Paratesticular fibrous pseudotumor.

Area of Science:

• Urology
• Pathology
• Surgical Oncology

Background:

• Fibrous pseudotumor is a rare, benign proliferation that can affect various organs.
• The tunica vaginalis, a serous sac surrounding the testis, is an uncommon site for this condition.
• Accurate diagnosis is crucial for appropriate management.

Observation:

• A rare case of fibrous pseudotumor of the tunica vaginalis is presented.
• The clinical presentation, histopathologic findings, and imaging characteristics are discussed.
• The lesion mimicked a neoplastic process, highlighting diagnostic challenges.

Findings:

• Histopathologic examination revealed characteristic features of fibrous pseudotumor, including fibroblast proliferation and inflammatory cells.
• Immunohistochemistry supported the benign nature of the proliferation.
• No evidence of malignancy was found.

Implications:

• Preoperative identification of fibrous pseudotumor of the tunica vaginalis is essential.
• A thorough understanding of this benign entity facilitates an organ-sparing surgical approach, preserving testicular function.
• This case underscores the importance of considering benign mimics in the differential diagnosis of scrotal masses.
