Role of Skin Biopsies in the Diagnosis of Hemophagocytic Lymphohistiocytosis

Abstract: This is a report of a 15-year-old female who presented with a skin eruption and clinical features consistent with severe sepsis and septic shock. A diagnosis of acquired hemophagocytic lymphohistiocytosis (HLH) was made and confirmed by bone marrow analysis. Skin biopsy showed hemophagocytosis and CD163-positive staining of macrophages. We briefly review the clinical, histologic, and laboratory findings of hemophagocytic lymphohistiocytosis in addition to the potential role of skin biopsies in this condition.
