Abstract
Background: Sebaceous carcinoma (SC) is a relatively rare tumor that usually arises from the eyelid. Local extension down
the nasolacrimal duct is relatively rare event for SC.
Method: We herein report two cases of recurrent SC in the nasal cavity. Both patients had previously received primary
treatment for SC of the eyelid. Seven years after the initial treatment, the first patient presented with a mass on the left medial
canthus of the eyelid. Sixteen months after the initial treatment, the second patient presented with a large mass in the right
nasal cavity.
Results: The wide intraepithelial spread of SC over 30 mm from the initial surgical margin was beyond our expectations. The
first patient is currently alive with local recurrence following the administration of chemoradiotherapy 46 months after treatment,
while the second patient died of distant metastasis.
Conclusion: This report focuses on the unique clinical features of intranasal recurrence of SC after treatment.
