Hamartoma, oesophageal

benign tumour characterized histologically by metaplastic respiratory epithelium and islets of cartilage in a fibrous stroma. They can be solitary or may be multiple as part of the Cowden disease.

Radiographically they have a variable appearance on the barium study of the oesophagus. The solitary form presents as a nonspecific intraluminal pedunculated and smoothly lined filling defect. In patients with multiple hamartoma syndrome they present as numerous very small sessile lesions causing a small sharply demarcated filling defect on double contrast barium study of the oesophagus. Also, see Cowden disease.
