Kenza ganda

Third pakati zvirwere zvose kenza anotora kenza ganda. zvokurwara ichi kunoratidzwa kuvapo precancerous ezvinhu (zvirwere) zvakadai chirwere Paget waMwari, xeroderma pigmentosum, erythroplasia Queyrat, Bowen, chirwere uye penga nokuda kokuchembera kuchinja akadai: keratomas penga nokuda kokuchembera atrophy, keratoacanthoma.

Kazhinji, kenza ganda hwapedyo pashure kunotevera uye kupisa mavanga, lupus uye trophic maronda uye syphiloma.
Uyezve, etiologic chinhu kenza inotungamirwa zvinogona tinzwe Occupational exposures (kugara nemwaranzi, uyewo nevanhu zvibereko mafuta achinatsa, marasha uye mishonga siyana).

chirwere ichi nhaka ndiyo xeroderma pigmentosum chokuita akaderedza DNA kugadzira vanokwanisa, izvo zviri kukonzerwa yokuwana ultraviolet nemwaranzi.

Mumwe ngozi pachinhu kukura kenza ganda unoitisa kwazvo pigmented, flat, pamwe damerau contours nevi. The dhayamita neyokupedzisira, somunhu mutemo, ndizvo millimeters anopfuura matanhatu. Vamwe ngozi vari pigmented maronda nezviratidzo yebasa (magnification, kuvaviwa, tingling, nokutsva, shanduko pigmentation), zvakafanana boka iri vaiti dysplastic uye hofori nevi rwebhuruu.

Zvichienderana histological zvatariswa ndiwo anotevera mhando kenza ganda: muchitokisi basal, squamous, adnexal carcinoma, melanoma.

The chikuru Chikamu kenza zvose zvirwere ganda kutora zvakananga kenza uye melanoma (pamusoro makumi mapfumbamwe namatanhatu muzana zvose ganda kenza).

Ndezvipi zviratidzo kenza ganda? Squamous kunoratidzwa hyperkeratosis uye anopa nzira ganda atrophy. Kana atrophy ganda anotarira kupenyerera uye zvadaro ulcerate. Skin muenzaniso nokupera. Mujinga bundu iri chisimbiso palpable.

kenza Skin anooneka valikoobrazno akamutsa micheto, telangiectasias uye ulceration pamusoro pemvura. In zvinotevera ndizvo kuparadzwa ropa uye node midziyo, kukura oozing, ropa anooneka hyperemia.

Kuparadzwa ganda zvinoshandiswa - bvudzi follicles hungashaya vellus bvudzi. Melanoma rakasiyana pigmentation hunhu runobva uye sviba dzine seyokuti regression.

Dzakabudirira metastases kuonekwa nevanhu vose nekenza zviratidzo kudhaka.

Nechinangwa nechirwere akashandisa anobaya bvunzo (tichibvisa ane scalpel nebundu pamusoro) uye smears (nokuti ulcerated nzvimbo). Uyezve, sezvo yokuongororwa chisarudzo zvinoshanda zvachose biopsy.

Treatment kenza ganda rakakamurwa zvomusejari uye zvabatanidzwa. Ekupedzisira zvinosanganisira radiotherapy uye mishonga.

In kwokutanga nzendo kushandiswa rechirume uye kuvhiya kurapwa. Radiation kurapa uye mishonga inoshandiswa munzira generalized danho, hadzibatsiri.

Kudzivirira kenza ganda ndiko kudzivirira kukanganiswa migumisiro ultraviolet mwaranzi. Kuti adzivise kubviswa kenza ganda kushanda pamwe zvimwe idzodzo morphological kudzidza yokupedzisira.

Saka, kenza ganda harisi chete mutowo panguva, asiwo zvikuru ngozi panyaya kuvandudza metastasis uye dermal matambudziko.

Nokuda symptomatic vasabatwa (chirwere) kenza ganda hakuna kuoma. Maererano neizvi kashoma kuwana chimiro akazotevera nzendo metastasis. Kuziva melanoma achiri Danho kunokonzera unhu uye mukuru-mugiredhi pakurapa chirwere uye mberi zvakanaka fungidziro.
