title: CD4 lymphopenia in a patient with cryptococcal osteomyelitis.
abstract: Cryptococcus neoformans is a rarely reported cause of osteomyelitis. In most cases, no obvious underlying condition is found. Immunological laboratory data, however, are not generally available. In the present case of cryptococcal osteomyelitis, idiopathic CD4 lymphopenia was detected. This immunodeficiency is found in cases of disseminated cryptococcosis by chance. Possibly, it may be one so far unrecognized underlying condition in cryptococcal osteomyelitis.
