Sebaceoma of the auricle

Abstract

AbstractObjective:To report a case of sebaceoma of the auricle, and to discuss the differential diagnosis, histopathological features, surgical management and genetic associations of this entity.Methods:Case report and review of the medical literature.Results:A 79-year-old man presented with a slowly growing lesion of his auricle. Excision of the mass and histopathological review revealed a benign, basaloid, adnexal neoplasm consistent with sebaceoma. Due to its association with Muir–Torre syndrome and increased risk of visceral malignancy, the patient was followed closely for signs of malignancy. At 36 months post-excision, there were no signs of recurrence; thereafter, the patient continued to receive routine cancer surveillance follow up.Conclusion:Sebaceoma is a rarely encountered, benign, adnexal neoplasm which can occur in the head and neck. The treatment is surgical excision, and recurrence is rare. Sebaceoma can occur as part of Muir–Torre syndrome, and in these patients there is an increased risk of other sebaceous lesions and visceral malignancy; thus, genetic testing and surveillance should be strongly considered.
