In plain English

This was a case report by a urologist at Ohio State University describing the ultrasound appearance of an adenomatoid tumor found inside the testicle. The article does not mention asbestos or any other exposure. A 65-year-old man was referred to a urologist after a scrotal ultrasound examination found a 1-cm mass within the testicle. Blood levels of two tumor markers, alpha-fetoprotein and human chorionic gonadotropin, were within normal limits. At surgery, a 1-cm firm area was found at the lower pole, entirely within the testicle. The lesion was removed, and the pathologic diagnosis was consistent with an adenomatoid tumor. Citing other sources, the author described adenomatoid tumors as benign, arising from mesothelial tissue, and rarely found inside the testicle. The author stated this was the first published report of their ultrasound appearance. The author concluded that, although benign, the tumor can mimic a malignant testicular tumor on ultrasound and should be considered malignant until proven otherwise.

What the study did and found

• Design: case report (a single patient)
• Who was studied: one 65-year-old man referred to a urologist (Division of Urology, Ohio State University, Columbus, Ohio); dates not given
• Main results:
  • Scrotal ultrasound showed a 1-cm mass inside the testicle in this patient
  • Before surgery, the patient's alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) levels were within normal limits
  • At surgery, the 1-cm lesion at the lower pole of the testicle did not involve the epididymis or the tunica and lay completely within the testicle's parenchyma
  • After excisional biopsy, the pathologic diagnosis was consistent with an adenomatoid tumor
  • The ultrasound image also showed a hydrocele
• The authors' conclusion: The author concluded that ultrasound cannot tell this benign tumor apart from a malignant intratesticular lesion, and that these tumors should be considered malignant until proven otherwise
