Mesenteric desmoid tumor involving the small intestine: diagnostic and therapeutic challenges

Desmoid tumors are rare, fibroblastic neoplasms of intermediate malignancy characterized by aggressive local invasion and a high recurrence rate, despite lacking metastatic potential. We present the case of a 43-year-old man with no prior medical history who developed a symptomatic intraperitoneal desmoid tumor. Imaging revealed a well-defined mass without evidence of metastasis. Surgical management was challenging due to the tumor's infiltrative behavior. This case underscores the diagnostic and therapeutic complexities of desmoid tumors and highlights the need for early detection, meticulous surgical planning, and rigorous postoperative surveillance.
