Low-grade fibromyxoid sarcoma is a slowly growing soft tissue neoplasm, mostly affecting young individuals. It usually arises in a deep soft tissue of the lower limbs and trunk, but few cases of low-grade fibromyxoid sarcoma that presents sciatic nerve pain have been reported. We report a 34-year-old woman with a low-grade fibromyxoid sarcoma originating in the left gluteal region that initially presented as sciatic nerve pain; she had experienced this type of pain for 5 years before visiting our hospital. Magnetic resonance imaging revealed a tumor in the left gluteal region. After needle biopsy revealed it to be a low-grade fibromyxoid sarcoma, we performed the wide resection. Intra-operative findings revealed no tumor invasion into the sciatic nerve. No recurrence or metastasis has been detected 6 months post-surgery. Oncologists who encounter patients with sciatic nerve pain should consider the possibility of less common causes such as the low-grade fibromyxoid sarcoma found in our patient.
