Gelatinous transformation of bone marrow with pancytopenia in an emaciated patient with systemic lupus erythematosus

We report on gelatinoustransformation of the bone marrowin a 42-year-old male patient with systemic lupus erythematosus(SLE). Gelatinoustransformation of the bone marrowin SLE is rare. This condition is composed of hypocellularity with deposition of hyaluronic acidin the bone marrowand is known to be associated with malnutritiondue to cachexiaand anorexianervosa. In this patient we consider that malnutritioncaused gelatinoustransformation which worsened pancytopeniadue to SLE. Pancytopeniaimproved after methylprednisolonepulse therapy and nutrition therapy.
