Primary hypertriglyceridemias are very rare in pediatric age group. A case of 12 years old boy with hypertriglyceridemia is presented. He was being treated as a case of thalassemia major since 2 years of age and was picked up incidentally when his serum turned milky on standing. Since hypertriglyceridemia is a known risk factor for the acute pancreatitis so an early detection is helpful in adoption of a healthy life style.
