title: Gall bladder lymphoid hyperplasia: masquerading as lymphoma.
abstract: Lymphoid hyperplasia of the gall bladder is an extremely rare condition that may be missed on associated radiological or clinical evaluation but is diagnosed on biopsy. We are reporting hereby, a case of reactive lymphoid hyperplasia masquerading as a lymphoma on histopathology. A 58-year-old male was referred to our hospital with complaints of pain abdomen infrequently since last one year. Ultrasonography revealed the presence of single calculus along with features of chronic cholecystitis. Laparoscopic cholecystectomy was performed and the gall bladder was sent for routine histopathological evaluation. On microscopic examination, there were sheets of cells, lymphoid in origin and numerous lymphoid follicles spread throughout the wall of the gall bladder. It was diagnosed as a case of reactive lymphoid hyperplasia with chronic cholecystitis on histopathology.
