Abstract
Desmoid tumors commonly occur in women, and it has been shown that the development and progression of desmoid tumors are associated with pregnancy and estrogen. We report the case of a woman found to have an abdominal desmoid tumor after the first month postpartum. A 32-year-old woman was referred to our hospital due to an enlarging left inguinal mass after delivery. General physical examination revealed a large, firm, fixed, and painful mass. Computed tomography (CT) and ultrasonography (UT) demonstrated an enhanced mass (8×5 cm in diameter) attached to the fascia of the left inferior rectus abdominis muscle. Malignancy could not be ruled out preoperatively. The tumor was arisen from the left rectus abdominis muscle, and was radically excised with the left rectus abdominis muscle and fascia. The histopathological and immunohistochemical examination demonstrated an estrogen receptor positive desmoid tumor. No recurrence was found at the 1-year follow-up. This report presents that the growth of desmoid tumors is associated with pregnancy and estrogen.
