Characteristic Power Doppler Sonographic Imaging of Nodular Fasciitis from a Dermatological Perspective: Another Case and Review of Three Cases

Abstract

To clarify the characteristic ultrasonographic findings of nodular fasciitis (NF) will help to avoid unnecessary operation. The availability of high-resolution ultrasonography (US) has enabled the discrepancies of imaging features between intradermal and subcutaneous cases, furthermore, studies of NF on power Doppler US have not been bibliographically reported. We have reported one intradermal and two subcutaneous types of NF and reviewed their characteristic imaging features on US from a dermatological viewpoint. All nodules clinically represented rapid growing and self-limited and showed the proliferative findings of the margin on both US and pathology. From a dermatologic perspective, no significant differences of gray-scale US between two types were found, but blood-flow signal on power Doppler US was more detectable in intradermal type than subcutaneous one. These findings of US may be a diagnostic tool for NF.

Usefulness of Comprehensive High - Resolution Ultrasound Imaging in Dermatologic Field: Epidermal Cyst

“…We usually perform US examinations for dermatologic diseases with a high-resolution, broad-band (5MHz-18MHz) linear transducer (Nobulus Hitachi, Ltd. Tokyo, Japan). Until now, we have reported some studies in relation to the skin and subcutaneous disease [13][14][15][16][17]. Epidermal cyst is considered as level 1 content of the training program in dermatologic ultrasound by the international working group, called DERMUS [2].…”
