“…The subcutaneous form of CS seems to be frequently associated with systemic disease, particularly with bilateral hilar adenopathies 4 . To date, the ultrasound (US) features of CS have only been reported in single‐case reports or very‐short series and mainly focused on the subcutaneous involvement 5–10 . Therefore, the objective of this study was to assess the ultrasound features of CS.…”

Sarcoidosis is a multiorgan disease characterized by the formation of noncaseating granulomas and possible skin involvement. Cutaneous sarcoidosis (CS) can be explored by ultrasonography when deep dermal or subcutaneous nodules are the clinical presentation. We reviewed the ultrasound characteristics of 14 patients (86% female; mean age, 55 years) with CS. Ultrasonography revealed dermal or subcutaneous hypoechoic areas with increased echogenicity and hypervascularity of the neighboring subcutaneous tissue. In 42.9% of cases a cobblestone pattern of the subcutaneous tissue suggestive of septal involvement was detected. These US features can support the detection of dermal and subcutaneous abnormalities in CS and its early diagnosis.

Ultrasound imaging has become the preferred method for early detection of superficial organ lesions due to its non-invasive, economical, convenient, and radiation-free features. First, in the superficial organ ultrasound image analysis module based on local features, using Dense Sift as the local feature descriptor, the similarity sequence of the local features of the input image and the images in the sample library is calculated by the BOW algorithm and sorted in descending order of similarity. Secondly, using the wavelet transform’s local feature information representation capabilities in the time and frequency domains, the wavelet transform is performed on the small and identical feature information contained in the image to remove redundant information in each feature map to obtain a salient part of the image’s local features. Finally, through the analysis of elastic ultrasound images, a quantitative index that can be used to evaluate ultrasound images of superficial organs is proposed, which has higher accuracy and reliability than the current clinical methods for evaluating ultrasound images of superficial organs. By analyzing the features of superficial organ ultrasound images, it is proposed that the overall features of superficial organ ultrasound images are more conducive to distinguishing benign and malignant lesions than local features. Based on the initial localization of the lesion, the global features of the superficial organ ultrasound image were combined with the local features of the B-ultrasound image, and the method of combining global features with local features was used to classify and achieved good results.
