Scabies is highly contagious and is usually transmitted by direct personal contact. It typically presents as an intensely pruritic eruption. Atypical presentations are common in Norwegian scabies and in childhood scabies. Infestation is documented by visualizing the mite, its eggs or scybala on low-power microscopy. The treatment of choice is 5 percent permethrin cream, used in a single application at bedtime and removed the next morning.
The need for daily sunscreen use has become increasingly evident over the last several decades. In a population that spends more recreational time in the sun than ever before, there is a growing awareness of the harmful effects of sunlight exposure. Patients who have a photosensitivity disorder or who are taking photosensitizing medications may also benefit from the use of new broad-spectrum superpotent sunscreens.

A case of scabies infestation in a ten-week-old infant is described. Infestation in a neonate presents a clinical picture quite different from that found in older children and adults. Therapeutic options can be limited in infants. Current concepts and treatment modalities are discussed.
Laugier-Hunziker syndrome is a rare, benign pigmentation disorder previously described only once in the United States. The syndrome is acquired in early or mid-adult life and is characterized by multiple longitudinal hyperpigmented bands on the nails and pigmented macules of the lips and buccal mucosa. Peutz-Jeghers syndrome and Addison's disease can present with pigment abnormalities similar to those characteristic of Laugier-Hunziker syndrome.
