Identifies a deceptively benign-appearing fibromyxoid sarcoma that has metastasizing potential, suggesting the designation 'low-grade fibromyxoid sarcoma'.
Two deceptively benign-appearing, unclassifiable but very similar fibromyxoid sarcomas characterized histologically by bland, innocuous-appearing fibroblastic cells and a swirling, whorled growth pattern are presented. The tumors both occurred in women in their late twenties and were located in the soft tissues of the scapular area and the axillary-chest wall area, respectively. Lung metastases developed in both cases; one patient died 94 months after excision of the primary neoplasm, whereas the other was alive at 82 months. The designation "low-grade fibromyxoid sarcoma" is suggested for these tumors.
