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 20×20 cm, exophytic,friable growth arising from the fundus of the gallbladder.It was excised with segmentⅣb andⅤof the liver and regional lymphadenectomy. RESULT:Histopathological examination revealed it was a neuroendocrine carcinoma,atypical carcinoid of the gallbladder. CONCLUSION:Gallbladder carcinoid has a poor outcome, requires aggressive treatment,and should be considered as one of the rare but possible gallbladder lesions.
