Focal myositis – http://id.who.int/icd/entity/708931518

Focal myositis is an idiopathic inflammatory myopathy that appears clinically like a muscular tumefaction that is solitary, painful, bleeds occasionally and is usually located in the musculature of the lower limbs. Its rapid enlargement simulates that of a soft tissue tumour. This disorder may remit spontaneously, remain focal and confined to one limb for several years, or, in an unusual form of polymyositis, progress to a more typical distribution after a few days or weeks.
