title: Pulmonary hyalinizing granuloma presenting as multiple cavitary calcified nodules.
abstract: We describe a patient with PHG who presented with multiple cavitary calcified nodules. Laboratory evaluations revealed that she had serum immune abnormalities, and a histoplasmin skin test yielded positive results. Her Histoplasma infection may have produced a hyperimmune reaction that resulted in PHG and the calcified nodules.
