Adrenal oncocytic neoplasms (AONs) are a rare group of tumours with a somewhat uncertain natural history and clinical behaviour. Out of 46 cases of AON reported to date, 6 cases were histologically classified as neoplasms with uncertain malignant potential. We report the case of a 35-year-old male with an incidentally-detected large AON with mostly benign morphology and some characteristics which would make its behaviour uncertain.

Oncocytic adrenal cortical carcinoma (ACC) is a rare malignant adrenal cortical tumor with limited documented case reports. Herein, a 65-year-old female patient presented with a large, solid adrenal mass. A diagnosis of oncocytic ACC was rendered with the following tumor characteristics: The tumor entirely consists of diffuse sheets of polygonal cells with bizarre nuclear atypia and deeply eosinophilic cytoplasm.

Oncocytic adrenal neoplasms, defined by ≥90 % of oncocytic cells, are rare. The significance of oncocytic changes within an adrenal neoplasm remains unclear. A retrospective study of adults who underwent adrenalectomy at a large center identified pure oncocytic neoplasms on final pathology (1997-2022).

Background: Adult pure androgen-secreting adrenal tumors (PASATs) are rarely reported and the malignancy of such tumor are difficult to confirm before surgery. Here we report a PASAT demonstrating extremely F-FDG uptake turned out to benign tumor by postoperative pathology examination.

Case Presentation: A 19-year-old adolescent found a tumor measuring 7.

Article Synopsis
  • - Pheochromocytomas are uncommon tumors in the adrenal medulla, making up 10% of adrenal cancers, with oncocytic variants being especially rare, having only 150 documented cases.
  • - The case study highlights a 60-year-old woman with a non-functional adrenal tumor, showcasing the complexities of diagnosing these tumors.
  • - The report stresses the need for thorough histological and immunohistochemical examinations to accurately identify these rare tumors and avoid misdiagnosis.

Oncocytic adenomas are rare benign tumors that typically originate in organs such as the kidneys, thyroid, parathyroid, salivary glands, or pituitary gland. Oncocytic adenoma of the adrenal gland is extremely rare. It often shows heterogeneous, nonspecific features on anatomic imaging, as well as high F-FDG avidity despite its benign nature.
