Sebaceous Neoplasms – Nevus Sebaceous

February 12th, 2011

Neuvs Sebaceous is a type of “birthmark” that occurs in .3% of all newborns and I occasionally encounter this lesion in my The Woodlands dermatology and Conroe dermatology offices.  Nevus Sebaceous are most commonly found on the scalp but can be found on the face and neck and very rarely on the trunk.  Nevus Sebaceous appears as a yellow/orange raised smooth or verrucous plaque that causes alopecia if it is on a hair bearing area.  Other tumors can arise in a Nevus Sebaceous with trichoblastomas and syringocystadenoma papilliferum being the most common.  In 1% of all Nevus Sebaceous, a Basal Cell Cancer may arise and the risk of tumor development increases with age.  In some patients, a Nevus Sebaceous may be associated with internal abnormalities.  Treatment of Nevus Sebaceous is patient dependent and involves surgical excision if the patient desires removal.  This decision can be delayed until adulthood as malignancies usually do not occur in these lesions during childhood.Neuvs Sebaceous is a type of “birthmark” that occurs in .3% of all newborns and I occasionally encounter this lesion in my The Woodlands dermatology and Conroe dermatology offices.  Nevus Sebaceous are most commonly found on the scalp but can be found on the face and neck and very rarely on the trunk.  Nevus Sebaceous appears as a yellow/orange raised smooth or verrucous plaque that causes alopecia if it is on a hair bearing area.  Other tumors can arise in a Nevus Sebaceous with trichoblastomas and syringocystadenoma papilliferum being the most common.  In 1% of all Nevus Sebaceous, a Basal Cell Cancer may arise and the risk of tumor development increases with age.  In some patients, a Nevus Sebaceous may be associated with internal abnormalities.  Treatment of Nevus Sebaceous is patient dependent and involves surgical excision if the patient desires removal.  This decision can be delayed until adulthood as malignancies usually do not occur in these lesions during childhood.Nevus Sebaceous
