Abstract

Adenomatoid tumors are rare, benign mesotheliomas that usually are associated with genito-urinary tract. The suprarenal occurrence of this tumor is uncommon. We present such a case and review the origin of the adenomatoid tumor.

In plain English

This article was a case report from Madigan Army Medical Center in Tacoma, Washington. It described one patient with an adenomatoid tumor, which the authors called a rare, benign type of mesothelioma that usually occurs in the genital and urinary tract. The tumor sat above the kidney, an uncommon site. A 36-year-old white man had two episodes of painless blood in the urine. Scans showed a large mass above the left kidney, measuring 8 by 10 cm on CT. Preoperative laboratory tests were normal. Surgeons removed the encapsulated mass, and the specimen measured 11 cm. Under the microscope the tumor showed no nuclear atypia and no mitotic figures. Electron microscopy found features the authors described as characteristic of mesothelial cells. Eight months after surgery the patient was well, with no sign of recurrence. The authors also reviewed earlier writing on where these tumors come from. They concluded that their case was an unusual presentation of a rare tumor that is now accepted as arising from mesothelium. The article did not mention asbestos or any exposure history for the patient.

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 (single patient), with a discussion reviewing earlier literature on the tumor's origin
• Who was studied: One 36-year-old white man treated at Madigan Army Medical Center, Tacoma, Washington; dates of care not given
• Main results:
  • CT showed an 8 by 10 cm complex mass above the left kidney without calcifications
  • Preoperative laboratory evaluation of the patient was normal
  • The surgical specimen measured 11 cm
  • The tumor showed no nuclear atypia and no mitotic figures
  • Electron microscopy showed features (microvilli, desmosome-like junctions, tonofilaments) that the authors described as characteristic of mesothelial cells
  • The patient was well with no recurrence 8 months after surgery
• The authors' conclusion: The authors concluded that their case of a periadrenal adenomatoid tumor was an unusual presentation of a rare tumor that is now accepted as being of mesothelial origin
