CD4/CD8 double-negative mycosis fungoides: A case report and literature review

Abstract

Mycosis fungoides, the most common subtype of cutaneous T-cell lymphoma, displays a broad spectrum of clinical, histological and phenotypic variants with different prognostic impacts. The classic immunophenotype is CD3+/CD4+/CD45RO+memory T cells. CD4/ CD8 double-negative mycosis fungoides is rare. Here we describe the clinicopathological features of CD4/ CD8 double-negative mycosis fungoides in a 55-yearold female with a review of the literature. Although the CD4/CD8 double-negative phenotype appears to be associated with an unusual clinical presentation, it does not appear to confer prognostic significance.
