Isifo sikaBowen: Ukuqonda i-Squamous Cell Carcinoma In Situ

Isifo sikaBowen sisimo sokuqala se-squamous cell carcinoma esihlala sikhawulelwe kwi-layer yangaphandle yesikhumba. Ukuqonda kunye nokuphatha kwangexesha kuvimba ukuphucuka kwe-mhlaza yesikhumba enobungozi.

Yintoni Isifo sikaBowen?

I-Bowen's disease, eyaziwa nangokuthi i-squamous cell carcinoma in situ, yimeko yesikhumba engaphambi kokuba ibe yicancer apho iicell ezingalunganga zikhona kwi-epidermis kodwa azikangenanga kwiingqimba ezijulile zesikhumba. Ibonisa umjikelo wokuqala we-squamous cell carcinoma (SCC) kwaye ngamanye amaxesha ichazwa njengokungena ngaphambi kokuba ibe yicancer yesikhumba. Le meko yachazwa okokuqala ngugqirha wesikhumba uJohn T.

Bowen ngo-1912 kwaye ibonwa kakhulu kubantu abaninzi abanesikhumba esifanelekileyo abangaphezulu kweminyaka engama-60. Ngelixa i-Bowen's disease ikhula kancinci kwaye ihlala kwi-epidermis iminyaka, ibamba umngcipheko ophakathi kwe-3 ukuya kwi-5 percent wokuphucuka ibe yi-squamous cell carcinoma uma ingaphathwanga.

I-Bowen's Disease ibonakala njani?

I-Bowen's disease ikhokelwa ngokubanzi njengephawu elichanekileyo, elibomvu okanye elipinki elinempumlo kwi-skin. Indawo ethintela ibonakala ikhululekile okanye ikhululekile kancinci kwaye ingahluka ngobungakanani ukusuka kwiimilimitha ezimbalwa ukuya kwiisentimitha ezininzi. Iphawu ingavela ibonakale njenge-crusty, flaky, okanye ikhululekile kancinci kumphunga, kwaye ayiphilanga okanye ayihambi yodwa.

Ibonwa ngokuxhaphakileyo kwiindawo ezixhaphakileyo elangeni ezifana neenyawo eziphantsi, iiforearms, intloko, kunye nomphakathi, kodwa ingavela naphi na emzimbeni kuquka neendawo ezingavulwanga elangeni. Ngokubhekisele kwiimeko ezixhaphakileyo zesikhumba ezifana ne-eczema, psoriasis, okanye iifungus, i-Bowen's disease ihlala ibonwa ngokungafanelekanga okanye iyagqithiselwa ixesha elide.!!

Izizathu kunye neMingcipheko

Imvelaphi ephambili ye-Bowen's disease kukuphazamiseka kwe-ultraviolet radiation okuqokelelweyo okuvela kwiminyaka yokuchaphazeleka elangeni. Abantu abaninzi abanesikhumba esifanelekileyo abachithe ixesha elininzi ngaphandle ngaphandle kokhuseleko olwaneleyo elangeni banemngcipheko ophezulu. Ukuchaphazeleka rhoqo kwi-arsenic, nokuba kukwimithombo yokuphuza engcolileyo, ukuxhumana emsebenzini, okanye ezinye iimeko, kuhlotshaniswa nokuphuhliswa kwe-Bowen's disease, ngamanye amaxesha ibonakala kwiminyaka emininzi emva kokuchaphazeleka kokuqala.

Ukuncitshiswa kwemiphumo ye-immune ngenxa yemithi yokuhambisa i-organ, i-chemotherapy, okanye iimeko ezifana ne-HIV kukhokelela ekwandeni kwemngcipheko. Iintlobo ezithile ze-human papillomavirus (HPV), ngakumbi iintlobo ze-HPV 16 kunye ne-18, zixhaphakile kwi-Bowen's disease kwiindawo ze-genital kunye ne-perianal. I-radiation therapy kwiindawo ezithile zesikhumba ingaphinde ibangele le meko.

Umngcipheko Wokuphucuka ube yiCancer Engeneleyo

Nangona i-Bowen's disease ihlala ibizwa ngokuba yimeko engaphambi kwe-cancer, ichazwa ngcono njenge-cancer kumjikelo wayo wokuqala kunye nolula. Iicell ezingalunganga sele zikhona kwi-cancer kodwa zihlala zikhawulelwe kwi-epidermis, engekho mthombo weegazi okanye i-lymphatic drainage, okuthetha ukuba ukwandiswa kwezinye iindawo zomzimba akukwazi kwenzeka kule meko. Ukuba ingaphathwanga, malunga ne-3 ukuya kwi-5 percent yeemeko ze-Bowen's disease ziya kuphucuka zibe yi-squamous cell carcinoma, apho iicell ze-cancer zifikelela kwi-basement membrane kwaye zingena kwi-dermis.!!

