Leukaemic infiltration of gall bladder - unusual presentation of occult chronic lymphocytic leukaemia.

Extramedullary involvement in early stage chronic lymphocytic leukaemia (CLL) is rare. We report the first case of an incidental finding of gall bladder infiltration in a patient who underwent a cholecystectomy for gallstone pancreatitis with no preceding history of CLL. This case reiterates the importance of subjecting even routine cholecystectomy specimens for histopathology examination in the context of this unusual presentation.

Giant colonic mucocele following palliative surgery for metastatic adenocarcinoma.

We report an unusual case of a giant colonic mucocele following ileo-sigmoid bypass surgery in a patient with advanced adenocarcinoma of the splenic flexure. The formation of a giant colonic mucocele resulted from distal splenic flexure obstruction due to tumour relapse and proximal caecal obstruction due to peritoneal disease with subsequent accumulation of mucus in the closed loop.
