What appears purple spot skin ' Purpura)
Purple spot or purpura reflects that there is more subcutaneous hemorrhage. The color is relatively red at the beginning, as time passes turn purple or turn yellow. As soon as some people touch wiping, some skin will present a piece of silt spot, even some people have not collided, the skin presents the silt spot too. This kind of phenomenon see more on clinic, especially woman. Through check, have, find, ask " getting simple purpura " unusually while being other in many aspects ,It is the early manifestation of a certain bleeding disease sometimes, noteworthy. Summing up the reason why subcutaneous hemorrhage forms the purple spot has three following respects:


1,Blood platelet reducing purpura: The blood platelet is lower than normally in the human blood. Because the blood platelet is that the blood solidifies one of the most important factors in the mechanism, it is apt to bleed to reduce. The more reduce, the more bleeding chances are. Specially see more the sending blood platelet is purple and paralysed, regenerated obstacle anaemia (produce the blood platelet obstacle in bone marrow) , leukemia (bone marrow is filled by the leukaemia cell, influence the blood platelet to turn into) , take a certain medicine, infect seriously and huge spleen cause spleen function hyperfunction, etc.

2,Capillary pathological change: Because capillary damage, blood apt to leak to skin downing, causing purpura from capillary, a most common one for anaphylactic purpura, can because take a certain medicine, food or suck a certain material, cause. This kind of purpura is distributed, had one more pair of symmetrical characteristics of side.

3,Blood coagulation obstacle: Have by more than 10 kind blood coagulation factor at human body,the factor scarce, be can if you can't cause, bled. If the factor lacks and sees Yu Jia is a kind of hemophilia; Liver disease can cause the reduction of thrombinogen, so serious liver disease have more subcutaneous hemorrhage.

Generally speaking, appear the intersection of skin and purpura should expect the intersection of blood platelet and reduce, the intersection of capillary and pathological change and blood coagulation obstacle except simple purpura repeatedly, must check in an all-round way to the hematology.
