Tinea Nigra: Definition, Symptoms, and Treatment
Tinea Nigra is an infection that attacks the upper layers of the skin. This is caused by a fungus called Hortaea werneckii. The fungus has also been named in the name of Phaeoannellomyces werneckii, Exophiala werneckii, and Cladosporium werneckii.
This fungus is found to break the soil, sewage, and vegetation of tropical or sub-tropical coastal areas. In particular, these areas include the coast of Caribbean and South America. Tinea nigra is rare in the United States, but when it is seen, it usually occurs in warm, humid climate in the southeast.
Fungus causes pain and brown legs to grow on palms and feet. Occasionally other areas of the body, such as neck and trunk, can be affected.
What Causes It?
Tinea nigra fungus stems from infection with Hortaea werneckii. Direct communication with fungus is necessary for transmission. For example, by shaking someone’s hand with Tinea nigra, the situation will not spread.
Fungus can infiltrate skin through open sores or cuts. It starts growing on wet, clammy, sweaty skin, this is the reason that the palms and feet soles of hands appear to be common goals for infection.
According to research in the online dermatology journal, lasers usually appear two to seven weeks after contact with the lungs. And when the situation can kill anyone, the journal Anais Brasileiros de Dermatologia reports that it is usually seen in women under the age of 20 years.
What are The Symptoms?
Tinea nigra is largely painless and harmless, but it produces some symptoms. they include:
• A brown or black patch looks like a stain that usually occurs on the palm of the hand or, rarely, on the sole of the foot. In a study published in Studies in Mycology, 22 out of 22 people had patches on their palms with Tinea nigra, while only three placed them on their feet.
• The patch is usually flat with defined boundaries.
• The darkest area of the patch is on the edges. Shading becomes lighter because it spreads internally. This dark outer area can look like Halo.
• The wound is slowing down and usually only appears on one hand or leg.
How is it Diagnosed?
Your doctor will take physical examination and will ask about your recent history along with your medical history.
Tinea nigra may look more like a serious skin condition, such as malignant melanoma, a deadly form of skin cancer that can present as a dark patch. Because of this, your doctor wants to scrape the wound sample and send it to the laboratory for testing. In some cases, the wound can be completely scraped and no further treatment is required.
Tinea nigra affects the upper layers of the skin. Because of this, it responds well to occasional plaster and cream. These medicines are applied directly to the skin.
Your doctor may recommend medicines such as alicylic acid, urea, or benzoic acid. This speed causes the cell business and skin to be restored. Antifungal creams is used for two to four weeks. In some cases, drying agents such as aluminum chloride are prescribed.
Since the fungus causing tinea nigra is found in soil, sewage and rot vegetable, the best way to prevent infection is to protect your skin. Wear shoes if you walk in warm, wet areas where fungi are found. If there is a risk then you will touch the vegetation – for example, if you hiking, gardening or planting – be sure to wear gloves.
Tinea Nigra is a rare and harmless skin condition. With treatment, it usually gets resolved in a few weeks. There is no permanent side effect and you are not likely to be empty until you return to the fungus again.
