A diagnosis of marginal zone lymphoma following surgical correction of hallux abductovalgus: a case report.

UNLABELLED: Marginal zone lymphoma is a neoplasm affecting the lymphatic system, including the bone marrow, thymus, spleen, and lymph nodes. This type of non-Hodgkin's lymphoma affects B cells and is estimated to comprise between 5% and 17% of all non-Hodgkin's diseases. The incidence of finding any neoplasm within the foot and ankle has been estimated to be only 2.0% to 3.5% of all patients. However, despite the low incidence of cancer found within the foot and ankle, the clinician must be mindful that the possibility does exist and should thus consider surgically excised soft tissue and bone for pathological evaluation. A case report of marginal zone lymphoma, incidentally diagnosed through hallux valgus surgery, is presented.

LEVEL OF CLINICAL EVIDENCE: 4.
