<unk>  can be seen in a urine sample through Papanicolaou staining or phase-contrast microscopy. By Papanicolaou stain, most<unk>  have an enlarged nucleus that bears a basophilic inclusion which is surrounded by chromatin that confers a ground-glass or gelatinous appearance. Sometimes the nuclear inclusion has a vesicular aspect, the chromatin may be clumped, and it may be surrounded by a halo. When<unk>  derive from the urothelium, the heavily enlarged and altered nuclei as well as the irregular shape of the<unk> body can mimic the changes observed in neoplastic<unk> . By phase-contrast microscopy,<unk>  show the same abnormalities described for stained specimens, namely, enlargement of the nucleus with a ground-glass or vesicular appearance, altered chromatin, enlarged nucleoli, the presence of a halo, and at times also cytoplasmic vacuoles. In our experience, these features make<unk>  different from tubular<unk>  and transitional<unk>  found in all other conditions. The only exception is represented by<unk>  infected by cytomegalovirus, which frequently show a ‘bird's eye’ appearance. As such,<unk>  may strongly resemble malign cancer<unk> , from which they also derive their name. This is because they can be mistaken for cancer<unk> , or the other way around where cancer<unk>  can be mistaken for<unk> .
