Disseminated peritoneal Schistosoma japonicum: a case report and review of the pathological manifestations of the helminth

Salah Al-Waheeb et al. Ann Saudi Med. 2009 Mar-Apr.

Abstract

Schistosomiasis (also known as bilharzia, bilharziasis, bilharziosis or snail fever) is a human disease syndrome caused by infection from one of several species of parasitic trematodes of the genus Schistosoma. The three main species infecting humans are S haematobium, S japonicum, and S mansoni. S japonicum is most common in the far east, mostly in China and the Philippines. We present an unusual case of S japonicum in a 32-year-old Filipino woman who had schistosomal ova studding the peritoneal cavity and forming a mass in the right iliac fossa.
