Abstract

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.
