Abstract
Brucellosis is the most prevalent bacterial zoonosis worldwide. The WHO estimates that the infection is responsible for more than 500 000 cases per year across the world [1]. Hematological complications like mild anemia and leukopenia have been frequently associated with acute brucellosis, but pancytopenia and thrombocytopenia are less frequently encountered [2]. We are reporting the case of a 73 year old male patient, with pancytopenia that revealed acute brucellosis. Following 6 weeks of antibiotic therapy, our patient showed favorable clinical outcome, and the complete blood count returned to normal. Acute brucellosis should be highly suspected in patients with pancytopenia.
