Proptosis is a frequent presenting symptom/ sign of many pediatric malignancies. Acute onset proptosis is an oncological emergency that can endanger vision if not treated promptly. Appropriate treatment must be instituted only after investigating for the underlying etiology. Here we report a 6-year-old developmentally delayed boy who presented with recent onset bilateral proptosis. Clinical examination followed by radiological evaluation suggested scurvy to be the underlying cause and vitamin C supplementation lead to prompt reversal of proptosis. The relevant literature has been reviewed and presented here to apprise the pediatric oncologists about this rare but easily treatable cause of proptosis.
