Orgarnoid nevus https://en.wikipedia.org/wiki/Nevus_sebaceous
Orgarnoid nevus is in oanberne, hierleaze dikke lesion dy't typysk op it gesicht of de skalp foarkomt. Sokke nevi wurden klassifisearre as epidermal nevi en kinne oanwêzich wêze by berte, of iere bernetiid.

Basal cell carcinoma kin ûntstean yn sebaceous nevi, meastal yn folwoeksenen. It is lykwols no bekend dat it taryf fan sokke maligniteiten minder is dan rûsd. Om dizze reden wurdt profylaktyske excision net mear oanrikkemandearre.

Nevus sebaceus is in bertedefekt wêrby't in abnormale groei fan hierfollikels en oaljeklieren is. Dizze groeien komme faak foar op 'e hoofdhuid, mar kinne ek ferskine op' e foarholle, gesicht of hals. Se tendere mear te groeien yn 'e puberteit fanwege hormonale feroaringen. As folwoeksenen kinne dizze groeien ekstra tumors ûntwikkelje (trichoblastoma). Hoe dizze groei behannele wurdt, is noch omsteld, mei opsjes fan observaasje (observation) oant betiid eksisie (excision) yn bernetiid.
Nevus sebaceus of Jadassohn also referred to as organoid nevus, is a congenital malformation involving hamartomas of the pilosebaceous follicular unit. These growths most commonly form on the scalp, but may also appear on the forehead, face, or neck. They undergo a growth phase during puberty due to hormonal changes. In adulthood, the growths may develop secondary neoplasms within them, most commonly trichoblastoma. The treatment of these lesions is controversial, with options ranging from observation to early excision in childhood.
 Effective Treatment of Congenital Melanocytic Nevus and Nevus Sebaceous Using the Pinhole Method with the Erbium-Doped Yttrium Aluminium Garnet Laser 25324667

Congenital melanocytic nevus is in soarte bertemerk dat ûntwikkelt by berte of yn 'e bernetiid. Nevus sebaceous is in hûdabnormaliteit mei defekte hierfollikels. Yn dizze stúdzje brûkten wy in lasertechnyk neamd de pinhole-metoade mei in Erbium: YAG laser om nevus-lêsjes te behanneljen yn ferskate pasjinten.
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.
