Red spots on the skin
Many times it happens to notice one or more red spots on our skin. The question we all ask ourselves is whether these spots are dangerous or not for our health, and whether they constitute a temporary or permanent problem.
First we need to clarify how many and what types of skin lesions that can appear on our body.
THE types of skin lesions red most frequent skin types are the following:
- There stain or macula, is a change in the color of the skin that does not disappear when pressing the skin. It can be of various colors based on the amount of melanin it contains, e it is not in relief, so when you run a finger over it, you don't hear anything. This is the real stain. The types of red spots more frequent are:
- Angiomas: are mostly benign neoformations, due to
abnormal cellular development of blood or lymphatic vessels. They are often commonly referred to as "birthmarks" and can cover a large area of the body. In particular, a typical red skin spot of the angiomatous type is theruby angioma or cherry angioma, characterized by its bright red color. Angiomas are not malignant lesions, in any case, however, it is always good that they are seen by a doctor at least at the first finding.
- Angiomas: are mostly benign neoformations, due to
- Chloasma: also called melasma, which is a skin spot characterized byhypermelanosis, that is, from the excessive production and accumulation of melanin on the skin. Melanin is a pigment derived from melanocytes that serves to darken the skin to protect itself from the sun's rays. In chloasma we will have a browning of the skin, occurs above during pregnancy, or while using a contraceptive pill.
- Hemangiomas: they are benign tumors of the endothelial cells, they are lesions that cover the vascular structures and are very frequent. The hemangiomas in particular they constitute vascular tumors more frequent in children. They are divided into congenital hemangiomas, which can be rapidly involutionary, non-involutionary or partially involutionary, and in infantile hemangiomas. Hemangioma also differs based on its physical characteristics, being multiple or single (isolated hemangioma), deep, superficial or combined. Some hemangiomas, larger in size and irregular in shape, are called segmental hemangiomas. Other hemangiomas take on less benign features, such as the tuffed hemangioma and thekaposiform hemangioendothelioma, with completely different problems than the previous ones.
- Bruising, they are secondary to contusions against other objects, they emerge following a superficial blood extravasation.
- Hematomas, they are like bruises but blood shedding affects the deep layers of the skin.
- Erythema, is a type of red spot of the skin which is due to arterial (active) vasodilation, or venous (passive) vasodilation of the blood vessels in the skin. Unlike macules when pressing on the erythematous skin, the redness disappears. Typical erythema are
- Rashes occurring in children, they are those of childhood exanthematous diseases such as measles, scarlet fever, rubella, and exanthema subitum or sixth disease.
- Sunburn, that is the classic sunburn with redness of the skin associated with itching and, at times, with the formation of blisters after prolonged and exaggerated sun exposure.
- Erythema from adverse drug reactions.
- Wheal (wheal), is a small, firm-textured lump of skin usually accompanied by a intense itching, Red. The wheal is due to the presence of vasodilation and edema of the skin, and is the typical skin spot that appears during a allergic reaction in the so-called urticaria. The wheal is also called an urticarial lesion. Red spots on the skin detected with respect to the surrounding skin, strongly itchy and arisen in a short time are therefore often secondary wheals a hives.
- Vesicle it is a skin lesion raised with respect to the surrounding skin but, unlike the wheal, it is of liquid consistency. The vesicle is in fact a small cavity of usually size less than one centimeter, the content of which can be serous or blood. Blisters are the typical skin lesions that appear in the course of chickenpox or in its relapse (shingles or herpes zoster), in dermatitis eczematous and incold sores and genital herpes.
- Bubble: it is a liquid-filled skin relief similar to the vesicle but larger than the cemtimeter. It is the typical lesion of the vulgar pemphigus (serous bubble), while the bullous pemphigoid it is characterized by erythematous-like blisters that often contain blood.
- Flittene: flittene is a serous fluid-filled skin lesion that develops after contact with physical agents, such as hot or cold relevant, or after contact with chemical substances. The flittene is the typical skin lesion that develops following a burn.
- Pustule, it is a raised and erythematous alteration of the skin, which is typical of diseases such as acne, there furunculosis is impetigo. The pustule is often filled with pus.
- Papule: the papule is a lesion solid reddish of the skin, and is caused by cell proliferation or inflammatory infiltration secondary to insults such as exanthematous diseases of childhood or le insect bites. The papule is small, usually less than 0.5 cm.
- Plate. Plaque is a lesion of similar characteristics to those of the papule, that is, one superficial solid lesion, but it differs from the papule by its own dimensions greater than half cm. The disease par excellence in which widespread plaques are found is the psoriasis. Please note: sometimes many nearby papules merge, giving rise to a plaque.
- Nodule. The nodule is a solid lesion, raised with respect to the surrounding skin, larger than half a centimeter, caused by the infiltration of the deep layers of the skin. The nodule is a typical lesion of many often malignant diseases which can be the basalioma cutaneous, the melanoma, the carcinoma cutaneous. Other well-known diseases that give diffuse nodules are the sarcoidosis and erythema nodosum, which give hard and thick lumps on palpation painful.
