Wound care of Sweet syndrome in a patient with anaplastic lymphoma kinase-positive anaplastic large cell lymphoma: a case report.

Sweet syndrome (SS), which is characterised by fever and erythematous tender skin lesions, has been shown to be associated with lymphoma. However, there are limited reported experiences on the wound care of SS in patients with lymphoma. This case report presents the wound care of SS in a patient with anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALK+ALCL). A 42-year-old male was referred to the The First Affiliated Hospital of Guangzhou University of Chinese Medicine Hospital with redness and pain in the left shoulder and abdomen following chemotherapy for ALK+ALCL in early 2021. Physical examination found lesions in the abdomen and shoulder. The lesions were ruptured on day 5 and found to be composed of necrotic tissues. After debridement, the wounds were successively treated with silver ion antibacterial dressing, Mepilex Border Lite (Mölnlycke Health Care, Sweden), silver sulfadiazine gauze, Shengji ointment (a traditional Chinese therapy), UrgoTül (Urgo Medical, France), and fire needling therapy (another traditional Chinese therapy). At three months later, the wound in the abdomen was healed, but the shoulder wound was still unhealed. Based on the physiological manifestations and current treatment process, the patient was diagnosed with SS after multidisciplinary consultation. Prednisone tablets were then administered and the shoulder wound completely healed after two months.
