Terms such as march hemoglobinuria foot strike hemolysis and runners hemoglobinuria have previously been coined and are easily recalled. Newer cases however are being identified in individuals vigorously using their upper extremities such as drum players who use their hands to strike the instrument. Given the increased recognition of upper extremity-related mechanical hemolysis and hemoglobinuria in drummers and the use of hand drumming worldwide we would like introduce a novel term for this condition and call it percussion hemoglobinuria . Case presentation A 24-year-old Caucasian man presented with reddish brown discoloration of his urine after playing the djembe drum. Urine examination after a rigorous practice session revealed blood on the dipstick and 0 to 2 red blood cells per high power field microscopically. The urine sample was negative for myoglobulin. Other causes of hemolysis and hematuria were excluded and cessation of drum playing resulted in resolution of his symptoms. Conclusions The association of mechanical trauma-induced hemoglobinuria and playing hand percussion instruments is increasingly being recognized. We however feel
