“…Clinically, it appears as a yellowish verrucous plaque usually on the scalp or forehead. It may appear at birth or develop during childhood as smooth, yellowish, hairless patches, and change into elevated verrucous plaque during puberty 10 11 . On histopathology, the epidermis shows acanthosis and papillomatosis, and sebaceous gland hyperplasia; immature hair follicles are observed in the dermis 12 .…”

Folliculocystic and collagen hamartoma is a newly described complex hamartoma characterized by abundant collagen deposition, concentric perifollicular fibrosis, and keratin- filled infundibular cysts that are visible on histopathological examination. Here, we report the case of a 19-year-old Korean man who had large brownish infiltrated plaques with numerous follicular comedo-like openings and subcutaneous cystic masses on his right temporal scalp and ear since birth. Histopathological examination showed abundant collagen deposition in the dermis that extended up to the subcutaneous fat layer, multifocal infundibular cysts packed with keratin, and perifollicular inflammation and fibrosis. Hence, we describe a new type of hamartoma with folliculocystic and collagen components but without tuberous sclerosis.

“… 4 This condition is most commonly found on the hairy scalp, face, and neck, but rarely presents on the chest and oral mucosa. 5 , 6 The typical clinical manifestation of NS consists of three stages. 7 At initial stage, the lesion is round, oval, or linear, flat, slightly yellowish, and hairless.…”

Nevus sebaceus (NS) or organoid nevus is an epidermal nevus comprising predominantly sebaceous glands with a prevalence of approximately 0.3% of the newborns. The initial clinical manifestations of NS are single or less commonly multiple yellowish patches with overlying alopecia, usually confined to the scalp. However, it can also appear on the face, preauricular area, and the neck. During puberty, skin lesions will turn into round or linear verrucous plaques accompanied with an increase in number due to the influence of androgens. As they progress, about 20% of the NS cases might turn into secondary tumors which can be benign or malignant (in 2.5% cases). NS can manifest as atypical lesions and may also arise on areas other than its predilection sites. A case of a lesion presented on an atypical location of an 18-year-old male patient treated with carbon dioxide (CO 2 ) laser was reported. Physical examination revealed skin-colored and blackish-brown papules arranged in groups on the left side of the patient’s chest. Histopathological examination on a sample taken from one of the skin lesions on the chest showed hyperkeratosis, acanthosis, papillomatosis, and sebaceous hyperplasia, confirming the diagnosis of NS. The patient was treated with CO 2 laser, and clinical improvements were observed. Histopathological examination of NS is not routinely performed; however, it should be carried out when the lesion is atypical and presented at an unusual location, or there is a suspicion of malignancy.

“…[ 5 ] Further, there are a few case reports of NSJ on face and usually are associated with scalp involvement. [ 6 7 ] In this case, we report dermoscopic features of an isolated lesion of nevus sebaceous on face without involvement of scalp, which is quite rare. Furthermore, in our case we also found perifollicular yellowish-brown globules, which may be secondary to follicular plugging.…”
