Summary
This study reports a rare case of nodular scleroderma in a patient with progressive systemic sclerosis (PSS). Exposure to silica in an abrasive agent was suspected as a contributing factor.
Area of Science:
- Dermatology
- Occupational Medicine
- Rheumatology
Background:
- Progressive systemic sclerosis (PSS) is a chronic autoimmune disease characterized by hardening and tightening of the skin.
- High serum immunoglobulin E (IgE) levels can be associated with autoimmune conditions.
- Occupational exposures are increasingly recognized as potential triggers or exacerbating factors in systemic diseases.
Observation:
- A patient with PSS and elevated serum IgE presented with multiple papules on non-sclerotic skin.
- Histopathological examination of the papules confirmed features consistent with scleroderma.
- The patient had a history of prolonged occupational exposure to an abrasive agent containing aluminum, chromium dioxide, and silica.
Findings:
- This case presents nodular scleroderma occurring within the context of PSS.
- A potential association between occupational exposure to silica and the development of nodular scleroderma was observed.
- This represents the first reported instance of nodular scleroderma in PSS linked to chemical agents.
Implications:
- Highlights the potential role of occupational silica exposure in the pathogenesis of scleroderma.
- Suggests the need for thorough occupational history assessment in patients with PSS and unusual skin manifestations.
- Underscores the importance of considering environmental and chemical exposures in autoimmune and fibrotic diseases.
