A Case of Tubular Apocrine Adenoma with Syringocystadenoma Papilliferum of External Auditory Canal Removed by Postauricular Approach / 대한이비인후과학회지

ABSTRACT

Tubular apocrine adenoma (TAA) and syringocystadenoma papilliferum (SCAP) are uncommon cutaneous adnexal neoplasms often found in the head, perianal area, but rarely in external auditory canal (EAC). SCAP in EAC generally presents itself with a mass in the EAC along with conductive hearing loss. We present here a case of a 50-year-old man presenting TAA with SCAP confined to EAC, which was surgically removed. The clinical and histopathological features were described. The patient has been well without relapse or metastasis.
