Calcifying odontogenic cyst is a developmental odontogenic cyst first described by Gorlin in 1962. It is considered as an extremely rare condition and shows extensive diversity in its clinicopathological appearances and biologic behavior. In this report a rare case of calcifying odontogenic cyst with ameloblastic proliferation (an extremely rare histologic variant) with one year follow – up is ...

The calcifying odontogenic cyst represents a heterogeneous group of lesions that exhibits a variety of clinicopathologic and behavioral features. Therefore, a proper categorization of the cases is needed for better understanding of each variant. Ameloblastoma is one of the well-known odontogenic tumors that could be associated with calcifying odontogenic cyst. Very few cases of ameloblastomatou...

INTRODUCTION AND OBJECTIVES Calcifying nanoparticles, also known as "nanobacteria," are very small bacteria-like structures (0.1-0.5 μm) with the ability to facilitate the precipitation and growth of calcium phosphate in pathological conditions and have been associated with aortic valve calcification. The status of nanobacteria is controversial; some have proposed that they are a new class of l...

BACKGROUND The purpose of this study was to examine the possible contribution of calcifying nanoparticles to the pathogenesis of placental calcification. METHODS Calcified placental tissues and distal tissue samples were collected from 36 confirmed placental calcification cases. In addition, 20 normal placental tissue samples were obtained as a control group. All the tissue samples were cultu...

BACKGROUND Calcification of the medial collateral ligament (MCL) of the knee is a very rare disease. We report on a case of a patient with a calcifying lesion within the MCL and simultaneous calcifying tendinitis of the rotator cuff in both shoulders. CASE PRESENTATION Calcification of the MCL was diagnosed both via x-ray and magnetic resonance imaging (MRI) and was successfully treated surgi...

Calcifying extracellular vesicles (EVs) released from cells within atherosclerotic plaques have received increased attention for their role in mediating vascular calcification, a major predictor of cardiovascular morbidity and mortality. However, little is known about the difference between this pathologic vesicle population and other EVs that contribute to physiological cellular processes. One...

Temperate marine rocky habitats may be alternatively characterized by well vegetated macroalgal assemblages or barren grounds, as a consequence of direct and indirect human impacts (e.g. overfishing) and grazing pressure by herbivorous organisms. In future scenarios of ocean acidification, calcifying organisms are expected to be less competitive: among these two key elements of the rocky subtid...

Calcifying aponeurotic fibroma is a rare soft tissue tumor that typically occurs in the distal extremities of children and adolescents. Because a calcifying aponeurotic fibroma is an ill-defined mass and has a tendency to infiltrate the surrounding tissue, local recurrence rates are 50%. We report a case of calcifying aponeurotic fibroma occurring in the elbow region, an uncommon site. The pati...

A generalized physicochemical model of the response of marine organisms’ calcifying fluids to CO2-induced ocean acidification is proposed. The model is based upon the hypothesis that some marine calcifiers induce calcification by elevating pH, and thus XA, of their calcifying fluid by removing protons (H ). The model is explored through two end-member scenarios: one in which a fixed number of H...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...
