Fatal Lyme carditis in a 37-year-old man shows need for awareness of unusual symptoms

Physicians and the public should be aware of the different presentations of Lyme disease, as people spend more time outside in the warmer weather and as areas in Canada where the black legged tick is found expand. Three articles in CMAJ (Canadian Medical Association Journal), which describe a fatal case in a 37-year-old man, atypical skin lesions in a 56-year-old woman and severe neurological symptoms in a 4-year-old boy, illustrate the diversity in presentations.
