Histopathological case report of high grade salivary duct carcinoma

Abstract

The case of a 39-year-old man with slowly growing mass in the superior part of left parotid region is described. Patient presented neurological symptoms including hypomobility of lower left eyelid and inability of complete closure of left side eyelids resulting in conjunctivitis and hyperlacrimation. Routine physical examination supported by image and laboratory tests was performed. Pathomorphological results of hematoxylin and eosin staining as well immunohistochemical examination in view of clinical presentation pointed to diagnosis of high grade salivary duct carcinoma. Rare incidence, histological view similar to breast cancer and body localization are sufficient reasons for further analyses and descriptions of this type of lesions.
