Large B-cell lymphoma mimicking iliopsoas abscess following open revision of proximal femur infected non-union: a case report

Abstract

BackgroundExtranodal presentation of lymphoma is a rare occurrence. It has been postulated that chronic antigen stimulation may predispose a patient to the development of lymphoma.Case presentationWe present a case report of a large extranodal B-cell lymphoma mimicking a postoperative abscess following surgery for an infected proximal femur nonunion in an 80-year-old Caucasian male of Italian descent.ConclusionsThis case highlights the need to consider malignancy in revision surgery, careful examination of operative specimens and the need for further understanding of the role of metal implants in chronic antigen stimulation.

Diffuse large B-cell lymphoma mimicking chronic osteomyelitis of the ankle joint: A case report

“…4 These clinical presentation and prognostic parameters are identical in both young and elderly patients. 10…”

“…4 These clinical presentation and prognostic parameters are identical in both young and elderly patients. 10 Primary bone lymphoma patients whose primary tumor sites were appendicular and craniofacial at presentation had a significant survival advantage over those with axial involvement. 11 DLBCL involving bones as the only site of disease has a favorable prognosis as compared to those with a secondary bone involvement or bone marrow dissemination.…”

“…20 In the literature, a broad range of presentations involving the musculoskeletal system, such as chronic leg ulcer, 21 long-standing chronic suppuration 22 and pain in the subtalar and talonavicular joints without bony involvement on the top of rheumatoid arthritis, 23 are reported. McCammon et al 10 reported a large B-cell lymphoma mimicking iliopsoas abscess following the open revision of an infected non-union proximal femur. A 27-year-old female with DLBCL of the right distal femur, recognized after a three-year history of chronic osteomyelitis, was documented by Alfredo et al 24 However, it is difficult to make a conclusive diagnosis of musculoskeletal lymphoma using imaging criteria alone.…”
