Abstract
Desmoid tumors are uncommon soft tissue neoplasms that do not metastasize but are locally aggressive, often causing recurrence due to their infiltrative nature. This report discusses a case involving a symptomatic desmoid tumor in the right upper abdomen of a 23-year-old female patient. The diagnosis was established through clinical examination, ultrasonography, and computed tomography. A complete resection with a 2 cm margin followed by mesh placement for parietal reconstruction was carried out. Histopathological analysis confirmed the diagnosis of desmoid tumor. The patient was discharged on the fifth postoperative day and is recovering well. The "wait and watch" approach is suitable for asymptomatic patients, while surgical and systemic therapies are recommended for symptomatic individuals. Complete surgical excision with sufficient safety margins followed by parietal reconstruction using prosthetic reinforcement is advised when necessary.
