Giant soft tissue amyloidoma of lumbar region: A case report and literature review

Localized amyloidoma is characterized by a tumour mass with amyloid deposit in a patient who has no detectable abnormal serum proteins or plasma cell dysfunction. In patients with no history of cancer or dialysis, soft tissue localized amyloidoma is a very rare benign condition and can achieve considerable dimensions. We report a soft tissue localized amyloidoma of the lumbar region in an otherwise healthy patient, the largest of its kind found in literature, and further review those cases previously published of this specific condition. We discuss our literature review, concerning the aetiology and diagnosis of this kind of amyloidoma. Level of Evidence: Level V, diagnostic study
