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.
一种新的腮腺良性病变——浆液外渗性肉芽肿，表现为单侧无痛性腮腺肿块。组织学上，肿块由纤维包膜包绕，包膜内有肉芽组织，其中混有组织细胞和异物型巨细胞，其细胞质内有丰富的PAS阳性颗粒。病变内可见萎缩的导管腔隙和微小涎石。腮腺外伤被认为是其起源。
