  • Title: A primary cutaneous non-T, non-B CD4+, CD56+ lymphoma.
    Author: Dummer R, Potoczna N, Häffner AC, Zimmermann DR, Gilardi S, Burg G.
    Journal: Arch Dermatol; 1996 May; 132(5):550-3. PubMed ID: 8624152.
    Abstract:
    BACKGROUND: Cutaneous lymphomas are heterogeneous clonal lymphoproliferative disorders originating from B or T lymphocytes. OBSERVATION: We describe a patient with a unique primary cutaneous lymphoma characterized by a bruise-like aspect of the skin lesions, a CD4+, CD43+, CD56+, CD2-, CD3-, CD8-, T-cell receptor-negative phenotype of the medium-sized to large lymphoid tumor cells and an undetermined genotype (T-cell receptor beta and immunoglobulin heavy chain in germline configuration, no clonal T-cell receptor gamma population as detected after analysis with polymerase chain reaction combined with denaturing gradient gel electrophoresis) and fast relapse after radiotherapy. CONCLUSIONS: This non-B, non-T cutaneous lymphoma cannot be classified by any current lymphoma classification. It seems to represent a new disease entity with peculiar clinical, histologic, and molecular features.
