Question: Diamond Patterned Rash On Back need help-includes pictures

 b8tzm - Tue Mar 30, 2010 8:53 am

I have had a diamond shaped pattern of rashes in 1 spot on my back for 24 hrs. It is not raised and it does not itch. Can anyone tell me what this is? I have links to two pictures that are real good. Thanks ... 1782qaljFw ... 1782SpEwzK

User avatar Hello,You have posted a very interesting observation.The diamond shaped areas probably represent the marking on the cloth you wore or contact to a seat with similar markings.
The condition could well be purpuric contact dermatitis to textile.This is an unusual reaction manifested as a vascular reaction possibly to acrylic material.
Textile dye patch test could give a diagnosis.Disperse blue dyes are common sensitisers.
Other causes of ecchymosis need to be ruled out too.Do consult a dermatologist for patch tests and other investigations.
Best wishes.
