Correlations of unique clinical, immunotypic, and histologic findings in cutaneous gamma/delta T-cell lymphoma.

Journal Article

Cutaneous T-cell lymphoma is a malignancy of T cells that express a clone-specific heterodimer T-cell receptor for antigen. The second recognized case of an epidermotropic malignancy of T-cells expressing gamma/delta T-cell receptor-expressing cells is reported. The immunophenotype of the malignant T-cells was CD3+, CD2+, CD7+, gamma/delta T-cell receptor+, CD4-, CD8-, and alpha/beta T-cell receptor-. The clinical features were remarkable for extreme epidermotropism with a scant dermal lymphomatous infiltrate. Profound keratinocyte necrosis occurred in areas of malignant skin infiltrates. Despite cutaneous lesions covering more than 50% of the skin surface of the patient, no adenopathy or splenomegaly was detected. The intense epidermotropism of this patient's gamma/delta T-cell receptor-expressing cells and the putative cytolytic properties of CD4- CD8- gamma/delta contributed to the destruction of epidermis. Remission was induced with a combination of electron beam and extracorporeal photochemotherapy.
