introducing a case of brucellosis with severe septicemia and pancytopenia

introduction: the most common symptom of brucellosis is osteoarticular manifestation. urogenital manifestation, hepatitis, cns and respiratory system involvement and endocarditis are also reported. mild leukopenia with lymphocytosis, anemia, thrombocytopenia and seldom pancytopenia is seen. case presentation: a 22-year-old man with fever and chills, abdominal pain and diarrhea came to the hospital. he had headache, malaise, anorexia and dry cough, for 2 weeks. he had no exposure to domestic animals and hadn’t consummed any unpasteurized dairy. in lab data, he had leukopenia, relative lymphocytosis, anemia and thrombocytosis, wright = 1/2560, 2me = 1/1280, alt=193, ast= 446, alkp = 375. conclusion: as long as the patient hadn’t have any exposure to domestic animals and also hadn’t consummed any unpasteurized dairy, the serology (2me = 1/80, wright= 1/40) from outside the hospital was repeated and noted results was detected. in endemic areas, in septicemia and pancytopenia or bycytopenia setting we should consider brucellosis in differential diagnosis.
