Case Discussion

Findings favour enlarged intraparotid node in superficial lobe of left parotid gland. Normal gland shows presence of nodes; however, this one was big enough to be called abnormal. A smaller node is seen on right side.

Excision biopsy of left parotid gland lesion. Histopathology - Granulomatous lesion. Differential diagnosis given was sarcoidosis and tuberculosis.

Test for sarcoidosis - ACE (Angiotensin converting enzyme ) - negative.

Aetiology now presumed to be tuberculosis, which is common in the patient's geographic area.
