Possible Causes
Generally, Red or purple spots on the skin can be related to:
A disease that causes inflammation and bleeding of small blood vessels, commonly affecting the skin, joints, intestines, and kidneys. This can lead to rashes, stomach pain, and kidney damage. Though it can affect anyone, it is more common in children under 10 years old. The cause is not well understood, but it may result from an immune system issue.
Immune thrombocytopenic purpura (ITP) happens when the immune system mistakenly attacks and destroys platelets, which are blood cells that help with clotting. ITP can cause low platelet levels, leading to easy bruising and bleeding. Triggers include infections like HIV and hepatitis.
Purpura Pigmentosa Progressiva, also known as Pigmented Purpuric Dermatosis or Schamberg's Disease, is a skin condition that presents with groups of small red dots inside the skin, usually on the arms and legs that can gradually become more orangish-brown. The exact cause is unknown, but it is caused by inflammation of tiny blood vessels in the skin called capillaries.
Related serious diseases
Sometimes, Red or purple spots on the skin may be related to these serious diseases:
The adrenal gland is an organ that releases hormones to control blood pressure and metabolism. In this condition, there are low hormone levels, and the causes include damage to the adrenal glands themselves or parts of the brain that control the adrenal gland. It can present with darkened areas of skin, extreme loss of body water, also known as dehydration, fatigue, weight loss that doesn't happen on purpose, nausea, vomiting or belly pain, lightheadedness or fainting, salt cravings, muscle or joint pains.
