Introduction: Adrenal myelolipomas and lipomas are extremely rare benign tumors. They are usually asymptomatic and in most cases are incidentally found at radiological examinations or autopsy. Symptoms such as abdominal pain and increasing girth occur only when the tumor grows large. Objectives: To evaluate and treat this situation. Subjects: We report the case of a giant adrenal myelolipoma with dimensions of 9 x 8 x 8cm and a giant adrenal lipoma with dimensions of 20 x16 x 12cm. Firstly, in a 48 year old man admitted to hospital on the 18 January 2005 without symtoms of adrenal lipoma or adrenal mylolipoma and another one is a 25 year old man who was hospitalized on the 8 December, 2004 with pain in the right hip since two months prior, normal blood pressure and undiscovered tumor by hand. Result: Other tests were normal. Looking at the CT scan images, a dark and consistent block located between the liver and right kidney can be seen. It pushed and turned the right kidney. Both of them were resected by laparoscopy. Conclusion: We discuss the prevalence, clinical features, diagnosis and treatment of these uncommon tumors.
Adrenal myelolipoma and lipoma

The identification of fat density by unenhanced CT within an adrenal mass is highly suggestive of myelolipoma. Adrenal collision tumors which involve a myelolipoma are uncommon, though the involvement of adenomas and pheochromocytomas has been reported. We describe a case in which an adrenal collision tumor consisting of an adrenocortical carcinoma and myelolipoma, presented as a large fat-containing adrenal soft tissue mass.

Adrenal myelolipomas are rare benign tumors consisting of mature fat and hematopoietic elements resembling bone marrow. Due to the frequent use of ultrasound and computerized tomography their presence is now more frequently discovered. Although these tumors are usually asymptomatic and only found incidentally at autopsy, they can cause local symptomes or hemorrhage requiring surgical excision. We present the case of a large surgically and histologically confirmed, adrenal myelolipoma with retroperitoneal hemorrhage due to spontaneous rupture in a 32-year old man.

Extra-adrenal myelolipoma is a rare benign tumor which can occur in the abdomen, thorax, or even in the face. We present a case of 58-year-old woman patient with thoracic myelolipoma, which has manifested as three paravertebral masses at the level of T9 and T10. The computed tomography scan showed heterogenous enhancing masses, which contained fat component. She underwent video-assisted thoracoscopic surgery, and the pathologic examination revealed adipose tissue with many hematopoietic cells, consistent with myelolipoma.

PURPOSE: In this study, we report on our initial experience using the da Vinci-S® robotic surgical system in performance of laparoscopic adrenalectomy. METHODS: Fifteen patients, 11 with left adrenal tumors and four with right adrenal tumors, underwent robotic adrenalectomies using the lateral transperitoneal approach with the da Vinci-S® surgical system at the Korea University Anam Hospital, Seoul, Korea, between October 2009 and May 2012. RESULTS: The mean age of the patients was 45.5 (22~61) years, and the mean body mass index was 23.81 (18.0~28.57) kg/m². Eleven left adrenalectomies, four for primary aldosteronisms, four for pheochromocytomas, two for primary adrenal Cushing's adenoma, and one for myelolipoma, and four right adrenalectomies, two for the primary adrenal Cushing's adenomas, one for pheochromocytoma, and one for primary aldosteronism, were performed robotically. There was no conversion to traditional laparoscopic or open surgery. The mean size of the tumor was 2.54 (1.0~5.5) cm. The mean operative time was 208.2 (120~320) minutes, and the mean console time was 127.6 (75~212) minutes. No major postoperative morbidity was observed, and the mean length of hospital stay was 5.86 days. CONCLUSION: We found that the robotic systems, with magnified stereoscopic three-dimensional vision, elimination of tremor, and the ability to articulate and rotate the instruments, were ideal surgical tools for operation of adrenal lesion. Robotic adrenalectomy may be a safe and effective alternative to traditional laparoscopic adrenalectomy.

Adrenal myelolipoma is a rare, nonfunctional benign tumor that is composed of mature adipose tissue and hematopoietic elements. In the past, these tumors were accidentally discovered at autopsy. Today, they are found much more frequently and incidentally, mainly because of the widespread use of noninvasive imaging with ultrasonography, computed tomography, and magnetic resonance imaging. Most lesions are asymptomatic, small, and unilateral, but a number of bilateral tumors have been reported. We report here on a case of a 48-year-old man with incidentally found myelolipomas of both adrenal glands. In particular, a giant myelolipoma of the left adrenal gland was treated by transperitoneal laparoscopic adrenalectomy.

PURPOSE: Benign adrenal tumors other than hyper-functioning tumor and non-functioning cortical adenoma are extremely rare. The purpose of this study is to review the clinical features of these rare benign adrenal tumors and to analyze their prevalence and the proper surgical approach for them. METHODS: Among patients who underwent adrenalectomy in Samsung Medical Center, between 1997 and 2013, patients with benign adrenal tumor except non-functioning cortical adenoma, malignancy, and hyper-functioning tumor such as pheochromocytoma, aldosteronoma, and cortisol producing tumor were included. Clinical details, radiologic findings and pathologic findings as well as data associated with the surgical procedure were analyzed retrospectively. RESULTS: The percentage of these tumors among 703 surgically removed adrenal tumors was 10.7% (75 cases). They included 30 adrenal cysts, 18 ganglioneuromas, 11 myelolipomas, seven schwannomas, and the other six were rare adrenal tumors. Approximately 40% of the patients were operated under a diagnosis different from original tumors. Operation time and hospital stay of patients who underwent laparoscopic adrenalectomy were shorter than those of patients who underwent open adrenalectomy. CONCLUSION: These benign adrenal tumors are very rare and difficult to diagnose preoperatively. For the surgical treatment of these tumors, laparoscopic adrenalectomy is more preferable to conventional open adrenalectomy.
