Lichen Tropical

Lichen tropical: Description and characteristics

Tropical lichen (lat. l. tropicus) is one of the types of dermatitis lichenoid eczematous pigmentary skin disease. This skin condition is characterized by flat rashes that may be associated with sun exposure.

Also known as actinic lichen planus, New Guinean lichen planus or tropical lichen planus. Despite the variety of names, they all refer to the same pathology.

Tropical lichen usually appears as flat, reddish or brownish patches on the skin. These spots can come in various shapes and sizes, and their surface can be smooth or scaly. They usually do not cause pain, but can sometimes be accompanied by itching or burning.

The reasons for the development of tropical lichen are not fully understood, but it is believed that the main factor is exposure to ultraviolet (UV) rays from the sun on the skin. People living in tropical and subtropical climate zones are most susceptible to this disease due to the high intensity of solar radiation. However, tropical lichen can also occur in people living in other regions, especially with intense exposure to UV rays.

The diagnosis of tropical lichen is usually made based on physical examination and medical history. If necessary, your doctor may order additional tests, such as a skin biopsy, to rule out other possible causes of the rash.

Treatment for tropical lichen includes the use of topical medications such as creams or ointments with anti-inflammatory and antipruritic properties. It is also recommended to avoid prolonged exposure to direct sun and use sunscreens with high levels of UV protection.

In general, lichen is a common skin disease associated with sun exposure. Taking precautions and proper treatment will help reduce symptoms and prevent relapses of the disease. If you suspect that you have tropical lichen, it is recommended that you consult a dermatologist for an accurate diagnosis and appropriate treatment.
