Spindle cell sarcoma is a type of cancer which occurs on the connective tissues of the body. The name âspindle cellâ comes from the shape the cells appear to have when viewed through a microscope.
A âspindle-cellâ component (spindle cells are often associated with smooth muscle and connective tissue) is found in up to 40% of pleomorphic breast carcinoma tumors, sometimes accounting for more than 25% of the total tumor mass.leomorphic breast cancer tumors will often fail to show the âclassicâ features of breast carcinoma on mammography, and ultrasound is not necessarily any clearer. Mammograms of pleomorphic breast cancer tumors will tend to show well-circumscribed lesions without evidence of calcification.
