Adnexal carcinoma of the scalp: aggressive sebaceous differentiation with invasion of the orbital wall and thoracic vertebra

Tumors of the scalp are characterized by a heterogeneous clinical spectrum with site-specific features. A wide variety of tumors that arise in the scalp include neoplasms, hamartomas, malformations, and both benign and malignant cysts. Most scalp tumors are benign (98 –99%) with only an estimated 1–2% of diagnosed cases reported as being malignant. Of these, adnexal carcinoma is reported in less than 1% of cases. Herein, we report a 65-year-old woman who presented with pain and numbness in her hands with past medical history significant only for a chronic pos terior head mass that had never received workup.
