What are skin lesions?

Skin lesion is a skin stain that contrasts with the surrounding tissue due to differences in texture, thickness and pigment. From the Latin root of cutis , which means that the skin, skin lesions are superficial and can be rough, smooth, leather or raised. They are often characterized as a visual warning sign for human immunodeficiency virus (HIV) because it appears to be one of its earliest symptoms. They are also evidence of skin cancer and skin infections such as worm, rosacea and lichen. Skin lesions, however, can appear harmlessly on newborns as simple maternal features.

There are specific types of skin lesions that are distinguished by their composition. Some lesions are made of lipoproteins and are referred to as "asteroid bodies". Phosphate, iron and calcium carbonate form another set of lesions referred to as "Schaumann bodies". The residual bodies are composed of lipomukoprotein granules.

Location of skin lesions can bridge the whole body, especially whenThey are the result of systemic diseases such as lupus. Face, scalp, back and arms are usually areas in which lesions are formed; They can occur in multiples or as a singular lesion that grows and spreads. Some people suffer from lesions on their feet and hands. The presence of lesions on the scalp can often lead to located hair loss. Mycobacterium tuberculosis can cause lesions on the penis, even if they are rare.

cancer tumors can begin as skin lesions and are often incorrectly diagnosed as mere skin infections. Medical reports show that some patients suspected of their lesions have found that they had lymphoma after lesions were biopsies. Early treatment of malignant lesions can be successful and prevent the spread of cancer to the lymph nodes and throughout the body, say doctors.

lesion from non-hodgkin's lymphoma is the most commonly observed in HIV and PAC victimsIENTs with acquired immunodeficiency disease (AIDS). Other HIV -related lesions are caused by herpes and tuberculosis. They can be treated with antiviral drugs.

sarcoidosis, a disease affecting lungs, eyes and lymph nodes, can manifest itself as a skin lesion in at least 20 percent of people with this disease. These purple lesions are often the only early effects of this disease that eventually spreads behind the skin to body tissues. The nose and scalp are the most common areas in which lesions associated with sarcoidosis can be found.

treatment of skin lesions includes antibiotics, methotrexate and griseofulvin used orally. Radiation is an alternative option. Some skin lesions cannot be cured, but steroid drugs applied locally may be alleviated. Dermatologists can also use retinoids and immunosuppressants to stop lesions. Occasionally the presence of the disfiguring Lesion can be surgically removed; Once skin lesions are removed or cured, they can be behind.
