A rare case is described of an intramural sarcoma of the right common carotid artery coexisting with adventitial inflammation and fibrosis, resembling 'inflammatory aneurysm', which was resected from a 33-year-old Japanese woman who had presented with a pulsatile mass on the right side of the

BACKGROUND Blood flowing across the vascular endothelium creates wall shear stress, dependent on velocity of flow and vessel geometry, that tends to disrupt lymphocyte-endothelial cell adhesion. OBJECTIVE The microcirculation in a murine model of acute colitis was investigated to identify structural

Pseudomelanocytic nests in the setting of lichenoid inflammation can mimic atypical melanocytic proliferations. Both melanocytic and cytokeratin immunohistochemical stains may be utilized to differentiate these entities. Unlike true melanocytic nests, pseudomelanocytic nests contain Melanoma Antigen

BACKGROUND Inflammatory myofibroblastic tumors (IMTs) are rare tumors of soft tissue recognized recently and the lung is one of common organs involved. The aim of this study is to investigate the valuable clinicopathological features for diagnosis of IMTs of the lung. METHODS The clinicopathology

We report the first case of inflammatory variant of hepatic angiomyolipoma (AML) with expression of transcription factor E3 (TFE3) protein but negativity for HMB45 and melan A in a 62-year-old female. Imaging studies revealed a tumor in the left lobe of liver, sized 5.8 cm in maximum diameter.

Inflammatory myofibroblastic tumor (IMT) is an uncommon tumor characterized by inflammatory cell infiltration and differentiated myofibroblastic spindle cells. IMT was first described in the lung and retroperitoneum. Occurrence in bone has been well described in the maxilla and occasionally in the

To evaluate the patterns of chronic interstitial and granulomatous inflammation, scars and lymphangitis carcinomatosa in radiographs of excised air-inflated lungs at autopsy, the distribution of these findings in 89 lungs was determined histologically on 441 sections sampled systematically.

A surgical case of inflammatory myofibroblastic tumor arising in the uterine corpus and exhibiting prominent myxoid change of the stroma is reported. The patient was a 63-year-old woman with a large tumor mass that filled the uterine cavity and measured 11 cm in maximal dimension. The tumor had a

Intussusceptive angiogenesis is a morphogenetic process that forms new blood vessels by the division of a single blood vessel into two lumens. Here, we show that this process of intraluminal division participates in the inflammation-induced neovascularization associated with chemically induced

OBJECTIVE Nasopharyngeal inflammatory pseudotumor (NIPT) is hard to differentiate from infiltrating nasopharyngeal carcinoma (NPC) on conventional magnetic resonance imaging (MRI). The purpose of this study is to determine whether discrepant lesion sizes estimated on T1- and fat-suppressed

"Inflammatory pseudotumors" (IPTs) embrace a heterogeneous spectrum of reactive, infective, and neoplastic entities, that are characterized by a clinical mass composed of a histologic proliferation of spindle cells in a background of inflammatory cells and collagen fibers. Although a spectrum of

OBJECTIVE Osteoarthritis (OA) is a chronic musculoskeletal disease characterized by progressive destruction of articular cartilage, OA lead to chronic pain and functional restrictions in affected joints. The present study was to investigate the role of osteopontin (OPN) in the athogenesis of OA

The vascular endothelium is a continuous layer of flat polygonal cells that are in direct contact with the blood and participate in responses to inflammation. Chrysin is a flavonoid compound extracted from plants of the genus Asteraceae with a wide range of pharmacological activities and

Fine-needle aspiration cytology has been shown to be useful in the diagnosis of lesions of the distal extremities with an accuracy of ∼70% for the specific diagnosis of tumors of the hand. Despite this accuracy, some cases may be misinterpreted as to the type of lesion present. A 34-year-old male

Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of dedifferentiated liposarcoma (DDLPS) with inflammatory myofibroblastic tumor (IMT)-like features. Methods: Five cases of DDLPS with IMT-like features were collected from the First
