Puloteni wotchedwa melanonychia ndi kukhalapo kwa mgulu wofiira, kawirikawiri bulauni kapena wakuda, komanso kutalika kwa bedi. Amakonda anthu omwe ali ndi khungu. Malonda a khungu la melanonychia amachokera ku dothi la msomali kuchokera ku zifukwa zosiyanasiyana. Chiwerengero cha anthu omwe ali ndi longitudinal melanonychia ali ndi subungual melanoma .
Zimayambitsa
Nkhumba mu misomali yanu imapangidwa ndi maselo otchedwa melanocytes mu bedi la msomali. Zimapanga melanin, mtundu umene umapatsa tsitsi komanso umatulutsa khungu la khungu lanu. Pa bedi la msomali, amasuntha melanin ku maselo omwe akupanga msomali. Mukawona mzere wandiweyani pamsomali wanu, ndipamene iwo akupanga melanin kwambiri m'munsi ndipo amapanga mzere pamene msomali ukukula panja.
Zomwe zimayambitsa melanonychia zimagawidwa m'magulu a melanocytic activation, pamene maselo omwe alipo kale amayamba kutulutsa melanin, ndi melanocytic hyperplasia kumene maselo ambiri opanga pigiti amachuluka.
Zotsatira za Benign
Kawirikawiri mudzawona mdima wamdima mumsomodzi umodzi. Pa 73% mwa akuluakulu akuluakulu, izi zimachokera ku maselo omwe alipo kale omwe amapanga pigment zambiri. Mtundu wa khungu lanu ndilo chifukwa cha izi, popeza anthu omwe ali ndi khungu lakuda minofu amakhala ndi misomali yambiri yamtundu wautali m'misomali yawo.
Iwe umapeza zambiri pamene iwe uli usinkhu, ndipo iwo amachulukira. Zimapezeka nthawi zambiri pa zala zomwe mumagwiritsa ntchito kuti mugwire zinthu-thupi lanu, ndondomeko, ndi chala chapakati.
Mimba ndi nthawi ina pamene mumakhala ndi nthawi yaitali kuti muwonetse kutalika kotentha kwa melanonychia. Kukhumudwitsidwa kwa mbale ya msomali kungayambitsenso. Ngati muwona mikwingwirima pa chala chaching'ono kapena chala chala chachikulu, chikhoza kukhala chifukwa cha zala zanu zakumanga nsapato zanu ngati sizikugwirizana.
Matenda a fungal a msomali amatha kuyambitsa mdima, monga psoriasis, matenda a khungu kuzungulira msomali, amyloidosis, ndi lichen planus.Zikhozanso kuwonekera, nthawi zambiri ndi magulu angapo, mu Addison's and AIDS.
Chemotherapy, X-rays ndi mankhwala a electron piritsi angayambitse mankhwalawa, kuphatikizapo misomali yambiri. Zitha kuoneka mu matenda a Laugier-Hunziker, Peutz-Jeghers matenda, ndi matenda a Touraine.
Melanocytic Hyperplasia-Benign ndi Malignant Melanoma
Ma Melanocyte amatha kuchulukitsa ndi kutulutsa melanonychia muzoopsa kapena zovuta. Benign hyperplasia ikhoza kukhala m'majekiti (mawanga) kapena nevi (zisa). Kwa ana, 77.5% mwa matenda a melanonychia amayamba chifukwa cha matenda a melanocytic hyperplasia.
Malignant melanocytic hyperplasia ikhoza kukhala chifukwa cha melanoma yoopsa kapena in situ. Kawirikawiri amawoneka pa thupi, chachikulu chala chala kapena kulongosola chala. Zimapezeka kawirikawiri m'mitundu yonse, pamene khansa ya khansa ya m'magawo ena imakhala yosiyana kwambiri ndi mafuko a mdima.
Mayesero Opatsirana
Kuti athetse khansa yotchedwa melanoma, chidziwitso chimachitika nthawi zambiri. Chidutswachi chimatenga minofu ku msomali wa msomali, womwe ukhoza kuwonetsa. Izi sizingakhale zomwe mukufuna, koma khansa ya khansa imakhala matenda aakulu omwe amafunikira chithandizo.
