Fifteen cases of primary pulmonary Hodgkin's disease are reported. This presentation of Hodgkin's disease occurred more frequently in women (2:1) and older individuals, and B symptoms were relatively common (7 of 13). The majority of patients had nodular lesions on chest radiographs. An unfavorable prognosis was linked to B symptoms, older age (greater than 60 years) and multiplicity and bilaterality of lung lesions. The histologic differential diagnosis is discussed, particularly in regard to Wegener's granulomatosis and non-Hodgkin's lymphomas.
