Pearls and pitfalls: Autoimmune lymphoproliferative syndrome and autoimmune lymphoproliferative syndrome-like disease

A case of autoimmune lymphoproliferative syndrome (ALPS) was presented, followed by a discussion of the clinical characteristics, pathophysiology, diagnosis, and management of this disease. Clinical pearls and pitfalls are emphasized for the use of the practicing allergist and the fellow in-training. The diagnosis of ALPS was guided by published criteria. A careful history and workup were needed to exclude other possible etiologies for the patient's symptoms and physical findings. ALPS often carries significant morbidity and is best managed through a multidisciplinary approach.
