Abstract

A case is reported of an adenomatoid tumor of the epididymis. A discussion of the appropriate differential of mass of the epididymis as well as a review of adenomatoid tumors per se and their occurrence in the scrotum are presented.

In plain English

This article was a case report, published in 1992, about one patient with an adenomatoid tumor of the epididymis, inside the scrotum. The article does not mention asbestos or any occupational or other exposure. The patient was a 60-year-old white man with a firm, slightly tender mass in the right scrotum and a history of scrotal pain and discomfort. An ultrasound scan showed a cyst about 0.8 cm across and a 2-cm solid mass with homogeneous medium to high level echoes replacing the tail of the right epididymis. Surgery to remove the right testis (a right radical orchiectomy) revealed a 2-cm encapsulated, firm, rubbery, white, round mass. Tissue examination was consistent with adenomatoid tumor. Counting this case, the authors listed 10 adenomatoid scrotal tumors reported by ultrasound. They noted that the ultrasound appearance varied across the limited number of reports. The authors concluded that this benign tumor, which looked bright (hyperechoic) and uniform on ultrasound, supported an earlier suggestion that scrotal masses with that appearance might be considered benign.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

What the study did and found

• Design: case report
• Who was studied: One 60-year-old white man with a firm, slightly tender mass in the right scrotum and a history of scrotal pain and discomfort; no history of trauma
• Main results:
  • In this patient, high-resolution ultrasound showed an epididymal cyst about 0.8 cm in diameter and a 2-cm well-circumscribed solid mass with homogeneous medium to high level echoes, replacing the tail of the right epididymis
  • In this patient, right radical orchiectomy revealed a 2-cm encapsulated, firm, rubbery, white, spherical mass in the globus minor
  • In this patient, the pathologic section showed cystic spaces lined by flattened cells surrounded by fibrous stroma and bundles of smooth muscle, consistent with adenomatoid tumor
  • Including this case, the authors counted 10 adenomatoid scrotal tumors reported by sonography
• The authors' conclusion: The authors concluded that this benign epididymal adenomatoid tumor, which was hyperechoic and homogeneous on sonography, supported an earlier hypothesis that hyperechoic, homogeneous scrotal masses might be considered benign
• Limitations the authors state:
  • The authors noted that only a limited number of reports are available, and that in these reports the sonographic appearance of the tumor varies in echogenicity
