Epithelioid Angiosarcoma Arising from a Huge Leiomyoma: A Case Report and a Literature Review

Figure 6

Microscopic findings of the tumor (H.E. stain; original magnification X40). The tumor was mostly composed of spindle-shaped cells, consistent with degenerated leiomyoma. Enlargement of blood vessels was observed within an area of about 2 cm × several mm, and proliferation of atypical cells showing a fine meshwork microvascular structure was observed in the blood vessel cavity.
