“…With respect to scleroderma ulcers, inflammation and superinfection can also be assessed by US as increased vascularization is evidenced on color Doppler US [58]. Calcinosis associated with scleroderma and dermatomyositis can also be detected and evaluated by US [58,59]. Recently shear wave elastography evaluation of scleroderma patients has been confirmed to be useful for the evaluation of generalized scleroderma patients [60].…”

Dermatologic ultrasound is a recent application of ultrasound for the evaluation of healthy skin and appendages and their diseases. Although the scientific literature regarding this application is still not sufficient for evidence-based guidelines, general recommendations issued by scientific societies are necessary. The EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) steering committee for dermatologic ultrasound has developed a series of consensus position statements regarding the main fields of dermatologic ultrasound (technical requirement, normal skin and appendages, inflammatory skin diseases, tumoral skin diseases, aesthetic dermatology and practice-training requirements). This document is the foundation for future evidence-based recommendations and guidelines for dermatologic ultrasound practice.

“…Cutaneous calcifications are one of the common dermatologic entities diagnosed on ultrasonography. On sonography, calcium deposits are hyperechoic and are visible as posterior acoustic shadows, since the sound waves cannot penetrate the surface of highly dense calcium deposits 5 . Pilomatricomas, calcified epidermal cysts, and foreign body reactions should be also considered in the differential diagnosis because they can exhibit features of cutaneous calcifications on ultrasonography 6 .…”

Utilization of Ultrasonography in Dermatology: Two Case Reports of Calcinosis Cutis

et al. 2022

Development of newer generation of cost-effective ultrasonic devices in recent years has increased the use of ultrasonography in dermatology. Several lesions can be diagnosed and managed using ultrasonography. Calcinosis cutis involves the deposition of insoluble calcium salts in the cutaneous and subcutaneous tissues. On ultrasonography, it specifically presents as hyperechoic deposits with a posterior acoustic shadowing artifact due to the acoustic properties of calcium. A 62-year-old female patient presented with a solitary, skin-colored, palpable nodule on the inner side of the right lower leg. The lesion was beneath the intact skin and detectable only on palpation. However, ultrasonography demonstrated a clear delineation of the lesion, showing hyperechoic deposits with a posterior acoustic shadow (15 MHz, linear probe). Skin biopsy and curettage were performed, revealing histological features consistent with calcinosis cutis. Four weeks after the procedure, ultrasonography performed to evaluate the outcome of treatment, showed recurrence. Another 18-year-old female patient presented with a skin-colored deep-seated nodule on the left temple. On ultrasonography, linear hyperechoic deposits with a posterior acoustic shadow were visible. Skin biopsy was performed, and histopathologic features showed calcified material in the subcutaneous tissue. These two cases of calcinosis cutis highlight the diagnostic value of ultrasonography in dermatology.

“…Ultrasonography is a rapid and noninvasive technique that can provide in-vivo information for the detection and monitoring of calcium depositions. 4 On US imaging, calcium deposits are easily detected due to their hyperechoic appearance, and for producing a posterior acoustic shadow, a signal void behind calcium structures that strongly absorb ultrasonic waves. Measuring the deposits is easy, and it can be useful for the monitoring of the disease.…”

“…In calcinosis, chronic inflammatory diseases such as erythematosus systemic lupus, systemic sclerosis, dermatomyositis, or chronic panniculitis provoke different forms of calcium deposits at the extravascular level. 3,4 Calcium deposits can be observed with dermatologic US with high-resolution probes. Commonly, 15-22 mHZ probes are routinely used in the dermatological office, allowing for detection of calcium deposits of less than 1 mm.…”

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.
