Care and Treatment for an Antiphospholipid Syndrome-Related Lower Limb Skin Ulcer Unhealed for 7 Years: A Case Report

Antiphospholipid syndrome (APS) is a group of rare autoimmune diseases caused by antiphospholipid antibodies that is mainly associated with arterial or venous thrombosis and/or complications during pregnancy. Skin lesions occur in approximately 30% of APS patients as initial manifestations. However, previous studies have primarily focused on the treatment of APS rather than the management of skin lesions. Here, the authors report a case of an APS-related lower limb skin ulcer that had remained unhealed for more than 7 years. The difficulties in this case were the diagnosis of APS, the risk of bleeding during debridement, wound infection, biofilm formation, reduced venous return from the lower limbs, and compliance with compression therapy and follow-up. A three-step wound care regimen based on a multidisciplinary team approach resulted in effective control of APS and healing of the ulcer to the lower leg in 95 days. Over two follow-ups, there was no recurrence of the ulcer.
