Urticaria pigmentosa ke lefu la letlalo le hlahisang matheba a letlalo le letšo le ho hlohlona ho hobe haholo. Hives e ka hlaha ha libaka tsena tsa letlalo li tšeloa.

Urticaria pigmentosa e etsahala ha ho na le lisele tse ngata haholo tsa ho ruruha letlalong. Lisele tse nyenyane ke lisele tsa sesole sa 'mele tse thusang' mele ho loants'a mafu. Lisele tsa 'mele li etsa le ho ntša histamine, e bakang lisele tse haufi ho ruruha le ho ruruha.

Lintho tse ka hlahisang phallo ea histamine le matšoao a letlalo li kenyelletsa:

  • Ho hohla letlalo
  • Tšoaetso
  • Ho ikoetlisa
  • Ho noa maro a chesang, ho ja lijo tse nokiloeng ka linoko tse ngata
  • Khanya ea letsatsi, ho pepesehela serame
  • Meriana, e kang aspirin kapa li-NSAID tse ling, codeine, morphine, dae ea x-ray, meriana e meng ea anesthesia, joala

Urticaria pigmentosa e atile haholo ho bana. E ka boela ea etsahala ho batho ba baholo.

Letšoao le ka sehloohong ke mabala a sootho letlalong. Li-patches tsena li na le lisele tse bitsoang mastocyte. Ha li-mastocyte li ntša k'hemik'hale ea histamine, li-patches li fetoha makukuno a tšoanang le a hive. Bana ba banyenyane ba ka ba le blister e tlatsitsoeng ke mokelikeli haeba bump e hohliloe.


Sefahleho le sona se ka ba khubelu kapele.

Maemong a boima, matšoao ana a ka hlaha:

  • Letšollo
  • Ho tepella (ho sa tloaelehang)
  • Ho opeloa ke hlooho
  • Wheeze
  • Ho otla ha pelo kapele

Mofani oa tlhokomelo ea bophelo o tla hlahloba letlalo. Mofani oa thepa a ka belaella urticarial pigmentosa ha matlalo a letlalo a hohla le ho phahamisa makhopho. Sena se bitsoa lets'oao la Darier.

Liteko tsa ho lekola boemo bona ke:

  • Letlalo biopsy ho batla palo e phahameng ea lisele tsa mast
  • Histamine ea moroto
  • Liteko tsa mali bakeng sa palo ea lisele tsa mali le maemo a tryptase ea mali (tryptase ke enzyme e fumanoang liseleng tsa mast)

Meriana ea antihistamine e ka thusa ho imolla matšoao a kang ho hlohlona le ho hohola. Bua le mofani oa hau mabapi le mofuta oa antihistamine eo u ka e sebelisang. Corticosteroids e sebelisitsoeng letlalong le kalafo e bobebe e ka sebelisoa maemong a mang.

Mofani oa hau a ka fana ka mefuta e meng ea meriana ho phekola matšoao a mefuta e matla le e sa tloaelehang ea urticaria pigmentosa.


Urticaria pigmentosa e fela ka ho kena bohlankaneng kapa boroetsaneng hoo e ka bang halofo ea bana ba amehileng. Matšoao a lula a ntlafala ho ba bang ha ba ntse ba hola ho ba batho ba baholo.

Ho batho ba baholo, urticaria pigmentosa e ka lebisa ho systemic mastocytosis. Boemo bona ke bo tebileng bo ka amang masapo, boko, methapo le tsamaiso ea tšilo ea lijo.

Mathata a mantlha ha a phutholohe ke ho hlohlona le ho ameha ka ponahalo ea matheba. Mathata a mang a kang letšollo le ho akheha ha a fumanehe hangata.

Likokoana-hloko li ka boela tsa baka tšoaetso e mpe ho batho ba nang le urticaria pigmentosa. Botsa mofani oa hau hore na u ka nka epinephrine kit eo u ka e sebelisang ha u e-na le notši.

Bitsa mofani oa hau haeba u bona matšoao a urticaria pigmentosa.
