Cytopathology of Myxoid Soft Tissue Lesions
Myxoid soft tissue lesions are a group of lesions that are distinguished by their unique and consistent ability to produce an overwhelming abundance of myxoid ground substance along with the proliferating cells that constitute the lesion. The myxoid material is composed of sulfated and nonsulfated glycosaminoglycans. It appears on H&E sections as a thin amorphous semitransparent or grey substance. Special stains such as alcian blue can confirm its presence and only sulfated glycosaminoglycans (chondroid substance) will be positive after treatment by hyaluronidase.
