D69: Purpura and other haemorrhagic conditions

Purpura and other haemorrhagic conditions are a group of disorders characterized by abnormal bleeding or bruising. These conditions occur when small blood vessels burst under the skin, leading to blood spots, skin discoloration, or bruising, commonly known as purpura. Bleeding may also occur in other parts of the body such as nose, gums, gastrointestinal tract, or urinary tract, depending on the specific condition. The causes may vary, ranging from minor injuries, allergic reactions, certain medications, infections, to more serious underlying conditions like immune system disorders or clotting deficiencies. Symptoms can differ greatly, but they generally include unexplained or excessive bleeding, large areas of bruising, and reddish or purplish spots on the skin. The progression of these conditions can be either acute or chronic, depending on the nature of the underlying cause.
