Para-testicular fibrous pseudotumors (PFP) are rare benign reactive lesions comprising of 6 % of para-testicular masses. Often misdiagnosed as malignant due to clinical and radiological overlap, they are frequently treated with aggressive surgery. We report a case of a 70-year-old male with a left inguinal swelling diagnosed post-orchidectomy as PFP. Histopathology revealed collagen-rich fibrotic tissue with lymphoplasmacytic infiltrates and IgG4-positive plasma cells. While PFP treatment requires surgical resection, testicle-sparing procedures with intraoperative frozen section assessment may prevent unnecessary orchidectomy. Further studies are needed to establish diagnostic protocols and explore the association between PFP and IgG4-related diseases.

Background: Ganglioneuromas (GNs) are composed of mature ganglion cells and Schwann cells with a fibrous stroma; GNs are most often observed in children and young adults. The majority of non-cranial GNs are located in the retroperitoneum and posterior mediastinum. Other reported rare sites include the adrenal gland, small intestine, colon and urinary bladder.

Introduction: Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear.
Case Report: A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis.

Twenty two patients with tumours or tumour-like conditions of the para-testicular region (PTR) were diagnosed over a 5 year period. Of these, 16 (73%) were benign with only one true neoplasm (papillary cystadenoma). The tumour-like conditions were comprised of 6 cases of adenomatous hyperplasia of epididymis, 4 cases of spermatic granuloma, 2 cases each of spermatocele and nodular-fibrous proliferation and one mesothelial cyst.
