The most common cause of petechiae is through physical trauma such as a hard bout of coughing, holding breath, vomiting, or crying, which can result in facial petechiae, especially around the eyes. Excessive scratching and friction, especially on thin and poorly circulated parts of the body may also cause petechiae.
Petechiae are seen on the chest, axilla, shoulder, and mouth. [5] Occulsion of dermal capillaries by the fat emboli result in petechial rash. Petechiae rash occurs in 50 to 60% of the cases. [7] Neurologic signs such as confusion, stupor, and coma may be present. These are usually temporary and do not happen on one side of the body.

Initially a vascular lesion is usually noted on the skin which can be firm and hard (indurated). Areas of tiny red dots (petechiae) can appear around the lesion or on other parts of the body. If the vascular lesion is internal, these petechiae and bruising can be seen on the skin. Bruising and spontaneous bleeding can also occur.
It is characterized by progressive lower extremity edema distal to the thigh, tight shiny skin, cyanosis (inadequate blood oxygenation), petechiae or purpura, and sudden severe pain of the affected limb in proportion to the level of venous blockage. Patients often have difficulty walking.
Petechiae which appear as on-off spots, then later become confluent, and appear as purpura (larger bruised areas, usually in dependent regions of the body). [citation needed] Oral, perioral, and acral paresthesias, tingling or 'pins and needles' sensation in and around the mouth and lips, and in the extremities of the hands and feet. This is ...
Glomerulations appear as checkerboard/lattice patterns, splotches, or pinpoint-sized red marks on the bladder. [7] [8] Glomerulations are classified into five grades that take into consideration the type and location of injury: Grade 0 (normal mucosa), Grade I (petechiae in at least two quadrants), Grade II (large submucosal bleeding), Grade III (diffuse global submucosal bleeding), and Grade ...
Functionally, the subcutaneous fat insulates the body, absorbs trauma, and serves as a reserve energy source. [14] Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails).
