A Parotid Mass

Alvin R. Solomon, MD; Kenneth D. McClatchey, DDS, MD; John G. Batsakis, MD

Arch Otolaryngol. 1981;107(5):294-296.

Abstract
• A new benign lesion of the parotid gland, the serous extravasation granuloma, occurred as a unilateral, painless parotid mass. Histologically, the mass was outlined by a fibrous capsule within which there was granulation tissue that was admixed with histiocytes and giant cells of a foreign-body type with abundant PAS-positive granules in their cytoplasm. Atrophic duct spaces and microsialoliths occurred within the lesion. Trauma to the parotid gland was the proposed origin.
