Salivary Duct Carcinoma (SDC) is a distinctive and clinically aggressive adenocarcinoma of salivary origin. It arises from the ductal epithelium, predominantly occurring in the major salivary glands, especially the parotid gland. Here, we report a case of an extensive salivary gland pathology involving the right side of face, possibly arising from the parotid gland in a 25-year-old male patient. On routine histopathology, the tumour mass revealed a papillary pattern of neoplastic ductal epithelial cells showing comedo-like-central necrosis. Immunohistochemical staining showed tumour cells in the infiltrative component to be diffusely immunopositive for cytokeratin-7 and Her-2, confirming the diagnosis of SDC. This paper presents a case report on salivary duct carcinoma and highlights a review on histological variants of salivary duct carcinoma.
