Introduction:

Myofibroblastic tumors are benign tumors of mesenchymal origin, of uncertain etiology, and frequent in children and young people.

Objective:

To describe a new case of abdominal myofibroblastic tumor.

Clinical case:

The case is presented of a 20-year-old female patient with a health history and pain in the right abdomen. Contrasted abdominal tomography is performed, which shows an inhomogeneous hyperdense mass in the right flank. Surgical resection of the tumor was performed. The pathological study reported an inflammatory myofibroblastic tumor. Its prognosis is favorable because it is a benign entity that does not metastasize.

Conclusions:

Colon myofibroblastic tumors are infrequent, benign, and when diagnosed, they must be widely removed to avoid recurrence.
