thrombocytopenia - deficiency of platelets in the blood. This causes bleeding into the tissues, bruising, and slow blood clotting after injury. A 16 year old boy presented to a doctor by his mother for the injury which he had recently during cycle riding. On examination doctor noticed the loose, overly-flexible joints, smooth or stretchy, easily-bruised skin and abnormal wound healing and scar formation. This is the characteristic feature of the disorder known as - Ehlers-Danlos syndrome ...
