[Extra neural perineurioma: an unusal renal tumor].
Neoplasia composed of perineurial cells include intraneural and extraneural perineurioma. The latter is a rare tumor often observed in cutaneous tissue. We report a case of extraneural perineurioma developed at the upper pole of the left kidney and found during the assessment of a repetitive urinary tract infection in a 26 years old man. The tumor was composed of spindle-shaped cells arranged in a storiform pattern. The immunohistochemical pattern was EMA+, PS100-.
