Abstract |
Mammary analogue secretory carcinoma (MASC) is a rare malignant tumor of the salivary gland, which was
first described in 2010. 1) In this case report, we describe a 62-year-old woman with a MASC of the parotid gland,
who initially presented with an asymptomatic preauricular mass. At first, computed tomography (CT) and fine needle aspiration cytology were performed; these suggested a possible Warthin’s tumor but also some suspicious malignant findings. For the main treatment, adequate parotidectomy was conducted via modified Blair incision to remove the tumor. Postoperative pathology report revealed a MASC of the parotid gland. Specific MASC findings were observed upon immunohistochemical examination. |
