The majority of skeletal lesions affecting the patella are benign and include entities such as chondroblastoma, giant cell tumor, osteomyelitis, and gout. Malignant processes involving the patella are distinctly unusual. Isolated occurrences of plasmacytoma, osteosarcoma, hemangiosarcoma, and metastatic disease have been reported. Malignant lymphoma involving the patella is extremely uncommon, although lymphomatous infiltration of the skeletal system is not a rare event, especially with the histiocytic lymphoma. The most frequent radiologic manifestations of skeletal lymphoma include osteolytic lesions with ill-defined margins involving the metaphysis of the long bones of the lower extremities. Involvement of the short tubular and flat bones, as well as the axial skeleton, occurs less commonly. The prognosis for lymphoma involving the skeleton is poor.
影响髌骨的大多数骨骼病变是良性的，包括成软骨细胞瘤、巨细胞瘤、骨髓炎和痛风等。累及髌骨的恶性病变非常少见。已有孤立性浆细胞瘤、骨肉瘤、血管肉瘤和转移性疾病的报道。累及髌骨的恶性淋巴瘤极为罕见，尽管骨骼系统的淋巴瘤浸润并非罕见事件，尤其是组织细胞淋巴瘤。骨骼淋巴瘤最常见的放射学表现包括边界不清的溶骨性病变，累及下肢长骨的干骺端。短管状骨、扁骨以及中轴骨骼受累较少见。累及骨骼的淋巴瘤预后较差。
