White sponge nevus is an autosomal dominant skin disorder characterized by white, irregular, diffuse plaques mainly affecting the oral mucosa. Histological findings of white sponge nevus are characteristic but not pathognomonic. We report a case of an oral white sponge nevus in a 6-year-old girl, which poses a problem in differential diagnosis with oral candidiasis. No treatment was performed because of the benign and asymptomatic nature of the lesions.
Background: Phototherapy is a branch of physical therapy that employs natural or artificial light in the treatment of dermatoses. It includes UVA irradiation, which is absorbed in the deep layers of the skin, and UVB penetrates into the epidermal layer and has a significant ability to cause erythema. Materials and Methods: This was a retrospective study of records of patients with Scleroderma-like disorders treated with narrow-spectrum phototherapy in the phototherapy unit from April 2021 to April 2022. Results: In our group, NB-UVB treatment had a favorable safety profile and was typically well tolerated by patients, side effects were limited to 2 cases of transitory erythema and one case of mild hyperpigmentation. Conclusion: To our knowledge, this was the first study of the overall efficacy of NB UVB in these indications. Additionally, longer-term studies are needed to investigate long-term results, safety, and effectiveness when combined with other treatments.
Annular atrophic lichen planus is the most rare variant of lichen planus. A 8-year-old patient presented with a 2-year history of a pruritic eruption on the trunk and extremities, characterized by several annular lesions. The lesions had an erythematous papular border with an atrophic center. Histopathologic examination objectived a typical features of lichen planus. The patient had been treated successfully with high-potency topical steroids. We add a new case of annular atrophic lichen planus in childhood to the literature.
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.
