title: Small cell carcinoma of the appendix.
abstract: BACKGROUND
  An extrapulmonary small cell carcinoma is a rare condition. It has similar histological features to pulmonary small cell carcinoma and is equally aggressive.
  
  
  METHODS
  We present the case of a 60-year-old woman who presented with right upper quadrant pain. Computerised tomography revealed an appendiceal lesion and multiple liver metastases. Exploratory laparotomy and right hemicolectomy was performed with histopathological analysis confirming a primary small cell carcinoma of her appendix.
  
  
  CONCLUSIONS
  This is the first reported case of a pure extrapulmonary carcinoma arising from the appendix.
