RT Journal Article T1 Histological Changes Related to Symptomatic Improvement of Spontaneous Keloids Treated with a Low-Dosage Regimen of UVA-1 Phototherapy. A1 Cuenca-Barrales, Carlos A1 Aneiros-Fernández, José A1 Pérez-López, Israel A1 Rodríguez-Pérez, Julia A1 Ruiz-Villaverde, Ricardo A1 Espelt-Otero, Jorge Luis K1 clinical K1 keloid K1 pathology K1 phototherapy AB Keloids are a difficult-to-treat disease characterized by an imbalance in mechanisms of tissue reparation. We present the case of a middle-aged woman with spontaneous keloids which histologically and clinically improved after UVA-1 phototherapy treatment. There are few reported cases of keloids treated with high doses of UVA-1 phototherapy. We used a low-dosage regimen with a good response in only one cycle, which could diminish the risk of skin cancer development.
