Synopsisi
hypocellular, hypovascular regions
cytologically bland stellate and bipolar fibroblasts separated by abundant extracellular myxoid matrix
areas of increased cellularity and vascularity that can lead to a mistaken diagnosis of sarcoma
Differential diagnosis
myxofibrosarcoma
low-grade fibromyxoid sarcoma
myxoid liposarcoma
Prognosis
Surgical excision is virtually always curative. Recurrence, even after incomplete resection, is exceptional.
