Chronic graft-vs.-host disease (cGVHD) occurs in 20-50% of patients who survive for at least 100 d after allogeneic stem cell transplantation (SCT). cGVHD includes scleroderma-like skin changes, chronic cholangitis, obstructive lung disease and general wasting syndrome. Polymyositis or myopathy are rare manifestations of cGVHD with approximately 40 reported cases. Polymyositis accompanied by hemosiderin deposits in cGVHD has been reported only once, and there are no reports on lipofuscin deposits in skeletal muscle cells in cGVHD. We report here on a 56-yr-old male who underwent allogeneic SCT in 1999 for osteomyelofibrosis and progressive hematopoietic insufficiency. In February 2004, the patient was hospitalized for progressive muscular weakness with loss of the ability to walk. Laboratory tests demonstrated normal values for serum creatine kinase, aldolase and lactic dehydrogenase; the ferritin level was highly elevated. The femoral muscle biopsy showed mostly perifascicular atrophy as well as numerous subsarcolemmal hemosiderin and lipofuscin deposits. Intravenous administration of the chelating agent deferoxamine was ineffective. Three weeks later the patient died of aspiration pneumonia. Interestingly, autopsy disclosed moderate hemosiderin deposits in the liver, the organ usually involved in hemosiderosis.

Polymyositis and dermatomyositis are systemic inflammatory diseases with unknown etiology and prognosis. Pulmonary involvement is increasingly recognized to be a major complication and a common cause of morbidity and mortality in these diseases. Thus a thorough pulmonary evaluation is necessary to permit appropriate management. There are three categories of pulmonary complications in myositis: aspiration pneumonia, hypoventilation, and interstitial lung disease (ILD). ILD is a frequent pulmonary complication in patients with myositis, and respiratory symptoms are not reliable signs for diagnosis. The strongest predictive factor for ILD in patients with myositis is the presence of antihistidyl transfer ribonucleic acid (tRNA) synthetase antibodies (anti-Jo-1), but ILD may also be present in patients without these autoantibodies. Therefore, all patients with polymyositis or dermatomyositis should be investigated with chest radiography, high-resolution computed tomography, and lung function tests.

A three-year-old, 7.3-kg, female Pembroke Welsh Corgi exhibited symptomatic tongue atrophy, crinkling of the tip of the tongue, dysphagia and excessive salivation. Neurological examination suggested multiple cranial neuropathy, but polymyositis was diagnosed by magnetic resonance imaging and muscle biopsy. The dog did not respond to prednisolone treatment and died from aspiration pneumonia 22 months after the first presentation. Post-mortem histopathological examination of the tongue revealed marked myofiber loss and fibrosis with multifocal infiltration of mixed mononuclear cells. Similar findings were also observed in the masticatory muscles and quadriceps without abnormality of peripheral nerves or evidence of infection. Symptomatic tongue atrophy occurring in the course of polymyositis has not been reported previously in dogs.

A 32-year-old man, who had been diagnosed with left testicular tumor and treated surgically at 30 years old, was diagnosed with recurrence of the testicular tumor by the elevation of tumor markers and para-aortic lymph node enlargement on computerized tomography. At the same time, creatine kinase was extremely elevated and he was diagnosed with polymyositis (PM). After systemic chemotherapy, the tumor markers improved. The symptoms of myopathy, however, became so severe that he developed aspiration pneumonia and required the temporary use of a ventilator. Using intravenous immunoglobulin and steroid pulse, the symptoms of PM improved. After the third chemotherapy session, the testicular tumor was in complete remission and he had no symptoms of polymyositis. After follow up for 7 years, there was no sign of recurrence of either testicular tumor or PM.

Polymyositis is an idiopathic inflammatory myopathy of unknown aetiology that affect skeletal muscles causing symmetrical, proximal muscle weakness, and also other internal organs. The investigations reveal elevated skeletal muscle enzyme levels and characteristic electromyography (EMG) and muscle biopsy findings. Pulmonary involvement in polymyositis includes respiratory muscle weakness, aspiration pneumonia, interstitial lung disease, infection and drug-induced pneumonia. We expose the case of a young woman (47 years old) who presented to the Pulmonology Clinic with fever, cough, purulent sputum, discrete myalgia, being diagnosed at that moment with interstitial lung disease and treated with antibiotics, low dose of corticosteroids and symptomatic drugs. The evolution was slowly favorable for the respiratory impairment, but the patient developed exacerbated myalgia, muscle weakness, reaching even the impossibility of maintaining orthostatism, and also joint pain. Biological investigations revealed an important hepatocytolysis syndrome and also increased levels of muscle enzyme. The hypothetical diagnosis was polymyositis and to sustain this theory it was performed a muscle biopsy. The patient was transferred afterwards to the Rheumatology Clinic, in order to perform other specific investigations. In our clinic the patient maintained elevated levels of skeletal muscle enzymes and the muscle biopsy revealed polymyositis findings. Also immunological investigations objectified the presence of Jo1 antibodies. Therefore we pleaded for the diagnosis of idiopathic polymyositis, acute form. A multidisciplinary approach is needed in order to establish an accurate diagnosis and to institute a proper treatment.
