A Case of Sebaceous Lymphadenoma of the Parotid Gland

Abstract

We report herein on a case of sebaceous lymphadenoma arising from the parotid gland. A 53-year-old woman presented with a five-year history of progressive and painless swelling in the right parotid region. Magnetic resonance imaging (MRI) displayed a well-circumscribed lesion within the right parotid gland. Fine-needle aspiration cytology was performed with ultrasound guidance, and the tumor was diagnosed as a suspected adenoid cystic carcinoma. The parotid tumor was removed with a superficial parotidectomy and pathological examination revealed a sebaceous lymphadenoma. The postoperative course was uneventful, with no signs of recurrence for 8 months after the operation.

Sebaceous lymphadenoma of the parotid gland is extremely rare, and only 51 cases have been reported, including our case. The clinical characteristics of sebaceous lymphadenoma are discussed.
