Can you classify purpuric spots or haemorrhagic spots?
They are classified as below:
Thrombocytopenic (quantitative defects)—ITP, drug-induced (quinine, heparin,
penicillins), aplastic anaemia, infections, SLE, SBE, acute leukaemias.
Non-thrombocytopenic
– Vessel wall abnormalities—HSP, infections (e.g., meningococcus), senile purpura,
Cushing’s syndrome, scurvy, uraemia, vasculitis.
– Platelet functional defects (qualitative defects)—thrombasthenia or Glanzmann’s
disease.
NB: ITP (idiopathic/immune thrombocytopenic purpura) is an autoimmune disorder
which leads to immune-mediated destruction of platelets. It is common in females
and has two forms, acute and chronic.
