<\/span>What is the cause of the lip melanotic macula?<\/span><\/h2>\nA melanotic lip macula is believed to be caused by sun exposure, and is more common in fair-skinned people. However, it can also occur in dark-skinned individuals and, as described above, similar lesions can arise in places that are never exposed to the sun. Fortunately, melanotic macules are harmless.<\/p>\n
<\/span>What other conditions cause lip? pigmentation<\/span>?<\/span><\/h2>\nA melanotic lip macula can be confused with another pigmented skin lesion.<\/p>\n
\n- Freckles (ephelides)<\/li>\n
- Lentigo simplex<\/li>\n
- Lentigo solar<\/li>\n
- Venous<\/span> hemangioma<\/span> (venous lake)<\/li>\n
- Amalgam tattoo<\/li>\n
- Union melanocytic<\/span> nevus<\/span> (a flat mole)<\/li>\n
- Lentigo maligna (a form of melanoma in the place<\/span>)<\/li>\n
- Superficial spreading melanoma.<\/li>\n<\/ul>\n
These conditions can be differentiated<\/span> of lip melanotic macula due to a combination of clinical and histological<\/span> features.<\/p>\nMultiple injuries can be a sign<\/span> of a extended<\/span> skin condition, such as:<\/p>\n\n- Peutz Jeghers syndrome<\/span><\/li>\n
- Addison's disease<\/li>\n
- Laugier-Hunziker syndrome<\/li>\n
- Multiple lentiginosis (various syndromes, including Noonan syndrome with multiple lentigines<\/span>)<\/li>\n<\/ul>\n
<\/span>What research should be done?<\/span><\/h2>\nA melanotic lip macula has a characteristic pattern when examined with a magnifying glass or by dermoscopy. Lesions with a typical history and appearance do not require a biopsy.<\/p>\n
If a skin biopsy<\/span> is performed because the lesion is changing or looks irregular, a melanotic lip macula shows the following characteristics in dermatopathology<\/span>:<\/p>\n\n- Increased melanin<\/span> at melanocytes<\/span> and keratinocytes<\/span> of the basal<\/span> cap<\/span><\/li>\n
- Melanophages<\/span> at dermal<\/span> papillae<\/span>, which indicates pigmentary incontinence<\/li>\n
- Mild acanthosis<\/span> without lengthening the challenge<\/span> ridges<\/li>\n<\/ul>\n
Nuclear<\/span> atypia<\/span> is absent and the melanocyte<\/span> The count is normal.<\/p>\n\n

<\/span>What is the treatment of lip melanotic macula?<\/span><\/h2>\nTypical injuries can be observed. Suspicious injuries, including injuries they show progressive<\/span> instead, a biopsy should be done.<\/p>\nIf treatment is requested, the macules can be frozen (cryotherapy<\/span>) or removed using a To be<\/span> or intense pulsed light. Excision<\/span> can also be done but will leave a scar<\/span>.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":" \u00bfQu\u00e9 es un melan\u00f3tico labial? m\u00e1cula?
