High-magnification micrograph showing the characteristic large cells with abundant eosinophilic, i.e. pink, cytoplasm and an eccentrically placed nucleus. H&E stain.<unk>  may exist in the patient’s body for a long time before being diagnosed. It can grow large and push aside surrounding tissues for a long time before causing any discomfort. Therefore,<unk>  symptoms may either be a painless swelling, or a soreness caused by compressed nerves or muscles, affecting the range of motion in the area. Pathology The definitive diagnosis of<unk>  is based on its appearance under the microscope (i.e., its histomorphology), and presence of the characteristic chromosomal translocation (i.e., cytogenetics).<unk> ' histomorphologic features include an<unk> -like pattern at low magnification and the presence of large cells with abundant eosinophilic cytoplasm and eccentric nuclei. Calcifications are commonly present, as may be seen with slow-growing neoplasms.
