Incidental adrenal hemangioma clinically suspicious for malignancy: diagnostic considerations and review of the literature. Int J Clin Exp Pathol. 2022;15(11):444-458. Published 2022 Nov 15.https://hdl.handle.net/1805/35957Adrenal hemangiomas are rare lesions often found incidentally during unrelated diagnostic work-up. We report a case of a 67-year-old man with history of hypertension, hyperlipidemia, anemia, arthralgia, joint swelling and unexplained weight loss, which prompted imaging studies. Computed tomography scan revealed a 5.4 cm adrenal mass. The patient had no clinical manifestations of adrenal medullary or cortical hyperfunction. Urine and plasma metanephrines and aldosterone/renin ratio were within normal range. The patient was taking prednisone for hand and ankle swelling, precluding assessment for Cushing syndrome. Given the size of the lesion, the possibility of malignancy was considered, and the patient elected for surgical management. The left adrenalectomy specimen weighed 54 g and revealed a 4.9 cm tan-brown mass with congested cut surface and a thin rim of residual adrenal gland parenchyma. Histologic examination showed thick and thin-walled vessels intermingled with adrenocortical elements at the periphery characteristic of a hemangioma. Surgical resection is the mainstay treatment for large, isolated adrenal masses to exclude malignancy and prevent retroperitoneal hemorrhage. Herein, we report a case of adrenal hemangioma, review a variety of other diagnostic considerations occurring in the adrenal gland, and highlight useful distinguishing features to assist in accurate diagnosis.en-USAttribution-NonCommercial 4.0 InternationalAdrenal glandHemangiomaIncidentalomaIncidental adrenal hemangioma clinically suspicious for malignancy: diagnostic considerations and review of the literatureArticle
