Abstract

Bening transient hyperphosphatasemia of childhood is a harmless clinical condition without exactly determined etiology, characterized by 3-50 fold increased serum alkaline phosphatase (ALP) levels, generally encountered under 5 years old. Patients have no evidence of bone or liver disease. However, this excessive increase may disturb clinicians and families. The high ALP levels turn normal in 2-6 months spontaneously in most of the cases. In this report we present a 3,5 years old boy with serum ALP elevation up to 2679 IU/L, determined incidentally during acute gastroenteritis. Serum ALP level returned normal within 3 weeks in our case.
