Erosive pustular dermatosis of the scalp: causes and treatments.

Int J Dermatol 2021 Jan 9;60(1):25-32. Epub 2020 Jun 9.

Rutgers Robert Wood Johnson Medical School, New Brunswick, NJ, USA.

Erosive pustular dermatosis of the scalp is a rare condition which primarily affects older women after local trauma and has historically been treated with topical steroids. As it is a rare entity and resembles other dermatologic conditions, it may easily be misdiagnosed. Identifying the causes and evaluating the efficacy of treatments of erosive pustular dermatosis of the scalp (EPDS) is of great importance to both avoid misdiagnosis and ensure optimal treatment of this rare condition.

Department of Dermatology, State University of New York, Downstate Health Sciences University, 450 Clarkson Ave, Box 46, Brooklyn, NY, USA.

Photodynamic therapy (PDT) is a well-established, non-invasive treatment modality that has shown desirable effects such as improvement of fine lines, dyspigmentation, and other signs of photodamage. Many patients seek to decrease, or reverse, effects of sun damage on the skin. Hyaluronic acid (HA), a naturally occurring glycosaminoglycan found in the body, has enormous potential to bind water which allows the skin to retain moisture and maintain elasticity. Read More

Photodynamic therapy for solid tumors: A review of the literature.

Photodermatol Photoimmunol Photomed 2019 Sep 18;35(5):295-303. Epub 2019 Jun 18.

Harvard Medical School, Boston, Massachusetts, USA.

Photodynamic therapy (PDT) utilizes a sensitizer agent and light to produce selective cell death. Dermatologists are familiar with PDT for the treatment of actinic keratoses and early nonmelanoma skin cancers, and recent studies have elucidated that PDT has resulted in improved morbidity and secondary outcomes for the treatment of various cancerous and precancerous solid tumors. Light source and dosimetry may be modified to selectively target tissue, and novel techniques such as fractionation, metronomic pulsation, continuous light delivery, and chemophototherapy are under investigation for further optimization of therapy.

Split-face study comparing conventional MAL photodynamic therapy in multiple actinic keratosis with complete time vs. half-time red light LED conventional illumination.

J Eur Acad Dermatol Venereol 2019 Aug 15;33(8):1529-1534. Epub 2019 Apr 15.

Dermatology Department, Hospital Ramón y Cajal, Madrid, Spain.

Background: Conventional photodynamic therapy (PDT) with methylaminolevulinic acid (MAL) and daylight PDT have demonstrated similar efficacy in the treatment of actinic keratosis (AK). The reason for the use of daylight is to reduce pain during illumination but daylight has the limitation of the weather conditions. The difference in the doses of red light applied between these two methods suggests that an intermediate dose with red light conventional illumination could be effective in PDT of AK. Read More

An update on topical photodynamic therapy for clinical dermatologists.

J Dermatolog Treat 2019 Dec 19;30(8):732-744. Epub 2019 Jun 19.

Veterans Affairs Medical Center , Brooklyn , NY , USA.

Photodynamic therapy (PDT) involves the application of a topical photosensitizer, irradiation with light, and oxygen to produce cytotoxic reactive oxygen species that selectively destroy damaged cells while leaving normal skin intact. Topical PDT is a commonly used treatment for non-melanoma skin cancers (NMSCs) due to its excellent clearance rate and cosmetic outcomes. However, PDT is emerging as an off-label treatment modality for many dermatological conditions. Read More
