A smooth, well-defined intracavitary mass causing AUB.

- Leiomyoma
- Adenomyosis
- Ovarian neoplasm
- Carcinoma of uterus
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Read the hysteroscopic view: a single, smooth, rounded mass bulging into the cavity in a patient with abnormal bleeding.
Step 2: That morphology is classic for a submucous leiomyoma, the most frequent uterine tumour, made of myometrial smooth muscle and a well-known cause of AUB, pressure symptoms and subfertility.
Step 3: The competitors are excluded: adenomyosis thickens the wall diffusely with no discrete cavity mass, an ovarian tumour is extrauterine and invisible on hysteroscopy, and endometrial carcinoma looks irregular and friable rather than a smooth nodule.
\[\boxed{\text{Leiomyoma}}\]
