Abstract:
We report the case of an extranodal non-Hodgkin's lymphoma mimicking a benign tumor in the left parotid gland of a 71-year-old woman. The clinical presentation of the painless, mobile mass was suggestive of a benign parotid tumor such as an adenoma. The intraglandular tumor appeared sonographically as a well-circumscribed, hypoechoic, homogeneous, lobulated mass with mild distal sound enhancement. Power Doppler sonography showed marked intratumoral vascularization. The tumor was resected by lateral lobectomy of the parotid gland and was found histopathologically to be a diffuse large B-cell lymphoma.
