Pyomyositis is a primitive infection of the skeletal muscle usually caused by Staphylococcus aureus in tropical areas, and associated with immunodeficiency. We report a 49-year-old immunocompetent woman, living in a temperate climate presenting with a pyomyositis of adductor muscles caused by Escherichia coli. ⋯ Disease course was uneventful after surgical debridement and antibiotics. This case report highlights the usefulness of MRI in the diagnosis of pyomyositis.

Comparative Study
[Positive Pneumocystis jirovecii PCR in immunocompromised patients with a systemic disease: infection or colonisation?].
Pneumocystis pneumonia is a serious opportunistic infection that frequently occurred in HIV-seropositive patients, prior to the advent of highly active antiretroviral therapy. This infection can also occur in patients with systemic diseases. The diagnostic value of a positive Pneumocystis jirovecii PCR in patients with systemic diseases has not yet been clearly defined. ⋯ A positive P. jirovecii PCR does not always indicate overt infection. However, in a context of severe immunosuppression and in the absence of prophylaxis against Pneumocystis pneumonia, a specific treatment should be considered.

Case Reports
[Acute generalized exanthematic pustulosis induced by hydroxychloroquine: case report].
We report a 45-year-old woman who presented an acute generalized exanthematic pustulosis induced by hydroxychloroquine. Acute generalized exanthematic pustulosis is a severe eruption that is usually drug related. This side effect should be known as new therapeutic challenge would induce more severe clinical features.

Extracolonic manifestations of Clostridium difficile infections have rarely been reported as a reactive arthritis. We report a 43-year-old woman who presented with a polyarthritis following pseudomembranous colitis. ⋯ Corticosteroids were prescribed and clinical manifestations resolved within 3 weeks. Ten months later, there was no relapse and no sequela.
