Indawo yaseMongolia esanda kuzalwa: izizathu, ukwelashwa

Ezinye izingane ngokushesha ngemva kokuzalwa zithola ukuthi zinendawo yaseMongolia. Kuyini? Indawo yaseMongolia i- pigmentation yesikhumba, esinomumo ongavamile noma ohlangene kanye ne-gray-blue hue. Ngokuvamile, lokhu kwenzeka endaweni yangasese ye-lumbosacral. Eqinisweni, ukuguqulwa kwemibala kuyisifo esingenayo. Lapho uthola i-neoplasm, ukunakwa okukhethekile kunikezwa ukuhlukaniswa kwawo ne-melanoma-eyingozi. Njengomkhuba wokubonisa, indawo yaseMongolia iyanyamalala ngokuzimela ngemva kweminyaka engu-4-5.

Kungani kuthiwa kanjalo

Kungani lokhu kuhlobisa kungabi lutho kodwa "indawo yaseMongolia"? Ngempela, iyini imfihlo? Iqiniso liwukuthi amaphesenti angama-90% wabantwana besizwe samaMongoloid bazalwa benomfanekiso onjalo. Ezingcupheni yi-Ainu, Eskimos, amaNdiya, ama-Indonesia, amaJapane, amaKorea, amaShayina nesiVietnam. Futhi, indawo yaseMongolia ivame ukuvela ezincane ezisemncintiswaneni weNegroid. Ngokuqondene nabantu baseCaucasus, izidakamizwa ezinjalo zikhona emzimbeni kuphela ku-1% kwezinsana ezisanda kuzalwa.

Indawo yaseMongolia ivame ukuhlala e-sacrum. Kunezinhlobo eziningi zamagama ezinjalo zokugquma. Ngokuvamile ine "indawo engcwele".

Izici zesifo

Kungani indawo yaseMongolia ivela entsheni? Isikhumba sihlanganisa izigaba eziningana ezixhunyiwe: i-dermis ne-epidermis. I-pigmentation incike ukuthi amangaki amangqamuzana akhethekile esikhumbeni somuntu, kanye nomsebenzi wabo. Ama-melanocytes atholakale e-epidermis futhi akhiqize i-pigment. Nguye othinta umthunzi wesikhumba.

Njengoba izifundo zibonisa, i-1 mm ^{2 ye-} epidermis ayikho ama-melanocyte angaphezu kuka-2000. Inombolo yabo yi-10 kuphela kuphela yezingqikithi zamaseli. Nokho, umthunzi wesikhumba uthintwa umsebenzi osebenzayo wama-melanocytes. Izinhlobo ezihlukahlukene zokuphazamiseka emisebenzini yamaseli anjalo zingabangela ukuthuthukiswa kwezifo ezinjenge-halonews, i-vitiligo njalonjalo.

Ngokuqondene nabantu abanesikhumba esimhlophe, i-melanin emzimbeni wabo ikhiqizwa kakhulu. Ngokuvamile lokhu kwenzeka kuphela ngaphansi kwethonya elangeni. Ngenxa yalokho, isikhumba sigcwele ukushisa kwelanga. Kumuntu womhlanga omnyama noma ophuzi i-melanin ikhiqizwa njalo. Yingakho isikhumba sigcina futhi sithola umthunzi onjalo.

Izimbangela zokugqoka

Indawo yaseMongolia esanda kuzalwa ayibonakali ngesikhathi sokuzalwa. Ngesikhathi i-embryo iqala esibelethweni, ama-melanocytes asuka e-epidermis evela ectoderm. Ngokusho kososayensi, indawo yaseMongolia yakhiwa ngenxa yenqubo engaphelele yokuhambisa amangqamuzana nge-pigment. Ngamanye amazwi, emva kokuzalwa kwengane, ama-melanocytes ahlala emdemeni. I-pigment, ekhishwa lawa maseli, futhi ibangela ushintsho embala wesikhumba. Esikhumbeni somntwana ngenxa yalesi senzakalo kubonakala indawo, ene-gray hue.

Ososayensi bafinyelela esiphethweni sokuthi indawo yaseMongolia ivela ngenxa yokukhubazeka okuncane kokuthuthukiswa kwe-embryonic, okubangelwa ukuba khona emzimbeni wesisu sofuzo olukhethekile.

Isithombe esitholakala emitholampilo yokuguqulwa kwesisu

Indawo yaseMongolia, isithombe esinikezwa kulesi sihloko, sakhiwe esifundeni se-sacrum futhi sibheke njengento ephazamisayo ngaphandle. Thatha lokhu kuhlobisa kwesigaba se-nevi esandulela. Ngokuvame ukuthi indawo inombala ohlaza okwesibhakabhaka, kodwa kwezinye izimo ingathola umbala ohlaza okwesibhakabhaka noma umbala omnyama okwesibhakabhaka.

Phakathi kwezimpawu, kufanelekile ukugqamisa umbala ofanayo, usakaze phezu kwendawo yonke yokuguqula izithombe. Ngokuqondene nokucushwa kwendawo, kungase kuhluke ngokuphelele. I-nevus ingaba yindilinga noma i-oval. Kodwa-ke, ngokuvamile indawo yaseMongolia inesimo esingavamile. Ubukhulu bokushintshashintsha kwegazi buyahlukahluka. Kungaba yindawo eyodwa enkulu noma ezimbalwa ezincane.

