We describe a case of vitamin-D-deficiency rickets in a
young child to highlight its existence in Malaysia where
sunlight is abundant throughout the year. The child
presented with deformity of both legs. He came from an
educated urban family but remained indoors most of the
time. Radiographs of knees and wrists showed changes of
florid rickets. Low serum 25-hydoxyvitamin-D, high
parathyroid hormone, normal serum phosphate and calcium
levels, and normal renal function clinched the diagnosis of
vitamin-D-deficiency rickets. He improved remarkably after
treatment with oral Vitamin-D. We emphasise the importance
of exposure to sunlight to prevent rickets.
