Carcinoid Tumour of Caecum: an Unusual Palpable Mass in the Right Iliac Fossa.

Carcinoid tumour represents 0.8-1.5 % of malignant digestive tumours. Gastrointestinal (GI) carcinoids account for 95 % of all the carcinoids, and caecal carcinoids account for 5 % of all the carcinoids. These tumours are frequent in women (2-4:1) as reported by Spallitta and Termine (Minerva Chir 55:77-87, 2002). In order of frequency, they may occur in the appendix (35 %), ileum (28 %), rectum (13 %) and bronchi. Incidence is less than 1 % in the pancreas, gall bladder, liver, larynx, testes and ovaries. The colon and ileocaecal region are rare sites of origin for gastrointestinal carcinoids as reported by Soga (J Exp Clin Cancer Res 17:139-48, 1998). They remain asymptomatic for years and many a times are diagnosed endoscopically, intraoperatively or during autopsy, based on their histopathological findings. We present a rare case of caecal carcinoid.
