Melanocytic nevushttps://en.wikipedia.org/wiki/Nevus
Melanocytic nevus imhando ye melanocytic nevus rine masero. Ruzhinji rweNevi runoonekwa mukati memakumi maviri emakore ekutanga ehupenyu hwemunhu. Neanenge mwana mumwechete pavana 100 vanoberekwa nevi. Nevi inowanikwa imhando ye benign neoplasm, nepo congenital nevi ichionekwa sediki malformation kana hamartoma uye inogona kunge iine panjodzi huru ye melanoma. Benign nevus inodenderedzwa kana kuti ovha uye kazhinji idiki (iri pakati pe1‑3 mm), asi mamwe anogona kunge akakura kupfuura saizi ye penzura eraser (5 mm). Vamwe nevi vane vhudzi.

○ Kurapwa
Kuvhiyiwa kwe laser kunowanzoitwa kubvisa nevi diki. Kana saizi yakakura kupfuura 4‑5 mm, kuvhiyiwa kunogona kudikanwa. Kuvana vadiki, nevus yakakura kupfuura 2 mm inowanzonetsa kubviswa zvachose pasina mavanga.

Congenital melanocytic nevus (CMN) is a melanocytic nevus that is either present at birth or appears during the latter stages of infancy. Nevus sebaceous has been described as the hamartomatous locus of an embryologically defective pilosebaceous unit. Here, we describe how we used the pinhole technique with an erbium-doped yttrium aluminium garnet (erbium : YAG) laser to treat nevi lesions in different patients.

A melanoma is a tumor produced by the malignant transformation of melanocytes. Melanocytes are derived from the neural crest; consequently, melanomas, although they usually occur on the skin, can arise in other locations where neural crest cells migrate, such as the gastrointestinal tract and brain. The five-year relative survival rate for patients with stage 0 melanoma is 97%, compared with about 10% for those with stage IV disease.