Nje ukuba kube nokungena, i-cancer ifumana ukufikelela kwiindawo zeegazi kunye ne-lymphatics kwaye inamandla okwandisa. Le yindlela abaqeqeshi besikhumba abacebisa ngayo ukuba kuphathwe i-Bowen's disease ngokukhawuleza kunokuba kulindwe.

Uhlolo

Uhlolo lwe-Bowen's disease luhlala luqala ngovavanyo lwekliniki olwenziwa ngugqirha wesikhumba obona iphawu elichanekileyo elibomvu, elinempumlo. I-Dermoscopy ingavula iindlela ezithile ezifana neegazi ze-glomerular ezihlelwe kwiiklas, ezisiza ukwahlula i-Bowen's disease kwezinye iimeko. Nokuba kunjalo, umgangatho ophakamileyo wokuhlola ngu-skin biopsy, apho umphunga omncinci wesikhumba esithintela ususwa kwaye ujongeka phantsi kwe-microscope.

I-biopsy ibonisa i-epidermal dysplasia epheleleyo eneenkqubo ezingalunganga kwi-epidermis kodwa i-basement membrane igcwele, iqinisekisa ukuba iicell ezingalunganga azikangenanga kwiingqimba ezijulile. Le confirmation ye-histological ibalulekile kuba iimeko ezininzi ezingenabungozi kunye nezingalunganga zingafana nokubukeka kwekliniki kwe-Bowen's disease.

Iindlela Zokuphatha

Iindlela ezininzi ezisebenzayo zikhona zokunyanga isifo sikaBowen, kwaye ukhetho luncike kubungakanani, indawo, kunye nenani lempawu kunye nempilo jikelele yomguli. Iindlela zokunyanga ezisetyenziselwa ukunceda njengekrem ye-5-fluorouracil okanye ikrem ye-imiquimod zifakwa ngqo kwi-lesion ngexesha elithile kwaye zisebenza ngokuchasa amaseli angalunganga ngelixa zigcina isikhumba esiqhelekileyo. I-cryotherapy, ebandakanya ukujolisa kwi-lesion ngamanzi e-nitrogen, yinkqubo esheshayo ehlinzekwa kwi-ofisi efanelekayo kwiindawo ezincinci.

I-Photodynamic therapy isebenzisa ikrem ethintela ukukhanya elandelwa kukuchaphazeleka kumgama ophakathi kokukhanya ukuze iphule amaseli angalunganga kwaye ikhululekile ngakumbi kwi-lesions ezinkulu. I-Curettage kunye ne-cautery ibandakanya ukuxhoma isikhumba esichaphazelekayo kwaye ivale umonakalo ngombane. Ukususa ngesandla kunganconywa kwi-lesions eziphikisana nezinye iindlela zokunyanga okanye apho kuqinisekiswa khona ukuba ukususwa kuphumelele ngokupheleleyo.

Ukuthintela kunye nokuJolisa

Ukuthintela isifo sikaBowen kugxile ekunciphiseni umonakalo owenzekayo ngenxa elanga ngokusebenzisa i-sunscreen ye-broad-spectrum, ukugqoka iimpahla ezikhuselayo kunye neephondo, kunye nokugwema ukujolisa elangeni ixesha elide ngexesha le-UV eliphezulu. Abantu abanembali yesifo sikaBowen kufuneka babe neziqinisekiso zonyango zexesha eliqhelekileyo kuba bahlala besengozini yokuphuhlisa ezinye iilesions kunye nezinye iifom ze-hud cancer. Ukujolisa ngenyanga kusiza ukufumanisa iindawo ezintsha okanye eziphindaphindayo kwangoko, kwaye nayiphi na indawo ebomvu okanye enesikhumba esiqhelekileyo engaphenduliyo kwi-moisturizers okanye kwiindlela zokunyanga ezisetyenziswayo kufuneka ihlolwe ngugqirha wezempilo. I-Skinscanner ingakunceda ukuba ujonge isikhumba sakho kwiilesions ezintsha okanye ezitshintshayo ngexesha, ukwenza kube lula ukufumanisa iimpawu zokuqala zeemeko ezifana nesifo sikaBowen kwaye ikukhuthaze ukuba ufune uvavanyo lwezempilo ngexesha.

Imibuzo ebuzwa rhoqo
