Metastatic spread from squamous cell carcinoma of the hypopharynx to the totally implantable venous access port insertion site: Case report and review of literature

Abstract

We present a novel case of metastasis over the totally implantable venous access port implanted in a patient with a hypopharyngeal tumor. We also reviewed relevant literature comparing the data from percutaneous endoscopic gastrostomy (PEG) tube site metastasis with our patient and other similar case reports.

A Retrospective Study of the Use of Antibiotic Lock Therapy and Cluster Nursing Management in Infections in Children with Short Bowel Syndrome or Solid Abdominal Tumours Treated with Totally Implantable Venous Access Ports

“…Mangla et al reported on the first patient with squamous cell carcinoma of the hypopharynx who developed tumour seeding not only at the insertion site of the TIVAP but also along the tunnel tract of the catheter itself. 19 Of the 200 children selected for this study that were implanted with TIVAPs in our department, eight were diagnosed with CRBSIs, and the infection rate was 3%, which is consistent with the findings from the Infectious Diseases Society of America mentioned above ( Table 3 ).…”

Subcutaneous metastasis at the totally implantable venous access port site in a patient with pancreatic cancer

“…There are only a few reports of cancer metastasis around TIVAP insertion sites (Table 1). [1][2][3] The literature indicates that head-andneck, hematologic and intrathoracic malignancies appear to be the most common cause, with squamous cell carcinoma being the most common histologic type. Aggressive, progressive or poorly differentiated tumours are more likely to be associated with tumour dissemination to the insertion site than localised or welldifferentiated tumours.…”
