Schistosomiasis Combined with Colorectal Carcinoma Diagnosed Based on Endoscopic Findings and Clinicopathological Characteristics: A Report on 32 Cases

The chronic enteropathogenic disease schistosomiasis

“…19 Polyposis from intestinal schistosomiasis does not appear to be related with colorectal carcinoma, 20,21 but a recent study has shown that a history of colonic schistosomiasis japonica is a probable independent risk factor for the development of colorectal neoplasias. 22 Appendiceal schistosomiasis was first documented in 1909, and the most frequent species associated with this condition are S. haematobium and S. mansoni. In one case report, schistosomiasis haematobia presented as acute appendicitis in a 26-year-old Israeli male who developed symptoms 2 years after visiting Africa; tissue sections showed extensive inflammatory areas and fibrosed granulomas.…”

Prognostic Analysis of Schistosomal Rectal Cancer

“…Xu et al reported an epidemiological study about schistosoma japonicum and colorectal cancer in China (Xu et al, 1984). Liu et al described clinicopathological characteristics of colonic schistosomiasis based on endoscopic findings (Liu et al, 2013). This study reported the poor prognosis of patients with SRC in current treatment.…”

“…Liu et al described clinicopathological characteristics of colonic schistosomiasis based on endoscopic findings (Liu et al, 2013). This study concluded that the prognosis of patients with SRC was poorer than NSRC.…”

“…Abe and co-workers reported a patient with a sessile polyp in the rectum, further histological evaluation revealed a hyperplastic polyp and calcified Schistosoma eggs in the submucosa (Abe et al, 2006). Liu et al reported one mucinous adenocarcinoma caused by colonic schistosomiasis (Liu et al, 2013).…”

Schistosomiasis Manifesting as a Rectum Polyp in Nigeria

“…Our case did not have this problem. Another series of 32 cases from China (10) concluded that "Chronic schistosomiasis infestation has a probable etiological role in promoting genesis of colorectal neoplasm." Fortunately, the present patient reported promptly in accordance with the prevailing community health education standards (11).…”
