title: [Inflammatory-type malignant fibrohistiocytoma of the mesocolon associated with colonic parasitosis due to Trichocephalus].
abstract: A case of inflammatory malignant fibrous histiocytoma of the mesocolon is reported. The lesion presented as a right lower quadrant abdominal mass, located at the mesocolon, with obstructive symptoms and accompanied by a severe infestation by Trichuris trichiura. It had a benign histologic appearance and was considered initially as an inflammatory and necrotic process with severe tissue eosinophilia secondary to the severe parasitosis. The tumor relapsed 13 months later at the anastomotic site and the patient died. Diagnostic, prognostic and therapeutic aspects of this rare tumor are discussed.
