Objective:
Benign testicular proliferative processes are known by the name of pseudotumors, because currently they are not considered real neoplasias. The paratesticular fibrous pseudotumor (PFP) is a rare entity the definition and etiopathogenesis of which is under great confusion. It is a process that misleads the clinical because they simulate neoplasias. This paper aims to help a better knowledge of this non-tumoral process and to avoid diagnostic confusions.
Methods/Results:
We review our series of PFP (three cases), which can be considered significant due to its oddity. We analyze the clinical picture, its behavior, imaging diagnostic tests, operative findings and outcomes.
Conclusions:
PFP is a rare entity which may misleads the clinical because it may be diagnosed as a neoplasia and lead to aggressive treatment (orchiectomy) which in case of a proper diagnosis could be avoided. The analysis of our series of three cases, with their contribution, and a literature review may help the clinical practice of urologists by recognizing this disease.
