Linear and whorled nevoid hypermelanosis

Linear and whorled nevoid hypermelanosis (LWNHM) is a reticulate pigmentary disorder with a sporadic occurrence, representing genetic mosaicism. It is characterised by hyperpigmented macules in a reticulate pattern along Blaschko's lines, sparing the mucous membranes and stabilising after one to two years. It may be associated with various neurological abnormalities. The disorder may resemble incontinentia pigmenti, epidermal nevus, or zebra-like hyperpigmentation clinically. We report LWMNHM in a 15-year-old girl with progressively increasing streaks of reticulate hyperpigmented macules arranged in a whorled pattern over the trunk and extremities, which appeared soon after birth. There was no history of any preceding eruption or any associated systemic abnormality. Histopathological examination revealed basal cell hyperpigmentation without any pigmentary incontinence. CT scan of the brain was normal.     

Linear and whorled nevoid hypermelanosis complicated with inflammatory linear verrucous epidermal nevus and ichthyosis vulgaris

We report a 17-year-old girl who presented with linear and whorled melanosis following Blaschko lines mainly on her trunk. Ichthyosiform lesions and linear scaling erythemas were observed respectively on her lower limbs and the dorsa of her hands, left knee, ankle and foot. No abnormality was found in systemic examination and blood tests. A biopsy specimen of pigmentation of her back showed there was increased pigmentation within the basal keratinocytes, with focal incontinentia pigmenti. Notable lymphangiectasis could also be seen in the mid part of dermis, which had never previously been described. The biopsy of scaling erythemas of her hand showed dominant hyperkeratosis with focal parakeratosis, acanthosis and papillomatous hyperplasia in the epidermis. The diagnosis of linear and whorled nevoid hypermelanosis (LWNH) complicated with inflammatory linear verrucous epidermal nevus and ichthyosis vulgaris was made in accordance with clinical and pathological manifestations. LWNH ought to be differentiated from incontinentia pigmenti and hypomelanosis of Ito.

Linear and whorled nevoid hypermelanosis

Linear and whorled nevoid hypermelanosis (LWNH) is a rare skin condition characterized by swirls and whorls of hyperpigmented macules in a reticulate pattern along Blaschko's lines; approximately 40 cases have been reported in the English language literature. We report a case of LWNH occurring in a 20-year-old man with widespread involvement over the trunk, face, upper limbs, and genitalia in association with scoliosis. A small hyperpigmented area on the abdomen was treated with a medium-depth chemical peel regimen using 70 percent glycolic acid and 35 percent trichloroacetic acid with no benefit. This is the first report of LWNH treated with medium-depth chemical peel.     

Linear and whorled nevoid hypermelanosis

Two cases are presented of congenital linear and whorled hypermelanosis. Hyperpigmented macules in streaky configurations along Blaschko's lines appeared gradually after birth. Histologic examination revealed prominent epidermal melanocytes and irregular basal layer hyperpigmentation with normal melanosomes. This condition must be differentiated from incontinentia pigmenti, early systematized epidermal nevus, extensive hypomelanosis of Ito, and chimerism. Other similar case reports from the literature suggest that incidence is sporadic and may be associated with more serious congenital anomalies. The patterning is the inverse to that found in hypomelanosis of Ito. Developmental somatic mosaicism may be responsible for this patterned hypermelanosis.     

Linear and whorled naevoid hypermelanosis: a case with systemic involvement and trisomy 18 mosaicism
