mammary fusiform cell tumors
spindle cell lesions of the breast, mammary spindle cell tumors
Spindle cell lesions of the breast constitute a wide spectrum of benign and malignant proliferations. Myofibroblasts, normal cellular constituents of the mammary intra- and interlobular stroma, compose many of these lesions, which include reactive proliferations and benign or locally aggressive neoplasms.
Types (exemples)
pseudoangiomatous stromal hyperplasia
reactive spindle cell nodule
nodular fasciitis
myofibroblastoma
primary mammary fibromatosis
low-grade metaplastic spindle cell carcinoma
