XXXX presenting as a parotid gland mass: Expanding the differential diagnosis of giant cell-rich lesions in salivary glands.

@entity5 @entity82 @entity527 @entity2967
@entity2967 ( @entity2967 ) are rare benign soft tissue @entity5 affecting mostly young adults. The most common affected sites include the knee, ankle, elbow, shoulder, and fingers. The temporomandibular joint is occasionally affected. Herein, we report a case of a 31-year-old Caucasian male who presented clinically with a parotid gland mass. The initial clinical and radiological work-up failed to reveal any involvement of the adjacent temporomandibular joint. Fine-needle aspiration revealed a cellular @entity5 composed of mononuclear and multinucleated giant cells with @entity82 and @entity527 . This was subsequently found to be a @entity2967 arising from the temporomandibular joint. Giant cell-rich lesions are uncommon in salivary glands. Herein, we describe the cytomorphology and clinico-radiographic features of this @entity5 with emphasis on the differential diagnosis of giant cell-rich lesions presenting in salivary glands. Despite its rare occurrence, this entity should be considered when giant cells are prominent in specimens acquired from this location.
