Iiseli eziqulethe ingxube ephezulu ye-melanin ayiyi-yocytes. Ukuqokelela kwabo kubangela ukubunjwa kwe-mole, ebizwa ngeyeza kuthiwa yi-pigment nevus. Kuthathwa njengesilonda esikhulayo kwaye kaninzi ayibangeli iingxaki, nangona ezinye iiprospecies of pathology zandisa ingozi ye- melanoma .
I-pigment okanye i-melanocytic nevus - ibangela
Zonke izinto ezibangela ukudibanisa kwindawo enye ye-non-yocytes ayengakabekwa. Kuphela oku kwaziwa:
- izifo zofuzo;
- utshintsho kwesikhumba somntwana ngenxa yokutshatyalaliswa komzimba womama we-radiation okanye i-toxic;
- usulelo lwe-excretory ne-genitourinary sphere;
- ukuguquka okubukhali kwemvelaphi ye-hormonal.
Kukho iintlobo ezininzi zezifo, eziqhelekileyo zazo ziya kuxutyushwa ngezantsi.
Iingubo ezinkulu ze-pigment ne-skin
Uhlobo lwe-pathology olubhekisiwe lubangelwa ubukhulu be-neoplasm - ukususela kwi-20 cm. Le ntsholongwane yesifo sokuzalwa kunye nokuhlala emzimbeni wobomi.
Iimpawu:
- indawo enkulu kwesikhumba sombala omnyama okanye omnyama;
- ukunyuka kancane kwe-epidermis kwingingqi yokuqokelela kweengcuka;
- ukwandisa i-pigmentation;
- utshintsho kwisakhiwo sesikhumba, ukubonakala kwezitenxo, isifo sofuba;
- ukwanda kweenwele kwiindawo ezikhuselweyo;
- ukwandiswa ngobukhulu besisu.
Kubalulekile ukuba uqaphele ukuba, ngenxa yemonakalo eyahlukeneyo kwi-nevus, ingakhokelela ekuphuhlisweni kwe-melanoma. Ngako oko, indlela efanelekileyo yokugwema imiphumo emibi ithathwa njengothutho lokukhangela. Xa kungenakwenzeka ukwenza umsebenzi, isigulane kufuneka sihambele i-oncologist kunye nesidemologist yokuvavanya iimviwo ubuncinane kanye ngonyaka.
Intradermal ivolmentary nevus
Phakathi kwabantu abaqhelekileyo, olu hlobo lwesifo lubizwa ngokuba yi-birthmark. Inokufumaneka kwindawo yomibini kwesikhumba kunye nakwiimpawu ezinamaqabunga.
Njengomthetho, i-intradermal nevus ayibangeli nayiphi na ingxaki. Unyango alufunanga, kuba i-birthmark ayizange ibe yimbangela yomhlaza wesikhumba .
Umgca wee-pigmentary nevus
Indlela echazwe ngayo ye-pathology ifumaneka ngokuqhelekileyo kwiinyawo, iintendelezo kunye nezitho zangasese. I-neoplasm isoloko encinci, ingabi ngaphezu kwe-1 cm, ubukhulu obungabonakali bukhulu (ukuya kuma-50 mm).
Isici esibonisa umda we-nevus kukungabikho kweenwele endaweni yalo. I-mole ibukeka kwintonga ephothiweyo yombala omnyama okanye omnyama.
Ngenxa yokuba umngcipheko ophezulu wokuguqulwa kwesi sifo kwi-melanoma enobungozi, i-neoplasm kufuneka isuswe ngokukhawuleza nge-laser coagulation okanye ukuhlinzwa.
Vigmentary papillomatous nevus
Ubonakala obunobunzima besi sifo bunkulu (ukuya kutsho kwi-4 cm) kwaye luhlala luhlala entanyeni, nje emva kwendlela yokukhula kweenwele okanye entloko.
Imfundo ifana ne-papilloma, iimpawu eziphawulekayo zimbombo ezingalinganiyo, ukuphakama okubonakalayo ngaphezu kwezinga le-epidermis enempilo kunye nombala omnyama. Kwi-nevus enjalo, iinwele ezimnyama ezinzima zihlala zikhula.
Nangona ukhuseleko lwefayili ye-pathology, kucetyiswa ukuba unyango, ekubeni
I-pigmentary nevus yelihlo
Olu qo kelelo lweeseli ezinama-melanocytic luhlala kwindawo yokudibanisa phakathi kwe-cornea kunye ne-sclera. Ingaba nobubanzi obukhulu kunye nombala ohlukileyo.
I-Conjunctival nevus ibolekisa kuphela unyango ojongene nokunyangwa, ukuba i-ophthalmologist iyimfuneko emva kokuluhlu lwee-laboratory.
