title: Sebaceous lymphadenoma of the parotid gland.
abstract: Sebaceous differentiation in salivary gland tissue is common. However, sebaceous neoplasms within the salivary glands are rare. We present the case of a sebaceous lymphadenoma with unusual features, arising in the parotid gland of a 60-year-old male. To the best of our knowledge, this is the first report of the ultrasound and MRI characteristics of this rare tumour. The difficulties encountered in reaching a definitive diagnosis both radiologically and histologically are described.
