Tinea Nigra is a superficial fungal infection that primarily affects the skin. It is characterized by dark, pigmented patches, typically on the palms of the hands or soles of the feet. The condition is caused by the fungus Hortaea werneckii.

Causes

Tinea Nigra is caused by the fungus Hortaea werneckii. This fungus is found in soil, sewage, and decomposing vegetation. It is not highly contagious and is usually contracted through direct contact with the fungus in its natural habitat or from contaminated objects.

Symptoms

The primary symptom of Tinea Nigra is the appearance of a dark, pigmented patch on the skin. This patch is usually brown or black in color and can be mistaken for a stain or bruise. The patch is typically flat and smooth, with a clearly defined border. It is most commonly found on the palms of the hands or soles of the feet.

Diagnosis

Diagnosis of Tinea Nigra is typically made through a physical examination and a review of the patient's medical history. A KOH test may be performed, in which a sample of the affected skin is treated with potassium hydroxide and examined under a microscope. This test can reveal the presence of the Hortaea werneckii fungus.

Treatment

Treatment for Tinea Nigra typically involves the use of topical antifungal medications. These medications are applied directly to the affected area and work by killing the fungus. In most cases, the pigmented patch will begin to fade within a few weeks of starting treatment.

Prevention

Prevention of Tinea Nigra involves avoiding contact with the Hortaea werneckii fungus. This can be achieved by wearing protective clothing when in environments where the fungus is likely to be found, such as soil or decomposing vegetation.
