Junctional CD8+ Cutaneous Lymphomas With Nonaggressive Clinical Behavior

Abstract
MOST CUTANEOUS T-cell lymphomas (CTCLs) have the phenotype of T-helper memory lymphocytes (CD3+, CD4+, and CD45R0+).1,2 Only a minority of cases present with other phenotypes, such as CD3+, CD4, CD8, or CD3+CD8+,3,4 or with the spectrum of CD56+ lymphomas.5-7 The primary cutaneous lymphomas with the phenotype of cytotoxic/suppressor (CD8+) T cells have been of significant interest in the recent literature.8-12 The detailed analysis of histological and clinical features in several cases has led to the conclusion that CD8+ T-cell lymphomas represent a distinct type of CTCL with an aggressive clinical behavior.4,12
