ReferencesDysplastic nevus, ku wekî nevusek atypical an Clarks jî tê zanîn, di dermatolojî û dermatopatholojiyê de nîqaşan derxistîye holê. Bijîjk bi gelemperî van molan biyopsî dikin ji ber ku ew dikarin anormal xuya bikin û fikarên li ser melanoma zêde bikin.
A dysplastic nevus is also referred to as an atypical or Clarks nevus and has been the topic of much debate in the fields of dermatology and dermatopathology. It is an acquired mole demonstrating a unique clinical and histopathologic appearance that sets it apart from the common nevus. These moles appear atypical clinically, often with a fried-egg appearance, and are commonly biopsied by providers due to the concern for melanoma.

Dysplastic nevi, ku wekî nevi atypical an Clark jî tê zanîn, carinan dikare sedema melanoma bibe. Nêzîkî 36% ji melanomayan têne dîtin li ser neviyên dysplastîk. Nîşanên ku dibe ku nevusek dysplastîk veguheze bo melanoma, şekla nehevseng, guhertinên pigmentê yên zêde, an rengê gewr in. Ev pêşînî bi gelemperî di temenê piçûk de (dora nîvê salên sî) çêdibin, dikarin pirjimar bin, û bi gelemperî li ser stûnê ne. Ji hêla genetîkî ve, dysplastic nevi di navbera nevi û melanoma de ne. Lêbelê, tenê %20 heta %30ê melanomayan ji neviyên heyî têne çêkirin. Ji ber ku piraniya nevî ne di melanoma de dibe, bi gelemperî nayê pêşniyar kirin ku ew bi pêşî ve rakirin.
Dysplastic nevus, also called atypical or Clark nevus, can be precursor to melanoma, as the observation that 36% of melanomas have dysplastic nevi near the invasive tumor supports. Signs that a dysplastic nevus may have transitioned into a melanoma include asymmetry in contour, a noticeable increase in pigment variations, or a grayish tint indicating regression. These malignancies typically arise at a younger age (mid-thirties), are sometimes multiple, and are often found on the trunk. Molecularly, dysplastic nevi have a profile intermediate between benign nevi and malignant melanoma. While there is a recognized connection between dysplastic nevi and melanoma, it’s crucial to note that only about 20% to 30% of melanomas evolve from preexisting nevi. Given that the majority of dysplastic and typical nevi do not develop into melanoma, preventive removal of melanocytic nevi is not typically advised.

Melanoma celebek tumor e ku dema melanocît, hûcreyên ku ji rengê çermê berpirsiyar in, dibin kanser. Melanocytes ji qerta nervê çêdibin. Ev tê wateyê ku melanomas ne tenê li ser çermê, lê di heman demê de li deverên din ên ku hûcreyên qirka neuralî tê de koç dikin, mîna rêça gastrointestinal û mêjî jî dikarin pêşve bibin. Rêjeya zindîbûnê ji bo nexweşên bi melanoma li qonaxa destpêkê (qonaxa 0) 97% e, di heman demê de ji bo kesên ku bi nexweşiya qonaxa pêşkeftî (qonaxa IV) hatine teşhîs kirin, nêzî %10 e.
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.

Wekî ku di mirovên Kafkasyayî yên Dewletên Yekbûyî de tê dîtin, kesên ku neviyên dysplastîk hene, xetera melanoma ji %10 zêdetir e. Ji hêla din ve, yên ku nevusên dysplastîk nîn in, xetera pêşketina melanoma %1 kêm dibe.
○ Pêşniyara kesên ku neviyên dysplastîk hene
Xwe‑muayeneya çermê bi gelemperî ji bo pêşdîtina melanoma (bi nasîna neviyên atîpîkî yên ku dikarin rakirin) an jî ji bo dîtina zû ya tumorên heyî pêşniyar dike. Kesên ku dîroka kesane an malbatî ya pêşveçûna çermê an pir neviyên atîpîkî hene, divê her salê carekê bi dermatologê re bibînin da ku ew bi melanoma re neberin.
Kurtenivîsa [ABCDE] ji bo alîkariya pêşkêşkarên lênihêrîna tenduristî û kesên ku dixwazin taybetmendiyên sereke yên melanoma bifikirin, bikar tê. Lê herwiha, gelek keratozên seborrheîk, lentigo senilis, û şûjînên din jî dikarin taybetmendiyên [ABCDE] nîşan biden, û nekarin ji melanoma ve cûda bibin.
○ [ABCDE]
Asymmetrical: Birîna çermê asimetrîk.
Border: Sînorê birînê ne normal e.
Color: Melanoma bi gelemperî gelek rengên nerêkûpêk hene.
Diameter: Neviyên ku mezintirî 6 mm in, riskê melanoma zêde dikin.
Evolution: Guherîn (pêşveçûn) ya nevus an birînê dikare nîşan bide ku birîn xerab dibe.
