Zorluk: OrtaNeonatal Disorders

During a routine well-child evaluation, the parents of a 21-day-old boy express concern regarding a progressive skin eruption on his face that began five days ago. The infant was born at 39 weeks gestation via uncomplicated spontaneous vaginal delivery to a 28-year-old primigravida. His birth weight was 3.4 kg (7 lb 8 oz), and Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. The mother received standard prenatal care, and maternal group B Streptococcus screening was negative. The parents report that the infant is exclusively breastfed, latching well, and stooling normally without any episodes of emesis. He has had no fevers, irritability, or changes in his level of activity. Vital signs today show a rectal temperature of 37.1°C (98.8°F), heart rate of 135/min, and respiratory rate of 40/min. Physical examination reveals an alert, vigorous, and well-hydrated neonate. Skin examination is notable for numerous small, erythematous inflammatory papules and pustules strictly confined to the forehead, nose, and bilateral cheeks. There are no comedones present. The scalp, neck, trunk, and extremities remain clear. Which of the following is the most appropriate next step in management?

  1. Reassurance and routine skin cleansingCevap
  2. B
    Admission for intravenous acyclovir therapy
  3. C
    Swab of the lesions for bacterial Gram stain and culture
  4. D
    Application of topical mupirocin ointment
  5. E
    Application of topical hydrocortisone cream

Cevap

Reassurance and routine skin cleansing
The correct answer is reassurance and routine skin cleansing. This patient's presentation of inflammatory papules and pustules strictly on the face, appearing around 3 weeks of age without comedones in an otherwise healthy and well-appearing infant, is the classic presentation of neonatal cephalic pustulosis (formerly known as neonatal acne). The condition is thought to represent an inflammatory response to Malassezia species colonization. It is a benign, self-limited eruption that typically resolves without scarring over several weeks to months. The diagnosis is clinical, and no laboratory evaluation or aggressive medical intervention is necessary. Routine skin care with daily cleansing using water and a mild soap is the only recommended management for mild to moderate cases. Topical antifungal therapy, such as ketoconazole cream, is reserved only for severe, extensive, or prolonged cases.

Adım Adım Çözüm

1
Analyze the patient's demographic and clinical presentation.
The patient is a well-appearing 3-week-old boy with a 5-day history of facial inflammatory papules and pustules lacking comedones, without any systemic symptoms.
Identifying the specific age of onset, lesion morphology, and absence of systemic signs is critical for differentiating benign neonatal rashes from infectious etiologies.
2
Formulate a diagnosis based on the clinical findings.
The diagnosis is neonatal cephalic pustulosis (previously known as neonatal acne).
The timing (around 3 weeks of life), specific location (cheeks, forehead, nose), and lesion type (papules and pustules without comedones) in a healthy infant are classic for this condition, which is an inflammatory reaction to Malassezia species.
3
Determine the most appropriate management for this condition.
Select reassurance and routine cleansing.
Because neonatal cephalic pustulosis is a benign, self-limited condition that typically resolves within weeks to months without scarring, conservative management with daily washing using mild soap and water is the standard of care.

Neonatal cephalic pustulosis is a benign, self-limited papulopustular eruption that presents in the first few weeks of life; it requires only clinical diagnosis, reassurance, and routine skin cleansing.
