Anastomosing hemangioma of adrenal gland: rare benign vascular tumor

Anastomosing hemangioma of the adrenal gland is a rare benign vascular neoplasm that often presents incidentally during imaging for unrelated conditions. This tumor may mimic more aggressive lesions, such as angiosarcoma, due to its vascular nature; however, it is characterized by a distinctive lobular architecture and the absence of significant cytologic atypia. Typically found in older patients, anastomosing hemangiomas range in size and are usually solitary. The patient is 49-year-old gentleman who underwent laparoscopic left adrenalectomy for incidentally found 5 cm left adrenal tumor. Histologically, it was confirmed as anastomosing hemangioma with proliferating size spaced lined by epithelium with hobnail morphology. This case aims to contribute to sparse literature for future imaging findings, histology findings, and options of management: observation vs. operative.
