Case report: Lymphoma masquerading as infection

During surgical training, medical students and residents constantly are reminded to culture every suspected tumor and send tissue for pathologic evaluation for every suspected abscess. A diagnosis of cancer can be missed easily if this procedure is not followed, delaying the diagnosis and possibly adversely affecting the patient's prognosis. The confusion also may be compounded by a sterile abscess, positive culture results or a negative biopsy specimen. Therefore it is imperative to do a biopsy and a culture on any suspect lesion. An additional workup and possible biopsy may be warranted for a nonhealing wound that has been treated appropriately. The cases of three patients with lymphoma that were treated as infectious processes are presented. In all three instances, the appropriate treatment was delayed because of a delay in diagnosis.
