Abstract:
Intestinal duplication cysts are rare congenital anomalies that may occasionally undergo neoplastic change. We report the case of a 30-year-old woman who was diagnosed to have a caecal duplication cyst. The cyst was excised and histology revealed the presence of a 10 mm diameter carcinoid tumour within the cyst wall. There was no evidence of metastatic spread and the patient remains well after 2 years follow-up. The 3 previously reported cases of carcinoid tumour arising within duplication cysts are reviewed.
