Primary bone lymphoma (PBL) is a rare but distinct clinicopathological disease, usually occurring in the pelvis, spine, and ribs. To date, only a few cases have been reported as beginning in the patella. Due to the lack of clinical evidence, the optimal treatment strategy has not been established. Here, we report a case that presented unexplained right knee pain. The case was diagnosed with the non-germinal center, diffuse large B cell lymphoma in the patella by imaging examinations and bone biopsy. Then, the patient received a patellectomy and eight cycles of R-CHOP chemotherapy. After treatment, the patient achieved a favorable prognosis and satisfactory functional recovery.
原发性骨淋巴瘤（PBL）是一种罕见但独特的临床病理疾病，通常发生于骨盆、脊柱和肋骨。迄今为止，仅有少数病例报告始于髌骨。由于缺乏临床证据，尚未确立最佳治疗策略。在此，我们报告一例出现不明原因右膝疼痛的病例。通过影像学检查和骨活检，该病例被诊断为髌骨非生发中心弥漫性大B细胞淋巴瘤。随后，患者接受了髌骨切除术和8个周期的R-CHOP化疗。治疗后，患者预后良好，功能恢复满意。
