Obstructive adenitis is common disorder of submandibular gland. Sialolithiasis is the most common etiologic factor causing obstruction. If a sialolith is not detected, chronic obstruction of salivary glands is called nonspecific sialoadenitis. Foreign body-associated sialoadenitis of submandibular gland is very rare within the literature. In this study, the authors presented a patient having an unrecognized foreign body in the submandibular gland beside the duct that was causing chronic sialoadenitis. Foreign bodies must be explored and all suspected areas must be examined carefully for avoiding secondary problems and surgeries in the future.
