Abstract: We describe a case of meningococcal gluteal injection abscess in a 3-year-old boy with acute lymphocytic leukemia. Pus from the abscess as well as blood grew Neisseria meningitidis. The patient did not show any other symptoms or signs of meningococcal sepsis or meningitis. A lumbar puncture was normal and did not reveal any meningococci in the cerebrospinal fluid. Patient was discharged uneventfully on antibiotics after surgical drainage.
