Low-grade fibromyxoid sarcoma arising in the big toe.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare neoplasm commonly affecting young adults and typically arising in the somatic soft tissue of the proximal extremities. Its occurrence within the big toe is exceedingly rare. A 43-year-old man had surgery on a mass located in the big toe, which was first noted 6 months previously. Histological examination revealed LGFMS. One year after surgery, the patient is alive with no evidence of disease. Low-grade fibromyxoid sarcoma is a rare neoplasm that should be considered in the differential diagnosis of spindle cell neoplasms of the foot.
