Abstract

Low-grade fibromyxoid sarcoma (previously known as Evans tumor) is a rare soft tissue neoplasm characterized by a deceptively bland appearance despite the potential for late metastasis or recurrence. We describe a 13-year-old patient with a popliteal fossa mass initially thought to be benign that, because of array-comparative genomic hybridization findings and subsequent immunohistochemistry, was diagnosed as low-grade fibromyxoid sarcoma. The array-comparative genomic hybridization demonstrated a loss of 11p11.2p15.5 and a gain of 16p11.2p13.3 with breakpoints involving the CREB3L1 (cAMP responsive element-binding protein 3-like 1) and FUS (fused in sarcoma) genes, respectively. Subsequent fluorescence in situ hybridization analysis of a dual-labeled break-apart FUS probe on interphase cells was positive. Our case highlights the importance of using genetic information obtained via array-comparative genomic hybridization to classify accurately pediatric soft tissue tumors.
