Histopathologic Findings, Hematoxylin-Eosin A and B, A dense, nodular infiltrate composed of small- to medium-sized pleomorphic lymphocytes in the entire dermis. A, Lymphocytes show folliculotropism and focally epidermotropism (original magnification ×10.) B, Lymphocytes showed cytologic atypia with irregular nuclear membranes and hyperchromatic nuclei (original magnification ×40). C, Most of the lymphocytes express CD4 (original magnification ×10). D, Most of the lymphocytes coexpress CD5 (original magnification ×10). E, Many CD4+ lymphocytes coexpress CD10 (original magnification ×10). F, Staining for CD20 shows many CD20+ B lymphocytes, representing almost half of the infiltrate (original magnification ×10).
