venous stasis<\/a> , diabetes, peripheral artery disease and vasculitis, are also often involved. Ulcers usually heal without leaving scars.<\/p>\n\n\n\nBubbles<\/strong> are filled with liquid, transparent, small bubbles of less than 10 millimeters in diameter. A bubble that is more than 10 millimeters in diameter is called a bulla. Herpes zoster (shingles), chickenpox, burns, allergic reactions and irritation form blisters and bullae.vesicle<\/p>\n\n\n\n <\/figure>\n\n\n\nIMAGE COURTESY OF THE PUBLIC HEALTH IMAGE LIBRARY OF THE CENTERS FOR DISEASE CONTROL AND PREVENTION.<\/p>\n\n\n\n
Wheals (hives, urticaria)<\/strong> are raised itchy red areas caused by swelling of the skin. They occur relatively suddenly and almost always disappear within 24 hours. Wheals are common allergic reactions to medicines, insect bites, or things that come in contact with the skin. If there are numerous wheals, one speaks of hives or urticaria.wheals<\/p>\n\n\n\n <\/figure>\n\n\n\nDR.’S PICTURE MED. THOMAS HABIF.<\/p>\n\n\n\n
Changes in skin color<\/h2>\n\n\n\n Redness of the skin<\/strong> (erythema) can occur in many diseases with inflammation or infection. Tumors on the skin are often pink or red. Abnormalities affecting blood vessels on the surface of the skin, such as fire stains , may appear red.<\/p>\n\n\n\nOrange skin<\/strong> is mostly due to hypercarotinemia. In hypercarotinemia, there is too much carotene (a pigment) in the blood, for example due to the excessive consumption of foods that contain a lot of beta-carotene (carrots).<\/p>\n\n\n\nYellow skin<\/strong> can occur in patients with jaundice . The causes of individual yellow areas are, for example, xanthelasmas and xanthomas (small yellowish fat deposits in the skin or tendons).Xanthelasma<\/p>\n\n\n\n <\/figure>\n\n\n\nDR.’S PICTURE MED.

Green fingernails<\/strong> are usually caused by infection with the bacterium Pseudomonas aeruginosa<\/em> .<\/p>\n\n\n\nPurple skin<\/strong> may be due to bleeding in the skin (cutaneous hemorrhage) or vasculitis . Overgrowth of blood vessels, such as Kaposi’s sarcoma and hemangioma , can appear purple. With skin inflammation due to dermatomyositis , a dark or purple rash (heliotrope rash) with reddish-purple swellings around the eyes can appear on the face.<\/p>\n\n\n\nBlue, silver, and greyish<\/strong> skin tones can result from the storage of medication or metals, including minocycline, amiodarone, and silver (argyria) in the skin. Skin with poor or no blood flow is purple to gray in color. Some birthmarks and birthmarks (nevi) that sit deep in the skin can look blue.<\/p>\n\n\n\nBlack skin<\/strong> lesions can contain special cells that produce the brown pigment melanin (melanocytes). Examples of these types of lesions are birthmarks (nevi) and melanomas . Thick, black, crusted scabs (scab) are accumulations of dead skin cells and can develop with dying tissue (infarction).HINWEIS:<\/strong> Dies ist die Ausgabe f\u00fcr Patienten. <\/p>\n","protected":false},"excerpt":{"rendered":"In medicine, certain terms are used to describe various skin spots and growths on the skin.\u00a0Some skin diseases and infections can lead to a change […]<\/a><\/p>\n<\/div>","protected":false},"author":1,"featured_media":115,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-107","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-articles"],"_links":{"self":[{"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/posts\/107","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/comments?post=107"}],"version-history":[{"count":3,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/posts\/107\/revisions"}],"predecessor-version":[{"id":130,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/posts\/107\/revisions\/130"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/media\/115"}],"wp:attachment":[{"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/media?parent=107"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/categories?post=107"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mostcommoncancer.net\/wp-json\/wp\/v2\/tags?post=107"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
