A 7-year-old patient presented with a 1-month history of rhinitis, cough, low-grade fever, and bright, patchy erythema on his cheeks and chin. The rash did not respond to treatment with halometasone cream or betamethasone dipropionate cream with gentamycin sulfate. His medical history was noncontributory, and his parents were nonconsanguineous and in good health
On physical examination, erythematous plaques were evident on the patient’s cheeks and chin (Figure 1). He also had onychoschizia of some fingernails (Figure 2). The results of bacterial and mycological culture of facial skin were negative. A punch biopsy specimen was obtained from an erythematous plaque on the face (Figure 3).
