Answer

Fine needle aspiration may have an ancillary role in diagnosis. On such aspiration, a large amount of clear gelatinous fluid is expressed. Rare macrophages and histiocytes are found in the thick, mucoid matrix, as are a few tight clusters of cells, some collagen fibers, and red blood cells with altered shapes. [8]
