Background:Various atypical variants of pityriasis rosea were published in the literature. There are very few reports abour pityriasis rosea being unilateral.Main observations:We present a female child who presented with acute onset of scaly eruptions clinically consistent with a diagnosis of pityriasis rosea, affecting only one side of the body involving waist, thigh, forearm and leg on right side.Conclusions:It is extremely unusual for pityriasis rosea to present the eruptions only on one side of the body. This case is presented here for its rarity in clinical practice.
