KEY FACTS


Terminology







image
Clinical photograph of a young man with a protruding mass image with bluish discoloration on the dorsum of the 2nd toe is shown. The mass had been growing slowly for 3 years.


image
Transverse US of the same mass shows a well-defined roundish mass image within the subcutaneous tissues in contact with the dermis. The mass contacts the extensor digitorum tendon image over the proximal phalanx image. The tendon moved freely on dynamic examination.


image
Transverse color Doppler US of the same tumor shows marked central and peripheral hyperemia image. This level of hyperemia is unusually high for dermatofibrosarcoma protuberans (DFSP).


image
Coronal intermediate-weighted MR of the same lesion shows a well-defined dermal/subcutaneous mass image in contact with but separate from the extensor tendon image overlying the proximal phalanx. Histology revealed DFSP.
