Sebaceous carcinomas of the eyelid are rare neoplasms, accounting for less than 1% of all eyelid tumors, but they frequently metastasize to regional lymph nodes. The five-year survival rate is about 50% among patients who develop metastasis to lymph nodes of the neck. Often, the macroscopic border of a tumor does not match the microscopic findings. Therefore, the tumor should be removed with a safety margin of at least 5 mm, considering the possibility of local recurrence. We experienced two cases of lower eyelid sebaceous carcinoma. After tumor resection, eyelid reconstructions were performed using the malar flap with the hard palate composite graft (periosteum and mucosa). Good results were obtained for these cases. Nowadays, it is rare for otolaryngologists to treat patients with sebaceous carcinoma. However, the chance of head and neck surgeons having to treat these patients is expected to increase in future.
