Mesenteric fibromatosis, also known as mesenteric desmoids, is part of the clinical-pathologic spectrum of deep fibromatosis, which encompasses a group of benign fibro-proliferative processes that are locally aggressive and have the capacity to infiltrate or recur without metastasis.
CASE REPORT: Case of a 45-year-old man, with a history of hypertension and lung fibrosis, presenting for a left abdominal mass, which was found incidentally during his lung fibrosis imaging. He complained of constipation due to pressure upon his bowel leading to difficulty in defecation.
CONCLUSIONS: Although there are many overlapping criteria between gastrointestinal stromal tumors and mesenteric fibromatosis, making it difficult to discriminate between the two, there are differences that are unique to mesenteric fibromatosis that should be noticed during the diagnosis. In this case, mesenteric fibromatosis was unusual as it is not associated with Gardner’s syndrome, desmoid tumors, nor familial adenomatous polyposis, but was an incidental finding.
