Abstract
Objective: To report a case of schwannoma in a filling pit with resection of the pelvic component by robotic approach. Case details: A 57-year-old female patient was admitted to the emergency unit of the hospital with pain in the right hip region for 12 days, progressing with fever and worsening of the pain. Imaging exams showed a tumor that occluded the right obturator fossa and extended via obturator foramen to the right intergluteal compartment. Opted for a combined robotic approach for pelvic and posterior conventional access to the gluteal compartment. In the surgical procedure, robotic access to the pelvis enabled decreased damage to the pelvic nerves and low volume of blood loss. The anatomopathological study showed a neoplasm formed by the proliferation of spindle cells, arranged in multidirectional bundles, with the formation of Verocay bodies and histiocytoid cells, requiring immunohistochemical analysis for better diagnostic clarification. This, in turn, revealed diffuse expression for protein S-100, confirming the schwannoma hypothesis. Final Considerations: In this way, robotic surgery tends to grow more and more as an alternative to approach pelvic tumors that are difficult to access, aiming to achieve a better postoperative recovery and increase the patient's quality of life.
