Evaluation and management of an unusual congenital nevus.

Abnormal findings on routine skin exams are common and can be a source of unnecessary medical workup if a clinician is unfamiliar with the finding. Sebaceous nevi are rare skin lesions that are most often benign but may be associated with a multiorgan syndrome or local skin cancer. Dermatologists and primary care physicians may encounter these on routine exams and thus must be comfortable with diagnosis and management. We present the clinical characteristics of a benign sebaceous nevus to help aid in diagnosis of these lesions and outline suggestions for appropriate management options.
