Nevus Sebaceous at an Unusual Location： A Rare Presentation

To the Editor： Nevus sebaceous （NS） is an epidermal nevus that is comprised predominantly of sebaceous glands in approximately 0.3% of newborns.[1] Clinically, it presents as a single or, less commonly, multiple yellowish-colored plaques with overlying alopecia, usually confined on the scalp; however, it can also appear on the face, preauricular area, and neck region.[2,3] Here, we reported a case of NS in a discrete linear pattern located on the left chest region, in contrast with typical cases, to assist physicians in the early diagnosis of this condition and to prevent unnecessary examinations and inadequate therapeutic interventions.
