I was diagnosed with pityriasis rosea
At the end of February... for approximately 3 weeks, I presented with itchy red scaly plaques on my abdomen and it was diagnosed as pityriasis rosea. This was characterised by red oval-shaped spots and the presence of a larger very distinctive “herald lesion” that appeared about a week previous to the smaller spots. This is an unmistakable sequence of eruptions that leave no doubt during diagnosis.

While the exact cause of pityriasis rosea is unknown, it is believed to be associated with certain viruses.

However, it is important to note that evidence on this association, is conflicting.

The clue is that it often starts with one patch on the trunk which is usually at least a couple of centimetres in diameter, which can be confused with ringworm. We call this the ‘herald patch’ because it heralds an eruption 3-4 days later of smaller pink, scaly, oval shaped patches.

Other cases have been reported where lesions have erupted along areas of past trauma and scars, suggesting an isomorphic (Koebner’s) response.
