The aspiration cytologic finding of myositis ossificans is not well documented but similar to that seen in nodular fasciitis except less cellularity. Myositis ossificans is a reactive condition that is sometimes mistaken microscopically for extraosseous osteosarcoma. Cytologically, myositis ossificans may be distinguished from extraosseous osteosarcoma by the presence of uniform benign stromal cells composed of mature fibroblasts and osteoclastic giant cells. However, the differential diagnosis may be difficult in the early stage of this reactive and proliferative process. We recently experienced a case of myositis ossificans. The patient was a 67-year -old woman with painful swelling of the left index finger for one month. Simple x-ray finding showed a soft tissue mass with calcific center at middle phalanx of the left hand. Fine needle aspiration cytology revealed a few individual or clusters of spindle cells in dense eosinophilic stroma with osteoclastic giant cells. The spindle cells were uniform smooth-bordered, and oval nuclei with single small inconspicuous nucleoli, and elongated cytoplasm. The scattered individual cells had eccentric nuclei with one or two nucleoli and abundant, basophilic cytoplasm.

Polymyositis is diffuse, inflammatory myopathy with proximal-muscle weakness due to lymphocyte infiltration to the muscle layer. The exact cause of the muscle weakness is unclear but may be related with an immunologic mechanism. Using high-dose steroid is the treatment of choice for polymyositis. It is difficult to distinguish steroid-resistant polymyositis from steroid myopathy, however, in the course of high-dose steroid therapy. These authors encountered a steroid myopathy patient during polymyositis treatment with high-dose steroid. A 57-year-old woman was diagnosed with polymyositis and was treated with high-dose steroid. Her condition was initially improved, but in the course of the treatment, her symptom was aggravated without increasing the muscle enzymes. Her muscle weakness was improved by reducing the steroid dosage.

Purpose: Myositis ossificans is a benign condition of heterotopic bone formation that still requires more of its pathologic explanation. The lesions are localized predominantly to the high-risk sites of injury, involving flexor muscles of the upper limbs and thigh, but rarely in the head and neck area. Methods: A case of a 44-year-old male patient presented with a palpable hard mass on nasal dorsum. The patient experienced a similar lesion on upper limb few years ago. On computed tomographic image, the lesion presented focal definite increase in opacity compatible to adjacent bone densitiy on nasal dorsum. Results: The lesion was excised under open rhinoplasty incision. The pathologic report revealed focal bone formation and calcification within skeletal muscle. Conclusion: We describe a unique and only case of a myositis ossificans on nasal dorsum which is indifferent from previous concept.

To evaluate the diagnostic usefulness of radioisotope bone scan and clinical activity of myositis, bone scan using $^{99m}Tc-Methylene$ diphosphonate was serially done before and after treatment with prednisolone in 10 patients with well-documented dermatomyositis-polymyositis. The observed results were as follows. 1. In all 10 patients before treatment with prednisolone, the bone scans showed evidence of increased muscle uptake. Muscle uptake was markedly increased in 4 patients, moderately increased in 3 patients and minimally increased in 3 patients. 2. The site of increased muscle uptake was consistent with the site of clinically involved muscle which was weak and tender. 3. The degree of muscle uptake correlated with the severity of the muscle weakness and tenderness at the scan was done. In all 10 patients treated with high dose prednisolone, muscle uptake was decreased following therapy. Above results suggest the radioisotope bone scanning may be useful in the diagnosis and treatment of patient with dermatomyositis-polymyositis.

Myositis ossificans is a condition characterized by ossification within a muscle. It is a rare and unusual pathologic entity that has defied medical efforts to establish a definite etiology, pathogenesis, and satisfactory treatment of the disease. The condition predominantly affects the flexor muscles of the upper limbs and thighs, but rarely the head and neck area. A 53-year-old male patient visited our medical institution complaining of trismus, defined as limited mouth opening. The patient had a history of trauma to the facial bones and the computed tomography scans revealed calcification in the left temporalis muscle. The patient underwent surgical removal of the calcified mass with bilateral coronoidectomy under general anesthesia. Mouth opening at the end of post-operative 2 months was 28 mm. His oral intake of food was satisfactory. Myositis ossificans of the temporalis muscle is a very rare case. Satisfactory outcome was obtained by combining surgical excision of the affected muscle, coronoidectomy, and detachment of the insertion site of the ossified muscle.

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.

Interstitial pneumonitis may be the presenting manifestation of polymyositis-dermatomyositis (PM-DM), or may occur later in the evolution of disease. The clinical picture is characterized by non-productive cough, dyspnea and hypoxemia. The chest radiograph demonstrates interstitial infiltrates with predilection for the lung bases, often with an alveolar pattern in addition. We experienced a case of polymyositis associated with diffuse alveolar damage(DAD) that was proven in open lung biopsy. The patient was a 52 year-old woman who was presented with 6 months' duration of generalized ache, edema on ankle and wrist, non-productive cough and mild dyspnea. She had typical symptoms and physical findings of interstitial pneuminitis, and elevated muscle enzyme levels in serum with characteristic histologic findings of myositis on muscle biopsy. She also had typical interstitial lung disease pattern on high resolution CT and restrictive pattern on pulmonary function tests. The findings of open lung biopsy was compatible with diffuse alveolar damage(DAD). She failed to respond to the therapeutic trials with corticosteroid and cyclophosphamide, and finally expired due to acute respiratory distress syndrome.

Objectives : Polymyositis is non-hereditary, autoimmune rheumatic disease, and one of the idiopathic inflammatory myopathy. It is characterized by progressive symmetrical proximal muscle weakness. Major clinical signs and symptoms of polymyositis are chronic non-suppurative inflammatation of skeletal muscle, elevation of muscle enzyme, and electromyographical changes. By use of Korean medicine treatments, muscle weakness and normalize muscle enzyme can be improved in case of polymyositis. Methods : A Patient, 32 years old, whom diagnosed with polymyositis on muscle biopsy and electromyographical changes, had medical treatments with Corticosteroids and Immunosuppressants, but no improvement was noted. She was treated with Korean Medicine, especially Ohaeng-Hwa Acupuncture(五行和 鍼法) and Ssanghwa-Tang(雙和湯) for three months period. Results : With Korean Medicine treatment of polymyositis for three months, most of her clinical signs and symptoms have been improved significantly, especially her muscle weakness and muscle enzyme level. Conclusion : This case has been reported to show that Korean medicine treatments have positive effects on polymyositis.

Taking history and ultrasonography is important to detect foreign body which might be located in the soft tissue. We encountered a case of soft tissue foreign body (transobturator tape) in a patient who had been treated with the impression of adductor myositis resulting from vagina fistula. The foreign body was found through ultrasonographic examination and the patient's symptom was relieved after removal of the foreign body from the ultrasonography-guided operation. Clinicians should keep in mind the fact that foreign bodies may exist when the inflammation persists without appreciable cause and ultrasonography can be useful tool in case of small fibrous band not detected with magnetic resonance imaging due to inflammatory change of the surrounding tissues.
