Under the mistaken assumption that these tumors originated from smooth muscle cells, they designated them as leiomyoblastoma, leiomyoma, and leiomyosarcoma, based on their morphologic appearance.
Epithelioid smooth muscle tumors including leiomyoblastoma and clear-cell leiomyoma.
This finding should not be surprising, given the many cytologic variants that are known to occur among uterine leiomyomas, such as epithelioid leiomyoma, stromomyoma, leiomyoblastoma, clear cell leiomyoma, bizarre leiomyoma, and plexiform leiomyoma.
In the past, these tumors were diagnosed as leiomyoma, leiomyosarcoma or leiomyoblastoma.

Traditionally, these tumors have been called leiomyomas, cellular leiomyomas, or leiomyosarcomas, depending on the degree of cellularity, mitotic activity, and evidence of dissemination, or leiomyoblastomas, when showing epithelioid morphology.
