Abstract: Background: Metastatic basal cell carcinomas (BCC) are rare. In event of metastasis, BCCs are most likely to spread to the lymph nodes, lungs, bones, and skin. BCC spreading along implanted devices has not been previously documented. Case presentation: We report a case of a 48-year old man with a head and neck cutaneous BCC involving a cranio-peritoneal shunt, which holds the potential risk of tumor dissemination through this low-resistance pathway. He was followed up over his lifetime to determine if he developed cranial or peritoneal dissemination. Management and outcomes: A multi-disciplinary team approach was undertaken, a joint case between plastic surgery and neurosurgery was required to secure the shunt and complete a wide local excision. Post-operatively, the patient had adjuvant radiotherapy. The metastatic spread in this case followed the usual pattern of BCC metastasis. The patient developed lung nodules and bone metastases, and died 23 months post-operatively. He did not develop cranial or peritoneal metastases. In this case, the involvement of the shunt did not alter the expected pattern of metastatic spread of BCC. Conclusion: There is a limited number of case studies that describe implantable devices as a conduit for tumour dissemination.The risk of dissemination did not occur in this case. The long-term follow-up of this case contributes to the literature on decision making in the management of head and neck tumors involving shunts.
