In our case, tumor tissues were collected thrice during the course of treatment for immunohistological evaluation. The tumor was consistently positive for VEGF, suggesting that pazopanib was effective in the treatment of solitary fibrous tumor.
This is the first report using an anti-tumor drug called Pazopanib for a
case of solitary fibrous tumor that occurred in the ear canal. Pazopanib
will be useful for clinicians involved in this case in the future, we
have reported the detailed progress and immunological analysis.
