A rare cause of cytopenia in a patient with systemic lupus erythematosus: Autoimmune myelofibrosis.

Hematological abnormalities are very common in the course of systemic lupus erythematosus (SLE). Myelofibrosis is a bone marrow disorder in which there is excessive fibrous tissue formation in the bone marrow. Various benign and malignant disorders can cause or be associated with a diffuse increase in the bone marrow reticular tissue. Some diseases such as infections, neoplasms, and autoimmune diseases may also induce bone marrow fibrosis (secondary myelofibrosis). Cytopenia from autoimmune myelofibrosis (AIMF) in SLE is a rare condition. Here we present a case of AIMF associated with SLE and aim to emphasize on the other cause of cytopenia in SLE.
