Melanocytic nevus - Nevus Melanocytichttps://en.wikipedia.org/wiki/Nevus
I- Nevus Melanocytic (Melanocytic nevus) luhlobo lwethumba lwe-melanocytic oluqulethe iiseli ze-nevus. Uninzi lwe-nevi lubonakala ngexesha leminyaka engamashumi amabini yokuqala yobomi bomntu. Ngokumalunga nomntwana omnye kwi-100 ngalinye elizalwa ne-nevi. I-nevi efunyenweyo luhlobo lwe-benign neoplasm, ngelixa i-congenital nevi ithathwa njenge-malformation encinci okanye i-hamartoma kwaye inokuba kumngcipheko ophezulu we-melanoma. I-Benign nevus ziyisetyhula okanye i-oval kwaye idla ngokuba yincinci (idla ngokuba phakathi kwe-1-3 mm), nangona ezinye zinokuba nkulu kunobukhulu be-eraser yepensile eqhelekileyo (5 mm). Ezinye iinevi zineenwele.

○ Unyango
Utyando lweLaser luqhele ukwenziwa ukususa i-nevi encinci ngokuthambisa. Ukuba ubungakanani bukhulu kune-4-5 mm, ukukhutshwa ngotyando kunokufuneka. Kubantwana abancinci, i-nevus enkulu kune-2 mm ngobukhulu ihlala kunzima ukuyisusa ngokupheleleyo ngaphandle kokulimala.

☆ Kwiziphumo zika-2022 ze-Stiftung Warentest ezivela eJamani, ukwaneliseka kwabathengi ngeModelDerm bekungaphantsi kancinci kunokubonisana nge-telemedicine ehlawulweyo.
  • Nevus eqhelekileyo
  • Becker nevus ― Igxalaba; ebonakala ngokukhula kweenwele kwi-nevus.
  • Nevus of Ota ― Ibonakala eluhlaza okwesibhakabhaka ngenxa yendawo enzulu yeeseli ze-nevus kumaleko wedermal. Kule meko yesigulane, i-nevus ifumaneka kwi-conjunctiva. Ota nevus inokususwa ngonyango lwelaser.
  • Compound nevus ― Impundu. Iimpawu zokuzalwa ezincinci zinokukhula zibe yi-nevi enkulu ngokukhula.
  • Intradermal nevus ― Ukumila kweqhuqhuva eliphumayo.
  • Nevus eqhelekileyo. Le mifanekiso mibini ingezantsi ithi intradermal nevus, kwaye le mifanekiso mithathu ingasentla ithi junctional nevus.
  • Blue nevus ― Ngenxa yendawo enzulu yeeseli ze-nevus, ibonakala ibhlowu.
  • Intradermal nevus ― Iqhele ukubonwa entloko.
  • Lo mfanekiso ubonisa isilonda se-nevus. Nangona kunjalo, ukuba isilonda esiphambili sincinci njengale, i-algorithm ayinakukwazi ukuqikelela ngokuchanekileyo imeko.

Congenital melanocytic nevus yi-melanocytic nevus ekhoyo ekuzalweni okanye evela kumanqanaba okugqibela obusana. I-Nevus sebaceous ichazwe njengendawo ehamarttomatous yeyunithi yepilosebaceous eneziphene. Apha, sichaza indlela esisebenzise ngayo ubuchule bombhobho nge Erbium:YAG laser ukunyanga izilonda ze-nevi kwizigulana ezahlukeneyo.
Congenital melanocytic nevus (CMN) is a melanocytic nevus that is either present at birth or appears during the latter stages of infancy. Nevus sebaceous has been described as the hamartomatous locus of an embryologically defective pilosebaceous unit. Here, we describe how we used the pinhole technique with an erbium-doped yttrium aluminium garnet (erbium : YAG) laser to treat nevi lesions in different patients.

I-melanoma luhlobo lwethumba elenza xa i-melanocytes, iiseli ezinoxanduva lombala wolusu, ziba nomhlaza. I-Melanocytes ivela kwi-neural crest. Oku kuthetha ukuba i-melanomas ayinakukhula kuphela eluswini kodwa nakwezinye iindawo apho iiseli ze-neural crest zifuduka, njengephecana lesisu kunye nengqondo. Izinga lokusinda kwizigulane ezine-melanoma yesigaba sokuqala (inqanaba le-0) liphezulu kuma-97%, ngelixa lehla kakhulu malunga ne-10% kwabo bafunyaniswa ukuba banesifo senqanaba eliphezulu (inqanaba IV) .
A melanoma is a tumor produced by the malignant transformation of melanocytes. Melanocytes are derived from the neural crest; consequently, melanomas, although they usually occur on the skin, can arise in other locations where neural crest cells migrate, such as the gastrointestinal tract and brain. The five-year relative survival rate for patients with stage 0 melanoma is 97%, compared with about 10% for those with stage IV disease.
