title: Gallbladder carcinoid masquerading as gallbladder carcinoma.
abstract: BACKGROUND
  Carcinoid of the gallbladder is rare. Since it often presents as a gallbladder mass it may be confused with gallbladder carcinoma.
  
  
  METHODS
  A 35-year-old lady presented with pain in the right upper abdomen, and was radiologically found to have a gallbladder mass. A provisional diagnosis of gallbladder carcinoma was made. Laparotomy revealed a 20 x 20 cm, exophytic, friable growth arising from the fundus of the gallbladder. It was excised with segment IVb and V of the liver and regional lymphadenectomy.
  
  
  RESULTS
  Histopathological examination revealed it was a neuroendocrine carcinoma, atypical carcinoid of the gallbladder.
  
  
  CONCLUSIONS
  Gallbladder carcinoid has a poor outcome, requires aggressive treatment, and should be considered as one of the rare but possible gallbladder lesions.
