Tumefactive fibroinflammatory lesion of the lower extremity: a case report.

We report a case of tumefactive fibroinflammatory lesion located in the anterior, extracapsular part of the right knee, not responding to the conservative treatment. We discuss about the difficulty of the clinical diagnosis of this lesion. In the present case, only the histopathological characteristics confirmed the presence of fibroadipose and inflammatory tissue with lymphocytes and inflammatory cells. After 1 year from the surgical treatment, the patient was completely healed.
