A Case of Unilateral Pityriasis Rosea
Authored by Gülhan Gürel
Pityriasis rosea (PR) is an acute, self-limited disease, characterized by squamous maculopapular lesions on the trunk and proximal extremities. Unilateral PR is an extremely rare form reported in both children and adult in which the lesions are located on one side of the body. A 50-year-old female patient was admitted to our clinic with multiple red, scaly, asymptomatic lesions over the left side of the trunk and abdomen. Viral DNA isolation was performed by extraction of nucleic acid from serum. Pathogen-specific primer was used to detect DNA from HHV-6 using real-time polymerase chain reaction (PCR) (Bosphore HHV-6 Detection Kit v1). HHV-6 DNA was negative in serum for our patient. The structure of organic tissue and various structures were seen but the consuetudinary image of herpes virus was not found. This case is presented due to its rarity in clinical practice. Further studies of possible triggers for virus activation on an unilateral side of the body in acute PR are needed in order to elucidate the pathophysiology involved.
