Abstract

|
A 37 years old male patient had suffered from fibrous nasal polyp for more than 10 years even though careful medical treatment, and recently aggravated with severe nasal stiffness and pain. In the radiological observation the lesion was continuously extended into the ipsilateral maxillary sinus by poly cystic radiopacities gradually destroying the anterior wall of antrum. During the Caldwell-Luc operation a cystic fibrous granulomatous tissue was removed, and its microsections showed multicystic and tunnel-like spaces, of which lumens were usually round and filled with parts of parasitic worm exhibiting parasitic teguments and eggs. The granulomatous lesion showed relatively mild inflammatory reaction with the infiltration of eosinophilic PMNs. The histological features of tunnel-like penetration of parasitic worms, and their teguments and eggs were competent with the diagnosis of sparganosis. Especially, although the patient had no experience of raw foods such as frog or snake, he used to drink the untreated natural stream water obtained in the mountain area of Gangwon prefecture in Korea. Therefore, the present study demonstrated a rare lesion of antral spanganosis, and we suppose that the frequent incident of oral sparganosis in Gangwon prefecture is possibly related to the usage of untreated stream water in the mountain area of Gangwon prefecture in Korea.
