Diabetic hand syndrome, also known as diabetic cheiroarthropathy, is a disorder marked by limited joint movement and features resembling scleroderma. Scleroderma-like skin changes are frequently linked to uncontrolled diabetes, in contrast to limited scleroderma, which typically manifests with a prior history of Raynaud’s phenomenon. This underscores the fact that scleroderma-like is often underdiagnosed and can mimic both autoimmune and microvascular disorders.

In this report, we presented a case of a 58-year-old diabetic female with a 1-year history of gradual stiffening of the fingers with frequent episodes of white-blue discoloration. Physical examination revealed multiple ulcers on sausage-shaped fingers, erythematous thick plaques topped with crust on the palms with associated induration, thickening, and a positive prayer sign. Biopsy of the palms and digits shows thickened collagen bundles in the superficial to deep dermis. Alcian blue was positive. Blood chemistry showed elevated glycosylated hemoglobin and fasting glucose. Immunoassays were negative for ANA, RF, anti-dsDNA, anti-RNP, anti-SM, anti-SSA, SCL70, and anti-CENP. Treatment with potent corticosteroid twice daily was started concurrently with the initiation of insulin by the endocrinologist.

Our case highlights the importance of early recognition of scleroderma-like cutaneous manifestations, whose close relationship to diabetes mellitus affects its overall morbidity. Prompt screening for endocrinopathy will help in early treatment initiation and prevent further complications.
