Hyalinizing spindle cell tumor with giant rosettes of the hand. A surgical and histopathological rarity.

Hyalinizing spindle cell tumor with giant rosettes is a recently described biphasic neoplasm of soft tissue that shares mesenchymal and neuroendocrine features. The tumors have quite distinctive histopathological features with the presence of hyalinized paucicellular foci that are defined as rosettes. Only a few cases of this rare tumor have been described so far. We present an additional case of hyalinizying spindle cell tumor with giant rosettes in a 51 year old female patient who was succesfully treated after radical surgical resection.
