Cytophagic histiocytic panniculitis with atypical lymphocytes in peripheral blood.
A 26-year-old female patient developed high fever, hepatosplenomegaly and subcutaneous nodules. Atypical lymphocytes were present in the peripheral blood. Skin biopsy revealed lobular panniculitis. Bone marrow examination showed prominent phagocytosis by benign histiocytes. The diagnosis of cytophagic histiocytic panniculitis was made, and the disease has been well controlled with oral prednisolone. This is the first report of cytophagic histiocytic panniculitis with atypical lymphocytes in the peripheral blood, which are frequently seen in virus-associated hemophagocytic syndrome. This observation suggests that underlying viral infection may be one factor in the development of cytophagic histiocytic panniculitis.
