Dermal duct tumor.
A dermal duct tumor which clinically resembled an intradermal nevus and developed on the lower back of a 59-year-old woman is described. The diagnosis could only be reached by microscopic examination. The dermal duct tumor appears to originate from cells with differentiation towards the intradermal portion of the eccrine sweat duct.
