title: [Granular cell tumor of the breast--review of the literature and research for a period of 5 years].
abstract: Granular cell tumor is relatively rare neoplasm, and always benign in its prognostic behavior. Location of this tumor in the breast presents serious problems for differential diagnosis, both from a clinical point of view and at gross pathologic examination, because of its resemblance to carcinoma. The histogenesis of these lesions has been widely debated in the past, but no universally accepted conclusions has been reached. Most granular cell tumors appear to be derived from Schwann cells of peripheral nerves, but many different lesions in the breast show granular cell changes. The authors describe four typical cases of breast granular cell tumors that occurred in patients of different ages, and discuss the most important problems concerning this lesion.
