The lipomas are well-encapsulated, slow-growing, benign fatty tumors. The distribution is defined as being focused in the trunk of the body and extremities. [2] Familial Multiple Lipomatosis can be identified when multiple lipomas occur in multiple family members that span different generations. [2] Some people may have hundreds of lipomas ...
A lipoma is a benign tumor made of fat tissue. [1] They are generally soft to the touch, movable, and painless. [ 1 ] They usually occur just under the skin, but occasionally may be deeper. [ 1 ]
Differential diagnosis include adenoma, myelolipoma, cyst, lipoma, pheochromocytoma, adrenal cancer, metastatic cancer, hyperplasia, and tuberculosis. [3] Some of these lesions are easily identified by radiographic appearance; however, it is often adenoma vs. cancer/metastasis that is most difficult to distinguish.
It is believed that they may begin growth in response to trauma. They are not encapsulated by any sort of covering or sheath around the growth itself, as opposed to other cysts beneath the skin that often are. This means there are loosely defined margins of this lipoma. Despite this, they are known to be benign.
The upper tumor is a benign tumor that is non-invasive. Benign tumors are usually round in shape and encapsulated by fibrous connective tissue. The lower picture depicts a malignant tumor. It is irregularly shaped, vascular, and it is invasive, crossing the basement membrane.
Dercum's disease is a rare condition characterized by multiple painful fatty tumors, called lipomas, that can grow anywhere in subcutaneous fat across the body. [1] Sometimes referred as adiposis dolorosa in medical literature, Dercum’s disease is more of a syndrome than a disease (because it has several clinically recognizable features, signs, and symptoms that are characteristic of it and ...
The presence of eccrine sweat glands are used to distinguish the tumor from a common lipoma. Size and the development of the capsule (tissue surrounding the tumor) can also aid in diagnosis. Size and the development of the capsule (tissue surrounding the tumor) can also aid in diagnosis.
Nevus lipomatosus superficialis (NLS or NLCS, also known as nevus lipomatosis of Hoffman and Zurhelle [1]) is characterized by soft, yellowish papules or cerebriform plaques, usually of the buttock or thigh, less often of the ear or scalp, with a wrinkled rather than warty surface.
