Idiopathic Thrombocytopenia Purpura Masking Hodgkin Disease: A Paraneoplastic Syndrome or Simply a Mere Association?

摘要

We report a 74-year-old female who presented to the emergency department complaining of bruising and stroke-like symptoms. She underwent a negative stroke work-up but was found to have profoundly low platelets and splenomegaly on examination. An abdominal CT scan was ordered, showing pelvic lymphadenopathy. Lymphoma was suspected. However, subsequent bone marrow and lymph node biopsies showed no evidence of this. She was treated for immune thrombocytopenia purpura (ITP) to no avail while a lymphoma work-up continued. Months later, a third and final lymph node biopsy yielded evidence of Hodgkin disease (HD) and she began treatment shortly thereafter. She is currently undergoing standard treatment for this malignancy and her platelet counts have normalized. The case not only outlines the importance of the physician's gestalt in arriving at the proper diagnosis, but it also posits the thought that perhaps ITP should be considered a paraneoplastic syndrome of HD.
