Purpura

Its characteristic feature is multiple pinpoint hemorrhages, the appearance of which depends on the type, duration, and initial severity of purpura. It looks like a rash, initially red in color, gradually darkening to purplish, then forming a brownish-yellow color, which later disappears. The remaining pigmentation depends on the type of unabsorbed pigment. Rashes can occur on mucous membranes and internal organs.

Idiopathic thrombocytopenic purpura is of unclear etiology, manifesting as thrombocytopenia and a hemorrhagic syndrome. Thrombocytopenia is most commonly caused by autoimmune processes, triggered by certain infectious factors or medications taken. The predominant gender is female, with an age of around 14 years.

Thrombotic thrombocytopenic purpura manifests as a hemorrhagic syndrome of the skin and increased thrombus formation, leading to ischemia of internal organs. The predominant age group is 40-60 years, with females being the most commonly affected.
