Suffering from Leukemia often causes the tiny blood vessels to burst beneath the skin. After a certain point, the production of abnormal blood cells ends up acting as a barrier to the normal production of platelets. Therefore, it might happen that the body might not have enough platelet count to block the burst capillaries, and as a result, the blood seeps out into the skin .
This leakage results in red, purple or brown tiny spots called petechiae and you can pinpoint red dots on skin . A certain collection of these petechiae often look like a rash. A fruitful way to distinguish petechiae from a rash is by pressing down on the affected spot of the skin. If it is a rash, the colour will change into white, and if it is a petechia, there would not be any change in the colour of the spot.
