[Papular mucinosis. Associated dermatologic and dysimmune aspects]
Abstract:
Papular mucinosis (PM) is an overload disease mostly made of proteoglycans, essentially cutaneous and accompanied with a monoclonal gammapathy. In addition to the cutaneous lesions, vascular and neurological manifestations may be responsible for severe complications. The gammapathy, most often benign, does not seem always correlated with the skin involvement. We report the case of a patient with mucinosis associated with a rheumatoid polyarthritis, then with a systemic necrotizing angiitis. A review of the literature has enabled us to notice the frequency with which PM is accompanied with dysimmune diseases, especially lupus.
Insights
Papular mucinosis (PM) is a proteoglycan overload disease often linked to monoclonal gammopathy. This case highlights PM
Area of Science:
- Dermatology
- Rheumatology
- Neurology
Background:
- Papular mucinosis (PM) is characterized by proteoglycan accumulation, primarily affecting the skin.
- It is frequently associated with monoclonal gammopathy, which may not always correlate with cutaneous manifestations.
Observation:
- This report details a patient with papular mucinosis who developed rheumatoid polyarthritis and subsequently systemic necrotizing angiitis.
- The patient presented with cutaneous lesions, indicative of PM.
Findings:
- The literature review revealed a significant association between papular mucinosis and dysimmune diseases, particularly lupus.
- The presented case underscores the potential for severe systemic complications, including vasculitis, in patients with PM.
Implications:
- Papular mucinosis requires comprehensive evaluation due to potential systemic and autoimmune associations.
- Early recognition of associated dysimmune conditions and vasculitis is crucial for managing severe complications.
