Though these lesions are comprised of histologically and immunohistochemically distinctive perivascular epithelioid cells, their diagnosis is controversial and some investigators question their existence entirely. We present a unique case of perhaps the earliest microscopic example of a LAM PEComa in the uterine myometrium, and contrast its features to that of intravascular adenomyosis, intravascular endometrial stromal sarcoma, and intravascular leiomyoma.\nCopyright ©2011International Society of Gynecological Pathologists","source_license":"CC0","license_restricted":false}
