Developing lower pole desmoid fibrosis in patient with known case of upper pole renal cell carcinoma after partial nephrectomy

Abstract

Desmoid fibromatosis (DF) is an extremely rare tumor, which is locally aggressive in nature with no metastatic potential. Presenting symptoms depend on tumor size, site and progression speed. Most commonly occur sporadically, or associated with familial adenomatous polyposis (FAP). Factors may contribute to develop DF are trauma or surgical incision. In this article, we report a 41-years old male, which had partial upper pole nephrectomy, and developed lower pole desmoid fibrosis proven by histopathology.To our best knowledge, there are no article discussed the 2 different tumors occur in the same kidney at 2 different locations.
