Naevus comednicus is a rare form of epidermal naevus commonly seen on face and neck. Much rare is the occurrence of lesions over the glans. Reported cases of this developmental abnormality of pilosebaceous apparatus are few. Here we report a case with lesions over cheek and glans penis.

  Introduction Top

Naevus comedonicus is an uncommon form of epidermal naevus characterized by closely set, slightly elevated papules that have in their centre a dark, firm, hyperkeratotic plug resembling a comedone. It is thought to be a developmental abnormality of the pilosebaceous apparatus. [1] This rare condition occurs mostly on the face, trunk or neck in a unilateral, linear pattern. [2] Lesions rarely occur on the palms, soles and glans penis. [3] Their occurrence in these areas argues against their pilosebaceous origin. [4]

subIn half the cases the naevus is present at birth. There is no racial or sexual predisposition. It tends to grow as the child matures and a expanding lesion gives a nutmeg grater-like feeling to the skin. [5]

The naevus is usually asymptomatic. Rarely, inflammatory changes may occur when it is called naevus acneiformis [4] Associated abnormalities_ of bone, central nervous system and eyes are infrequent. [1] It has been reported to occur as a sequel of lichen planus, herpes zoster and vaccination. [4]

Histopathologically each comedone is represented by a wide, deep Invagination resembling dilated, rudimentary hair follicles. [6]

Here a case with lesions over cheek and glans penis is being reported.

  Case Report Top

A 10-year-old boy, born to nonconsanguineous parents had a gradually increasing pitted lesion on the right cheek since birth. There was no preceding or associated dermatoses or systemic features. [Figure - 1].

There was a single, well defined lesion of 7x4 cms size on the right cheek extending above the ear lobe. Its irregular surface showed multiple pits and keratotic plugs. The plugs were easily removable without any consequence. The lesion was confined to the skin and was asymptomatic. The glans penis had 3 keratotic patches without pits. [Figure - 2] Skin on other parts of the body was normal. There were no associated constitutional features.

Biopsy from the lesion revealed a deep cystic invagination of the epidermis, filled with keratin and hair shafts. Surrounding dermal tissue showed pigmented epithelial buds, sebaceous glands, normal eccrine glands and a sparse inflammatory infiltrate. [Figure - 3].

Dermabrasion was performed. A month later the site showed multiple milia and keloid formation. [Figure - 4].

  Discussion Top

Very rare is the occurrence of Naevus comedonicus on the glans penis. Our case had lesions over the glans penis.
