Desmoid Tumor: Rare Abdominal Wall Lump in a Multiparous Woman

ABSTRACT Background Desmoids are rare tumors. Abdominal wall desmoids are more common in women of reproductive age, especially postpartum women. Here we present a case of desmoid tumor in a 37-year-old multiparous woman, who came with the complaint of a slowly growing painless abdominal lump. Case report A 37-year-old multiparous female presented with the complaint of a gradually increasing, painless abdominal lump. On physical examination, a well-defined, firm, mobile mass was palpated in the suprapubic region. Ultrasound revealed a homogeneous hypoechoic lesion in the right anterolateral abdominal wall. Computed tomography (CT) of the abdomen showed a well-defined homogeneous mass in relation to the inferior aspect of right rectus abdominis muscle. These clinical and imaging features were highly suggestive of abdominal wall desmoid, which was confirmed on fine needle aspiration cytology and postoperative tumor histopathology. Discussion Desmoids are uncommon benign, locally aggressive fibrous lesions that have an insidious course. Conventionally, these are classified as abdominal desmoids (occurring in abdominal wall, mesentery, or retroperitoneum) and extra-abdominal desmoids (affecting shoulder girdle, trunk, lower extremities, etc.). The definitive diagnosis of desmoid has to be established on histopathology. Wide local excision remains the definitive treatment of abdominal wall desmoids. Radiation therapy, chemotherapy, and endocrine therapy are the other treatment options. How to cite this article Garg M, Prabhakar N, Prakash M, Dahiya D, Khandelwal N.
