The differential diagnosis for chronic cutaneous ulcers is wide. Once the common causes have been excluded, infrequent ones, including drugs, should be considered. We report the case of a 67 year old woman with multiple ulcers not responding to conventional treatment. Multiple investigations including laboratory testing, skin biopsies and tissue cultures were negative. A few cases of leflunomide-induced cutaneous ulcers are reported in the literature. Our patient was on this drug for 12 years. Discontinuation of leflunomide led to ulcers resolution. This is the longest reported time interval between leflunomide initiation and ulceration onset.

Phosphodiesterase-4 (PDE4) is involved in the synthesis of inflammatory cytokines that mediate several chronic inflammatory disorders, including psoriasis and atopic dermatitis. In recent years, the therapeutic armamentarium in dermatology has expanded with the introduction of PDE4 inhibitors, both in oral and topical formulations. PDE4 inhibitors have gained increasing interest due to their remarkable safety record and ease of prescription, as evidenced by the recent influx of literature detailing its off-label uses.

: Larval therapy (LT), an intervention using live fly larvae to remove necrotic tissue and promote healing, has regained attention in order to address the growing need for chronic wound management. LT was approved by the Food and Drug Administration (FDA) in 2004 to treat difficult-to-heal wounds; however, LT remains an underutilized therapy. To evaluate efficacy of LT in a systematic review and meta-analysis of wound outcomes from randomized controlled trials (RCTs).

In the context of palliative care, the aim is to alleviate suffering and improve quality of life, with particular attention to PUs, which have a significant impact on quality of life and survival. This study examines the relationship between perilesional skin condition and survival in terminally ill patients with pressure ulcers (PUs). A descriptive and observational study was conducted in two hospitals in Valencia with a sample of 100 terminally ill patients.

: According to the International Working Group on Diabetic Foot (IWGDF) risk classification, the estimated risk of developing a diabetic foot ulcer (DFU) is much higher in patients with a history of DFUs (Grade 3) compared to those with a peripheral neuropathy but without a history of DFUs (Grades 1 and 2). It has been suggested that microcirculation impairment is involved in DFU genesis and could be taken into account to refine the existing risk classification. The aim of this study was to evaluate microcirculation parameters in patients with diabetes according to their estimated DFU risk.

Sickle cell disease (SCD) presents complex clinical manifestations influenced by genetic, social, environmental, and healthcare access factors as well as socioeconomic status. In this context, sickle cell leg ulcers (SLUs) are a debilitating complication of SCD. We aimed to describe sociodemographic data and evaluate the quality of life (QoL) of SCD patients with and without SLUs.
