Symmetrical proximal weakness and characteristic dermatologic manifestations are important in the diagnosis of dermatomyositis. We report a case of atypical presentation of dermatomyositis due to previous steroid use and also report steroid-induced myopathy which may occur from steroid administration during the course of treatment. A 77-year-old man, previous steroid user, showed rapidly progressing weakness after abruptly stopped medication. He has presented erythematous papule on face and anterior chest but no heliotrope rash and Gottron's papules were observed. Muscle enzyme (creatine kinase) concentration is increased, and needle electromyography shows increased spontaneous activity on proximal limb muscle. The muscle biopsy confirmed dermatomyositis. During the course of treatment, he revealed persistent weakness despite the continuous steroid use and stable creatine kinase level. Electrodiagnostic study suggests steroid-induced myopathy and after tapering steroid, proximal muscle strength improved. This case reports the effect of steroid use on dermatomyositis patients and a process of diagnosing coexisting steroid induced myopathy during treatment.

Objective : The purpose of this study is to report the improvement after the acupuncture therapy and herbal medicine about a patient who has latrogenic Cushing with steroid induced myopathy and compression fracture of L-spine. Methods : We treated the patient with Neutral Blood Stasis herbal acupuncture, acupuncture therapy and herbal medication. Results : We have experienced one case of latrogenic Cushing syndrome with steroid induced myopathy and compression fracture of L-spine. This case improved significantly through acupuncture and herbal medication treatment. Conclusions : This study suggests manual acupuncture therapy and herbal medication is effective for the improvement of latrogenic Cushing syndrome with steroid induced myopathy and compression fracture of L-spine.

Among drug-induced myopathy, steroids are probably the most common cause. The risk of steroid myopathy(SM) increases with the dose and duration of use. It is typically a proximal myopathy, preferentially affecting the hip girdle muscles. Motor and sensory nerve conduction studies are normal. The needle EMG is usually within the normal range or may be minimally abnormal. Occasionally, low-amplitude, short-duration MUAPs may be seen in the proximal muscles. Of note, abnormal spontaneous activity is not seen. This point is often very useful in differentiating polymyositis(PM) from SM. It is common for patients with PM to be treated with steroids, respond well, and then have the steroids tapered. If muscle weakness then returns, it may be very difficult to differentiate recurrent PM from SM on clinical grounds. The presence of abundant abnormal spontaneous activity strongly suggests PM rather than SM.
