Congenital nevus - Congenita Nevushttps://en.wikipedia.org/wiki/Congenital_melanocytic_nevus
Congenita Nevus (Congenital nevus) est species nevus melanocytici, quae in infantibus nascentibus invenitur. Haec forma notae in 1 % infantium occurrit.

Comparata cum nevo melanocytico, nevi melanocytici congeniti plerumque maiores sunt in diametro et capillos superfluos habere possunt. Si diametrus superat 40 cm cum hypertrichosis, interdum nevus pilosus gigas appellatur.

Nevi melanocytici saepe proportionaliter crescunt cum magnitudine corporis, sicut puer maturescit. Pilus prominens saepe formatur, praesertim post pubertatem.

Excisio chirurgica est curatio primaria. Multae nevi aestheticæ chirurgice removentur. Tamen maiores nevi maior periculum cancri habent. Nevi congenitae gigantes in periculo maiori sunt propter transformationem in melanoma. Incidence transformationis in melanoma variat inter 2‑42 % in studiis.

Ubi nevi parvi sunt, facile chirurgice removeri possunt. Remotio difficillima est sine cicatrice, praesertim cum nevi antiquus est.

  • Difficile est magnum nevi nasi omnino removere, si in neonatali aetate non removeretur.
  • Congenita Nevus (Congenital nevus) (casus typicus) — In neonatali aetate puncta parva incipiunt, sed in aetate maiori crescunt. Ex parte medica, melius est, cum est parvum, tollere.
  • In causis magnae implicationis, alta est probabilitas cancer cutis in futurum evolvi.
  • Si figuram irregularem habet, biopsy necessaria est.

Congenital melanocytic nevus est genus naevi quod vel in nativitate vel in infantia progreditur. Nevus sebaceous est defectus pellis cum folliculis pilorum deficientibus. In hoc studio, technica laser artis adhibita est, quam modum pinholae nominavi, cum laser Erbium:YAG, ut vitia nevus in variis patientibus tractaretur.
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.

Giant congenital melanocytic nevus — macula pelliculae obscurae genus est, quod a nativitate crescit et, cum homo adultus est, plus quam 20 cm latum est. Vere rara est: minus quam 1 in viginti milibus natorum evenit. Quamvis rara, est tamen gravis, quia potest ducere ad problemata gravia, sicut cancer cutis, aut afficere cerebrum et nervos (melanosis neurocutaneos). Probabilitas canceris cutis ex eo aliquando in vita tua est inter 5 et 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%.
