“…However, most of these tend to be located deeper in the hypodermis, rarely involve the dermis, and are usually closer to vascular or neural bundles and tendons. Furthermore, these neurogenic benign tumors commonly appear as hypovascular (with mostly peripheral blood flow) or avascular structures . So far, no snow falling or fluid‐fluid level signs have been reported in superficial schwannomas.…”

Nodular hidradenomas are benign sweat gland-derived tumors that can produce clinical and dermatoscopic misdiagnoses. Histologically, these tumors can be classified into eccrine and apocrine subtypes. We present the sonographic characteristics of 6 cases of apocrine nodular hidradenomas, which, to our knowledge, is so far the largest series reported. A detailed sonographic analysis included layers, body location, shape, diameters, echostructure patterns, and vascularity. Two sonographic signs not previously reported in these or other common dermatologic lesions were detected: "snow falling" and "fluid-fluid level." The sonographic characteristics of apocrine nodular hidradenomas can support their earlier and more precise diagnosis.

“…The dermoscopic image is characteristic showing a central whitish-pink area surrounded by a faint brownish pigmentated network. On the ultrasound images, it appears as a hypoechoic but heterogeneous lesion in the region of the dermis, with unclear borders [ 38 ].…”

A compact handheld skin ultrasound imaging device has been developed that uses co-registered optical and ultrasound imaging to provide diagnostic information about the full skin depth. The aim of the current work is to present the preliminary clinical results of this device. Using additional photographic, dermoscopic and ultrasonic images as reference, the images from the device were assessed in terms of the detectability of the main skin layer boundaries and characteristic image features. Combined optical-ultrasonic recordings of various types of skin lesions (melanoma, basal cell carcinoma, seborrheic keratosis, dermatofibroma, naevus, dermatitis and psoriasis) were taken with the device (N = 53) and compared with images captured with a reference portable skin ultrasound imager. The investigator and two additional independent experts performed the evaluation. The detectability of skin structures was over 90% for the epidermis, the dermis and the lesions. The morphological and echogenicity information observed for the different skin lesions were found consistent with those of the reference ultrasound device and relevant ultrasound images in the literature. The presented device was able to obtain simultaneous in-vivo optical and ultrasound images of various skin lesions. This has the potential for further investigations, including the preoperative planning of skin cancer treatment.

ObjectivesA compact handheld skin ultrasound imaging device has been developed that uses co-registered optical and ultrasound imaging to provide diagnostic information about the full skin depth and lesions encountered therein. The aim of the current work is to present the first clinical results of the device. Using additional photographic, dermoscopic and ultrasonic images as reference, the images from the device are assessed in terms of the detectability of the skin layer boundaries (between the epidermis, dermis, and subcutis), and in terms of image features produced by common skin lesions.MethodsCombined optical-ultrasonic recordings of various types of common skin lesions (melanoma, basal cell carcinoma, keratosis, dermatofibroma, naevus, dermatitis, psoriasis) were taken with the device (N = 53) and compared with images from a reference portable skin ultrasound imager. The investigator and two additional independent experts evaluated and compared the images in terms of skin structure detectability and skin lesion features.ResultsSkin structure detectability was unanimously over 90 % for epidermis, dermis and lesion. Morphological and echogenicity information observed for melanoma, basal cell carcinoma, keratoses, dermatofibroma, naevi, atopic dermatitis, psoriasis were found consistent with those of the reference ultrasound device and relevant ultrasound images in the literature.ConclusionsThe presented device is able to obtain simultaneous in-vivo optical and ultrasound images of common skin lesions. This has the potential to provide relevant information in a number of settings to be investigated in the future, including preoperative planning of skin cancer treatment.
