摘要

Salivary calculus is the most common cause for obstructive sialadenitis of submandibular gland. Foreign body causing obstructive sialadenitis is rare due to the anatomical and physiological factors preventing it from migrating into the duct. Our case report aims to highlight an unusual presentation of foreign body in the submandibular duct with the background of calculus formation and it’s missed diagnosis in the usual radiological investigations like CT. Sialendoscopic retrieval revealed finger nail as the foreign body nidus with calculus deposits at one end of the nail.
