A patient (47-year old female) who had erythema similar to Gottron's sign on bilateral finger joints since two years ago, started to have polyarthralgia on bilateral knee and shoulder on the spring of 1993. Polyarthralgia was extended to both wrist and hand joints on Oct. of 1995. On the middle of Dec. 1995, she began to have exertional dyspnea and was referred and admitted in our hospital on 18th, Dec., 1995. Chest X-ray and CT scan showed the shadow for active interstitial pneumonitis on bilateral lower lung fields. Blood gas analysis indicated hypoxia (PaO2: 62.8 mmHg) and low % DLCO (64.7%). Skin eruption of face (heliotrope-like erythema) and hands (Gottron's sign) and skin biopsy (right hand) findings were compatible with that in dermatomyositis. The analysis in blood biochemistry showed no elevation for muscle enzymes. The diagnosis for amyopathic dermatomyositis (ADM) was made according to the criteria proposed by Euwer & Sontheimer (1993). The steroid pulse therapy and 50 mg per day of cyclophosphamide were immediately administered. The dyspnea and dermatitis were improved within two weeks after therapy. She is presently in remission until Jan. 1997 with the maintenance dosis of 10 mg per day of oral prednisolone.

A 47-year-old woman visited a clinic with dyspnea which had continued for two months and was followed by general fatigue and fever. Antibiotics were not effective. Edematous erythema occurred on her face, elbows, knees and feet, and she entered our hospital. A skin biopsy revealed interface dermatitis with severe edema and mucinosis in dermis. Diffuse bilateral infiltration was observed in the chest X-ray, and laboratory findings showed increased LDH, GPT, GOT and CPK. No antinuclear factor was detected. Her respiratory condition rapidly worsened, and she died eight days after hospitalization in spite of corticosteroid pulse therapy. The autopsy revealed that the main cause of death was diffuse alveolar damage (DAD). Interstitial pneumonia related to dermatomyositis is not histologically uniform; the response to the therapy depends on its histological type. The patients with dermatomyositis who have poor prognosis are clinically characterized by acute onset with general symptoms and less pronounced muscle weakness; they generally show DAD in their lungs. We need to establish a simple method for distinguishing histological types of interstitial pneumonia and adequate therapy for each one.

We describe a 32-year-old patient with adult dermatomyositis who developed dyspnea and worsening of pre-existing infarcted skin lesions of the fingers. Chest radiographs showed diffuse hazy reticulonodular infiltration in both lungs, subcutaneous emphysema, pneumomediastinum, and pneumothorax. The pulmonary symptoms and cutaneous lesions gradually improved with a high dose of prednisolone. Although subcutaneous emphysema and pneumomediastinum occur frequently in association with traumatic disruption of cutaneous and mucosal barriers and assisted ventilation, it has rarely been observed in patients with interstitial pneumonitis in connective tissue diseases. Although dermatomyositis and subcutaneous emphysema are all relatively well-known diseases to dermatologists, the occurrence of spontaneous pneumomediastinum and pneumothorax and subsequent subcutaneous emphysema in connective tissue diseases such as dermatomyositis is unfamiliar. We discuss the possible mechanisms of this condition.

We report a case of dermatomyositis (DM) associated with invasive thymoma in a 22-year-old woman who was admitted to our hospital complaining of dyspnea which required ventilation support. The reddened elevated scaly eruptions were prominent over the extensor surfaces. Chest X-ray and computed tomography showed mediastinal masses, which were diagnosed as mixed type thymoma. Muscle and skin biopsy specimens were compatible with DM. She was treated with methylprednisolone pulse therapy followed by extended removal of the anterior mediastinal tumor and subsequent radiotherapy. She has had a good clinical course without recurrence of thymoma or DM for more than 3 years. The role of thymoma in the development of DM is discussed.

A 46-year-old female was admitted to our hospital due to general fatigue, systemic edema and dyspnea with history of systemic sclerosis (SSc). The patient was diagnosed as mixed connective tissue disease (MCTD) based on Raynaud phenomenon, a high anti-RNP antibody level and clinical symptoms and laboratory findings suggesting SSc, dermatomyositis (DM) and systemic lupus erythematosus (SLE). After the admission, both alveolar hemorrhage and a rapidly progressive glomerulonephritis (RPGN) also developed and laboratory findings showed a positive remark of myeloperoxydase-antineutrophil cytoplasmic antibody (MPO-ANCA) and anti-glomerular basement membrane (GBM) antibody. She was therefore re-diagnosed as microscopic polyarteritis nodosa (microscopic PAN) combined with MCTD and treatment with high dose prednisolone and steroid pulse therapy dramatically improved general conditions and lung symptoms, but maintenance dialysis was persistent because of irreversible renal failure. However, 3 months after the admission, she died of acute exacerbation of interstitial pneumonitis that was unresponsive to steroid pulse therapy. Autopsy revealed interstitial pneumonitis with alveolar hemorrhage and crescentic glomerulonephritis (CrGN), in which immunofluorescent microscopy showed no deposition in agreement with pauciimmune type. The histological findings supported the diagnosis; primary microscopic PAN combined with MCTD, which is a quite rare case, to our knowledge. Furthermore, co-existence of MPO ANCA and anti-GBM antibody, clinical and histological findings of the case also lead us to reconsider the relevance of these antibodies to pathogenesis and/or categories of microscopic PAN and Goodpasture's syndrome.

