Abstract:
An 82-year-old woman presented with a painless, progressively enlarging right neck mass of 2 years' duration. CT with contrast showed a 5.0 cm confluence of nodes just inferior to the right parotid gland. Fine-needle aspiration showed a lymphoproliferative disorder. Incisional biopsy showed sebaceous lymphadenoma. She subsequently underwent superficial right parotidectomy with neck dissection of level II-V (performed for enlarged lymph nodes causing significant pain). Facial nerve was preserved. She remained free of disease nearly 1 year postoperatively.
