Umbilical metastasis, also called Sister Mary Joseph's nodule (SMJN), is defined as the umbilical nodule associated with advanced metastatic intra-abdominal and pelvic malignancies. A patient with umbilical metastasis has been deemed to have a poor prognosis. Rectal cancer presenting with a SMJN is a rare phenomenon, especially in the early stage and in middle-low rectal cancer.
We report a case of a 70-year-old male presenting with umbilical metastasis derived from rectal cancer (10 cm from the anal verge, T2N0).
For rectal cancer with umbilical metastasis, the exact metastatic routes as well as the criterion of diagnosis and treatments are not very clear. Here we review the literature on rectal cancer and SMJN to deepen the understanding of this disease.
脐部转移，也称为玛丽·约瑟夫修女结节（SMJN），定义为与晚期腹腔和盆腔转移性恶性肿瘤相关的脐部结节。脐部转移患者的预后被认为较差。出现SMJN的直肠癌是一种罕见现象，尤其是在早期以及中低位直肠癌中。
我们报告一例70岁男性患者，其脐部转移源自直肠癌（距肛缘10 cm，T2N0）。
对于伴有脐部转移的直肠癌，确切的转移途径以及诊断和治疗标准尚不完全明确。在此，我们回顾有关直肠癌和SMJN的文献，以加深对该疾病的认识。
