Overview
Leptomyelolipoma is an extremely rare type of tumor that has been classified as an obsolete term in medical databases, meaning the condition has been reclassified or merged with other related diagnoses over time. This tumor is a variant of myelolipoma, which is a benign (non-cancerous) growth made up of a mixture of fat tissue and blood-forming (hematopoietic) cells, similar to what is normally found in bone marrow. Leptomyelolipoma specifically refers to a form where the fat component is more prominent and the blood-forming tissue is relatively sparse or thin. These tumors are most commonly found in the adrenal glands, which sit on top of the kidneys, but they can occasionally occur in other locations in the body. Most people with this type of tumor have no symptoms at all, and the growth is often discovered by accident during imaging studies done for other reasons. When symptoms do occur, they may include mild abdominal or flank pain, a feeling of fullness, or discomfort if the tumor grows large enough to press on nearby structures. Because this is a benign condition, the outlook is generally very good. Treatment is usually not needed unless the tumor causes symptoms or grows significantly, in which case surgical removal may be considered. Since this term is now considered obsolete, patients may find their condition described under the broader category of myelolipoma or adrenal myelolipoma in current medical literature.
