—Positioning the probe (light grey rectangle; red in the online version) over the dorsal surface of the hand/fingers (A). Dermal sclerosis (white asterisks) associated with dilatation of the superficial dorsal veins (light grey arrowheads; blue in the online version) and striped edema of the subcutaneous tissue (SUBC) is clearly visualized (B, C). In the chronic phase, fibrotic tissue (light grey arrowheads; yellow in the online version) wrapping the superficial veins (i.e., perivascular fibrosis) can be identified as well (D). PP: proximal phalanx, MC: metacarpal bone.
