pigmenttiläiskä

Pigmenttiläiskä is a Finnish term that translates to "pigment spot" or "pigmented lesion." It refers to any area of skin that is darker than the surrounding skin due to an increased concentration of melanin, the pigment responsible for skin color. These spots can vary widely in size, shape, color, and cause.

Common types of pigmenttiläiskä include nevi, more commonly known as moles. Moles are typically benign growths of melanocytes, the cells that produce melanin. Freckles, or ephelides, are small, usually tan or light brown spots that appear after sun exposure, particularly in fair-skinned individuals. Lentigines, often called age spots or liver spots, are also caused by sun exposure and are typically larger and darker than freckles, appearing on areas of the body frequently exposed to the sun, such as the face, hands, and shoulders.

Other causes of pigmenttiläiskä can include post-inflammatory hyperpigmentation, which occurs after skin injury or inflammation, such as acne or eczema, where the skin produces more melanin in the healing process. Hormonal changes, like those during pregnancy (melasma) or due to certain medications, can also lead to the development of pigmenttiläiskä.

While most pigmenttiläiskä are harmless, it is important to monitor them for any changes in size, shape, color, or texture, as these could be signs of skin cancer, particularly melanoma. Any concerning changes should be evaluated by a medical professional. Treatment for pigmenttiläiskä depends on the underlying cause and may include topical creams, chemical peels, laser therapy, or surgical removal.
