Resumen:
Objectives Calcium depositions are frequent in multiple inflammatory dermatosis, they can be explored by ultrasound (US) but the patterns of these depositions have not yet been described. The aim of this study is to describe different patterns of calcium deposition in inflammatory dermatoses. Methods The clinical and US data of 58 patients from 7 different centers with inflammatory dermatosis showing ultrasonography-detected calcium depositions was retrospectively reviewed. Results Dystrophic calcinosis represented 86.2%, calciphylaxis 8.6%, and metastatic calcinosis 5.2%. Three different sonographic patterns of calcium deposition were found: 1) thin hyperechoic bands, parallel to the surface of the epidermis, generating a strong and wide posterior acoustic shadow; 2) hyperechoic spots or lumps with a narrow acoustic shadow; and 3) a linear hyperechoic band parallel to the walls of a blood vessel with also a narrow acoustic shadow. The predominant pattern in metastatic calcifications was type 1, in dystrophic calcifications type 2, and in calciphylaxis type 3. In dystrophic calcinosis, cutis deposits were longer and wider than in calciphylaxis (P < .05). Conclusion New data on inflammatory dermatoses with calcium deposition may be useful for the diagnosis and monitoring of calcium deposits and could avoid the performance of more invasive tests, such as a skin biopsy.
