[A Case of Recurrent Malignant Lymphoma Occurring at an Implanted Central Venous Port]

A man in his 40s presented with fever and nasal congestion. NK-T cell lymphoma was pathologically diagnosed. A central venous(CV)port was implanted via a right subclavian approach. Four months later, redness and swelling were observed around the implanted CV port. Initially, an infection of the CV port was suspected, and the CV port was removed. Regardless of the removal of the port, the wound healing was refractory, and an ulcer formed. Surgical biopsy from the ulcer showed skin infiltration of NK-T cell lymphoma. In cases ofref ractory wound healing around an implanted CV port in patients with lymphoma, lymphoma recurrence and port infection should be considered.
