Cutaneous Destombes–Rosai–Dorfman disease: absence of detection of HHV‐6 and HHV‐8 in skin

Abstract

This study suggests that HHV-8 is not involved in the pathogenesis of cutaneous DRDD. However, this should be confirmed by further studies. We can postulate three hypotheses in regard to HHV-6 role in DRDD pathogenesis: 1) its presence in lesionnal tissues is fortuitous, 2) HHV-6 plays a role in promoting more aggressive diseases and 3) various causes, including HHV-6, are implicated in the pathogenesis of DRDD.
