Amaseli aqukethe i-melanin ephezulu ayiyona i-coyte. Ukuqongelela kwabo kuholela ekwakheni imvukuzane, okuyimithi ebizwa ngokuthi i-pigment nevus. Kubhekwa njengesihluthulelo sesikhumba esibi futhi kaningi akubangeli izinkinga, nakuba ezinye izifo ezincane ze-pathology zandisa ingozi ye- melanoma .
I-pigment noma i-melanocytic nevus - izimbangela
Zonke izimbangela ezibangela ukungqubuzana endaweni eyodwa yama-non-oktote azange zisungulwe. Kuphela okulandelayo okuyaziwa:
- izifo zofuzo;
- izinguquko esikhumbeni se-fetal ngenxa yokuvezwa emzimbeni kamama wemisebe noma i-toxic;

Kunezinhlobo eziningana zezifo, okuvame kakhulu kuzoxoxwa ngezansi.
Ukugqwala okukhulu kunamahloni esikhumba
Uhlobo lwe-pathology olucatshangelwayo lubangelwa ubukhulu be-neoplasm - kusuka ku-20 cm. Lokhu kuphazamiseka yisifo sofuba futhi kuhlala emzimbeni wokuphila.
Izimpawu:
- indawo enkulu esikhumbeni sombala omnyama noma omnyama;

- ukwanda kwezinwele endaweni yesikhumba esithintekile;
- ukwanda ngobukhulu besisu.
Kufanele kuqaphele ukuthi, ngenxa yemonakalo eyahlukene kwi-nevus, ingaholela ekuthuthukiseni kwe-melanoma. Ngakho-ke, indlela engcono kakhulu yokugwema imiphumela emibi kubhekwa njengokususwa kokuhlinzwa. Uma kungenakwenzeka ukwenza lo msebenzi, isiguli kufanele sivakashele i-oncologist ne-dermatologist ukuze kuhlolwe izivivinyo okungenani kanye ngonyaka.
I-intradermal ivolmentary nevus
Phakathi kwabantu abavamile, lolu hlobo lwe-pathology lubizwa ngokuthi i-birthmark. Ingaba khona kokubili kwesikhumba nasemagqumeni amancane.
Njengomthetho, i-nevradermal nevus ayibangeli noma yikuphi ukuphazamiseka. Ukwelashwa akudingeki, ngoba i-birthmark ayilokothi ibangele umdlavuza wesikhumba .
I-border border nevus
Indlela echazwe ngayo ye-pathology iyatholakala kaningi ezinyaweni, izintende zezitho zomzimba nezitho zangasese. I-neoplasm ngokuvamile encane, engaphezu kuka-1 cm, ubukhulu obungavamile kakhulu obukhulu (kuze kube ngu-50 mm).
Isici esivela emngceleni we-nevus ukungabikho kwezinwele endaweni yendawo. I-molecule ine-nodule yama-flat of black brown noma umbala omnyama.
Njengoba kunikezwa ingozi enkulu yokuguqulwa kwalolu hlobo lwesifo zibe yi-melanoma ebulalayo, i-neoplasm kufanele isuswe ngokushesha ngangokunokwenzeka nge-laser coagulation noma ukuhlinzwa.
I-nevus ye-papillomatous ye-pigmentary
Ukubukeka kwesifo lesi sifo kukhulu kakhulu (kufikela ku-4 cm) futhi kuvame ukutholakala entanyeni, ngemuva kwesigcawu sokukhula kwezinwele noma ekhanda.
Imfundo ifana ne-papilloma, izici zesici yizingqikithi ezingafani, ukuphakama okubonakalayo ngaphezu kwe-epidermis enempilo nombala omnyama. Ezimvini ezinjalo, izinwele ezimnyama ezinzima zivame ukukhula.
Naphezu kokuphepha kohlobo lwe-papillomatous of the pathology, kunconywa ukuthi uyiphathe ngokuhlinzwa, ngenxa yokuzibandakanya
I-pigmentary nevus yeso
Lokhu kuqoqwa kwamangqamuzana e-melanocytic kutholakala endaweni yokuxhumana phakathi kwe-cornea ne-sclera. Kungaba nobubanzi obukhulu nombala ohlukile.
I-conjunctival nevus ikhokhela kuphela ekwelapheni okuhlinzekwa, okumele kubekwe yi-ophthalmologist ngemva kochungechunge lwezifundo ze-laboratory.
