Pityriasis alba

I-Pityriasis alba yisifo esijwayelekile sesikhumba semigqa yezindawo ezinemibala ekhanyayo (ene-hypopigmented).

Imbangela ayaziwa kepha ingaxhunyaniswa ne-atopic dermatitis (eczema). Lesi sifo sivame kakhulu ezinganeni nasebusheni. Kubonakala kakhulu ezinganeni ezinesikhumba esimnyama.

Izindawo ezinenkinga esikhunjeni (izilonda) zivame ukuqala njengamachashazi abomvu kancanyana nalawo anezikwele ayindilinga noma amise okweqanda. Imvamisa zivela ebusweni, ezingalweni ezingaphezulu, entanyeni, naphakathi nendawo emzimbeni. Ngemuva kokuthi lezi zilonda zihambe, amachashazi aphenduka abe nombala okhanyayo (hypopigmented).

Amabala awashisi kalula. Ngenxa yalokhu, zingaba bomvu ngokushesha elangeni. Njengoba isikhumba esizungeze ama-patches simnyama ngokujwayelekile, amabala angahle abonakale kakhulu.

Umhlinzeki wezokunakekelwa kwempilo uvamise ukuxilonga lesi simo ngokubheka isikhumba. Ukuhlolwa, okufana ne-potassium hydroxide (KOH), kungenziwa ukukhipha ezinye izinkinga zesikhumba. Ezimweni ezingavamile kakhulu, kwenziwa i-biopsy yesikhumba.

Umhlinzeki angancoma ukwelashwa okulandelayo:

• Amafutha
• Okhilimu abancane be-steroid
• Imithi, ebizwa ngama-immunomodulators, isetshenziswe esikhumbeni ukunciphisa ukuvuvukala
• Ukwelashwa ngokukhanya kwe-ultraviolet ukulawula ukuvuvukala
• Imithi ngomlomo noma ngesibhamu ukulawula i-dermatitis, uma inzima kakhulu
• Ukwelashwa nge-Laser

IPityriasis alba ivamise ukuzihambela yodwa ngamachashazi abuyela kumbala ojwayelekile ezinyangeni eziningi.

Amachashazi angashiswa yilanga lapho evezwa yilanga. Ukufaka i-sunscreen nokusebenzisa okunye ukuvikela ilanga kungasiza ekuvimbeleni ukushiswa yilanga.

Shayela umhlinzeki wakho uma ingane yakho ineziqeshana zesikhumba se-hypopigmented.
