A unique presentation of non-Hodgkin's lymphoma in the foot

Non-Hodgkin's lymphoma of the foot is a relatively uncommon pedal neoplasm. The authors discuss the etiology, incidence, histology, morphology, metastatic rate, and treatment of this entity. Non-Hodgkin's lymphomas rarely present as destructive lesions of bone; when they do, they usually involve the axial skeleton or proximal long bones. Additionally, the authors present a clinical case reporting findings of Non-Hodgkin's lymphoma after surgical correction of a hammertoe deformity and subungual exostosis. The pathologic microscopic evaluation of the resected bone assisted in diagnosis of this condition.
