This infant was noted to have a giant melanocytic nevus at birth. Giant congenital melanocytic nevi (GCMN) can be recognized not only by their increased size (greater than 20 cm) but also by their increased cellularity and ability to affect deep dermal layers and other subcutaneous tissue. 1-4 Acquired nevi generally do not permeate the deeper dermal layers. Occasionally, GCMN may result in dysplasia of intraepidermal nevus cells, inflammatory spread of nevus cells, and proliferative dermal nodules.1
Pityriasis rosea had been diagnosed in this 10-year-old boy 3 months earlier. However, the condition had not resolved within that time as had been predicted. In addition, the patient’s parents noted that pictures of pityriasis rosea that they had found on the Internet did not resemble their child’s skin.
HISTORYBaby boy born at full term via forceps-assisted vaginal delivery to a 17-year-old primigravida was noted to have left arm and chest anomalies. Apgar scores 9 at 1 minute and 9 at 5 minutes. No pregnancy complications except for low amniotic fluid index. Second trimester ultrasonogram showed no malformations. At birth, infant was vigorous. He tolerated feeding well and passed urine and stool appropriately. Results of a hearing screen and newborn metabolic screen were normal. No family history of genetic disorders.PHYSICAL EXAMINATIONClinically, infant was asymptomatic. Vital signs normal. Weight, height, and head circumference (3.040 kg, 50.8 cm, and 33 cm, respectively) appropriate for gestational age. He had a flat left upper chest, an abnormal and caudally displaced left nipple, hypoplasia of the muscles of the upper left shoulder girdle and arm, significant shortening and bowing of the left forearm, and left hand cutaneous syndactyly. The left thumb resembled a finger and was not opposable. Heart sounds heard best to the right of midline, corresponding to dextroposition of the heart. No heart murmurs. Remaining physical findings unremarkable.WHAT’S YOUR DIAGNOSIS?(Answer and discussion on next page)ANSWER: POLAND SYNDROMEPoland syndrome, also known as Poland sequence, is a rare congenital anomaly characterized by unilateral chest wall hypoplasia and ipsilateral anomalies of the upper extremity. The condition, first described by Dr Alfred Poland in 1841, was officially named in 1962 by Dr Patrick Clarkson, who reported on 3affected children. The incidence of Poland syndrome is 1 per 20,000 to 30,000; however, it is believed to be underreported. The syndrome is 3 times more likely in males than in females; the right side is favored over the left.1ETIOLOGYDiminished blood supply to the affected side secondary to developmental defects of the subclavian artery is the suspected cause of Poland syndrome. Maternal drug abuse during pregnancy has been reported.2,3 Most cases of Poland syndrome arise sporadically. Familial cases have been described, which suggests some degree of genetic transmission. However, a case of Poland syndrome in one identical twin has been reported.4CLINICAL MANIFESTATIONSThe minimum criterion needed for diagnosis is unilateral absence or hypoplasia of the sternal portion of the pectoralis major muscle. Other classic features on the ipsilateral side include: •Hypoplasia or aplasia of the breast and nipple. •Deficiency of subcutaneous fat and axillary hair. •Abnormalities of the rib cage. •Upper extremity anomalies, such as short arm and fingers as well as syndactyly.2It is not rare for infants with Poland syndrome to have all the classic features. Intelligence is not impaired in children with this syndrome.
The most common chronic medical problem that we pediatricians treat is asthma. We do our best to manage our patients’ asthma by prescribing controller medications, providing asthma action plans, and guiding families through acute exacerbations. We often ask about possible environmental triggers, such as tobacco smoke and cockroaches, and we advise patients to reduce their exposure to those triggers.
The lesion on the left forearm of this 20-month-old girl developed shortly after birth and gradually worsened. The toddler scratched the lesion daily. It bled on occasion. The mother vigilantly kept the baby’s nails short and administered an oral antihistamine regularly. There was a family history of chronic eczema.

Sleep is an important, yet frequently underestimated component of adolescent health. Adequate sleep is essential for achieving maximal cognitive abilities as well as for maintaining the energy needed to meet the demands of a busy adolescent’s schedule. Lack of quality sleep can result in attention problems, cognitive dulling, various somatic complaints (such as headaches and abdominal pain), and mood disturbances.

Case: The parents of this 5-month-old boy are concerned about recurring eruptions of blisters on the infant’s hands and feet. What question could you ask the parents that might quickly define the condition for you?
Hypertrichosis refers to the increased growth of vellus or other hair at inappropriatelocations beyond the normal variation for a patient’s reference group.1 The affectedareas have a greater number of hair follicles than is normal for the body site.1 The condition is unrelated to androgen excess and unaccompanied by virilism or menstrual abnormalities.

Measurement of body mass index (BMI) is an effective way to screen for obesity and is an important part of the routine health evaluation of all children. A fasting blood sugar test is recommended for obese children 10 years and older who have a BMI above the 85th percentile for their age and sex and 2 high-risk criteria for diabetes (eg, positive family history or signs of insulin resistance). Patients with a BMI at the 85th percentile or higher also require screening for other comorbidities. Such screening includes measurement of waist circumference, blood pressure, lipid levels (specifically, levels of high- and lowdensity lipoprotein cholesterol and triglycerides, as well as total cholesterol), and liver transaminase levels.
A 13-year-old boy was brought to the emergency department (ED) with a generalized itchy rash of 2 days' duration.
