Which fibroid type is located on the serosal surface of the uterus?

• A. Subserosal leiomyoma
• B. Intramural leiomyoma
• C. Submucosal leiomyoma
• D. Pedunculated fibroid

Answer: (A)

Subserosal leiomyoma is the correct label because it describes a fibroid that sits on the outer surface of the uterus, just under the serosa. These tumors grow outward from the uterine wall toward the peritoneal cavity and may even become pedunculated, attaching by a stalk. In contrast, intramural fibroids are embedded within the myometrium, submucosal fibroids project into the uterine cavity, and pedunculated refers to the stalked shape rather than a specific location—often subserosal but not exclusively so. So when the fibroid is located on the serosal surface, subserosal is the precise description.
