“…The risk of malignant transformation of adenomas is correlated with age > 60 years; the presence of gallstones ≥ 3 cm for at least twenty years; a polyp size equal to or greater than 10 mm; patient origin from Asia, mainly India[ 25 ]; chronic infection by Salmonella [ 7 ] or Helicobacter pylori ( H. pylori )[ 26 ]; a body mass index greater than 30 kg/m 2 ; a diagnosis of schistosomiasis[ 27 ]; a diagnosis of primary sclerosing cholangitis; a polyp with a broad basis; and a thickened gallbladder wall greater than 4 mm and/or the presence of an abnormal gallbladder wall layer[ 7 , 15 , 18 , 28 ]. H. pylori may not be associated with gallbladder adenoma or gallstone formation[ 29 ].…”

Gallbladder adenomas are rare lesions (0.5%) associated with potential malignant transformation, particularly with gallbladder adenomas that are ≥ 1 cm in size. Early detection and management are crucial for preventing lethal carcinoma development. These polyps can often be distinguished from the more often nonneoplastic cholesterol pseudopolyps (5%-10%), which are benign. Ultrasonography is the first-line tool for initial diagnosis and follow-up when indicated. The question is whether cholecystectomy is always necessary for all adenomas. The management of gallbladder adenomas is determined according to the size of the tumor, the growth rate of the tumor, the patient’s symptoms and whether risk factors for malignancy are present. Adenomas ≥ 1 cm in size, an age > 50 years and a familial history of gallbladder carcinoma are indications for immediate laparoscopic cholecystectomy. Otherwise, ultrasound follow-up is indicated. For adenomas 6-9 mm in size, the absence of ≥ 2 mm growth at 6 months, one year, and two years, as well as an adenoma sized < 5 mm without existing risk factors indicates that no further surveillance is required. However, it would be preferable to individualize the management in doubtful cases. Novel interventional modalities for preserving the gallbladder need further evaluation, especially to determine the long-term outcomes.

Introduction: Schistosomiasis, caused by parasitic Schistosoma species, is a common neglected tropical disease prevalent in sub-Saharan Africa, including Sudan. While urinary tract infections are more frequent, intestinal schistosomiasis is rare. The disease presents with nonspecific symptoms often leading to misdiagnosis as inflammatory bowel disease (IBD). Case presentation: A 23-year-old male farmer from Gezira, Sudan, presenting with intermittent bloody diarrhea and mild left lower abdominal pain for six months. Despite multiple diagnoses and treatments for dysentery and IBD, his symptoms persisted. Colonoscopy revealed edematous mucosa with scattered whitish spots in the rectum, sigmoid, descending, and transverse colon, with normal findings in the ascending colon and cecum. Biopsies confirmed eosinophilic colitis with schistosomal egg shells. The patient was treated with praziquantel, leading to the resolution of symptoms within two weeks. Clinical discussion: Schistosomiasis, caused by Schistosoma mansoni, commonly manifests with myalgia, fever, and rash, alongside abdominal symptoms. Diarrhea, abdominal pain, constipation, and weight loss are common. Stool examination and serological tests aid in diagnosis, but colonoscopy can reveal characteristic findings, such as edematous mucosa and schistosomal nodules. Early diagnosis and treatment with praziquantel are essential to prevent complications and improve patient outcomes. Conclusion: This case emphasizes the importance of considering schistosomiasis in endemic areas when evaluating patients with colitis symptoms. Healthcare providers should maintain a high index of suspicion for this condition, especially in patients with nonspecific gastrointestinal symptoms and a history of travel to endemic areas. Early diagnosis and treatment are crucial to prevent complications and improve outcomes.
