Abstract
Lingual choristomas or foregut duplication cysts are infrequently reported congenital anomalies that typically present in the perinatal period, and can cause respiratory or feeding problems. These cysts are lined by epithelial cells characteristic of the upper aerodigestive tract. We describe two children who presented shortly after birth with lingual cysts lined with squamous epithelium and foci of respiratory epithelium. Unlike previously reported lingual choristomas, these cysts did not contain gastrointestinal epithelium. In both these cases, the lingual cysts were successfully excised via a transoral approach. This article will discuss the histological findings in these two cases, the differential diagnosis and attempt to classify these lesions in the context of existing terminology.
