Fascitis necrosante como primera manifestación de tuberculosis en un paciente inmunodeprimido

Disseminated tuberculosis is a process that mainly affects immunocompromised hosts. Its initial appearance as necrotising fasciitis is exceptional especially if it is not associated to a bone disorder. The diagnosis of this rare complication requires a high degree of suspicion and the evidence of Mycobacterium tuberculosis in the muscular tissue, since the symptoms may mimic the underlying illness itself, for this reason the most sensitive method for demonstrating tuberculous infection is a muscular biopsy. Here we present the case of a patient who was receiving immunosuppressant therapy for nephrotic syndrome by minimal lesion glomerulonephritis and who developed this rare complication, where diagnosis was made by muscular biopsy. So we do a review of similar case reports in the literature.
