Intralumenal Vesicles and Multivesicular Bodies

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Lipid Absorption

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Lipid Catabolism

Lipid Catabolism

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Background:

Intravascular lipomas are rare benign adipose tumors originating from blood vessel walls, most commonly veins.
While typically asymptomatic and rare in lower extremities, large lipomas can cause venous obstruction symptoms like swelling and pain.

Purpose of the Study:

To report a rare case of a symptomatic intravascular lipoma in the common femoral vein of the lower extremity.
To discuss the diagnostic challenges and differential diagnoses, including atypical lipomatous tumors and leiomyosarcoma.

Main Methods:

Case report of a 75-year-old male with lower extremity swelling and ulcers.
Preoperative imaging for lesion characterization.
Surgical resection and pathological confirmation.

Main Results:

A symptomatic intravascular lipoma was identified in the right common femoral vein.
The tumor caused venous obstruction, leading to patient symptoms.
Surgical resection was successfully performed.

Conclusions:

Symptomatic intravascular lipomas of lower extremity veins are rare but require consideration in differential diagnosis.
Comprehensive preoperative imaging is crucial for accurate characterization.
Distinguishing benign lipomas from malignant counterparts like liposarcoma and leiomyosarcoma is essential.
