Hemophagocytic syndrome secondary to adult-onset Still's disease but very similar to lymphoma.

Hemophagocytic syndrome (HPS) is a clinicopathologic entity characterized by increased proliferation and activation of benign macrophages with hemophagocytosis throughout the reticuloendothelial system. HPS may be primary, or secondary to malignancy, infections, auto-immune diseases and pharmacotherapy. In patients with adult-onset Still's disease (AOSD), HPS is a rare but life-threatening complication. Herein, we described a female patient with HPS secondary to AOSD. During the therapy, giant gastric ulcer similar to lymphoma developed after treatment with corticosteroid and nonsteroidal anti-inflammatory drugs.
