Pityriasis rosea is a common skin disease that has been suspected to have a viral etiology. We performed nested polymerase chain reaction to detect human herpesvirus-7, human herpesvirus-6, and cytomegalovirus DNA in lesional skin, nonlesional skin, peripheral blood mononuclear cells, serum, and saliva samples isolated from 14 pityriasis rosea patients. Viral mRNA expression and virion visualization within lesional skin were studied by in situ hybridization and transmission electron microscopy, respectively. By nested polymerase chain reaction, human herpesvirus-7 DNA was present in lesional skin (93%), nonlesional skin (86%), saliva (100%), peripheral blood mononuclear cells (83%), and serum (100%) samples, whereas human herpesvirus-6 DNA was detected in lesional skin (86%), nonlesional skin (79%), saliva (80%), peripheral blood mononuclear cells (83%), and serum (88%) samples. By contrast, cytomegalovirus DNA was not detected in these tissues. Control samples from 12 healthy volunteers and 10 psoriasis patients demonstrated rare positivity for either human herpesvirus-7 or human herpesvirus-6 DNA in skin or serum. By in situ hybridization, infiltrating mononuclear cells expressing human herpesvirus-7 and human herpesvirus-6 mRNA were identified in perivascular and periappendageal areas in 100% and 75% pityriasis rosea skin lesions, respectively, compared to herpesviral mRNA positivity in only 13% normal skin and psoriasis skin controls. Transmission electron microscopy failed to reveal herpesviral virions in pityriasis rosea lesional skin. Nested polymerase chain reaction and in situ hybridization enabled detection of human herpesvirus-7 and human herpesvirus-6 in skin and other tissues isolated from patients with pityriasis rosea. These results suggest that pityriasis rosea is associated with systemic active infection with both human herpesvirus-7 and human herpesvirus-6.
