Which condition involves small red or purple spots on the skin due to intradermal hemorrhage?

1. Photophobia

2. Photosensitivity

3. Petechiae

4. Postural Hypotension

The correct answer is: Petechiae

The condition that is associated with small red or purple spots on the skin due to intradermal hemorrhage is petechiae. These spots occur when tiny blood vessels called capillaries bleed, resulting in the characteristic pinpoint-sized red or purple marks on the skin and other surfaces. Petechiae can arise from a variety of underlying causes, including trauma, certain medical conditions, and blood clotting disorders. Photophobia and photosensitivity refer to sensitivity to light, often linked to ocular conditions, but do not involve skin lesions. Postural hypotension, on the other hand, refers to a drop in blood pressure upon standing, which can cause dizziness or fainting, but does not relate to the skin manifestations like petechiae do. Therefore, understanding the specific characteristics of petechiae is crucial for recognizing its clinical significance in medical practice.
