Systemic involvement in scleredema of Buschke associated with IgG-kappa paraproteinaemia.

Abstract

Scleredema is a rare primary cutaneous mucinosis. Systemic involvement is uncommon and histological confirmation is often lacking. We report a case of a 60-year-old man with scleredema and evidence of mucin deposition on biopsies from multiple extracutaneous sites. The bone marrow, nerve, hepatic and salivary gland involvement seen on histology in our patient has not, to our knowledge, been previously reported in this condition.
