Abstract

Amyloidosis in the parotid gland is rare and is usually associated with systemic amyloidosis. Localized amyloidosis in the parotid gland is extremely rare. We present a case of localized light chain amyloidosis of the parotid gland without systemic involvement. A 70-year-old woman presented with an asymptomatic swelling of the right parotid region. The findings of a physical examination, hematologic and biochemical investigations, imaging, and cytology were inconclusive. The patient underwent an extracapsular dissection of the right parotid gland. Histologic analysis showed that the tissue of the right parotid gland mostly consisted of amyloid deposition. The amyloid stained with antibodies to lambda light chains. Additional investigations showed no systemic involvement. The patient is asymptomatic 5 months after surgery. Clinicians should be aware of the possibility of localized amyloid light chain amyloidosis in the parotid gland, especially if magnetic resonance imaging, computed tomography imaging, and ultrasound findings are inconclusive, and they should recognize, evaluate, and treat it accordingly.
