Case Reports Collision sebaceous and basal cell carcinomas of the eyelid B

Objective: To report a rare case of collision sebaceous and basal cell carcinomas of the eyelid. Design: Interventional case report. Methods: An 80-year-old woman presented with a nodular lesion at the center of the left lower eyelid. Small ulceration and madarosis were also present. Results: The patient underwent excisional biopsy with frozen section control. Histopathology showed mixed sebaceous as well as basal cell carcinoma with uninvolved surgical margins. Oncologic survey did not disclose any other lesion. At 6-month follow-up, there was no evidence of recurrence, new lesions, or metastasis. Conclusion: Sebaceous and basal cell carcinomas can coexist in the eyelid within the same clinical lesion. Because of the potential risk of metastasis of sebaceous carcinoma, close follow-up of the patients is advisable.
