Sinonasal calcificates

Dystrophic calcification is the accumulation of calcium salts, mainly phosphates, which can occur in any part of the body. Unlike other heterotopic calcifications, it occurs in damaged tissue in the absence of calcium metabolism disorders. The article presents a clinical case of long-term presence of a rhinolith in the nasal cavity. It has been shown that tissue damage as a result of long-term inflammation or other pathological process is the triggering mechanism of calcificates formation in the synonasal region. Not only a foreign body, but also altered own tissues as well as colonies of pathogens of fungal infection that have undergone necrosis can become the center of calcification.
