia or cancer), iatrogenic factors (like medications or devices), and those not yet classified. This system is specifically designed to categorize AUB causes, making it the standard reference for etiology-based evaluation. Other terms like FIGO refer to the organization, and WHO or ACCP pertain to different frameworks or contexts.
