case_images: The mass was well confined, smooth, elastic-firm, not adherent to the overlying skin and was held in place by the basement structures (fig. 1).
case_images: a MRI shows a circumscribed mass measuring 20 x 8 mm, between the right inferior scapular angle and the rib. The signal of the lesion demonstrated almost heterogeneous isointensity to the muscles on T1-weighted images. b Part of the mass shows high intensity on T2-weighted images.

case_images: The signal of the lesion demonstrated almost heterogeneous isointensity to the muscles on T1-weighted images (fig. 2a), while part of the mass showed high intensity on T2-weighted images (fig. 2b).
case_images: A well-demarcated yellowish tumor can be seen.

case_images: A well-demarcated tumor was found that looked like it had arisen from the right inferior scapular angle (fig. 3).
case_images: a Low magnification of an H&E-stained specimen shows a well-encapsulated tumor. H&E. x1. b The tumor contained histiocytes with abundant eosinophilic cytoplasm, fibroblasts with fusiform-shaped nuclei and collagen hyperplasia. H&E. x20. c Many multinucleated osteoclast-like giant cells can be seen in the tumor. H&E. x40. d The proliferation of foam cells can be observed in the tumor. H&E. x40.

case_images: The histological examination revealed a well-encapsulated tumor (fig. 4a), which contained histiocytes with abundant eosinophilic cytoplasm, fibroblasts with fusiform-shaped nuclei, collagen hyperplasia (fig. 4b), multinucleated osteoclast-like giant cells (fig. 4c) and foam cells (fig. 4d).
