= Abstract =We recently encountered a very rare case of torsion of an intrascrotal testicular tumor in a 26-year-old male. Unlike the intra-abdominal undescended testis, intrascrotal spermatic cord torsion associated with a testicular tumor has rarely been reported. We write to report a case of intrascrotal spermatic cord torsion accompanied by a testicular tumor that had been overlooked preoperatively.
Key Words: Spermatic cord torsion, SeminomaTorsion usually occurs in the absence of a precipitating event, such as trauma.1 Predisposing factors for testicular torsion are an increase of testicular volume, history of cryptorchidism, and testicular tumor. 2 Most reports of the spermatic cord torsion associated with testicular tumors, especially seminoma, are localized in the intra-abdominal testis. We report this rare case of intrascrotal spermatic cord torsion associated with an initially overlooked seminoma for the first time in South Korea.
Case ReportA twenty-six-year-old male patient was referred to the department of urology from the department of emergency medicine due to the abrupt onset of left scrotal pain and swelling. He had never noticed enlargement of scrotum before nor did he have a history of scrotal pain. On physical examination, the testis was enlarged with severe tenderness and the absence of the cremasteric reflex. On gray-scale sonography, the testicle showed heterogeneous echogenicity composed mainly of a hypoechoic lesion and enlargement of the epididymis (Fig. 1A, 1B). Doppler sonography revealed no blood flow. We decided to perform emergent detorsion. Upon detorsion, his pain was relieved and Doppler sonography showed a resumption of blood flow. The emergency operation planned was bilateral orchiopexy performed through a scrotal midline incision. In the operation room, the spermatic cord was edematous due to prolonged torsion and the enlarged testicle had bluish mass-like lesions in seminiferous tubules seen through the transparent tunica albuginea with an enlarged and congested epididymis (Fig. 2). Frozen pathological analysis of the bluish masses during operation revealed seminoma. An additional inguinal incision for an orchiectomy and the final pathological analysis was consistent with seminoma confined to the testis (Fig. 3). There was no evidence of distant metastasis on postoperative abdomino-pelvic
