INTRODUCTION Myositis ossificans is a benign, self-limiting condition that usually affects young, athletically active men. To the best of our knowledge, this case report describes the oldest recorded patient with myositis ossificans. CASE PRESENTATION Our patient was an 83-year-old Japanese woman who presented with a one week history of a palpable mass in the left thigh. She had a history of ...

plastic formation of heterotopic bone in the skeletal muscle (1-5). Although myositis ossificans can occur anywhere in the body following trauma, it is predominantly localized to high-risk sites of injury, such as large muscles of the extremities (2-4). Most lesions are related to direct major trauma or repeated minor injuries. No history of trauma is present in approximately 40% of patients (2...

Historically, first case of TP was described by Scriba in 1885, though some authors believe that Virchow was the first one to describe this entity. Since TP was predominantly seen in tropics, various terms like tropical pyomyositis, myositis tropicans, and tropical myositis are used, but nowadays this entity is no longer confined only to tropics. Levine in 1971, reported the first case of TP fr...

INTRODUCTION Myositis ossificans is a benign, self-limiting, tumor-like lesion that usually affects the elbow and thigh; occurrence in the hand is uncommon. We report a rare case of a patient with myositis ossificans in the thenar region. CASE PRESENTATION A 15-year-old Japanese girl presented to our hospital with a 2-month history of a painful mass in the right thenar region without previous...

Chronic inflammation of skeletal muscle tissues, termed myositis, is associated with inherited muscular dystrophy and acquired inflammatory myopathy. In this review, the role of the organic osmolytes taurine, betaine, myo-inositol, and sorbitol in skeletal muscles in general, and in myositis in particular, is discussed. Evidence indicates that regulated osmolyte pathway activation contributes t...

INTRODUCTION Recurrent myositis triggered by infections is unusual, with only one other case reporting two attacks described in the literature. CASE PRESENTATION We report the case of a 24-year-old Caucasian woman with recurrent myositis triggered by sore throat, respiratory and urinary tract infections, over the past 18 years, up to four times a year. Myositis of this frequency and duration,...

Inflammatory myopathies are a heterogeneous group of acquired systemic diseases, which include dermatomyositis (DM), polymyositis (PM), necrotising myopathy (NM) and inclusion body myositis (IBM). All four disease entities share certain clinical characteristics, such as progressive muscle weakness and elevated muscle enzymes. Other characteristic-associated features such as skin involvement in ...

The discovery of unique autoantibodies has informed and altered our approach to the diagnosis and management of the inflammatory myopathies. This study reports the initial clinical experience of use of the Extended Myositis Antibody (EMA) panel in the largest university teaching hospital in Ireland. We conducted a retrospective review of all patients who had serum samples tested for myositis sp...

We report a 9-year-old Japanese girl who presented with muscle weakness and elevated serum levels of muscle-derived enzymes following mycoplasma infection. Rhabdomyolysis or myositis was suggested by magnetic resonance imaging and repeated four times within 4 years. Each episode developed following respiratory infection and spontaneously recovered. The diagnosis of Sjögren’s syndrome was made b...
