[Polymyositis associated with HIV immunodeficiency: clinical case and literature review].

A 33 year old female, suffering from HIV infection, presents with diffuse myalgia, generalized muscle weakness and painless dysphagia. An extensive work-up allows to diagnose an HIV-related polymyositis; while well-known, this entity is however rarely observed. Technetium-99m MDP skeletal scintigraphy shows multiple extra-osseous accumulations of the tracer: these observations, as well as the differential diagnoses of muscular involvement during HIV infection, are discussed.
