Lingual Foregut Duplication Cyst: A Cytologist's Viewpoint

Foregut duplication cysts are rare congenital anomalies that can occur anywhere along the gastrointestinal tract, including the tongue. They are usually diagnosed by imaging studies; rarely, aspiration cytology is performed. Fine needle aspiration cytology (FNAC) can help to differentiate foregut duplication cysts from other types of tongue lesions, such as dermoid cysts, lymphangiomas, or malignancies. Present report describes FNAC findings of this condition in a seven year old girl who presented with a painless swelling on the dorsal aspect of her tongue for the past 5 months.
