Abstract
BACKGROUND: There is no universal management protocol concerning invasive malignant tumors of the scalp with bone and dura mater invasion. The aims of this study were to report and discuss our experience in the management of these forms of tumors. METHODS: We retrospectively reviewed all consecutive patients of microsurgical scalp reconstruction performed after resection of invasive cutaneous malignancies of the scalp, calvarium, and dura mater from 2017 to 2019, at Pitié-Salpêtrière University Hospital (Paris, France). RESULTS: Five patients met inclusion criteria. There were three squamous cell carcinomas and two sarcomas. Mean age at surgery was 63.6 years. The sex ratio male/female was 4. Two received radiation prior to resection and two patients had a history of prior scalp tumor surgery. All the patients underwent craniectomy and the mean cranial defect size was 41 cm2. Cranioplasty was performed in one patient. Soft tissue coverage was provided by free tissue transfer of latissimus dorsi muscle in all patients. In four patients, split thickness skin graft was performed in a second surgical stage few weeks later. There were no intraoperative complications and no complications into the donor site for the tissue transfer or the skin graft. Two patients had flap necrosis that healed after a new free flap of latissimus dorsi. CONCLUSIONS: Wide resection with craniectomy and reconstruction with microvascular free tissue transfer provides safe and reliable treatment of recalcitrant invasive scalp skin cancers. The surgical management of these complex patients is a challenge that must be conducted by trained, experienced, and multidisciplinary teams.
