Although a swollen parotid represents a diagnostic challenge, with thorough investigation it is possible to differentiate the benign from the serious causes.
As a GP working in your own practice and the local emergency department, you are frequently asked by patients to look at various lumps and bumps.
It has been a busy Saturday afternoon in the emergency department when you pick up the next waiting patient: a 75-year-old man who presents with left-sided facial swelling. The patient reports three days of gradually increasing swelling and worsening pain on the left side of his face. He denies any hot or cold sweats, recent illnesses, trauma, travel or dental issues and there is no evidence of immunocompromise.
