An update on Epstein-Barr virus-and human T-lymphotropic virus type-1-induced cutaneous manifestations. CME Part II.

The Epstein-Barr virus (EBV) is a DNA virus that infects 90% of the human population, is responsible for certain cutaneous lymphomas (extranodal NK/T-cell lymhoma, hydroa vacciniforme lymphoproliferative disorder, lymphomatoid granulomatosis, others), and can be associated with a variety of cutaneous manifestations (eg, infectious mononucleosis, severe mosquito bite allergy, chronic active EBV disease, Gianotti-Crosti syndrome). EBV-related skin disorders are frequent in certain populations (South and Cental America, Africa, Asia, and Oceania) and can be diagnostically challenging. The human T-lymphotropic virus type-1 is a retrovirus, which is known to be associated with adult T-cell leukemia/lymphoma, neurologic disorders, but also cutaneous non-neoplastic manifestations (infective dermatitis, infections, and infestations). We performed an updated revision of the clinical dermatologic and histopathologic findings associated with the cutaneous non-neoplastic and preneoplastic disorders occurring in association with the EBV and human T-lymphotropic virus type-1.
