Extract
Non-Hodgkin's lymphoma can present as either a nodal form with local or
regional lymphadenopathy or, less commonly, as an extranodal form outside the
lymphatic
system1,2.
Musculoskeletal involvement of non-Hodgkin's lymphoma occurs in 25% of
patients, typically as metastasis and, rarely, as primary lymphoma of bone or
soft
tissue3,4.
Non-Hodgkin's lymphoma involving the synovium is rare, with only thirteen
reported
cases4-15.
Additionally, all of these reported patients presented with some symptoms
suggestive of inflammatory arthropathy, including pain, intra-articular
effusion with joint swelling, or radiographic changes (see Appendix). None of
the previous reports described lymphoma involving the elbow joint.
