title: Low-grade fibromyxoid sarcoma: a brief review.
abstract: Low-grade fibromyxoid sarcomas are uncommon deep soft tissue neoplasms first described by Evans in 1987. They exhibit a deceptively benign appearance, with a whorled or linear arrangement of spindle-shaped cells showing few to absent mitoses. A characteristic, but not specific, feature is the presence of areas of myxoid stroma. Recurrences are common, and late metastases have been recorded. A closely related but morphologically distinct tumor, the so-called hyalinizing spindle cell tumor with giant rosettes, has also been described; both neoplasms share the same cytogenetic abnormality, a balanced translocation resulting in a FUS/CREB3L2 fusion gene. Because of similar clinical behavior and the common cytogenetic abnormality, some authors prefer to consider both lesions as a single entity within the spectrum of low-grade sarcomas.
