Spindle cells

Cathy Harvey Of all the masses that occur in the skin and subcutis, probably the most care needs to be taken when evaluating spindle cells from mass lesions, as reactive spindle cells associated with fibroplasia cannot be easily distinguished from neoplastic cells on cytology. Often these lesions are firm and do not exfoliate well, making […]
