Photomicrograph of skin lesion of case 2. (A) Low magnification showed a sharply demarcated tumor made up of multiple basaloid lobules in the deep dermis. (B) Concentrically, densely packed round nests or cell balls of pale cells in the central part of the lobules with peripheral palisading. (C) Bcl-2 was stained prominently in the out layer tumor cells with the centrolobular cell balls non-stained. (D) P63 showed weaker staining in the central part than those in the periphery.
