Supernumerary testis, also known as polyorchidism, is a condition characterized by the presence of more than two testes. Another condition of the testes is seminoma, a common cause of testicular germ cell tumor. A 35-year-old male was transferred to our hospital with a diagnosis of abdominal mass causing abdominal pain. On physical exam, he had a palpable undescended left testicle in the left inguinal canal, which was determined to be seminoma. The mass was surgically removed, and the patient underwent chemotherapy. The report discusses his workup, treatment, and outcome. This case illustrates an unusual presentation of supernumerary testis with the extra testis harboring a seminoma. When presented with a case of testicular cancer with no tumor noted in the palpable testes, malignancy in an extranumerary testicle should be considered in the differential.
额外睾丸，也称为多睾症，是一种以存在两个以上睾丸为特征的病症。睾丸的另一种病症是精原细胞瘤，它是睾丸生殖细胞肿瘤的常见病因。一名35岁男性因诊断为腹部肿块伴腹痛被转至我院。体格检查时，在左侧腹股沟管可触及一个未降入阴囊的左侧睾丸，经诊断为精原细胞瘤。该肿块被手术切除，患者接受了化疗。报告讨论了他的检查、治疗及结果。本病例说明了额外睾丸伴其中一个额外睾丸患有精原细胞瘤的不寻常表现。当遇到一例睾丸癌患者，在可触及的睾丸中未发现肿瘤时，鉴别诊断应考虑额外睾丸发生恶性肿瘤的可能性。
