In the group of primary cutaneous T-cell lymphomas, T-cytotoxic and natural killer cell lymphomas have been recently recognized as distinct and rare clinicopathologic entities. Typically, cytotoxic granules associated proteins TIA-1, granulolysine and perforin, and cytotoxic-natural killer (NK) cell markers CD8+, CD56+, CD94+, CD161+, NKp46+ are expressed by tumoral cells. Five T-cytotoxic and NK cutaneous lymphomas subtypes are actually recognized: subcutaneous panniculitis-like T-cell lymphoma, extranodal nasal and nasal-type NK-T cell lymphoma, blastic NK cell lymphoma, aggressive epidermotropic CD8+ cytotoxic T-cell lymphoma, cutaneous gamma-delta peripheral T-cell lymphoma. In this review, the most important clinical, histological, immunohistochemical and molecular data are analyzed together with differential diagnostic aspects between these entities. T-cytotoxic and NK cutaneous lymphomas pursue a very aggressive course, with poor outcome and high mortality rate, with few exceptions.
