Schistosomiasis of the appendix

Abstract

The clinicopathological features of schistosomiasis of the appendix are discussed, based on the clinical presentation, operative findings and morphological changes in the specimens of patients seen in Ibadan between 1980 and 1989. Schistosoma haematobium was implicated as the causal agent of a granulomatous inflammatory reaction with eosinophilia and fibrosis. Intramuscular oviposition was associated with frank acute appendicitis, and serosal involvement resulted in peritoneal adhesions, with ileoileal intussusception in one patient. The actual role of schistosomal infestation as a contributory factor in appendicitis is still open to debate, but the diagnosis must be entertained in patients in the tropics with features of acute appendicitis or recurrent abdominal pain.

Schistosomal peritonitis secondary to perforated appendicitis

“…6 Since then, there have been reports of acute schistosomal granulamotous appendicitis from endemic populations in South America and Africa, as well as from travelers and migrants returning from endemic areas. 3,[7][8][9][10][11][12] In a retrospective study from Nigeria, in 27 (2.3%) of more than 1,000 cases of appendicitis, schistosome eggs were seen in histological sections. 8 About 56% of these cases were caused by S. mansoni, 26% by S. haematobium, and 19% by S. mansoni/S.…”

“…14 In the case of schistosomiasis mansoni, intramuscular oviposition (submucosa) may cause an obstructive type of appendicitis with a greater risk of perforation. 3 Serosal involvement causes inflammation and the formation of adhesions. 3 Confirmation of schistosomal involvement of organs is usually made by histological diagnosis, due to the absence of pathognomonic clinical or operative findings.…”

“…3 Serosal involvement causes inflammation and the formation of adhesions. 3 Confirmation of schistosomal involvement of organs is usually made by histological diagnosis, due to the absence of pathognomonic clinical or operative findings. Thus, a clear communication between surgeons and pathologists for management of patients with suspected appendicitis is required for proper management.…”

“…4,5 The parasite is also known to affect multiple organs in the human host, including the appendix. 3 Here we report a rare case of acute schistosomal peritonitis secondary to perforated appendix.…”

Apendicitis granulomatosa sarcoidal: una infrecuente entidad clínico-patológica. Caso clínico

“…L a apendicitis granulomatosa es una entidad clínica poco frecuente (0,1-2%) considerándose dentro de los diagnósticos histopatológicos diferenciales a la enfermedad de Crohn, reacciones por cuerpo extraño, infecciones (bacterianas, micóticas y parasitarias) y la sarcoidosis [1][2][3][4][5][6][7][8][9] .…”
