The clinical and pathological features are described of a case of pulmonary calcinosis complicating cystic disease of the renal medulla. A histopathological study of the lung revealed calcification in the alveolar walls and in the blood vessels, predominantly in the pulmonary veins and venules. The calcified deposits were also studied by electron microscopy, and appearances suggestive of active...

Metastatic pulmonary calcification (MPC) is a rare pathological condition consisting of lung calcium salt deposits which commonly occurs in patients affected by chronic kidney disease probably for some abnormalities in calcium and phosphate metabolism. CT represents the technique of choice for detecting MPC findings including ground glass opacities and partially calcified nodules or consolidati...

Experimental metastatic calcification in the proximal convoluted tubules of rat kidney, produced by large doses of vitamin D, has been studied with a variety of techniques. These techniques include the examination of thin sections of Araldite-embedded material under the electron microscope, selected area electron diffraction, and several histochemical methods. Two types of mineral are found in ...

RATIONAL Epithelioid hemangioendothelioma (EHE) is a rare neoplasm commonly known to arise from the soft tissue, lung, and liver. EHE arising from right innominate vein (RIV) has scarcely been reported in English literature. PATIENT CONCERNS Herein, we present a rare case of EHE of RIV in a 51-year-old woman with right-lower chest pain for 4 days. Computed tomography of the chest revealed a s...

ABSTRACT Partial pulpotomy is a treatment method used to reach healthy pulp tissue by removal of the inflamed in 1-3 mm depth from caries exposed teeth. Pulpal bleeding should be controlled using bactericidal agents, such as sodium hypochlorite or chlorhexidine, and then covered with biocompatible material, MTA. MTA placed on area surrounding dentate thickness at least 1.5 resin modified glass ...

RATIONALE Matrix vesicles (MVs) are specialized structures that initiate mineral nucleation during physiological skeletogenesis. Similar vesicular structures are deposited at sites of pathological vascular calcification, and studies in vitro have shown that elevated levels of extracellular calcium (Ca) can induce mineralization of vascular smooth muscle cell (VSMC)-derived MVs. OBJECTIVES To ...

Introduction: Compared with the general population, hemodialysis patients are at increased risk of vascular calcification, which in turn is associated with an increased risk of mortality. Regarding the role of vitamin D in bone formation, regulation of calcium, phosphate and iPTH level and correlation of these variables in survival, this study was performed to evaluate the vitamin D serum level...

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare tumefactive lesion with unclear pathogenesis. It diagnosed by pathological findings typical histological features that include granular amorphous cores palisading spindle to epithelioid cells, variable fibrous stroma, foreign-body reaction giant and calcification/ossification occasionally psammoma bodies. However, its histopathology m...

Hepatic calcification is usually associated with infectious, vascular, or neoplastic processes in the liver. We report the first case of beta-thalassemia major with isolated diffuse hepatic calcification in a 23 year old woman, who had been transfusion-dependent since the age of 6 months. She was referred to our center with a chief complaint of abdominal pain. Computed tomography scan of the ab...

Bone metastases are the most common and hard-to-treat complication of BC. About 70% patients with metastatic BC have distant bone relapses during disease. always leads to death within 5-10 years, this statistic has not changed in last 2-3 decades. The work aims carry out a bibliometric analysis interrelationships BC, processes biomineralization (calcification), tissue. authors searched electron...
