A 48-year-old man with chronic right submandibular swelling had obstructive sialadenitis from a hilar stone and underwent gland excision.
A 48-year-old man with hypertension and no diabetes or other systemic illness presented with chronic right submandibular swelling. Constitutional symptoms and relevant drug or exposure history were not reported.
Neck ultrasound showed a mildly enlarged heterogeneous right submandibular gland, a 6 mm echogenic hilar focus consistent with a sialolith, mild ductal dilatation and inflammatory change, and reactive cervical nodes with preserved architecture. The remaining salivary glands, thyroid and laboratory studies were normal.
The diagnosis was obstructive sialadenitis caused by a hilar sialolith. The patient underwent right submandibular gland excision under general anaesthesia; no complications were reported.
Histology confirmed non-specific chronic sialadenitis due to stone-related ductal obstruction, with no malignancy.
The legacy record did not document the postoperative course. Standard postoperative assessment and follow-up of the wound, nerve function and reactive lymphadenopathy were planned.
