Thrombocytopenia and Deep Vein Thrombosis on the Top of an Iceberg

Systemic Lupus Erythematous (SLE) is a chronic autoimmune disorder with a relapsingremitting course. Besides, SLE most commonly occurs in child-bearing-age women. Due to protean manifestations, the diagnosis may be challenging; however, a high index of suspicion, i.e. achieved by experience and perceptivity is the key to a correct decision. Here, we present an SLE patient; her initial symptoms resembled a malignant process, but important elements guided us to the underlying autoimmune process. A 34-year-old woman presented with a uterine mass, deep vein thrombosis, and significant thrombocytopenia. Our first impression was malignant processes; however, considering her age with thrombosis and thrombocytopenia as the key components of her presentation, we suspected antiphospholipid syndrome and SLE. Her abdominal mass was a benign leiomyoma. We treated her with glucocorticoids and anticoagulants. Accordingly, after improving cytopenia, we discharged her and the follow-up examination result was satisfactory.
