Both medial and lateral wounds were assessed qualitatively and quantitatively 4 weeks prior to initial treatment (Figure 1(b)-(e)). A total of three treatment sessions were performed over 10 weeks and a final observation was conducted at week 17 (Figure 1(a)). When the patient arrived for the first treatment, both the medial (Figure 1(b) and (c)) and lateral (Figure 1(d)) wounds were non-healed despite successful RFA. During the first treatment (Figure 1(b) and (d) "week 0"), two 2 mL vials of Dermacyte  Liquid were diluted 1:1 (8 mL total volume) and injected around the wound bed periphery of the lateral VLU and one 2 mL vial (4 mL total diluted solution) was used for the medial VLU. Interestingly, closure of the medial wound was observed after 4 weeks and its treatment was discontinued (Figure 1(b) and (c)). The lateral wound also showed qualitative (Figure 1(d)) and quantitative improvement during the 4-week time (Figure 1(e)). Additional reduction in wound size was observed at weeks 8 and 10 (Figure 1(d) and (e)). At the 17-week follow-up, the patient demonstrated almost complete wound closure with significant areas of re-keratinization (Figure 1(f)).
