There are purple spots on the thighs

Purple spots suddenly appear on the thighs. Why does this happen? Some people think that it is caused by damage to the small blood vessels in the capillaries and blood reflux disorders.

(1) Simple purpura generally has no systemic symptoms . Scattered bright red bruises the size of a needle tip may appear on both lower limbs and do not fade when pressed. After seven days, the color gradually fades and disappears. But new petechiae appear.

The disease is characterized by sudden onset, fever, extensive skin bleeding, large ecchymoses and hematomas, mucosal and urogenital bleeding, and a significant decrease in platelets, which may be less than 5,000/mm3. The chronic type is more common, more common in young women, with a slow onset and persistent or recurrent bleeding. Severe bleeding may occur not only on the skin, but also on the mucous membranes or internal organs.
