Background: Though rarely reported, mucin deposition may be observed in scleroderma.
Objective: To verify the frequency of significant amounts of mucin in the biopsy specimens.
Methods: Biopsies from 20 patients with scleroderma were reviewed and stained to verify the presence of mucin.
Results: Mucin deposits were found in all of the 20 specimens.
Conclusion: Mucin deposition is probably a constant feature in both morphea and systemic scleroderma. Its relevance in differential diagnosis between scleredema and scleroderma is debatable.
