Spermatocytic Tumor of the Left Testis: A Case Report

Background Spermatocytic tumor (ST) is a rare testicular neoplasm distinct from classical seminoma, with unique clinical, pathological, and prognostic features. It constitutes less than 1% of testicular germ cell tumors. Clinically, ST presents as a slow-growing, painless testicular mass and is rarely associated with systemic symptoms or elevated tumor markers. Its rarity and overlapping characteristics with other germ cell tumors pose diagnostic and management challenges. Case Presentation A 34-year-old male presented with a gradually enlarging left testicular swelling over five to six months. Surgical high inguinal orchiectomy followed by histopathology confirmed a spermatocytic tumor confined to the testis, with typical immunohistochemical markers. Despite initially planned surveillance, subsequent cytology suggested seminoma leading to initiation of carboplatin chemotherapy. Conclusion The case underscores the importance of detailed histopathological and immunohistochemical evaluation for accurate diagnosis of spermatocytic tumor, avoiding overtreatment. The prognosis remains excellent following orchiectomy for localized disease, highlighting the need for individualized multidisciplinary management.
