Photoletter to the editor: Response of linear porokeratosis to photodynamic therapy in an 11-year-old girl. J Dermatol Case Rep. 2015 ; 9(4):118-9http://hdl.handle.net/10668/2187Journal Article;Porokeratoses are a group of different entities that belong to the skin keratinization disorders. From the histological point of view the main and common characteristic of these disorders is the presence of compact parakeratotic columns known as cornoid lamellae. All varieties should be carefully treated and followed-up because of the risk of developing malignant epithelial tumors. We report the successful response to photodynamic therapy (PDT) in a pediatric patient diagnosed with linear porokeratosis.enPathologyPorokeratosisTreatmentChildNeoplasiasFotoquimioterapiaPoroqueratosisRiesgoEnfermedades de la pielFenómenos Fisiológicos de la PielMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::Keratosis::PorokeratosisMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Diseases::NeoplasmsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Therapeutics::Phototherapy::PhotochemotherapyMedical Subject Headings::Phenomena and Processes::Mathematical Concepts::Probability::RiskMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin DiseasesMedical Subject Headings::Phenomena and Processes::Integumentary System Physiological Phenomena::Skin Physiological Phenomenaresearch article26848323open access10.3315/jdcr.2015.12201898-7249PMC4733358
