A 13-year-old girl noticed that the skin around a "mole" on her abdomen had gradually changed color. This patient was told that she had a halo nevus--a pigmented (nevocellular) nevus surrounded by a tight ring of depigmentation--which is benign and usually regresses spontaneously over time. This relatively common lesion is believed to affect males and females equally. The development of the halo may coincide with puberty or pregnancy. Often, several pigmented nevi develop a halo simultaneously.

A 4-year-old girl was brought to a local emergency department (ED) after an episode of dizziness, vomiting, and horizontal nystagmus.

Two examples of polydactyly are shown. Photos A and B show a female newborn's right hand with an almost fully developed extra thumb; the radiograph shows what appears to be the distal phalanx bone of the extra digit.

A thriving boy was brought to the office 3 weeks after his first birthday. His mother reported that there was "something wrong with his knee." On visual examination, the knee appeared perfectly normal. On palpation, however, a 4-cm linear induration was evident over the knee fat pad, just medial and distal to the patella. It appeared soft, crepitant, and associated with the skin. No tenderness was noted on palpation; the infant did not object to palpation of this density any more than to auscultation, otoscopy, or anthropometric measurements. No erythema, ecchymosis, or signs of trauma were evident near the lesion. The only possibly relevant history was that the child had spent his birthday at his grandmother's home in the Ukraine a month earlier. He was constantly with his mother during that time, and no trauma was ever reported.

Foreign-body aspiration is a relatively common occurrence in children. It may present as a life-threatening event that necessitates prompt removal of the aspirated material. However, the diagnosis may be delayed when the history is atypical, when parents fail to appreciate the significance of symptoms, or when clinical and radiologic findings are misleading or overlooked by the physician.

I appreciated the excellent photograph of cutaneous leishmaniasis thatCPT Kenneth Brooks recently contributed to Photoclinic (CONSULTANT, June2004, page 1018, Figure).

What's the cause of a hyperpigmented patch on an adolescent boy's back?

A 16-year-old boy complains of an itchy scalp and areas of hair loss. Physical examination reveals a 2- to 3-cm patch of alopecia studded with black dots, as well as posterior cervical and occipital lymphadenopathy.

The lesion on this 6-year-old boy occupies almost the entire left side of his nose. The mother attributed it to an injury her son had sustained 2Z\x weeks earlier, when he was hit in the face by a baseball. The sharply defined, slightly elevated, pink macule had fine papules with an annular flat area at its inferior central aspect. A potassium hydroxide preparation of scrapings from the lesion was negative for hyphae. However, fungus culture grew Cladosporium species.

At that time, the patient's primary care physician had diagnosed Fifth disease. As the rash spread to the child's arms and back, atopic dermatitis was considered. The week before presentation in the ED, the rash had become more inflamed and pruritic and was accompanied by fevers.
