title: Unusual manifestations of non-Hodgkin's lymphoma.
abstract: Two patients with biopsy proven lymphomatous infiltration of uncommon sites are presented. One had histiocytic lymphoma, involving the true vocal cord with a squamous cell carcinoma on the opposite vocal cord. The other had diffuse well-differentiated lymphocytic lymphoma, presenting with nodal and periorbital disease. After local radiation therapy and while clinically free of other lesions, he developed hemotochezia due to several polypoid lesions throughout the entire colon and prostatic infiltration with symptoms of lower urinary tract obstruction. Both problems were solved after specific treatment.
