Foregut cystic developmental malformations (FCDM) are a type of rare cystic lesion. The occurrence of FCDM is exceedingly uncommon in the intraoral location. We report three cases of FCDM with intraoral location who presented at Chacha Nehru Bal Chikitsalaya, New Delhi, India, in 2016, 2017 and 2018 with symptoms of respiratory distress and feeding difficulties. Two patients were male and one was female with an age range of 29 days to eight years. The clinical differential diagnosis included mucocele, ranula, dermoid, lymphangioma, teratoma, thyroglossal duct cyst, etc. All patients were treated with simple surgical excision and diagnosed, based on histopathology, with FCDM. These should be considered as differential diagnosis of head and neck midline cystic mass lesions. This case report aimed to discuss differential diagnosis and appropriate terminology for these cystic masses as there is varied and ambiguous nomenclature.
