Implantation of oral squamous cell carcinoma at the site of a percutaneous endoscopic gastrostomy: a case report.
A 55-year-old man had an operation and radiotherapy for a squamous cell carcinoma of the oral cavity and developed a metastatic deposit at the site of a percutaneous endoscopic gastrostomy, with no other evidence of systemic spread. Treatment of the metastasis was by neo-adjuvant chemotherapy with cisplatin and 5-fluorouracil (5-FU) followed by en bloc resection of the stomal recurrence on the anterior abdominal wall. There has been no evidence of recurrence to date. Only 17 other cases of metastasis to this site from a primary tumour in the upper aerodigestive tract have been reported. We review the relevant publications and discuss the techniques, complications and possible mechanisms of spread and their implications for the use of percutaneous endoscopic gastrostomy in head and neck cancer surgery.
