Lipoma is the most common neoplasm of mesenchyme, and several subtypes have been described that vary according to their location and the presence of other tissue elements. Angiomyxolipoma is a very rare variant that consists of an admixture of adipose and myxoid elements with numerous vascular structures. It should be differentiated from other subtypes of benign and malignant lipomas. Here the ...

Aging is associated with important changes in the cardiovascular system. A key feature is the development of endothelial dysfunction, with the concomitance of enhanced vascular tone, increased production of reactive oxygen species, a fall in fibrinolytic capacity and a rise in vascular and blood procoagulant activity (1). In parallel, the ability to repair vessel injury is impaired by a decreas...

PURPOSE This study was performed to evaluate the feasibility of visualizing soft tissue lesions and vascular structures using contrast-enhanced cone-beam computed tomography (CE-CBCT) after the intravenous administration of a contrast medium in an animal model. MATERIALS AND METHODS CBCT was performed on six rabbits after a contrast medium was administered using an injection dose of 2 mL/kg b...

During the past decade, it has become apparent that reactive oxygen species play a critical role in the genesis of many vascular diseases. The superoxide anion is among the most important of these, not only because of its rapid reaction with NO but also because it serves as a progenitor for many other reactive oxygen species. Although there are many approaches to detecting and quantifying super...

Atherosclerosis is a multifactorial disease induced by the effects of various risk factors on appropriate genetic backgrounds. It is characterized by vascular areas containing mononuclear and proliferating smooth muscle cells,as well as extracellularmatrix (ECM)2 components resulting in hardening and thickening (arteriosclerosis) of the arterial wall. In a strict sense, atherosclerotic lesions ...

Background & Objective: Recent studies from gene profiling have revealed some genes that are overexpressed in the epithelial-mesenchymal transition (EMT) process and are responsible for its initiation and activation resulting in tumor progression and metastasis. The present study aimed to assess the role of genes involved in the EMT process and the association of these genes wi...

introduction: klippel–trenaunay syndrome (kts) is a rare congenital mesodermal abnormality characterized by varicose veins, cutaneous capillary malformation, as well as bone and soft tissue hypertrophy. case report: a 2-week-old female infant presented to our clinic because of vascular nevus and progressive enlargement of her right extremities and trunk since birth. the patient was treated with...

background: rhabdomyosarcoma (rms) is one of the common malignant tumors in infants and children, but it is extremely rare in the kidney. in this paper, we present a case of rms the kidney of a child. case presentation: a 6-month old girl presented with agitation, low fever and abdominal distention which started 5 days ago. on physical examination, the infant had a large and firm soft tissue ma...
