or tumor,
tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair

Lipoma

 

a limited benign tumor (sometimes multiple) consisting of fatty tissue.

Lipomas generally develop on the back, neck, and anterior abdominal wall. They vary in density and in size, from that of a hazelnut to that of the head of a grown man. Lipomas usually do not impair any function; generally, they are removed for cosmetic reasons.

(23) This suggests that the pathogenesis of angiolipoma may be different from that of ordinary lipoma. Angiolipoma seems to show aberrant expression of full-length HMGA2, although at levels lower than in lipoma with 12q rearrangements.
Because investigations carried out on the lesion, including Fine Needle Aspirate Cytology (FNA) and CT scan suggested a diagnosis of a lipoma, we expected a straight forward excision of the lesion.
Uncommon exceptions to this norm include infiltrative lipomas and myelolipomas.
(6) Infiltrative lipomas are benign and locally aggressive lipocytic tumors invading adjacent tissues, such as muscle, fascia, nerve, joint capsule, and bone.
Lipoma is a universal tumor and accounts for approximately 16% of soft tissue mesenchymal tumors.2 These tumors consist of cells resembling mature fat cells and may occur in subcutaneous, inter-muscular or intra-muscular locations.4 Palmar region has a good amount of fat; however lipomas are only rarely seen at this location.4 Lipomas have the ability to insinuate themselves into small recesses and thus produce tumors of any size or shape by infiltration of spaces not tightly bound by protecting sheaths as fascia.
Endoscopic resection of gastrointestinal lipomas: a single-centerexperience.
She had two caesarean sections and excision of multiple benign subcutaneous lipomas. Her family history was unremarkable, except for her mother's diffuse lipomatosis.
For tonsillar lipoma cases, it was reported that excision of the mass would be sufficient, with no need for a tonsillectomy (5).
When you find a lipoma, you might be concerned that you have cancer.
Lipomas in general often present in the fifth or sixth decade of life (1, 2, 5-7).
There is a controversy regarding whether giant lipomas (i.e., in particular those >10 cm or weighing >1000 g) are typical lipomas or liposarcomas.
