Abstract:
We report a rare case of a ruptured deep femoral artery aneurysm caused by direct infiltration of diffuse large B-cell lymphoma (DLBCL). An 82-year-old man presented with acute left thigh pain and a rapidly formed aneurysm revealed by imaging. Open aneurysmectomy and bypass grafting were performed. Histopathology demonstrated destruction of the elastic laminae and media with diffuse infiltration of atypical lymphoid cells, thus confirming DLBCL. The patient received the best supportive care. Further arterial ruptures developed, and the patient died 8 months after surgery. Malignancy should be considered in the differential diagnosis of rapidly progressive, peripheral aneurysms.
