Abstract: It is rare to find tumor of the ceruminous gland, which is a modified apocrine gland located within the skin of external auditory canal (EAC). Syringocystadenoma papilliferum (SCAP) is a benign adnexal tumor that occurs in the head and facial area in forms of infiltrative macules, papules, or keratinous nodules, but rarely in the EAC. To date, fewer than 150 case reports of SCAP have been reported, with SCAP in the EAC being extremely rare. We report a case of 51-year-old male with 2 year-history of a left EAC mass arising from the superior wall of the EAC. We performed a microscopic surgery, with the mass resected via retro-auricular approach under general anesthesia. The histopathological examination confirmed the specimen as SCAP. There were no complications or recurrence during the 4 months follow-up period.
