Myelolipoma is an uncommon adrenal tumor composed of a variable mixture of mature adipose tissue and hematopoietic elements that resemble the content of bone marrow. Adrenal glands are the commonest involved site, but other extra-adrenal sites are also reported. Myelolipoma is a benign lesion, usually small and unilateral, asymptomatic, and discovered by accident or at autopsy. Most myelolipoma...

Adrenal collision tumors (ACTs) refer to coexistence of two adjacent, but histologically distinct neoplasms involving the adrenal gland without histologic admixture at interface. ACTs include adenoma with myelolipoma, adenoma with metastases, hemangioma with adenoma, and adrenocortical carcinoma with myelolipoma. In addition, hemorrhage into a pre-existing adrenal mass can mimic an ACT, and it ...

Adrenal myelolipoma is a rare benign neoplasm of mesenchymal origin composed mature fatty tissue and bone marrow elements. It non-functioning tumor, usually asymptomatic commonly detected incidentally during evaluation for unrelated symptoms; hence, it referred to as an “incidentaloma”. Large myelolipomas can cause mass effects vague abdominal pain, spontaneous tumor rupture with massive hemorr...

Myelolipomas are unusual benign tumors or tumor-like lesions, composed of hematopoietic cells and mature adipose tissue. They usually are asymptomatic and behave as non-functioning, unilateral, small adrenal tumors often found incidentally on imaging studies. We report the clinicopathological characteristics of four cases of adrenal myelolipomas treated in our hospital, worth to mention because...

Adrenal myelolipomas are rare benign tumors of the adrenal cortex composed of adipose and hematopoietic cells. They have been postulated to arise from repeated stimulation by stress, inflammation and ACTH oversecretion. Myelolipomas are usually detected incidentally on imaging and do not require any active intervention besides regular follow-up by imaging. However, myelolipomas may insidiously ...

Myelolipomas are rare benign tumors often detected as adrenal masses. Extra-adrenal myelolipomas are encountered even more rarely. The rate of detection of these lesions is increasing with improved radiological techniques. Because of their localization and morphological similarities to well differentiated liposarcomas, extra-adrenal myelolipomas need to be differentiated from other aggressive n...