A 59-year-old woman was admitted to our hospital with exertional dyspnea. Linear and reticular opacities in the middle and lower fields of both lungs were observed on chest roentgenograms and chest computed tomograms (CT). The presence of anti RNP-antibody and Raynaud's phenomenon, sclerosis of the fingers, and leukopenia yielded a diagnosis of mixed connective tissue disease associated with interstitial pneumonia. The symptoms and lung involvement were alleviated after the administration of prednisolone (40 mg/day). However, the patient experienced the sudden onset of dyspnea during pulmonary function tests. A chest X-ray film disclosed mediastinal air around the left pulmonary artery, and a chest CT scan demonstrated some blebs in the left lower lung field. After tapering the dosage of prednisolone in 5 mg increments per week, the pneumomediastinum disappeared without treatment. The clinical features and laboratory data findings suggested the patient's interstitial pneumonia was associated with systemic lupus erythematosus rather than with progressive systemic sclerosis or dermatomyositis. The pneumomediastinum may have been due to the rupture of blebs secondary to interstitial pneumonia during pulmonary function tests or as a result of steroid therapy.

We reported the case of a 39-year-old man with dermatomyositis (DM) complicated with subcutaneous emphysema and pneumomediastinum during steroid therapy. The patient had complained of muscle weakness, dyspnea and skin eruption on his anterior chest wall 6 months prior to admission. He was diagnosed as having DM on the basis of an elevation in myogenic enzymes, myogenic changes in electromyography, a skin biopsy and a muscle biopsy. Chest roentgenogram revealed interstitial pneumonia (IP) in the lower lobes of the lungs. The administration of prednisolone (60 mg/day) was initiated, which resulted in improvement of DM. Fifteen days after the initiation of the steroid therapy, the patient developed subcutaneous emphysema and pneumomediastinum. Additional administration of cyclosporin A (CsA) enabled us to rapidly taper the dose of prednisolone without aggravating the diseases. Several reports have shown that vasculitis might be involved in the pathogenesis of pneumomediastinum in DM patients. Infection and tissue fragility due to steroid therapy worsen the outcome of those patients. CsA therapy may improve the outcome through the anti-vasculitic- and steroid sparing-effects.

We describe a 42-year-old man with dermatomyositis and interstitial lung disease who presented with anterior neck pain and dyspnoea. Chest radiographs showed subcutaneous emphysema, pneumomediastinum and diffuse reticulonodular infiltration in both lungs. After the administration of high doses of prednisolone, an improvement of pulmonary function and respiratory symptoms was observed but the pneumomediastinum persists 12 months after diagnosis, and without any complication. We review the cases that have been reported thus far of pneumomediastinum associated with dermatomyositis and discuss the possible mechanisms involved. We conclude that pneumomediastinum is not an uncommon complication of dermatomyositis and that its aetiopathogenesis remains very unclear.

We report findings in 70 patients with both diffuse interstitial lung disease and either polymyositis (PM) or dermatomyositis (DM). Initial presentations were most commonly either musculoskeletal (arthralgias, myalgias, and weakness) or pulmonary (cough, dyspnea, and fever) symptoms alone; in only 15 patients (21.4%) did both occur simultaneously. Pulmonary disease usually took the form of acute to subacute antibiotic-resistant community-acquired pneumonia. Chest radiographs and computed tomography most commonly demonstrated bilateral irregular linear opacities involving the lung bases; occasionally consolidation was present. Jo-1 antibody was present in 19 (38%) of 50 patients tested. Synchronous associated malignancy was present in 4 of 70 patients (5.7%). Surgical lung biopsies disclosed nonspecific interstitial pneumonia (NSIP) in 18 of 22 patients (81.8%), organizing diffuse alveolar damage (DAD) in 2, bronchiolitis obliterans organizing pneumonia (BOOP) in 1, and usual interstitial pneumonia (UIP) in 1. Treatment usually included prednisone in 40-60 mg/d dosages for initial control, followed by lower dose prednisone plus an immunosuppressive agent such as azathioprine or methotrexate for disease suppression. Survival was significantly better than that observed for historical control subjects with idiopathic UIP, and was more consistent with survival previously reported in idiopathic NSIP. There was no difference in survival between Jo-1 positive and Jo-1 negative groups.

The anti-synthetase syndrome comprises the association of an inflammatory myopathy (polymyositis, dermatomyositis), interstitial pneumonitis, skin lesions characteristic of "mechanics hands", Raynaud's phenomena, inflammatory polyarthritis and, at the biological level, antinuclear antibodies known as anti-synthetases. We report our observations of two patients, one with a typical anti-synthetase syndrome and one with an incomplete form. Two men aged 49 and 47 presented with increasing dyspnoea upon effort, muscular weakness, arthralgia, bilateral pulmonary crackles and, in the first case, typical hairless skin lesions. In both cases the chest x-rays and CT scans confirmed the presence of interstitial lesions, predominantly in the lower lobes. Lung function tests showed a restrictive pattern with reduced gas transfer. At the biological level both patients presented an inflammatory picture with elevated muscle enzymes and anti-Jo-1 antibodies. Immuno-suppressive treatment with cortico-steroids and cyclophosphamide lead to a symptomatic improvement, regression of the radiological changes and improvement in the measurements of pulmonary function.
