Unilateral laterothoracic exanthema

A 10-year-old Caucasian boy was referred for evaluation of an acute eruption that had developed over the past 8 days. The eruption began in the right popliteal fossa, and then coalesced and spread along the right side of his body. Fever up to 38 ºC and joint pain were reported 3 days before the appearance of skin lesions. Physical examination showed erythematous and edematous macules and papules on his right hemibody (Figure). The left hemibody did not show any skin lesions. Laboratory test performed showed IgM positivity for parvovirus B1 9.
