title: [Difficulties in the diagnosis of primary malignant histiocytoma of the lung].
abstract: A case is presented of a round coin shadow seen on a routine chest radiogram producing grave diagnostic problems. During hospitalization the patient presented neurological and bone and joint involvement symptoms. Transthoracic needle biopsy of the lesion allowed to diagnose large cell cancer, but autopsy changed this diagnosis to malignant histiocytoma.
