Sebaceous carcinoma of the parotid gland: a case report and review of the literature.
BACKGROUND
Sebaceous carcinoma is a rare malignancy primarily with aggressive growth affecting the cutaneous tissues of the periocular region. Sebaceous carcinoma of the parotid gland is exceedingly rare, with only 32 cases reported in the literature. Our case brings this total to 33.


METHODS
We present a case of a 57-year-old Moroccan woman with a firm, painless, slowly enlarging swelling at her left parotid area, with normal overlying skin and no palpable neck nodes. Parotidectomy with facial nerve preservation was performed, and microscopic examination showed sebaceous carcinoma. Then, she underwent adjuvant radiotherapy. With a follow up of 20 months, head and neck computed tomography revealed no recurrence.


CONCLUSIONS
The optimal treatment is unclear. With more cases reported, clinicopathological characteristics and histogenesis are increasingly understood. Therefore the treatment for this rare tumor continues to evolve.
