Cystic solitary fibrous tumor of the liver: a case report.

Solitary fibrous tumors are unusual neoplasms that are rarely found in the liver parenchyma. They are usually described as hard, grayish white, well-defined lesions. Predominant cystic change in a solitary fibrous tumor is an unexpected finding, with only a few previous cases reported in the literature, two of which are localized in the head and neck region. Herein, we report a unique case of solitary fibrous tumor of the liver in a 38-year-old female with predominant multiloculated cystic appearance, and discuss the histopathologic differential diagnosis.
