To date, only around 300 cases of metastasis to the penis have been reported and the primary cancer has been generally found in genitourinary structures. However, exceptional cases in which the primary site has been situated in organs like esophagus, pancreas, stomach have been published. We report an uncommon case in which the primary tumor was located in the cecum. To our knowledge, this is the first case of penile metastasis in which the responsible tumor was located in the cecum and in which the mode of metastasis was not direct invasion. As the tumor was restricted to the colon wall without invasion to neighbouring structures, and because colon cancer follows mainly the lymph-vascular route to its dissemination, this route is the most likely mode of the spread. By magnetic resonance imaging (MRI) on penile shaft, multiple nodules were clearly visualized. Nevertheless, as in most cases, in spite of the availability of advanced and precise diagnostic methods, the information was of little value for the patient. His survival was short.
迄今为止，仅报告了约300例阴茎转移癌病例，原发癌通常发现于泌尿生殖结构。然而，也有一些特殊病例报道，其原发部位位于食管、胰腺、胃等器官。我们报告一例罕见病例，其原发肿瘤位于盲肠。据我们所知，这是首例原发肿瘤位于盲肠且转移方式并非直接侵犯的阴茎转移癌病例。由于肿瘤局限于结肠壁，未侵犯邻近结构，且结肠癌主要通过淋巴血管途径扩散，因此这是最可能的转移方式。通过阴茎轴的磁共振成像（MRI），清晰可见多个结节。然而，与大多数病例一样，尽管有先进精确的诊断方法，这些信息对患者价值不大。他的生存期很短。
