Intravascular Large B Cell Lymphoma: A Rare Case Report

Diffuse Large B-Cell Lymphoma is characterized by the infiltration of small vessels by lymphoid cells. These cells are not seen in the systemic circulation. Depending on the involvement location, it may present with different clinics such as central nervous system and skin involvement. Therefore, diagnosis may delay. Diagnosis is based on pathology. Herein we present a rare patient who initially presented with cellulitis and was ultimately diagnosed with Intravascular Large B Cell Lymphoma. With this case, we aim that lymphoma infiltration should be considered in skin lesions that are difficult to diagnose.
