Erythematous plaques on the bilateral dorsal hands.

Neutrophilic dermatosis of the dorsal hands is a rare cutaneous disorder characterized by the sudden onset of painful, haemorrhagic, and pustular bullae with violaceous rims on the dorsal aspects of the hands. Here we present a 61-year old male with a 1-week history of tender, haemorrhagic, and pustular bullae on both dorsal hands, evolving into ulcerative plaques with haemorrhagic crusting over 5 days. A 4 mm lesional punch biopsy revealed a diffuse dermal infiltrate of numerous neutrophils intermixed with lymphocytes and histiocytes, along with epidermal spongiosis and neutrophilic exocytosis. No leukocytoclastic vasculitis was identified. The provided images document the progression of this rare inflammatory process. Understanding such cases is crucial for accurate diagnosis and management.

Nirmatrelvir-ritonivir, COVID-19, and possible adverse cutaneous reactions.

Nirmatrelvir-ritonivir (Paxlovid) recently received emergency use authorization for the treatment of coronavirus disease 2019 (COVID-19). Literature has linked numerous cutaneous adverse effects to nirmatrelvir and ritonavir, the copackaged tablets within Paxlovid. A review and comparison of these adverse effects to the common cutaneous manifestations of COVID-19 is provided. Numerous drug-to-drug interactions exist between nirmatrelvir-ritonivir and commonly-used medications within dermatology.

Social Media as a Medium for Dermatologic Education.

Purpose of Review: We explore the utility of social media platforms as educational tools in dermatology, providing a summary of how these sites are used by the public and dermatologists alike, and demonstrating ways these findings may be applied for educational purposes. Recent Findings: Over half of the world's population utilizes social media platforms. More recently, these platforms have increasingly been used for educational purposes. In the field of dermatology, a large portion of the educational content is coming from users with no formal medical or dermatologic training. Summary: Each of the top five social media platforms in the world (Twitter, Instagram, TikTok, YouTube, and Facebook) has unique qualities which people may utilize to educate fellow users. As more of the population seeks online health information and education, it is important that dermatologists, while taking ethical considerations into account, become more comfortable facilitating educational content on social media.
