Pityriasis Rosea

Causes

Pityriasis rosea is a bumpy scaly rash that appears on the trunk and the part of the arms and legs closest to the trunk.   It may follow a prodrome of flu like symptoms.  A herald patch, a large solitary lesion, is often the initial sign  followed by the typical rash one to two weeks later.  The scaly bumps follow the lines of cleavage forming a christmas tree like pattern.  Individual lesions are characteristically oval or round with a dusky scaly center and a red boarder.     It can be a little itchy.

Treatment

Pityriasis Rosea usually heals without treatment in two to four months.  A moisturizer is recommended for scaly areas.
