This report emphasizes the importance of considering BTH in the differential diagnosis of elevated ALP and presents a case in light of the current literature. Recognition of BTH is crucial to prevent unnecessary investigations and referrals in pediatric practice. KW - Benign transient hyperphosphatasemia KW - children KW - alkaline phosphatase N2 - Benign geçici hiperfosfatazemi (BGH), erken çocukluk döneminde görülen, altta yatan herhangi bir hastalık bulgusu olmaksızın serum alkalen fosfataz (ALP) düzeylerinde geçici yükselme ile karakterize, kendini sınır- layan bir durumdur. Bu olgu sunumu, artmış ALP düzeylerinin ayırıcı tanısında BGH’nin göz önünde bulun- durulmasının önemini vurgulamakta ve mevcut literatür ışığında bir olguyu sunmaktadır. BGH’nin tanınması, çocukluk çağında gereksiz tetkik ve yönlendirmelerin önlenmesi açısından büyük önem taşımaktadır. CR - 1.
