In pilar sheath acanthoma, there is a lobular proliferation of benign squamous epithelium in the dermis (figure 1, 2). These lobules surround small cystic spaces. The lining cells may have a granular layer similar to an epidermoid cyst (figure 3) or have an attenuated granular layer similar to a trichilemmal cyst (figure 4).
