A Case of Hairy Cell Leukemia Diagnosed by Leukocyoclastic Vasculitis Symptoms

Abstract
Hairy cell leukemia (HCL) is a rare chronic lymphoproliferative disease. LSV is characterized by inflammation of small vessels. Its association is rare in the literature and HCL can be seen in LSV etiology, although the relationship between the 2 diseases is far from clear. Here, we aimed to present a case with constitutional symptoms, palpable purpuric lesions on the body and diagnosed as HCL from bone marrow biopsy.
