Metastatic spread from squamous cell carcinoma over implantable port

Here, we report the first case of a patient with hypopharyngeal tumor who developed chest wall metastasis over the totally implantable venous access port inserted in the internal jugular vein” Mangla et al (2017).

Abstract:

BACKGROUND: The totally implantable venous access port plays a crucial role in delivering chemotherapy in the outpatient setting. Here, we report the first case of a patient with hypopharyngeal tumor who developed chest wall metastasis over the totally implantable venous access port inserted in the internal jugular vein.

METHODS: Our patient, a 58-year-old man with a hypopharyngeal tumor presented with a lump over the totally implantable venous access port site. The port was removed and the lump was biopsied. The CT studies showed that the tumor had spread along the catheter from the hypopharynx to the chest wall.

RESULTS: The pathology from the biopsy showed squamous cell carcinoma (SCC). The patient had poor performance status and opted for hospice care.

CONCLUSION: 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.
