Spermatocytic seminoma is a uncommon subtype of testicular germ cell tumor and comprised 1.1% of all seminoma and the age standardized incidence rate was 0.4 per million. Age at diagnosis ranged from 19 to 92 years with a mean of 53.5 years. Spermatocytic seminoma is a testicular neoplasm which presents as a slow growing mass with or without pain. It arises more commonly in the right testis, and serum tumor markers are always negative. Metastasis is extremely rare, so surveillance alone is sufficient postoperative management.
A 54-year-old patient visited our urology clinic due to a palpable right testicular mass with mild soreness for 3 days. Scrotal echo showed a 1.6 cm hypervascular mass at the upper pole of right testis. Magnetic resonance imaging revealed right testicular tumor with suspicious involvement of tunica albuginea. Serum alpha fetoprotein and beta HCG levels were normal. Preoperative abdominal CT scan demonstrated no inguinal, pelvic or paraaortic lymphadenopathy.
 He was admitted for right radical orchiectomy and pathology confirmed spermatocytic seminoma (pT1). He recovered uneventfully and was discharged home 2 days after operation. We report the rare case and review the literature of spermatocytic seminoma.
