Xanthogranulomatous epididymitis is extremely uncommon inflammatory disease of the epididymis that may result in massive destruction of the organ. It's clinical manifestation mimics epididymal tumor or abscess, which does not allow easy discrimination between theses diseases. We report here on a case of xanthogranulomatous epididymitis in a 69 years old man that, did not respond to antibiotic therapy.

Testis ultrasonography shows a hetero echogenic mass on the tail portion of the left epididymis and a multiple septated hydrocele with echogenic debris surrounding the testis.

(A) Microphotography shows formation of inflammatory granulomatous tissue accompanied by abundant lymphocytes, neutrophils and plasma cells (H&E, ×40). (B) Microphotography shows numerous lipid-laden macrophages having abundant cytoplasm that contains clear to foamy vacuoles (H&E, ×400).
