# Invasion of Diffuse Large B-Cell Lymphoma to Right Axillary Arterial Graft

## TL;DR

A rare case of diffuse large B-cell lymphoma invading an arterial graft in a patient with a history of aortic surgery is reported.

## Contribution

This case highlights the rarity and diagnostic importance of DLBCL originating around a surgical graft.

## Key findings

- DLBCL was diagnosed around a right axillary arterial graft in a 76-year-old male.
- The patient's condition precluded chemotherapy and he passed away within 3 months.
- Such lymphoma origin around grafts is extremely rare but important for differential diagnosis.

## Abstract

A 76-year-old male patient, who had undergone right axillary artery bypass and arch replacement surgery for retrograde type A aortic dissection after thoracic endovascular aortic repair 2 years ago, was referred to our department with complaints of swelling and pain in the right subclavian region. A computed tomography scan suspected an abscess around the bypass graft; however, the culture was negative. Pathological examination indicated a diffuse large B-cell lymphoma (DLBCL) diagnosis. Chemotherapy was not indicated due to the patient’s condition, and he passed away after 3 months. DLBCL originating around a graft is extremely rare but crucial for differential diagnosis.
