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...

Trichoadenoma is a rare skin tumor first described by Nikolowski. There are variable clinical features and tumors have been diagnosed as cysts, basal cell epithelioma and seborrheic keratosis. The microscopic feature mainly consists of numerous cysts surrounded by eosinophilic cells. Trichoadenoma is benign and treatment is by simple excision. We report a case of trichoadenoma on the nose...
