To the Editor: Nevus sebaceous (NS) is an epidermal nevus
that is comprised predominantly of sebaceous glands in approximately 0.
Other dermatoses observed in this study were Lichen striatus, Linear Lichen planus, inflammatory Linear verrucous epidermal nevus
, Lichen nitidus, Paederus dermatitis, Hypomelanosis of Ito, Linear and Whorled nevoid hypermelanosis.
Syndromic hemimegalencephaly (for example, epidermal nevus
syndrome and Proteus Syndrome) is associated with other features which include hemicorporal hypertrophy of the ipsilateral part of the body.
The clinical differential diagnosis for NS includes seborrheic keratosis, congenital nevus, and epidermal nevus
Nevus sebaceous (NS) is considered a subtype of an epidermal nevus
, a benign hamartoma that includes an excess or deficiency of structural elements of the skin, such as epidermis, sebaceous, and apocrine glands.
Some consider linear psoriasis to be either synonymous with inflammatory linear verrucous epidermal nevus
(ILVEN) or an invasion of pre-existing epidermal nevus
by psoriasis due to koebnerisation.
Nevus comedonicus, also known as comedo nevus or follicular nevus, is a rare subtype of epidermal nevus
, first described in 1895 by Kofmann .
Here, we present a child with terra firma-forme dermatosis who has been previously diagnosed with epidermal nevus
Other cutaneous lesions also related to amyloid deposits are linear verrucous epidermal nevus
(23), melanocytic nevus (23, 24), seborrheic kerato-sis (5), actinic keratosis (6), or Bowen's disease (25).
Basaloid follicular hamartoma in a linear distribution may mimic linear epidermal nevus
, lichen striatus, linear morphea, and basal cell nevus.
He had been seen by other dermatologists and previous diagnoses included epidermal nevus
and linear psoriasis.
