Para-testicular masses are a rare entity, and therefore the diagnosis and management nearly always lead to clinical doubts. Aside from the doubts that arise from these masses being uncommon, it is always necessary to rule out the malignancy process of them. Sexual cord tumors are extremely rare. Testicular fibroma of gonadal stromal origin is a proliferative process that can develop in para-testicular structures. The objective of our study is to present a rare case report of testicular fibroma of gonadal stromal origin as well as the well-documented diagnostic process and the successful therapeutic management that was subsequently carried out. We report a case of a 68-year old male who came in for a consult due to the casual finding of a nodule in his left testicle with normal tumor markers. Ultrasonography showed a nodular image that was well-defined with a diffusely homogeneous echotexture; it was also hypoechoic, vascularized and demonstrated hydrocele. MRI revealed a solid tumor with extrinsic growth to the left testicle and epididymis, and the lesion was relatively hyperintense in T1-weighted image and hypointense in T2. A surgical exeresis of the para-testicular tumor and hydrocelectomy was performed. The pathological anatomy and immunohistochemistry revealed a fibroma of gonadal stromal origin. Histopathological analysis made a diagnosis, although its clinical and radiological characteristics make it one of the differential diagnoses to consider in testicular tumors. Its characteristics, radiological and histopathological, allow for conservative management in clinical practice.
