Cutaneous lymphomas represent a heterogeneous group of disorders with preferential skin involvement by malignant lymphocytes.1 Extranodal sites, such as the skin, provide distinct microenvironments for lymphoid cell proliferation. The tumor cells of cutaneous lymphomas are more likely to be T cells (65%) than B cells (25%).2 The converse is true in lymph node–based lymphomas, where B-cell lymphomas are more common than T-cell lymphomas.
