Pedunculated SKs or SKs in intertriginous areas, hair-bearing areas, or within 5 mm of the orbital rim were excluded. 2018 Sep 1; [PubMed PMID: 30235378], Brando ML,Oliveira Lima CM,Moura HH,Ishida C,Campos-do-Carmo G,Cuzzi T,Ramos-E-Silva M, Dermatoscopic Findings of Seborrheic Keratosis in Melanoma. Therefore, HP40 may be better reserved for the treatment of facial SKs. 2018 Mar; [PubMed PMID: 28902028], Kao S,Kiss A,Efimova T,Friedman AJ, Managing Seborrheic Keratosis: Evolving Strategies and Optimal Therapeutic Outcomes. 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). While the occurrence of SK on the conjunctiva is rare, it can be considered in the differential diagnosis with patients presenting with conjunctival lesions. Immature epidermal keratinocytes slowly proliferate leading to macules, papules, and plaques known as seborrheic keratoses. Uses for Hydrogen Peroxide 40% Hydrogen peroxide 40% has the following uses: Hydrogen peroxide 40% is indicated for the 2019 Jul 1;18(7):s173-177. Induction of terminal differentiation in melanoma cells on downregulation of beta-amyloid precursor protein. Herzog V, Kirfel G, Siemes C, Schmitz A. Copyright 2023, Selected Revisions January 8, 2018. 2015;14(10). Kwon OS, Hwang EJ, Bae JH, et al. MeSH Hydrogen Peroxide Topical Solution Effective for Seborrheic [9], Seborrheic keratosis is a benign tumor and does not typically require treatment; however, the majority of patients seek therapeutic interventions electively for cosmetic changes or to improve associated symptoms such as ocular irritation. 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. Both studies were recently published in The BMJ. WebAbstract. CONTRAINDICATIONS None. Similarly, the risks of pigmentary changes and scarring from HP40 were lower for the face than other locations. After 3 weeks, the SK can be re-treated if satisfactory clearance was not achieved. There are various subtypes of seborrheic keratosis, including acanthotic, hyperkeratotic, clonal, adenoid, irritated, and melanoacanthoma. Available from: Tsambaos D, Monastirli A, Kapranos N, et al. Epub 2022 Nov 13. The color of these lesions can vary from light to dark brown, yellow, and grey, and they can present as an isolated lesion to tens or even hundreds of lesions. This site needs JavaScript to work properly. At the end of the study (day 106), HP40 resulted in a significantly higher rate of complete clearance of all four SKs than vehicle; however, the rate of clearance of all four SKs with HP40 was low overall (4%, 8% per study for HP40 versus 0% for both studies for vehicle). Ranasinghe GC, Friedman AJ. Another modality for the treatment ofseborrheic keratosis would shave excisions. For instance, the thin SC of the face may allow enhanced penetration of HP40 compared to other anatomical sites. The researchers tested blood levels of the study volunteers and assigned them on a random basis to get vitamin D supplements or not.

Overall there have been multiple small studies, which have some efficacy in the treatment of seborrheic keratosis, however, further studies are needed. A dermatologist referral should be a consideration in patients with a high number of lesions and high clinical suspicion of malignancy for a more thorough and team-oriented approach. Evaluation of toxicity and Stat3 activation induced by hydrogen peroxide exposure to the skin in healthy individuals. seborrheic keratosis in elderly patients This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. This online resource is available under the Health eGuides tab at PeoplesPharmacy.com. [26][2] Sudden eruption of multiple seborrheic keratoses, known as the sign of Leser-Trelat can be a poor prognostic sign due to its association with internal malignancy. Hydrogen Peroxide 40% Q: You recently had a letter from a woman whose doctor told her to use glucosamine and chondroitin for arthritis pain relief. [11] Often further workup is not needed. J Dermatol. The application can also be time-consuming, though extenders or even staff members can apply it. [10][11] Overall, the application of topical hydrogen peroxide was well tolerated and was effective in the removal of seborrheic keratosis. [21], Pathology shows proliferation of keratinocytes with keratin-filled cysts. Before [12], The pathogenesis of seborrheic keratosis (SK) remains poorly understood. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Sayan A, Sindel A, Ethunandan M, et al. Rongioletti F, Corbella L, Rebora A. [9], Seborrheic keratosis is a benign proliferation of immature keratinocytes between the basal layer and the keratinizing surface of the epidermis. PMID: 10442897. de Loof M, van Dorpe J, van der Meulen J, et al. Hydrogen peroxide is commonly used as an antimicrobial and may promote wound healing, in part via its debriding properties. In cases of conjunctival lesions, histopathology is crucial in differentiating a malignant melanoma from a benign, and exceedingly rare, conjunctival seborrheic keratosis. [28], A diagnosis of seborrheic keratosis is often confirmed with histology in addition to associated findings such as age, skin pigmentation, and quantity and quality of lesions. HP40, although less effective, has a better safety profile than other treatment options. Spanish. 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. Excipients in commercially available drug preparations may have clinically important effects in some individuals; consult specific product labeling for details. What can a doctor do for seborrheic keratoses? Dermatologists use one of several methods to remove a seborrheic keratosis. Liquid nitrogen can take it off (although that can ultimately leave a tiny white spot), or it can be scraped off with a curette. Some doctors prefer to use electrocautery to sculpt the growth off. Patients with high numbers ofseborrheic keratoses should receive careful screening, as there can be an increased chance of missing co-existing melanoma or pigmented basal cell carcinoma.
