A 7-year-old boy was brought for evaluation of a rash on the chin that had appeared 2 weeks earlier. It was slightly itchy. The mother had applied a topical corticosteroid for a few days but then stopped because of worsening of the lesion.

The parents of this 5-month-old boy were concerned that his eyes were turned in toward the nose. The infant was otherwise healthy. Physical examination findings were normal. In particular, when a light source was projected onto the eyes, the light reflex was centered in both eyes.

Ten-year-old girl assessed because of limitation of neck motion. Born at term to non-consanguineous parents. No history of necktrauma. Family history andpast health unremarkable.

A 7-year-old boy presented with an asymptomatic cystic lesion on the lateral aspect of the left ankle of 4 months' duration. There was no history of trauma. The mass fluctuated in size: it was smaller when the child was recumbent and larger when the child was upright.

This black lesion had been present on the upper back of a 5-year-old girl since her birth. The lesion had gradually enlarged to its current size of 1.5 cm. In the past year, 3 satellite black macules had developed in the surrounding area.

This 14-year-old girl had first noticed the well-circumscribed, roughened, irregular growth on her right middle finger 6 months earlier. The lesion had progressively enlarged. The girl's mother had a similar, but smaller, lesion on the left elbow. Alexander K. C. Leung, MD, and Justine H. S. Fong, MD, of Calgary, Alberta, diagnosed verruca vulgaris. This proliferative, hyperkeratotic, exophytic lesion is most commonly caused by human papillomavirus types 2 and 4.

For the past 10 days, a 3-week-old infant had a rash on the face. He was born at term to a healthy, 22-year-old primigravida, following an uncomplicated pregnancy and normal spontaneous vaginal delivery (birth weight, 3.1 kg; length, 49.5 cm). Numerous comedones and papules were noted on the infant's cheeks.
