Abstract

OBJECTIVE
To describe the clinical and ultrasonographic (US) findings in patients with scleredema adultorum of Buschke, who presented with sclerotic skin on their posterior neck.
MATERIALS AND METHODS
After obtaining IRB approval, eight patients with scleredema adultorum of Buschke were enrolled. They underwent US examination of their posterior neck. The diagnoses were confirmed pathologically. The clinical history and US images were evaluated retrospectively. Dermal thickness was compared between the patient group and the age- and sex-matched control group.
RESULTS
The patients included seven males and one female with a mean age of 51.5 years. All patients presented with thickening of the skin and/or a palpable mass on the posterior neck. Five (62.5%) of the eight patients showed erythematous discoloration. Six patients (75.0%) had a history of diabetes. The Hemoglobin A1c level was found to be increased in all patients. US images did not show any evidence of a soft tissue mass or infection. The mean dermal thickness in patients (7.01 ± 1.95 mm) was significantly greater than that in the control group (3.08 ± 0.87 mm) (p = 0.001). Multiple strong echogenic spots in the dermis were seen in all patients. Seven patients (87.5%) showed posterior shadowing in the lower dermis.
CONCLUSION
When a patient with a history of diabetes presents with a palpable mass or erythematous discoloration of the posterior neck and US shows the following imaging features: 1) no evidence of a soft tissue mass or infection, 2) thickening of the dermis, 3) multiple strong echogenic spots and/or posterior shadowing in the dermis, scleredema adultorum of Buschke should be considered in the differential diagnosis.

Ultrasonographic image showing thickened dermis and marked posterior acoustic shadowing in lower dermis area. There is no vascularity on color Doppler imaging. B.
