title: Tumoral form of ascariasis: report of a case.
abstract: The authors report a case of a tumoral form of ascariasis in a 7-year-old boy, simulating a benign neoplasm. Microscopic examination revealed a marked granulomatous inflammatory reaction associated with dense fibroblastic proliferation and abscess formation around viable, embryonated Ascaris lumbricoides eggs. Pathogenesis of this rare clinical form of ascariasis is discussed.