Indawo yangakini ye-Mongolian Spot

Emntwini wengane yaseMongolia lapho izalwa ingahlala phansi kuphela ensimini ye-sacrum. Ngokuvamile, ukuguqulwa kwe-pigmentation kubonakala emhlane nasezintweni, kubamba izindawo ezinkulu kakhulu zesikhumba. Yiqiniso, izinsana eziningi zinezindawo eziluhlaza okwesibhakabhaka endaweni ye-coccyx futhi ephansi. Kodwa-ke, kunezimo lapho izindawo zemibala zikhonjiswe esikhumbeni se-forearm, emuva, izimpande nezinye izingxenye zomzimba.

Ezinye izingane zinezindawo zaseMongolia ezingashintsha indawo yazo. Ezimweni ezithile, ukuguqulwa kwesithombe kuguqulwa kuya emadodeni noma kusihlalweni.

Ingabe le ndawo iyanyamalala?

Ezinganeni ezisanda kuzalwa, indawo yaseMongolia inombala ogqamile. Kodwa-ke, emva kwesikhashana kuba mnyama futhi kancane kancane kudlulela. Ngesikhathi esifanayo, i-pigmentation iqala ukwehla ngesayizi. Kufanele kuqaphele ukuthi ezimweni eziningi indawo yaseMongolia iyanyamalala yedwa. Lokhu kwenzeka eminyakeni emihlanu emva kokuvela kwe-pigmentation esanda kuzalwa esikhumbeni.

Kwezinye izimo, indawo yaseMongolia ihlala futhi ayinyamalale kuze kube yilapho isencane. Kumele kuqashelwe ukuthi ezinganeni ezitholakala ngendawo yazo ezindaweni ezisezindaweni ezisemakhaya, isici singahlala isikhathi eside. Lokhu kusebenza futhi uma indawo yaseMongolia iqukethe ama-specks amaningi.

Izindlela zokuxilongwa

Uma kutholakala indawo enemibala esikhumbeni somntwana, okokuqala kudingeke ukuba ufune iseluleko esivela ku-dermatologist ekhethekile. Udokotela kufanele enze ukuxilongwa okungafani. Lokhu kuzokwenza ukuthi yini ukuchithwa kwe-pigmentation: indawo yaseMongolia noma ezinye izinhlobo ze-pigment nevi. Phela, amanye ama-neoplasms awafakiwe. Indawo yaseMongolia ingathathwa nge-nevus ye-nevus, i-veus eluhlaza okwesibhakabhaka, i-pigmentary pigmentary nevus njalonjalo. Zonke lezi zinhlayiya ziyi-melanoma enobungozi futhi zingabuyiselwa kabusha noma nini. Uma i-nevi enjalo ikhona esikhunjeni somntwana, kufanele ibhaliswe hhayi kuphela nge-dermatologist, kodwa futhi ne-oncologist.

Ukwenza ucwaningo olunembile, kwenziwa ucwaningo oluningana. Lolu hlu lubandakanya:

1. Dermatoscopy. Kulesi simo, i-neoplasm ihlolisiswa ngokucophelela ngaphansi kokwanda okuningi.
2. I-Siacopia. Lokhu kuthwetshwe kwe-spectrophotometric yendawo enemibala yesikhumba.
3. Ukuze uthole ukuxilongwa okunembile, i-biopsy yendawo ingenziwa. Le ndlela ivame ukusetshenziselwa ukubona izifo zendalo ehlukile, isibonelo, nge-warts, syringoma, nodal pruritis, njalonjalo.

Ukwelapha nokuvimbela

Emva kokuhlolwa okuphelele nokuxilongwa, i-dermatologist kufanele ibeke ukwelashwa okwanele. Uma ukuguqulwa esikhumbeni kuyindawo yaseMongolia, khona-ke ukwelashwa akukwenziwa. Ingane enezinguquko ezifanayo kufanele ibeke ku-akhawunti kuchwepheshe. Izingane ezinemibala yokugqoka kufanele zithole okungenani kanye ngonyaka ukuhlolwa okuhlukahlukene.

Kufanele kuqaphele ukuthi indawo yaseMongolia ayiyona isifo. Njengomthetho, i-pigmentation iyadlula yodwa futhi ingabangeli noma yikuphi ukungakhululeki. Ukuvimbela kulokhu akukwenziwa.

Isibikezelo

Uma indawo yaseMongolia ivela ku-coccyx noma emagodini ekubelethweni, khona-ke ingane ingabe ingesabi. Isibikezelo sinomusa ezimweni eziningi. Njengoba ucwaningo lubonisa, amacala okuguqulwa kwesibindi esinjalo nge-melanoma ayengakaqalwa. Ngesizathu esifanayo, indawo yaseMongolia ayidingi ukwelashwa. Ngemuva kweminyaka emihlanu ukubonakala kwe-pigmentation kungaqedwa. Kwamanye amacala kuphela okuqhubekayo ekukhuleni noma ehlala impilo. Indawo yaseMongolia ayibangeli noma ikuphi ukunganaki futhi ayikhathazi ingane.
