Kankere ea letlalo

Ea boraro har'a mafu kaofela bakeng sa kankere nka kankere ea letlalo. bolwetse ena e tšoauoa ka ho ba teng ha ea maemo precancerous (mafu) kang lefu Paget e, xeroderma pigmentosum, erythroplasia Queyrat, lefu Bowen, 'me liphetoho senile tse kang: keratomas senile felloa ke matla, keratoacanthoma.

Hangata, kankere ea letlalo develops ka mor'a ho sithabela le ho chesa maqeba, lupus le liso tsa ka maleng trophic le syphiloma.
Ho phaella moo, etiologic Ntlha e ka sebopeho bakeng sa kankere ka tshusumetso exposures mosebetsing (pepesehela mahlaseli a kotsi, hammoho le ho kopana le lihlahisoa tsa oli e hloekisoa, mashala le lik'hemik'hale tse fapa-fapaneng).

lefu lena lefa ke xeroderma pigmentosum amanang le fokoletse theko ea DNA lokisa bokgoni, e bakoang ke ho pepesehela mahlaseli mahlaseli.

A kotsi itseng mabapi le tsoelo-pele ea kankere ea letlalo baka ka matla haholo pigmented, bataletseng, ka lerotho contour nevi. The bophara oa bobeli, e le busa, e millimeters tse fetang tse tšeletseng. Itseng kotsi ke pigmented diso ka lipontšo tsa mosebetsi (magnification, ho hlohlona, tingling, tukang, phetoho ka pigmentation), sehlopha se tšoanang e ngotsoe dysplastic le seqhenqha putsoa nevi.

Ho itšetlehile ka litšobotsi histological tse latelang mefuta oa kankere ea letlalo: basal seleng, squamous, adnexal carcinoma, melanoma.

Karolo e khōlō ho tsohle bakeng sa kankere le mafu a letlalo nka ka ho toba le kankere le melanoma (ho fihlela ka mashome a robong a metso e tšeletseng ba lekholo ba kankere eohle ea letlalo).

ke matšoao a kankere ea letlalo ke efe? Squamous talima ka eona hyperkeratosis le fana ka tsela ea ho letlalo felloa ke matla. Ha felloa ke matla a letlalo shebahala benyang le ile ulcerate. Letlalo paterone ke disappears. E ka tlaase ea hlahala e palpable tiiso.

kankere ea letlalo le hlaha ka valikoobrazno tsosoa metshetshe telangiectasias le ulceration ka holim'a metsi. Ka e latelang ke ho timetsoa ha mali le lijana lisele tsa mmele, ho ntshetsa pele oozing, mali bonahala hyperemia.

Timetso ea appendages letlalo - moriri follicles le ka haelloa ke vellus moriri. Melanoma e fapaneng pigmentation bath ea libakeng lintoeng le bohlasoa ho tloha bofokoli.

Ntshetswa metastases hlaha ho tloaelehile hore ho tsohle kankere matšoao a botahoa.

Ka morero oa ho fumanoe sebelisoa prick teko (fala ka holim'a scalpel hlahala) le smears (bakeng sa libaka ulcerated). Ho feta moo, ka khetho tekotshupo e sebetsa palo yohle biopsy.

Phekolo ea kankere ea letlalo e arotsoe ho buoa le ho kopantswe. Ea bobeli ho akarelletsa ho radiotherapy le chemotherapy.

Ka mekhahlelo ea pele ea sebelisoa ho kopantswe le kalafo ho buoa. Mahlaseli phekolo le phekolo ea lik'hemik'hale tse sebelisoang ka sethaleng generalized, na thuso.

Thibelo ke kankere ea letlalo ke ho sireletsa khahlanong le liphello tse bohloko tsa mahlaseli mahlaseli. E le hore ho thibela ho tlosa kankere ea letlalo-sebetsa le lihlopha ka ho eketsehileng ho ithuta morphological ea bobeli.

Kahoo, kankere ea letlalo hase feela boemo bo neng li tloaelehile ka nako eo, empa hape e kotsi haholo ya ka dipehelo tsa tsoelo-pele ea metastasis le dermal mathata.

Ka lebaka bontshang matshwao bonoa (fumanoe) oa kankere ea letlalo Hase ntho e thata. Mabapi le sena sa tloaelehang ho fumana mofuta o ka mekhahlelo e hamorao ba metastasis. Boitsebiso ba melanoma a sa le sethaleng, mathoasong a etsa hore boleng bo le phahameng sehlopheng kalafo ea lefu lena le le ka ho eketsehileng e itse'ng tšoanelang.
