PET-CT-based resection guide for treatment of auricular squamous cell carcinoma: an innovative clinical management of soft tissue tumors: a case report

To describe the successful use of a PET-CT-based resection guide for the treatment of auricular squamous cell carcinoma. A 69-year-old male presented with a painless growing mass in his left ear helix that had been unsuccessfully treated conservatively by another surgeon. An incisional biopsy revealed moderately differentiated squamous cell carcinoma, and the patient was referred to the department for further management. A PET/CT was performed, which showed uptake of FDG in the ear with a SUV max value and T3N0M0 status. The treatment plan was based on a multidisciplinary team discussion and a thorough evaluation of the PET/CT imaging findings. A decision was made to proceed with excision of the mass with a wide safety margin, using a PET/CT-based resection guide for ear resection. Additionally, partial temporal bone resection, selective neck dissection, and superficial parotidectomy were planned. The patient opted for reconstruction with a scalp rotational flap. The patient’s treatment plan was successful, and at follow-up visits, he remained disease-free. This case report highlights the importance of using a PET-CT-based resection guide for the treatment of soft tissue tumors, specifically auricular squamous cell carcinoma. It also demonstrates the importance of a multidisciplinary team approach and thorough evaluation of imaging findings in determining an effective treatment plan for patients. The use of PET-CT-based resection guide can be an effective tool in the treatment of auricular squamous cell carcinoma. It can provide more precise and accurate information about the extent of the tumor, leading to a more effective treatment plan. Multidisciplinary team approach and thorough evaluation of imaging findings are crucial in determining the best course of treatment for patients.
