Overview
Other Diagnostic Studies
- Electromyogram may be helpful in the diagnosis of polymyositis and dermatomyositis. Findings suggestive of polymyositis and dermatomyositis include:[1]
- Electromyogram may also be used to
- Identifying active sites of myositis for biopsy
- Follow up the treatment efficacy. The first sign of improvement in polymyositis and dermatomyositis is the disappearance of fibrillation potentials.
- Exclude all the other causes of denervations
- Skin biopsy may be used in dermatomyositis,which demonstrates:
- Poikiloderma
- Epidermal atrophy
- Liquefaction degeneration of the basal cells
- Vascular dilatation
- Lymphocytic infiltration of the dermis
- Other diagnostic studies for [disease name] include:
- Histochemical staining, which differentiate polymyositis and dermatomyositis from lower-motor-neuron diseases.
- Skin biopsy, which demonstrates:
- [Finding 1]
- [Finding 2]
- [Finding 3]
