Hyperpigmentation in a child as a clue to chikungunya
Sanjanaa Srinivasa, Sumedha Ballal Dear Editor,
A 2-month-old male child born of non-consanguineous marriage presented with high-grade, intermittent fever for 1 month along with history of reduced feeding and lethargy for 2 days. The birth weight of the child was 2.5 kg. The mother observed pigmentation initially appearing over the face, which progressively extended to involve the rest of the body for 20 days. All milestones were appropriate for age.
On examination, diffuse macular brownish-black pigmentation was observed over the nose, perioral area, periphery of the face, trunk, and extremities and. Differentials thought of were Vitamin B12 deficiency, Addison’s disease, congenital adrenal hyperplasia (CAH), and chikungunya.
