Abstract
Myelolipoma is a kind of benign lipoma containing myeloid cells. It is a rare type of tumor that typically presents as an occasional adrenal tumor, generally manifesting as a nonfunctional adrenal mass. Although it can occur in extra-adrenal tissues, its occurrence in bone tissue is extremely rare. Most cases are discovered accidentally during physical examinations of adults, and there are currently no reports of cases with pathological fractures as the main symptoms. We present a case of a 15-year-old teenager who developed a pathological fracture caused by femoral myelolipoma. The diagnosis of the specific type of bone tumor of the patient was determined through pathology and imaging. To treat the condition, we utilized a technique known as the "soft drill" to fully access the tumor space, remove the bone septum, and scrape away the diseased tissue. The fracture was then stabilized using a hybrid external fixation. After a 2-year follow-up period, there was no recurrence of the bone tumor. This case is the first case of intraosseous myelolipoma that occurred in a minor with the initial symptom of pathological fracture, filling the gap in our existing body of knowledge and providing a reference for the treatment of this type of intraosseous myelolipoma.

Abstract
Myelolipoma is a benign tumor containing mature adipose cells and a combination of myeloid and erythroid elements. This tumor is typically found in the adrenal glands; however, it has been detected outside the adrenal glands in rare cases. We report an extremely rare case of myelolipoma in the lumbar spine causing significant neural compression due to the involvement of the posterior spinal elements. Given the significant neurological deficit, the patient was surgically managed as soon as possible. Extra-adrenal myelolipomas are rare lesions, and only one case has been reported in the spine so far. However, this diagnosis should be considered in cases with its characteristic imaging features.

Abstract
BACKGROUND Myelolipomas are benign tumors usually found in adrenal glands. They can also be found extra-adrenally, either in 1 or multiple locations. Perinephric transplant myelolipoma has rarely been reported in the English literature. There's only been 1 instance of such a case reported in a kidney transplant patient, which was found on the explanted kidney. We report a case involving an asymptomatic patient with an ill-defined perinephric transplant mass. METHODS The mass was then identified as myelolipoma on biopsy. The patient was then managed conservatively with serial imaging and laboratory testing. RESULTS At the time of our report, the patient continues to have stable renal function and is doing well 24 months after the mass was first identified. CONCLUSIONS We report the first case of perinephric transplant myelolipoma in a patient with ongoing stable renal allograft function. Based on our case report, we recommended that conservative management with serial imaging and routine testing be considered for patients with perinephric transplant myelolipoma.

Abstract
BACKGROUND Presacral myelolipomas form a rare disease and are often found incidentally in imaging diagnostics. CASE PRESENTATION In this study, we report the case of a 71-year-old caucasian female with an incidental finding of a retroperitoneal tumor on magnetic resonance imaging scan. This report aimed at presenting the clinical course of this patient with emphasis on analysis of pathological, clinical, and epidemiological features in a meta-analysis of reported cases. CONCLUSION Presacral myelolipomas are rare and its etiology remains unclear. Surgical resection is indicated in symptomatic lesions and lesions > 4 cm. More clinical and pathological research on this rare entity is warranted.

J Bone Oncol 2022; 35:100438.

Abstract
The first case series with eleven consecutive patients diagnosed with EAMs in the spinal or intraosseous regions. EAMs involving the thoracic vertebral body or the humerus have not previously been reported in the English literature. The surgical outcome and prognosis of EAMs are excellent and surgery can serve as the method of radical treatment.
Purpose Extra-adrenal myelolipomas (EAMs) are rare benign tumors composed of both mature adipose and hematopoietic tissues with unclear etiology. There have been only sporadic case reports about the clinical characteristics and management of EAMs. Here we present our experience and practice in the clinical diagnosis and treatment of 11 consecutive patients with EAMs. Method We retrospectively reviewed 11 consecutive patients, who received surgeries in our department and were confirmed as having EAMs by postoperative histopathology from April 2016 to December 2021. Clinical information and follow-up data of all patients were collected and analyzed afterwards. Results Of the 11 EAM patients (7 male and 4 female) with a mean age of 47.6 years, 3 were asymptomatic and 8 were symptomatic with a mean symptom duration of 6.07 months. EAMs were found in the thoracic spine in 4 cases, paravertebral mediastinal regions in 3 cases, ilium in 2 cases, humerus in 1 case, and rib in 1 case. All patients were initially misdiagnosed as other tumors by radiologists. All 11 patients received gross total excision or curettage with a mean intraoperative blood loss of 781.82 ± 1143.3 ml and a mean operation duration of 180.91 ± 98.41 min. Patients’ Frankel scores and Karnofsky Performance Status score were improved or at least preserved postoperatively. No significant complications occurred postoperatively. All the 11 patients survived, and no local recurrence or distant metastasis occurred during the mean follow-up period of 42.0 months. Conclusion The surgical outcome and prognosis of EAMs are excellent and surgery can serve as the method of radical treatment.

Laparoscopic adrenalectomy for a giant adrenal myelolipoma: A case report. Int J Surg Case Rep 2021; 90:106678.

Abstract
CASE PRESENTATION We describe a case of a patient who presented with a mildly symptomatic, giant myelolipoma which was excised by laparoscopic approach without complications. INTRODUCTION AND IMPORTANCE Adrenal myelolipoma (AML) is a rare tumour composed by fat and myeloid tissues. Usually it is asymptomatic, so the diagnosis is mostly incidental. It is generally located in the right adrenal gland, but it can also be found bilaterally. If its size exceeds 10 cm it is defined as a "giant myelolipoma"; in this case its treatment of choice would be adrenalectomy with an open surgical approach. CLINICAL DISCUSSION Patient's signs and symptoms were mild pain in the right hypochondrium and a positive right Giordano's sign. The mass was detected by a contrast-enhanced CT scan. Once excised it measured 16 cm. CONCLUSION Laparoscopic adrenalectomy for giant myelolipoma is a safe approach if performed by an expert surgeon, with low risk of bleeding and a better outcome for the patient.
