Septic arthritis of hip in a neutropenic child caused by Salmonella typhi.

A 5-year-old male child was undergoing chemotherapy for pre-B acute lymphoblastic leukemia. He developed Salmonella typhi arthritis of his left hip joint during neutropenic phase. Infection was successfully treated with intravenous antibiotics without surgical management. S. typhi is a potential cause of arthritis, especially in immunocompromised children. More than 100 other cases of Salmonella arthritis are reviewed and reveal a disease primarily of children and young adults with a favorable treatment response.
