Basal Cell Adenoma
Solid basal cell adenoma is most common morphologic variant. This high magnification image of previous image depicts basal cell adenoma composed of two cell types – small cells with scanty cytoplasm and hyperchromatic nuclei at periphery of the cell island arranged in palisading manner and large polygonal cells with abundant cytoplasm and pale staining nuclei. The stroma is composed of spindle shaped myoepithelial cells. Mitotic activity is not increased.
