Eccrine Spiradenoma

A 20 year old man presented with a tender nodule in his left leg. The nodule was excised and showed lobules of epithelial cells with ductal differentiation (indicating sweat gland origin). The lobules were formed mainly of pale cells, with darker cells at the periphery. The lobules were surrounded by dense lymphocytic infiltrate. Areas of duct formation that is filled with esinophilic material were seen together with areas of squamous differentiation and the presence of hyaline material separating the cells into cords.
