Hodgkin lymphoma presenting with exclusive or preponderant pulmonary involvement: a clinicopathologic study of 5 new cases.
A review of the pathological features of Hodgkin lymphoma manifesting with exclusive or preponderant lung involvement is given for 5 patients. Three patients were men and 2 were women, with an age range 17 to 48 years (median, 42 years). They presented with nonspecific symptoms including dry cough, fever, or chest pain. Initial clinical assessment suggested a lung tumor. Pathological evaluation was carried out on lung biopsy, wedge resection, lobectomy, or pneumonectomy specimens. All the cases showed diagnostic Reed Sternberg cells within the proper background. Immunopositivity for CD15 and CD30 was documented as well. Nodular sclerosing and mixed cellularity were the documented subtypes. Additional histologic features were a pronounced nodular growth pattern with or without necrosis, a diffuse hypersensitivity pneumonia-like picture, or acute pneumonia-like changes. Our study confirms that the recognition of Hodgkin lymphoma in lung, although based on well-established morphologic criteria, may represent a source of interpretative problems because of the unusual clinical presentation as well as the peculiar histologic changes induced within the pulmonary microenvironment.
