A 53-year-old breast cancer patient who underwent breast-conserving surgery of the right breast presented with fever, leukocytosis, C-reactive protein elevation, and redness of the right breast on postoperative day (POD) 3. The breast wound showed desquamation with painful ulcerative changes from POD 6, and fever was sustained under antibiotic administration. Wound irrigation was attempted; however, inflammatory skin damage progressed to involvement of the entire skin overlying the breast. With clinical suspicion of PPG, skin biopsy and systemic corticosteroid initiation were performed on POD 12. Wound damage progression ceased, and the systemic inflammation subsided. The patient underwent split-thickness skin grafting under intravenous corticosteroid administration, and the wound healed after 30 days. PPG is a rare clinical scenario. Early diagnosis is critical to avoid unnecessary treatment and aggravation of the surgical wound. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer owing to high heterogeneity, aggressive nature, and lack of treatment options, which has a substantial deleterious effect on patients' lives. HOXD antisense growth-associated long noncoding RNA (lncRNA) (HAGLR) plays tumor-promoting roles in many cancers. In this study, we aimed to explore the role of HAGLR in TNBC. Quantitative real-time polymerase chain reaction assays were used to examine the expression of RNAs. Functional experiments were conducted to test the biological behavior of TNBC cells. Moreover, MS2-RNA immunoprecipitation, luciferase reporter, and RNA pull-down assays were conducted to verify the binding relationship between HAGLR, microRNA-143-5p (miR-143-5p), and serine- and arginine-rich splicing factor 1 (SRSF1).
