Vitamin D deficiency rickets has multiple aetiologiesin infants in the tropics and regions of abundant sunlight. The reduced intake of vitamin D frombreastmilk in mothers with vitamin D deficiency and absence of Vitamin D supplementation are common causes. Reports have shown vitamin D deficiency to be a rare underlying cause of rickets in Nigerian children a region with abundant sunlight. Here is a rare presentation of progressive painless wrist swelling in an 11months oldinfant with radiologic features and biochemical deficiency of Vitamin D in mother infant pair and marked reduction in sunlight exposure. Mother manifested features of possible osteomalacia in pregnancy, did not receive vitamin D supplements during pregnancy and after delivery, She also received little or no sunlight due to change in lifestyle as she stayed indoors with baby. This report therefore reveals risks factors for vitamin D deficiency in a region with abundant sunlight.
