On hysteroscopy, a submucosal fibroid is seen projecting entirely into the endometrial cavity with only a narrow stalk attaching it to the uterine wall. According to the FIGO classification of abnormal uterine bleeding, how should this fibroid be typed?
- A Type 1 (submucosal, less than 50% intramural)
- B Type 0 (pedunculated intracavitary) ✓
- C Type 2 (submucosal, 50% or more intramural)
- D Type 3 (contacts endometrium, entirely intramural)
Correct answer: B. Type 0 (pedunculated intracavitary)
Explanation
In the FIGO PALM-COEIN leiomyoma subclassification, Type 0 denotes a pedunculated submucosal fibroid lying wholly within the cavity without any intramural extension, exactly as described here. Type 1 has less than 50% intramural component, Type 2 has 50% or more intramural extension, and Type 3 abuts the endometrium while remaining entirely within the myometrium.
