Congenital nevus - Nevus Congenitalhttps://en.wikipedia.org/wiki/Congenital_melanocytic_nevus
Tha Nevus Congenital (Congenital nevus) na sheòrsa de melanocytic nevus a lorgar ann am pàisdean aig àm breith. Tha an seòrsa comharra-breith seo a’ nochdadh ann an timcheall air 1% de leanabain air feadh an t-saoghail.

An coimeas ri melanocytic nevus, mar as trice bidh congenital melanocytic nevi nas motha ann an trast‑tomhas agus faodaidh gum bi cus falt orra. Ma tha còrr air 40 cm (16 a-steach) le hypertrichosis, uaireannan canar giant hairy nevus ris.

Bidh congenital melanocytic nevi gu tric a’ fàs ann an co‑rèir ri meud a’ chuirp mar a bhios an leanabh a’ tighinn gu ìre. Bidh falt follaiseach gu tric a’ cruthachadh, gu h-àraidh às deidh breith‑bhìde.

Is e gearradh lannsa an ìre cùraim. Tha mòran air an toirt air falbh le lannsaireachd airson bòidhchead. Ach, tha feadhainn nas motha air an gearradh airson casg malignant transformation gu melanoma. Tha giant congenital nevus ann an cunnart nas àirde airson malignant transformation gu melanoma. Tha tuairmsean de chruth‑atharrachadh gu melanoma eadar‑dhealaichte bho 2‑42 % anns an litreachas.

Nuair a tha an lesion beag, faodar a thoirt air falbh le lannsaireachd. Ach, tha e gu math duilich a thoirt air falbh gu tur gun scar nuair a dh’fhàsas e mòr le aois.

  • Tha e duilich nevi mòr a thoirt air falbh air an t-sròin mura tèid an toirt air falbh anns an ùine ùr-bhreith.
  • Congenital nevus - Bidh e a’ tòiseachadh le dotagan beaga anns an ùine ùr-bhreith, ach bidh e a’ fàs nas motha thar ùine. Bho shealladh cosmaigeach, tha e nas fheàrr a thoirt air falbh nuair a tha e beag.
  • Ann an cùisean far a bheil com-pàirt farsaing ann, tha coltas ann gun tèid aillse craiceann a leasachadh san àm ri teachd.
  • Leis gu bheil cumadh neo-riaghailteach air, tha feum air biopsy.

Is e seòrsa de chomharra breith a th’ ann an Congenital melanocytic nevus a leasaicheas an dàrna cuid aig àm breith no aig àm leanabachd. Tha Nevus sebaceous na ana-cainnt craiceann anns a bheil follicles fuilt easbhaidheach. Anns an sgrùdadh seo, chleachd sinn innleachd laser ris an canar an dòigh pinhole le Erbium‑doped YAG laser gus nevus lesions a làimhseachadh ann an grunn euslaintich.
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.

Is e seòrsa de nevus a th’ ann an Giant congenital melanocytic nevus a tha ann bho bhreith agus a dh’ fhàsas gu bhith còrr air 20 cm a leud nuair a tha duine làn fhàs. Tha e gu math tearc, a’ tachairt ann an nas lugha na 1 às gach 20,000 ùr‑breith. Eadhon ged a tha e tearc, tha e gu math mòr oir faodaidh e leantainn gu fìor dhuilgheadasan leithid skin cancer no buaidh a thoirt air an eanchainn agus nerves (neurocutaneous melanosis). Tha an cothrom air skin cancer fhaighinn bhuaithe uaireigin nad bheatha eadar 5 is 10%.
Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated in <1:20,000 newborns. Despite its rarity, this lesion is important because it may associate with severe complications such as malignant melanoma, affect the central nervous system (neurocutaneous melanosis). The estimated lifetime risk of developing melanoma varies from 5 to 10%.
