Introduction: Several studies investigated the use of dermoscopy in the delineation of Basal cell carcinoma (BCC) for Mohs micrographic surgery (MMS) with conflicting results
Objective: The purpose of this systematic review with meta-analysis was to evaluate the effectiveness of the use of dermoscopy-guided MMS in the treatment of BCC.
Methods: We included all comparative studies including more than twenty-five cases. Cases of BCC treated using dermoscopy-guided MMS (or slow MMS) were compared to those treated with curettage-guided MMS or “standard” MMS.
Results: A total of 6 studies including 508 BCCs were reviewed. There was no statistically significant difference in the proportion of total margin clearance on the first MMS stage between BCCs removed using dermoscopy-guided MMS and those that had curettage or visual inspection. However, lateral margin involvement was significantly lower in BCCs that had dermoscopy-guided MMS.
Limitations: Scarcity of research on this subject
Conclusions: Dermoscopy allows visualization of structures up to 1mm into the dermis, and therefore it is rational to use it for lateral margin evaluation. Currently, there are two comparative studies showing the efficacy of dermoscopy for lateral margin evaluation during MMS. Future studies are required to develop an evidence-based recommendation regarding the utility of dermoscopy in MMS.
Oral manifestations in syphilis are frequent through the different stages of the disease. Exclusive oral localization in secondary syphilis (SS) is yet uncommon. Delays in diagnosis are frequent in these patients. We describe a case of SS limited to the buccal mucosa with both serological and histological confirmation.
Pemphigus herpetiformis (PH) is a rare form of pemphigus, especially when occurring in childhood. Misdiagnosis is common in this age group. The disease exhibits diverse clinical and histological aspects. Further immunological investigations should be performed in order to make the right diagnosis with a correct management strategy.
Recognition of cutaneous myeloid sarcoma is important for all dermatologists to avoid further progression to acute myeloid leukemia. Nevertheless, we highlight the presence of a favorable clinical outcome in some patients with spontaneous regression.
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.
