Although waning in incidence diphtheria can cause severe disease as in this rare Swedish case with several complications.Case presentationA 55-year old male presented to the emergency room with severe respiratory symptoms and greyish membranes in the airways, which turned positive for C. diphtheriae. He was put on ventilator support and remained hospitalized for three months. During care he developed myocarditis and severe neurological disease and he was also co-infected with tuberculosis. The patient was discharged with a favorable outcome.ConclusionsDiphtheria should be suspected in patients with life-threatening pneumonia especially if the patient has a history of travelling. Our patient was not treated with diphtheria anti-toxin (DAT) which may have contributed to the severity of the disease.
