Hydrogen Peroxide 40% for the Treatment of Seborrheic Keratoses Eligible seborrheic keratoses could not be pedunculated or in an intertriginous area and had to be stable, typical, less than 0-2 mm thick, between 5 mm and 15 mm long/wide, and located on the extremities, trunk, or face, but not inside or within 5 mm of the orbital rim. The most common variant is acanthotic. Managing Seborrheic Keratoses: Evolving Strategies for Optimizing Patient Outcomes. Baumann LS, Blauvelt A, Draelos ZD, Kempers SE, Lupo MP, Schlessinger J, Smith SR, Wilson DC, Bradshaw M, Estes E, Shanler SD. By harnessing the oxidative capabilities of H2O2 , 1-2 treatments with HP40 produced a higher rate of clearance of four SKs per patient compared to vehicle in two phase 3 trials. Kwon OS, Hwang EJ, Bae JH, et al Seborrheic keratosis in the Korean males: causative role of sunlight. For topical use only. Available from: https://www.ncbi.nlm.nih.gov/books/NBK470554/. Hydrogen peroxide (H 2 O 2) is a product of respiration in mitochondria and an important oxidizing agent in biological systems.Previous investigations have shown the efficacy of H 2 O 2 in treating skin conditions such as seborrheic keratosis and actinic keratosis. These procedures require some type of local anesthesia, usually 1% lidocaine with or without epinephrine depending on the location of the lesion. Overlapping lesions or high numbers ofseborrheic keratosis can make the diagnosis and workup of these lesions more difficult. 8600 Rockville Pike Local skin reactions were predominantly mild, and usually consisted of stinging, crusting, transient pruritus, edema, scaling, and erythema that would most often resolve by the following visit. High-dose hydrogen peroxide for SKs Queratosis seborreica de la conjuntiva: informe de un caso [Seborrheic keratosis of conjunctiva: a case report]. Hydrogen Peroxide 40% Due to the high prevalence of this skin condition, it is crucial to biopsy those patients with atypical features and a higher clinical index of suspicion for malignancy. and transmitted securely. Inhibition of apoptosis may occur in SKs, contributing to their formation.4Additionally, mutations in the fibroblast growth factor receptor8 and oncogenic phosphoinositide 3-kinase pathway9 may impact their development; however, these changes are not present in all SKs so additional genes are likely involved.8, While SKs do not require treatment, patients often request removal to relieve symptoms of irritated SKs or for cosmetic reasons.10 The most common treatment is cryotherapy with liquid nitrogen; surgical therapies are also used including electrodessication, curettage, shave excision, or laser therapy.7,11, Among other side effects, these invasive methods can cause pain, bleeding, pigmentary changes, and scarring.7,12-15 The risk of pigmentary changes is especially high in patients with skin of color.7 These side effects motivated the pursuit for efficacious topical therapies that minimize long-term adverse effects. [14][15][16][19][20]. Copyright 2023, Selected Revisions January 8, 2018. Managing Seborrheic Keratosis: Evolving Strategies and Optimal Therapeutic Outcomes. This therapy is safe, effective, and well-tolerated by patients, according to research presented at the 2018 Fall Clinical Dermatology Conference, held October 18-21 in Las Vegas, Nevada. 2017;44(5):518-524. doi:10.1111/1346-8138.13657. Multiple familial seborrheic keratoses. - Full-Length Features Acta Dermatovenerologica Croat. While the risks of pigmentary changes and scarring at day 106 were low, especially for facial SKs, 98.8% of the study sample were FST I-IV, with only 7.3% having FST IV, so the effects on patients with FST IV or higher could not be adequately assessed.20 A study by Kao et al. 1999 Aug;106(8):1516-20. doi: 10.1016/S0161-6420(99)90446-3. The side effects of treatment were generally mild and included erythema, scaling, and hyperpigmentation. [11] Often further workup is not needed. Explain the common history and physical exam findings of seborrheic keratosis. Ranasinghe GC, Friedman AJ. Therefore, HP40 may be better reserved for the treatment of facial SKs. 11 SKs have a higher proliferative rate than normal keratinocytes, Hoffmann J, Twiesselmann C, Kummer MP, Romagnoli P, Herzog V. A possible role for the Alzheimer amyloid precursor protein in the regulation of epidermal basal cell proliferation. These lesions do not usually self resolve. PMID: 31730314 No abstract available SK lesions are papules and/or plaques that have a predilection for the