Background. Seborrheic keratosis is a benign skin tumor removed through electrodessication, cryotherapy, or surgery. Alternative options may be beneficial to patients with contraindications to standard treatment, or those who prefer a non-invasive approach. Objectives. To determine the effectiveness and safety of topical medications on seborrheic keratosis in the clearance of lesions, compared to placebo or standard therapy. Methods. Studies involving seborrheic keratosis treated with any topical medication, compared to cryotherapy, electrodessication or placebo were obtained from MEDLINE, HERDIN, and Cochrane electronic databases from 1990 to June 2018. Results. The search strategy yielded sixty articles. Nine publications (two randomized controlled trials, two non randomized controlled trials, three cohort studies, two case reports) covering twelve medications (hydrogen peroxide, tacalcitol, calcipotriol, maxacalcitol, ammonium lactate, tazarotene, imiquimod, trichloroacetic acid, urea, nitric-zinc oxide, potassium dobesilate, 5-fluorouracil) were identified. The analysis showed that hydrogen peroxide 40% presented the highest level of evidence and was significantly more effective in the clearance of lesions compared to placebo. Conclusion. Most of the treatments reviewed resulted in good to excellent lesion clearance, with a few well tolerated minor adverse events. Topical therapy is a viable option; however, the level of evidence is low. Standard invasive therapy remains to be the more acceptable modality.
performs very well in constructing representations of normalappearing skin, which may have implications for augmenting existing dermatology images for use in the training of future domain-specific models including smartphone-based clinical or dermoscopic image diagnosis. Future work may further elucidate the potential of DALL-E 2 for this application, as well as other potential uses for image generation such as virtual training environments, patient education, or device/product design.
A 67-year-old female with acute myelogenous leukemia, presented with a two-week history of enlarging ecchymosis-like plaques with hemorrhagic bullae on the right forearm and anterior legs, associated with fever, pain, and swelling. Tissue cultures were persistently negative. Lesions progressed despite broad-spectrum antibiotic coverage. Histopathology showed neutrophilic dermatitis, consistent with pyoderma gangrenosum. The patient was diagnosed with the bullous type. This type is rare with only two reported cases in the Philippines since 2011. Systemic glucocorticoids were given with note of dramatic improvement of the lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
