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.
结节病是一种多器官疾病，其特征是形成非干酪样肉芽肿，可能伴有皮肤受累。当临床表现为深部真皮或皮下结节时，可通过超声检查来探索皮肤结节病（CS）。我们回顾了 14 名 CS 患者（86%为女性；平均年龄 55 岁）的超声特征。超声检查显示真皮或皮下低回声区，邻近皮下组织回声增强和血流增加。在 42.9%的病例中，检测到提示间隔受累的皮下组织鹅卵石样模式。这些超声特征可以支持 CS 皮肤和皮下异常的检测及其早期诊断。
