Inflammatory pseudotumor of the abdomen: report of a case.

We report herein the case of a 38-year-old woman in whom a large tumor, 15 cm in diameter, was detected in the right lower quadrant of the abdomen. The tumor was removed and histological examination indicated that it was an inflammatory pseudotumor (IPT). IPT is not completely understood, but according to the few documented cases of IPT of the abdomen, its clinical behavior is benign and no recurrence has ever been reported. Thus, local resection is the most effective treatment.
