Weber-Christian disease with benign cytophagic histiocytes in the skin lesion.

We describe an 8 year old female with Weber-Christian disease who manifested erythema on her legs and an intermittent high fever. A wedge skin biopsy revealed lobular panniculitis and bean-bag cells, which were characteristic to cytophagic histiocytic panniculitis (CHP). However, she showed no evidence of liver dysfunction, hyperlipidemia, or coagulation disorders usually seen in CHP. Moreover, she responded well to oral corticosteroids therapy with resultant advanced subcutaneous fat atrophy.
