Myoglobinuria was found in an 11 month old girl suffering from fever, dyspnoea, and muscle hypotonia. Muscle biopsy showed focal degenerative necrosis of the muscle fibres. Electronmicroscopically, picornavirus-like crystals were demonstrated in the muscle fibres. These and other findings strongly suggest that she suffered from acute myositis with myoglobinuria probably caused by Coxsackie B6 virus infection. The causal relationship of viral infection (Coxsackie, influenza, or myxo-viruses) and acute or chronic polymyositis with or without myoglobinuria is discussed.

We describe a case of idiopathic hypereosinophilic syndrome manifested by an axonal sensory-motor polyneuropathy (ASMP) and signals of myositis. A 20 year old woman began with progressive gait impairment with drops and presented with subacute lower limb edema associated with paresthesis and cramps. She showed hypotonia in the lower limbs, absence of knee and ankle jerks, steppage gait, and decreased sensation on both legs. Examinations of stools were negative. Blood examination showed 7700 leukocytes with 24% (1848/mm(3)) eosinophils. Electrodiagnostic studies showed axonal lesion in sensory and motor nerves. Muscle biopsy showed type 2 muscle fibers atrophy with discrete inflammatory cells, predominantly lymphocytic in perivascular and interstitial locations. She was treated with prednisone and all the symptoms subsided after two months.
