Diffuse cutaneous Systemic Sclerosis (dsSSc) is an uncommon subtype of Scleroderma or Systemic Sclerosis (SSc), a multisystemic autoimmune disease. Philippine reports remain limited, hence there is a need to review this condition to accurately diagnose and manage Filipino patients. We present the case of a 52-year old Filipino female with a one-year history of pruritus and generalized skin thickening presenting as multiple, well-defined, hyperpigmented patches and plaques. She also presented with systemic symptoms like fever, dysphagia, and finger tenderness, swelling, numbness, and color changes upon exposure to extreme temperatures known as Raynaud’s Phenomenon. Clinical findings, alongside dermoscopic, histopathologic, nail capillaroscopy, and diagnostic data, confirmed dsSSc diagnosis with complications like Barrett’s Esophagus and Interstitial Lung Disease. Treatment options include corticosteroids, emollients, immunosuppressants, biologics, and phototherapy. Multidisciplinary teams are essential to address systemic complications.
