Epstein-Barr virus-associated lymphoproliferative disorder of granular lymphocytes presenting initially as cutaneous vasculitis.
Lymphoproliferative disorders of granular lymphocytes (LDGL) represent a family of diseases characterized by persistent granular lymphocytosis with variable prognosis. The Epstein-Barr virus (EBV) has been occasionally linked with the development of LDGL. However, cutaneous manifestations of LDGL have rarely been reported. One patient had cutaneous vasculitis for 10 years before a definite diagnosis of LDGL was made. Chronic EBV infection was documented serologically and EBV DNA was detected in the peripheral blood lymphocytes. EBV RNA was detected in the nuclei of infiltrating lymphoid cells expressing CD43 in a skin biopsy specimen. A cytogenetic study showed clonal chromosomal abnormalities. This is the first report of EBV-associated LDGL of natural killer cells with cutaneous manifestations.
