Lymphoma is the seventh most common type of malignancy in both males and females. It may develop in any location where lymphomatous tissue exists. Although extranodal presentation in the lower limb and pelvis are uncommon, it could present with diverse manifestations. We report an unusual case of primary extranodal large B-cell lymphoma of the ankle joint initially presumed to be a chronic osteomyelitis. This case report discusses the impact of imaging studies on decision-making and highlights the need to consider malignancy in chronic infections.

淋巴瘤是男性和女性中第七大最常见的恶性肿瘤类型。它可发生于存在淋巴瘤组织的任何部位。虽然下肢和骨盆的结外表现并不常见，但可能有多种表现形式。我们报告一例罕见的踝关节原发性结外大B细胞淋巴瘤病例，最初被误诊为慢性骨髓炎。本病例报告讨论了影像学检查对决策的影响，并强调在慢性感染中需要考虑恶性肿瘤的可能性。
