Obstruction| Other Cancers

Your Path

  • Obstruction| Other Cancers


  • Aside from primary colon cancers, other primary malignancies within the colon that can cause obstruction:
  • Lymphoma (colon is rich in lymphatics)
  • Melanoma - either known w/significant depth of invasion or unknown previously
  • Direct extension from other pelvic tumors (bladder) - which would be unusual
  • Metastatic disease spreading to the colon from elsewhere (rare)


  • If primary lymphoma: fever, chills, weight loss, sweats, lymph nodes identifiable elsewhere
  • Evidence of melanoma elsewhere (notorious for spreading to where it wants)

Physical Exam Findings

  • Might have palpable mass
  • Evidence lymph nodes, melanomatous lesions elsewhere
