It is transmitted through saliva and other bodily fluids. Mononucleosis, commonly known as mono, is a viral infection. The symptoms of leukaemia include fever, chills, fatigue, unintentional weight loss, swollen glands, bruising, nosebleeds, and night sweats.Ī respiratory tract bacterial infection may show signs of fever, headache, muscle pain, and nausea. It can also form due to friction against the skin due to carrying a heavy bag or a tight strap of clothing and a sunburn.īone marrow cancer is known as leukaemia. The symptoms of hantavirus pulmonary syndrome include breathing difficulties, fatigue, fever, and muscle pain.Īny damage to the skin, such as biting, hitting, or a car accident, may cause petechiae. When the heart’s inner lining gets infected, the patient develops symptoms such as fever, chills, fatigue, joint and muscle pains, breathing difficulties, and pale skin.Ī viral infection shows symptoms similar to the flu. It is a viral illness with symptoms of fatigue, fever, sore throat, and muscle pain. The other causes include the following: Possible Cause The two most common causes are infections and reactions to medications. When the blood vessels break open, the blood leaks into the skin, forming petechiae. You may develop petechiae anywhere in the body, sometimes noticed inside the mouth or eyelids. If you notice larger, red, or purple spots, it is one of the types of bleeding problems known as purpura. However, when applying pressure on rashes, they turn pale, but the colour of the petechiae remains the same. Several petechiae in one place may look like a rash. What Does Petechiae Look Like?Īs mentioned above, petechiae appear as flat, pinpoint-sized red, brown, or purple dots. When you press on petechiae, it remains purple, red, or brown, whereas a rash turns pale or lighter when applied pressure. They are pinpoint red dots on the skin developed due to broken blood vessels under the skin. The appearance of petechiae may look like a rash, but it isn’t one. This event and disruption of several other physiological events manifest into petechiae (superficial lesions) and purpura (deep lesions). It disrupts the whole assembly, the endothelial barrier becomes leaky, and erythrocytes (blood cells) enter the surrounding tissues. A noticeable decrease in the platelet count (10,000-20,000/cubic millimeter) occurs during thrombocytopenia. Petechiae, a hemorrhagic lesion that involves excessive bleeding, is a common phenomenon associated with thrombocytopenia. Platelets are closely associated with regulating pro-angiogenic factors, such as vascular endothelial growth factor (VEGF), angiopoietin 1, etc. The blood clot is a series of controlled events that require endothelium (exposed), tissue factor, collagen, platelets, platelets activating factors (PAF), prothrombin, fibrinogen, von Willebrand factors (vWF), and other cofactors to work. Purpura is bigger than the petechiae and develops due to bleeding within the skin, and its size is more than 2 mm. Both petechiae and purpura are non-blanching spots. These spots are non-blanching as they do not disappear on applying pressure. It occurs due to intradermal (between epidermis and hypodermis) capillary bleeding. Petechiae is a condition in which red spots of 1-2 mm appear on any part of the body.
