“…The tumour has a significant male predilection. Adrenal adenomatoid tumours y are mostly asymptomatic but could produce hormone-related symptoms [28,29]. They show similar morphology as in adenomatoid tumours in the other portion of urogenital tract except that stromal smooth muscle proliferation is often less common.…”

The fourth edition of the World Health Organization (WHO) classification of endocrine tumours contains substantial new findings for the adrenal tumours. The tumours are presented in two chapters labelled as "Tumours of the adrenal cortex" and "Tumours of the adrenal medulla and extra-adrenal paraganglia." Tumours of the adrenal cortex are classified as cortical carcinoma, cortical adenoma, sex cord stromal tumours, adenomatoid tumour, mesenchymal and stromal tumours (myelolipoma and schwannoma), haematological tumours, and secondary tumours. Amongst them, schwannoma and haematological tumours are newly documented. The major updates in adrenal cortical lesions are noted in the genetics of the cortical carcinoma and cortical adenoma based on the data from The Cancer Genome Atlas (TCGA). Also, a system for differentiation of oncocytoma from oncocytic cortical carcinoma is adopted. Tumours of the adrenal medulla and extra-adrenal paraganglia comprise pheochromocytoma, paraganglioma (head and neck paraganglioma and sympathetic paraganglioma), neuroblastic tumours (neuroblastoma, nodular ganglioneuroblastoma, intermixed ganglioneuroblastoma, and ganglioneuroma), composite pheochromocytoma, and composite paraganglioma. In this group, neuroblastic tumours are newly included in the classification. The clinical features, histology, associated pathologies, genetics, and predictive factors of pheochromocytoma and paraganglioma are the main changes introduced in this chapter of WHO classification of endocrine tumours. The term "metastatic pheochromocytoma/paraganglioma" is used to replace "malignant pheochromocytoma/paraganglioma." Also, composite pheochromocytoma and composite paraganglioma are now documented in separate sections instead of one. Overall, the new classification incorporated new data on pathology, clinical behaviour, and genetics of the adrenal tumours that are important for current management of patients with these tumours.

“…Fewer than 40 primary tumors have been reported in the adrenal, with a male predilection and an age range of 24-64 years of age. Typically, these tumors are seen on the left side more often than the right and may be incidentally discovered, although pain and hematuria have been reported (67) (Fig 14).…”

Advanced imaging often reveals adrenal tumors and tumor-like conditions in both symptomatic and asymptomatic patients. When adrenal disease is clinically suspected, cross-sectional imaging can be helpful in evaluating the etiology of the patient's symptoms. When adrenal disease is incidentally identified, what the clinician and patient really want to know is whether the findings are benign or malignant, as this ultimately will affect their next step in management. Using radiologic-pathologic correlation, we broadly classify common, uncommon, and rare tumors and tumor-like conditions that can occur in the adrenal as benign or malignant. This classification follows predominant trends in observed biologic behavior while acknowledging those tumors that may behave in the minority in an unpredictable manner. We review the clinical background and presentation of functional adrenal tumors including Conn syndrome, Cushing syndrome, and catecholamine-secreting tumors, as well as their relationship with adrenal anatomy. We discuss a variety of benign tumors, including adrenal cortical adenoma (including oncocytoma) and pheochromocytoma, as well as uncommonly and rarely encountered tumors such as myelolipoma, hemangioma, lymphangioma, schwannoma, ganglioneuroma, and adenomatoid tumor. A variety of tumefactive but nonneoplastic lesions are addressed, including adrenal cortical hyperplasia, adrenal hemorrhage, adrenal cysts, and infections. Malignant tumors discussed include adrenal cortical carcinoma, the rare malignant pheochromocytoma, lymphoma, metastases, and sarcomas. For each tumor and tumor-like lesion, the clinical presentation, epidemiology, key imaging findings, diagnostic differential considerations, and management options are briefly addressed. Finally, an approach to the workup of suspected or incidentally discovered tumors is presented based on a selected literature survey and our clinical experience. Radiologists play an important role in identification and diagnosis of adrenal tumors and tumor-like conditions in both symptomatic and asymptomatic patients.

“…Adrenal adenomatoid tumors are derived from mesothelial rests in the adrenal gland. 1,2 During embryogenesis there is close relationship between the adrenal glands and the Mullerian tract, so mesothelial rests could be present in this unexpected site such as the adrenal gland. These tumors are mostly nonfunctional, asymptomatic and discovered incidentally, during radiological examinations, surgery or on autopsy.…”

Background Adenomatoid tumours are presented as rare neoplasms of mesothelian origin, with different location, which can easily mimic specific diseases presented as adrenal incidantelomas, eg pheochromytoma, Cushing syndrome or adrenal carcinoma. The incidence does not allow providing specific pathognomic characteristics and the differential diagnosis may be proven challenging. Case presentation NK, a 49 year old mechanic engineer, without remarkable medical history, non smoker, was examined by cardiologist (IM) & pneumologist (NB) due to atypical chest & mostly back pain., after having visited public hospital (2th 2017). Where blood count, troponine, biochemical analysis, chest Xray & heart doppler revealed anything notable. The chest ct scan ordered by NB revealed multiple shadings up to 3mm, propably as remains of lung infection. The main finding was a large hypodense mass 8*4 cm at the right adrenal location, probably outrived from it.
