Dermatology - Spider Angioma
Spider angioma is a medical condition characterized by the presence of a red, spider-like lesion on the skin. Spider angiomas are a prevalent occurrence that can manifest at any age. They are more prevalent in females and may be linked to conditions characterized by high levels of estrogen, such as pregnancy (occurring in approximately two-thirds of pregnant women), estrogen therapy (e.g., oral contraceptives), or hepatocellular diseases like subacute and chronic viral hepatitis and alcoholic cirrhosis. Lesions that develop during childhood or pregnancy have the potential to naturally diminish over time. A crimson focal telangiectatic network of expanded capillaries, measuring up to 1.5 cm in diameter, extends outward from a central arteriole (punctum). The central raised spot is where the artery that supplies nutrients to the area is located, surrounded by blood vessels that spread out like branches. The lesion often appears as a single occurrence and is most commonly found on the face, forearms, and hands. During diascopy, the telangiectasia that radiates from the center becomes pale when pressure is applied, and the central arteriole may exhibit pulsation. The diagnosis is primarily based on clinical evaluation, and the possible conditions to consider are inherited hemorrhagic telangiectasia, ataxia-telangiectasia, or telangiectasia in systemic scleroderma. Spider angiomas are a non-cancerous abnormality of blood vessels. Laser therapy and electrosurgery are both efficacious for achieving desired cosmetic outcomes.
