ALVAREZ MUGICA, Miguel et al. Solitary pararenal fibrous tumor. Arch. Esp. Urol. [online]. 2006, vol.59, n.2, pp.195-198. ISSN 0004-0614.
Objectives: To report a rare clinical case of solitary pararenal fibrous tumor, analyzing its pathological characteristics and prognosis by a bibliographic review. Methods/Results: We present the case of a 36-year-old male consulting for right flank colic pain, which was diagnosed of a solid mass in the lower pole of the right kidney and underwent right radical nephrectomy. Pathological study of the surgical specimen showed the presence of a solitary pararenal fibrous tumor. Conclusions: Solitary fibrous tumor is a rare neoplasia, being its pararenal localization even rarer. It is a tumor with benign behavior in up to 90% of the cases. The immunohistochemical study is the key to diagnosis.
