Core Tip
Core Tip: Diabetic foot ulcers (DFUs), although common in diabetes, rarely coexist with connective tissue diseases, particularly overlap syndromes. We describe a unique case involving DFUs with overlap syndrome [systemic sclerosis (SSc) and anti-synthetase syndrome (ASS)]. Literature analysis revealed three key patterns in SSc-related foot ulcers: Low incidence, predominant toe involvement, and rare diabetes comorbidity. No ASS-related foot ulcer cases have been reported. The prognosis of SSc-related foot ulcers is generally favorable, with standard DFU therapies (notably autologous platelet-rich gel) showing efficacy. Bosentan and calcium channel blockers may have therapeutic and preventive effects on SSc-related foot ulcers.
