BACKGROUND: Schistosomiasis is one of the endemic parasitic diseases in many developing countries. Despite this, appendicitis secondary to schistosomiasis is an uncommon condition even in some endemic areas. Schistosomal appendicitis, an incidentally discovered appendicitis associated with schistosomiasis histological findings, affects young males predominantly. Timely diagnosis and treatment, including appendectomy and anti-helminthic therapy, are crucial.
METHODS: A 24-year-old Sudanese male patient presented with abdominal pain. Diagnosed with acute appendicitis, he underwent appendectomy, revealing appendix inflammation with Schistosoma ova in histopathology. Abdominal ultrasound detected no complications. Weakly positive Schistosoma serology was noted, but stool and urine analysis showed no infection evidence. Prescribed praziquantel, patient had 3-year post-op follow-up without complications.
CONCLUSIONS: This case report underscores the significance of including schistosomiasis in the differential diagnosis of appendicitis, particularly in regions where the disease is endemic. It underscores the necessity of histopathological evaluations for accurate diagnosis, emphasizing the potential implications for clinical practice in similar settings.

BACKGROUND: Moynihan\'s aphorism that \"gall stone is a tomb stone erected in the memory of the organism with in it\" is true even today. This case could be an example to reemphasise the forementioned axiom. We present here a case of Chronic Granulomatous Schistosomal cholecystitis which is an unusually rare cause of Cholecystitis and cholelithiasis, that too in a non-endemic area. The patient has never ever visited the known endemic zones of Schistosomiasis or Bilharziasis areas in India. In a way it could be the first case report of schistosomiasis in this area.
METHODS: A 59-year-old female patient presented to the Out-patient department of SMS&R, Sharda university, with right hypochondriac region pain and dyspepsia of six months duration. Investigation revealed Chronic Cholecystitis with Cholelithiasis. After a thorough workup the patient was taken up for Laparoscopic cholecystectomy, which was converted to open cholecystectomy due to adhesions and to prevent any iatrogenic injury to the biliary tree. Histopathological examination revealed Chronic Granulomatous Schistosomal Cholecystitis with Cholelithiasis. Patient did well in the post-operative period with anti-helminthic treatment.
CONCLUSIONS: Literature is still undecided whether the Schistosomal eggs deposition in the gallbladder can cause an episode of acute cholecystitis. However, a lithogenic outcome of schistosomiasis secondary to the induction of chronic granulomatous and fibrocalcific changes of the gallbladder and biliary ducts wall, seems probable.

Urinary schistosomiasis caused by Schistosoma haematobium worms is endemic to tropical regions where it is the most common cause of hematuria. However, the intermediate snail hosts, Bulinus truncatus, have been described in Portugal, Spain, Sardinia, and Corsica. S. haematobium has long remained exotic to Europe, however, an outbreak of urinary schistosomiasis in Corsica started in 2011 with B. truncatus as the primary intermediate host. We describe the case of a 12-year-old French boy presenting hematuria and dysuria who was diagnosed with urinary schistosomiasis. Urine examination confirmed the presence of viable parasitic ova. He also had a positive serology. Since there was no history of travel to a schistosomiasis endemic region, the probable area of contamination was identified as the south of Corsica where the family had spent their summer holidays 7 months earlier. Two other family members had a positive serology without ova excretion in urine. The patients were treated with praziquantel. In light of these recent locally acquired cases in France, schistosomiasis should be considered in the differential diagnosis of hematuria, especially in patients who have recently visited Corsica.
