Intrascrotal benign fibrous proliferations are uncommon and mostly arise from paratesticular region falling into the category of fibrous pseudotumor which is characterized by nodular growth composed of probably reactive proliferation of fibroblasts and inflammatory cells. Although benign, this often clinically mimics intrascrotal malignancy and usually remains undiagnosed preoperatively. Here, ...

We will describe a case of a patient diagnosed with a rare identity of a benign lesion, "reactive nodular fibrous pseudotumor" (RNFP). It is a tumor which preoperatively can present as a malignant tumor and is only reported in 19 cases. According to the very limited amount of information on this tumor in the literature it is mostly seen after trauma or intraperitoneal inflammation. Our case is ...

A 32-year-old man presented with a complaint of painless palpable mass of the left scrotal content. Based on the preoperative diagnosis of scrotal or spermatic cordal benign tumor, local excision was performed. The histological diagnosis was scrotal fibrous pseudotumor. In Japan, only 35 cases of fibrous pseudotumor of the scrotum have been reported including our case. Orchiectomy was performed...
