Giant cutaneous ulcer in Epstein-Barr virus positive T-cell/NK-cell lymphoproliferative disorder: A case report.

Background: Epstein-Barr virus (EBV)-positive T-cell/natural killer (NK)-cell lymphoproliferative disorder is a rare but challenging condition that requires multidisciplinary teamwork, including co-management by infection medicine, radiotherapy, rehabilitation, and psychology experts, as well as wound specialist nurses.

Case summary: The patient was a 33-year-old female who presented with an erythema-like lesion on the left upper extremity that became desquamated and then blistered and eventually became a giant ulcer with exposed nerves and muscles. The left wrist had a fixed posture, and pathology tests showed cutaneous EBV-positive NK/T-cell proliferative disease. We employed a multidisciplinary collaborative treatment approach, and after 13 wound changes over 45 days, combined with radiation therapy, dietary supplementation, and psychosocial therapy, the left upper extremity wound healed.

Conclusion: Giant ulcers caused by cutaneous EBV-positive NK/T-cell proliferative disease can be treated using a multidisciplinary collaborative approach.
