Primary varicella infection is rarely complicated by rhabdomyolysis. In this study, we describe a case of rhabdomyolysis complicating a VZV infection in a black subject. The patient was a 24-year-old black African with no particular medical history and was immunocompetent. He presented with an acute onset of generalized rash, fever, and generalized weakness. Physical examination revealed vesicular lesions typical of chickenpox. Antipyretic treatment combined with acyclovir was instituted in hospital. At the 72nd hour, diffuse myalgia developed. Muscle enzyme tests revealed CPK elevated to 40 times the upper limit of normal, LDH elevated to 2 times the upper limit of normal, ASAT and ALAT elevated to 7 times the upper limit of normal, and 2.5 times the upper limit of normal, respectively. We accepted the diagnosis of rhabdomyolysis secondary to VZV infection. The patient was given saline hydration and showed clinical and biological improvement 1 month later. A patient presenting with muscular symptoms during a VZV infection should be considered for rhabdomyolysis.
