The tumor was circular, nodular, soft with a greyish coloration, around 1.2 cm in diameter (Fig. 1).
Histological aspect of the mass. Well-circumscribed nodule, with smooth borders, constituted by lobules of basophilic and clear cells separated by homogeneous collagenous material. On the top there is a cystic dilated space full of sweat (A). At higher magnification, it is possible to appreciate that the two cell populations intermingle each other. Cytological atypia, mitotic figures or necrosis are absent (B, C, D).
