Primary lymphoma of the calcaneus with recurrence in the distal tibia: a case report

Primary lymphoma of bone in general is a very rare condition which represents approximately 3% of all primary malignant bone tumors. Of these, less than 1% originate in the foot. The following case presentation demonstrates a patient who presented with primary lymphoma of the calcaneus, diagnosed by open bone biopsy and treated with radiation therapy. The patient remained disease free for almost 3 years, at which time recurrence to the contralateral distal tibia was diagnosed again through open biopsy.
