A case of eccrine cystadenoma was studied by electron microscopy. The tumor showed two types of cells, luminal and basal cells. The cells lacked the characteristics of the secretory segment of the sweat glands. The features of the luminal cells are similar to those of the intradermal portion of the eccrine sweat duct. In some areas, the lesion showed features characteristic of apocrine gland structure. Nuclear bodies were very frequent. The ultrastructural findings of eccrine cystadenoma support an origin from the ductal portion of eccrine sweat glands.
