[Biceps crural myositis after an insect bite].

INTRODUCTION

It can be difficult to diagnose focal muscular disease. We report a case of crural biceps focal myositis after an insect bite.

DISCUSSION: We then discuss diagnostics of one or a small number of muscle injury. Focal inflammatory myositis has been described. We emphasize the role of pathology. In our case, pathological examination rules out inflammatory or tumoral disease and access likely toxical etiology. Muscle injury can appear, most frequently around the bite of venomous animal.

CONCLUSION

Hymenopters are often responsible for such stings in France. Venoms are toxic for muscle cells membrane.
