Although bone tumors are often located in the knee area, primary tumors of the patella are rare, and patellar metastases extremely rare. Only a few cases were reported in the literature originating from different primary tumors, mostly lung and breast [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 19, 20, 22]. There is only one other case description of a colon carcinoma [21]. We present a rare case of primary sigma carcinoma and patellar metastasis. Because of the increasing rate of colon carcinomas, neoplastic disease must be considered in the differential diagnosis in any patient with otherwise unexplained knee pain.
尽管骨肿瘤常位于膝关节区域，但髌骨原发性肿瘤罕见，而髌骨转移瘤极为罕见。文献中仅报道了少数源自不同原发性肿瘤的病例，主要是肺癌和乳腺癌[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 19, 20, 22]。仅有另一例结肠癌的病例描述[21]。我们报告一例原发性乙状结肠癌伴髌骨转移的罕见病例。由于结肠癌发病率不断上升，对于任何有不明原因膝关节疼痛的患者，在鉴别诊断中都必须考虑肿瘤性疾病。
