Rationale:
Intraabdominal fibromatosis is a rare benign tumor that often affects the mesentery or retroperitoneum, and can infiltrate adjacent organs. However, it is rare for fibromatosis to arise from the small intestinal wall.
Patient Concerns:
A 27-year-old female with a tangible abdominal tumor is described.
Diagnoses:
The computed tomography (CT) scan revealed a 7.5 cm, small intestine-associated tumor in the right abdomen.
Interventions:
The patient received tumor resection and intestinal anastomosis.
Outcomes:
Further pathological examination confirmed the tumor as a duodenal fibromatosis that infiltrated the intestinal wall. To the best of our knowledge, this is the first report of a duodenum-derived fibromatosis that invaded the muscular layer of the intestine.
Lessons:
Our study demonstrated that an unexplained abdominal mass should be noteworthy and properly treated.
