Pseudoangiomatous stromal hyperplasia (PASH) is a benign but rare mesenchymal proliferation of the mammary stroma, characterized by pseudovascular spaces within a hyperplastic matrix. PASH can be classified as either non-tumor-forming or tumor-forming. The non-tumor-forming type is an infiltrative and clinically undetectable mass, incidentally found in approximately a quarter of breast biopsies.

Mesenchymal and spindle cell tumors of the breast represent a broad and heterogeneous group of lesions that may be sampled on core needle biopsy or surgical excision. Mesenchymal lesions unique to the breast are those that derive from the specialized breast myofibroblast, such as mammary myofibroblastoma and pseudoangiomatous stromal hyperplasia. However, any mesenchymal lesion arising in extramammary soft tissue may also arise in the breast, including fibroblastic, peripheral nerve sheath, adipocytic, and vascular lesions.