eyelid, forehead, and trunk; however, they can occur anywhere on the body with sparing of the palms and soles. J Dermatolog Treat. CONTRAINDICATIONS None. Although laser therapy has been shown to be efficacious, it is more expensive than the other treatment options and its benefit of use over other therapeutic methods has not been established. Given the high prevalence and variable clinical appearance of SK, it is important for providers to be familiar with its diagnosis and management. There are a number of treatment options available, including cryotherapy, excision, and topical hydrogen peroxide solution. Hydrogen peroxide 40% is available in the following dosage form(s) and strength(s): Topical solution: 40% (w/w) hydrogen peroxide. These tumors can generally occur anywhere on the body, except for the palms, soles, and mucous membranes. Relevance to patient care and clinical practice: The sign of Leser-Trelat refers to the sudden appearance of seborrheic keratosis that is suggestive of internal malignancy, such as gastrointestinal or pulmonary carcinomas. Peredo M, Murphy E, Karibayeva D. Clinical experience with 40% hydrogen peroxide topical solution for the treatment of seborrheic keratosis. It is not a natural treatment, however, and it is not a do-it-yourself project. The application can also be time-consuming, though extenders or even staff members can apply it. 2019 Jul 1;18(7):s173-177. used an ex vivo model of human FST V skin to explore the toxicity of HP40 (1 and 2 L) compared to cryotherapy (5- and 10-second cycles).23 A colorimetric MTT assay was used to measure overall cytotoxicity and S100 stained-melanocytes were quantified to assess melanocyte toxicity. FGFR3 mutations in seborrheic keratoses are already present in flat lesions and associated with age and localization. This method utilizes liquid nitrogen or CO2 to rapidly freeze/thaw the targeted cells, resulting in cell death. In their column, Joe and Teresa Graedon answer letters from readers. All of these subtypes of seborrheic keratosis have three features in common: hyperkeratosis, acanthosis, and papillomatosis. Eskata: Hydrogen Peroxide Solution for SKs | RealSelf I have an arthritic thumb, and nothing had helped. Hydrogen peroxide 40% (Eskata) for seborrheic keratoses. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Seborrheic Keratosis - Reverse Engineering A Home Treatment [18][25]. Objective: Hydrogen peroxide 40% (HP40) was approved by the US Food and Drug Administration for topical treatment of seborrheic keratosis (SK) in December 2017. - Drug Monographs 2017 Nov 1; [PubMed PMID: 29141054], DuBois JC,Jarratt M,Beger BB,Bradshaw M,Powala CV,Shanler SD, A-101, a Proprietary Topical Formulation of High-Concentration Hydrogen Peroxide Solution: A Randomized, Double-Blind, Vehicle-Controlled, Parallel Group Study of the Dose-Response Profile in Subjects With Seborrheic Keratosis of the Face. Seborrheic keratosis is a common type of epidermal tumor that is prevalent throughout middle-aged and elderly individuals. Dermatoscope findings forseborrheic keratosis generally show milia cysts, comedo-like openings, fissures, and ridges. Only 1 patient experienced a TEAE that was treatment-related (contact/skin irritation). The clearance rate was higher for the face than the trunk and extremities. Int J Oral Maxillofac Surg. They are typically slow-growing, can increase in thickness over time, and they rarely resolve spontaneously. [26], The prognosis of seborrheic keratosis is excellent. This procedure is performed in an outpatient setting with local anesthesia and uses a curette to remove epidermal tissue followed by electrodessication with a hyfrecator or cautery unit. Review of the typical lesion and its variants. The location of the lesion should also be considered as cryotherapy in the periocular area can lead to eyelid notching or contour irregularities. The mechanism by which HP40 destroys keratinocytes is not fully elucidated, but is thought to involve H2O2s oxidizing power21 as both a direct oxidant and indirect oxidant through the formation of hydroxyl radicals.25 When this oxidative stress overwhelms the antioxidant properties of the skin, H2O2 can lead to cellular destruction by damaging proteins, lipids, and nucleic acids.25 Applied at a supra-physiologic concentration, a portion of the HP40 dose likely diffuses through the stratum corneum (SC) and into the epidermis.20,21 Free radicals generated by H2O2 can then induce apoptosis or necrosis of seborrheic keratinocytes among other cell types (Figure 1).
