Transient Zinc Deficiency in a 5-month-Girl: When Breast Milk is the Culpable

Diversification of the child's diet and dietary counseling for the mother are crucial to prevent zinc deficiency. Regular follow-ups with dermatological and nutritional assessments are recommended to monitor for any recurrence of symptoms. A 5-month-old girl presented with a 2-week history of persistent and intractable skin lesions. She was treated initially with emollients and dermo corticoids but with no improvement. The analysis of the mother's breast milk revealed low zinc levels, providing additional support for the diagnosis. Zinc deficiency in lactating mothers can occur due to various factors, including dietary intake, maternal zinc status, and the concentration of zinc in breast milk. Early recognition, timely laboratory investigations, and appropriate treatment are crucial for optimal outcomes. Healthcare professionals should consider the diagnosis, especially when confronted with characteristic skin lesions.
