A, MF lesions on the thigh. Multiple erythematous scaly patches with vague annular borders on both anterior thighs. Some of them are covered by hemorrhagic crust due to an irritation. B, Diffuse atypical lymphocytic infiltrate affecting full thickness of the epidermis and the dermoepidermal junction. Mild perivascular atypical lymphocytic infiltrate was also present in upper dermis. Atypical lymphocytes were CD3+ T cells (C), negative for both CD4 (D) and CD8 (E). Few reactive T cells expressed either CD4 or CD8 in the upper dermis. F, Cutaneous follicular center lymphoma on the scalp. An enlarged 2×2 cm nodule on the left posterior scalp. The neoplasm infiltrated the entire dermis (G). Tumor showed follicular growth pattern with predominance of large centroblasts (G, inset). The neoplastic cells were positive for CD20 (H), BCL6 (I); they were negative for BCL2 (J). (Original magnifications: B-E, ×200; G, ×2; G inset, ×400; H-J, ×100.)
