Obstructive solitary bronchial non-Hodgkin's lymphoma--a rare presentation of primary extranodal disease

Endobronchial involvement by non-Hodgkin's lymphoma (NHL) is uncommon and usually occurs in the presence of more generalised disease. Solitary endobronchial lymphoma in the absence of disease elsewhere is extremely rare. In this report we describe a patient with an obstructing endobronchial mass which was the initial manifestation of NHL. The patient was treated initially with radiotherapy followed by cyclic combination chemotherapy with initial complete resolution of the endobronchial disease. However, he subsequently developed widespread lymphoma. This unusual presentation of NHL is discussed and the relevant literature is reviewed.
