Sumario:Background: Tularemia is a devastating disease that affects multiple organ systems and can have several different presentations. In its most frequent form—that of ulceroglandular tularemia—a detailed history and physical examination can enable a physician to make the diagnosis clinically, leading to the prompt initiation of the appropriate antibiotic treatment. Detailed Case Description: A 63-year-old man was brought by ambulance to the emergency department for an evaluation of an altered mental status noted by his psychiatrist at a telehealth appointment. A physical examination revealed a fever and two ulcerative lesions with a central eschar on his left leg (of which the patient was unaware) with ipsilateral tender inguinal lymphadenopathy. When asked, the patient recalled visiting Martha’s Vineyard and having removed ticks from his legs. Gentamicin was administered on the clinical suspicion of ulceroglandular tularemia. Blood and skin lesion cultures grew Gram-negative rods, which were confirmed to be Francisella tularensis on hospital day eight, and the patient fully recovered. Conclusion: This case highlights the importance of clinician perception of altered mental status as a key alarm sign, the necessity of a thorough physical exam independent of the chief compliant in the emergency department, and the essential role of pattern recognition by front-line providers for the appropriate management of uncommon but serious infections such as tularemia.
