title: Carcinoma of the larynx, metastatic to illeum, presents as ruptured appendicitis: case report and literature review.
abstract: OBJECTIVE
  Metastasis of laryngeal squamous cell carcinoma (SCC) to the intra-abdominal gastrointestinal tract is exceedingly rare. The objectives of this case report are to describe a case involving a perforated metastasis of a laryngeal SCC to the ileum and to review the literature pertaining to other similar cases.
  
  
  METHODS
  A review of patient's chart and a review of the English literature involving malignant SCC of the larynx with metastasis to the small bowel.
  
  
  RESULTS
  We describe the case of a 58-year-old man who had failed induction chemotherapy and underwent a laryngopharyngectomy with bilateral neck dissection and pectoralis major flap for a T4N2c laryngeal SCC. Subsequently, the patient was treated with postoperative radiation and cituximab.The patient went on to present with symptoms consistent with a ruptured appendix, supported by ultrasound imaging. The patient was taken to the operating room where a right hemicolectomy was performed. Pathological gross examination confirmed a 4 cm transmural perforation in the terminal ileum. Microscopy demonstrated deposits of metastatic squamous cell carcinoma in the surrounding smooth muscle. Metastatic carcinoma was also found in a separate nodule from the abdominal wall. The patient had an uncomplicated post-operative period, and survived several months thereafter.
  
  
  CONCLUSIONS
  Metastasis of laryngeal SCC to the small bowel with perforation is exceedingly rare, but possible. These patients may be successfully managed with resection.
