Overview
Two cases of low-grade fibromyxoid sarcoma are presented. In a 31-year-old male the tumour arouse in the scapular soft tissues and local recurrence occurred. In a female of 45, the neoplasm was located in the thigh. Histologically, the neoplasms with low cellularity of deceptively benign- appearing small fibroblastic spindle cells demonstrated alternating dense fibrous and loose myxo- id areas, showing a mainly whorled and swirling growth pattern. In myxoid areas a prominent vascular component was present. Mitoses and cellular atypia were absent. Tumor cells showed staining with anti-vimentin and occasionally anti-actin antibodies. As a distinctive soft-tissue sarcoma, low-grade fibromyxoid sarcoma had to be distinguished from variety of benign and malignant soft tissue tumours such as neurofibroma, liposarcoma, myxoid MFH and others.
