Eccrine poromas are benign, slow-growing, solitary tumors originating from the intraepidermal portion of eccrine sweat ducts. Approximately 65% of these tumors occur on the soles of the feet, while 10% occur on the hands where a high concentration of eccrine sweat glands exists. Less frequently it occurs in other sites such as neck, chest, forehead, nose, and scalp with sporadic occurrences. A 43-year-old Korean female presented with a mass on her right auricle, which had been present for 5 years. The mass increased gradually in size with pain, oozing, and bleeding. A biopsy of the mass revealed monomorphic basaloid cells, which may extend into the underlying dermis, in a richly vascularized stroma, with a variable number of cystic or ductal structures. The patient was diagnosed as having eccrine poroma. In this case, the eccrine poroma showed unusual clinical presentation
