Adenomatoid tumor of the adrenal gland: unexpected guest

Abstract

Abstract Adenomatoid tumor (AT) is a benign growth that originates from mesothelial cells. Typically, it encompasses the uterus, fallopian tubes, and paratesticular area. One-third of all AT is in paratesticular area, and it accounts for 60% of all benign paratesticular tumors. ATs have been seldom reported as a case report in adrenal gland, liver, pleura, and mediastinal cavity. To date, English literature has only documented 46 instances of adrenal AT. We present the occurrence of a new clinically unexpected case of adrenal AT in a 37-year-old male patient. Computed tomography (CT scan) incidentally revealed the presence of a tumor. To the best of our knowledge, this is the first reported instance of primary adrenal gland AT reported in Saudi Arabia and the 47th instance worldwide in the English-based published literature. It is crucial to thoroughly investigate these tumors, utilizing techniques such as histopathological analysis and immunohistochemical staining to correctly diagnose AT.
