An LE cell is a neutrophil or macrophage that has phagocytized (engulfed) the denatured nuclear material of another cell.[1] The denatured material is an absorbed hematoxylin body (also called an LE body).[2]

They are a characteristic of lupus erythematosus,[3] but also found in similar connective tissue disorders.

The LE cell was discovered in bone marrow in 1948 by Malcolm McCallum Hargraves (1903–1982), a Physician and Practicing Histologist at the Mayo Clinic et al.[4]

Classically, the LE cell is analyzed microscopically, but it is also possible to investigate this phenomenon by flow cytometry.[5]
