Abstract
Pseudoangiomatous stromal hyperplasia (PASH) is a benign proliferation of the hormonally responsive, specialized mammary stroma characterized by slit-like pseudovascular spaces lined by bland spindle cells. It is usually an incidental microscopic finding but in some cases it may present as a slowly growing mass. A malignant counterpart for this lesion has not been reported. We describe a case of PASH with foci of malignant histologic features presenting as a slowly growing mass in a 30-year-old woman. The previously reported variants of PASH and the other mammary stromal lesions related to PASH are also discussed. This is perhaps the first case of PASH with foci of malignant histologic features reported in the literature and represents a rare sarcoma derived from specialized hormonally responsive mammary stroma.
