case_images: On clinical observation, the nodule was covered by a structurally normal mucosa both on dorsal and ventral surfaces of the interested hemitongue, but with a slightly hyperemic red-blue color (Figure 1(a)). One month after the first application, the lesion was reduced in volume but appeared to be stable in color (Figure 1(b)); therefore, it was decided to perform another laser application. The residual lesion size was 15.5 x 10.1 x 12 mm (Figure 1(c)). At 24- and 36-month follow-up, the obtained outcomes remained clinically successful (Figure 1(d)). At 40 months, the malformation size was reduced and clinically not appreciable (Figures 1(e) and 2(d)).

case_images: The major septa were intensely prelude with mainly arterior signals, supplied by deep branches of lingual arteries (Figure 2(a)). At 12-month follow-up, a new ultrasound exam was performed: it showed a discreet volumetric reduction, with a microvacuolar structure with clear polycyclic edges, some fibrocalcific striae, and 2.2 mm calcifications of posterior profile (Figure 2(b)). At 24-month imaging follow-up, the ultrasound exam showed a lesion with clear polycyclic edge with finely evident cleavage plane on contiguous uninjured tissue, not reflective structure with thin striae of fibrosis and vacuolar areoles, and 2 mm calcification of intense reflectivity (Figure 2(c)).
