Idiopathic inflammatory myopathies (IIM), or myositis, are a heterogeneous group of autoimmune disorders that can affect multiple organs, including the muscles, skin, joints, lungs, heart, and gastrointestinal tract. While new-onset myositis has been reported following SARS-CoV-2 infection, cases associated with COVID-19 vaccination remain rare. We describe a unique case of severe progressive edematous facial myositis resembling angioedema in a 22-year-old man, with onset one to two weeks after receiving dual SARS-CoV-2 and influenza vaccinations.

The primary etiology of pyomyositis is predominantly , although Gram-negative bacteria may also be involved on rare occasions. The prognosis for pyomyositis caused by Gram-negative bacteria is more unfavorable than that of infections caused by Among Gram-negative bacteria, members of the Enterobacteriaceae family, including , species, and species, have the capacity to produce gas. Gas-forming myositis is a rare phenomenon that primarily affects immunocompromised patients and is associated with a poor prognosis.

Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening condition which can present with hemoptysis, diffuse alveolar infiltrates, anemia, and hypoxic respiratory failure. Antisynthetase syndrome (AS) is a rare autoimmune disorder most often characterized by nonerosive arthritis, proximal muscle weakness with elevated muscle enzymes, Raynaud's phenomenon, hyperkeratosis of the digits (mechanic's hands), and interstitial lung disease. According to large population studies, AS has an annual incidence of 0.

The combination of severe myalgia, progressive weakness, and blood in the urine often leads a neurologist to consider myositis. Accordingly, reddish urine may be linked to urine myoglobinuria brought about by muscle destruction. Nevertheless, in a young patient with normal creatine kinase complaining of immobility, adult-onset Still's disease (AOSD) should be one of the top differentials.
