Abstract

Marjolin’s ulcer is a rare but aggressive form of skin cancer that often presents significant surgical challenges due to the complex anatomy of the pelvis and the necessity for wide excision to avoid recurrence. This case report highlights the innovative use of a 3-dimensional (3D)–printed model for the precise planning and successful execution of a high partial sacrectomy in a 48-year-old male patient with quadriplegia. This patient, who had sustained a cervical spine injury in 1996, developed a sacral pressure sore that progressed into a Marjolin's ulcer. Utilizing high-resolution 3D computed tomography scans, we created a detailed 3D-printed model of the patient's sacrum, which facilitated a thorough understanding of the tumor's anatomy and its spatial relationships with critical structures. This approach significantly aided the surgical team in executing a challenging excision while minimizing risk to the adjacent organs. This case underscores the potential of 3D printing technology to enhance surgical planning and outcomes in complex oncological resections, particularly in anatomically challenging regions.
