    Progressive systemic sclerosis can mimic vinyl chloride disease early on. Characteristic visceral involvement is key to distinguishing systemic sclerosis from vinyl chloride-induced pseudoscleroderma.

    Area of Science:

    • Rheumatology and Occupational Medicine

    Background:

    • Distinguishing progressive systemic sclerosis (PSS) from vinyl chloride disease (VCD) can be challenging, particularly in early stages before significant internal organ involvement.
    • Vinyl chloride exposure is known to cause a scleroderma-like illness, termed vinyl chloride disease.

    Observation:

    • A 50-year-old male, occupationally exposed to polyvinyl chloride, developed classic scleroderma.
    • His early disease presentation included features overlapping with VCD, such as acroosteolysis, sclerodactyly, hypergammaglobulinemia, and circulating immune complexes.

    Findings:

    • The cardinal feature differentiating his condition was the presence of characteristic visceral involvement, typical of PSS.
    • This contrasts with the pseudoscleroderma observed in VCD, which typically lacks significant internal organ pathology.

    Implications:

    • Early recognition of overlapping symptoms is crucial for accurate diagnosis.
    • Identifying characteristic visceral organ involvement is essential for differentiating PSS from VCD, guiding appropriate patient management and prognosis.
