A Giant Sporadic Intra-abdominal Desmoid Tumor in a Male Patient: A Case Report

Abstract

Desmoid tumors (DTs) are rare locally aggressive benign soft tissue tumors with an estimated annual incidence of two to four new cases per million people. The giant intra-abdominal mass presents a diagnostic challenge that includes a broad differential diagnosis of gastrointestinal stromal tumor (GIST), fibrosarcoma, retroperitoneal fibrosis, and other malignancies from adjacent organs. We report a case of a 38-year-old male patient with a giant intra-abdominal mass. Magnetic resonance imaging (MRI) of the abdomen and pelvis indicated mucinous cystic neoplasm or gastrointestinal stromal tumor (GIST), but histopathology confirmed it to be a desmoid tumor. The patient was discharged, and on follow-up five months until now, there is no recurrence. This case highlighted the importance of including DT in the differential diagnosis of very large intra-abdominal masses.

A giant, rapidly growing intra‑abdominal desmoid tumor of mesenteric origin in an adolescent male: A case report and literature review

“…There are only a small number of case reports describing patients with large sporadic intra-abdominal mesentery-derived desmoid tumors ≥19 cm in diameter, with no family history of cancer and no operative or traumatic history (Table III) (26)(27)(28)(29)(30)(31). All patients in the aforementioned reports were male, with a mean age of 33 years old.…”

Contrast-enhanced ultrasonography combined with superb microvascular imaging for preoperative diagnosis of sporadic intra-abdominal desmoid-type fibromatosis: A case report

“…Intra-abdominal desmoid-type fibromatosis is usually diagnosed using abdominal computed tomography (CT) and/or abdominal magnetic resonance imaging (MRI) [ 6 , 7 ]. Transabdominal ultrasonography (US) and contrast-enhanced US are also useful for diagnosing intra-abdominal lesions [ [8] , [9] , [10] , [11] ].…”
