From open wound treatment to primary soft-tissue non-Hodgkin lymphoma diagnosis; a challenging case report.

Abstract

Primary soft-tissue extranodal lymphomas are rare clinical entities. By their natures, they can cause significant swelling around the affected extremities, and they can be easily misdiagnosed with other conditions like sarcomas. We share an unfortunate experience of a young male patient who was admitted to another clinic with complaints of a large mass in his right thigh, the patient has been diagnosed with anaplastic pleomorphic sarcoma, and he was scheduled for surgery. The patient refused the operation and was admitted to our emergency clinic with an open wound on his right thigh. Successful open wound management was achieved with antibiotic therapy, tissue debridement, larvae therapy, and Vacuum-assisted closure. Meanwhile, the pathologic re-examination revealed diffuse large B-cell lymphoma. After an uneventful follow-up, the patient was referred to the hematology clinic. This case highlights the importance of considering alternative diagnoses before making surgical intervention decisions that may result in unpleasing consequences.
