Step-by-step explanation:
Vascular lesion: refers to any abnormality in blood vessels, such as dilated or damaged vessels.
Cherry angioma: a small lesion on the skin with a red appearance, usually found in older adults.
Telangiectasia (spider angioma): a small lesion with an irregular border, often seen as a red mark with radiating blood vessels.
Petechia: small red or purple spots on the skin resulting from blood leakage from damaged vessels.
Ecchymosis: a larger brown spot on the skin, often with darker specks, caused by blood leaking under the skin due to injury.
Cicatrix: a scar that forms during the healing process of a wound.
Keloid: an abnormal overgrowth of scar tissue that is raised and extends beyond the original wound.
