Diabetes in young--unusual case presentation.

Diabetes in young is increasing in prevalence with each decade. Phenotypic features like obesity and acanthosis nigricans characterize type 2 diabetes, whereas autoimmune diseases like vitiligo and hypothyroidism suggest type 1 diabetes. We recently encountered a young boy with vitiligo who presented with hyperglycemia, but not associated with ketonuria and has underlying chronic pancreatitis with secondary diabetes. We report the case for its unusual presentation and etiology of the diabetes.
