From TikTok to Targeted Therapy: Shannon Trotter, DO, on Modern Dermatology Challenges

Shannon Trotter, DO, a board-certified dermatologist with DOCS Dermatology Group in Columbus, Ohio, shared practical insights from her SDPA Fall 2025 sessions on social media trends, lichenoid disorders, and granuloma annulare, as well as her vision for the future of dermatology.

In her first session of the day, Trotter emphasized the increasing influence of social media in shaping patient perceptions of skin health.¹ She noted that nearly 20% of patients consult apps and platforms such as TikTok before visiting their dermatologist.

“Social media is in fact the new WebMD,” she noted, underscoring the responsibility of dermatologists to stay informed about online trends and misinformation. She encouraged clinicians to engage online to promote accurate dermatologic education and build trust with digitally savvy patients.

In her advanced breakout discussion, “I'm Lichen It! Lichenoid Disorders in Dermatology,” Trotter sought to demystify this complex group of conditions.² She highlighted the heterogeneity of lichen planus, which may involve the skin, hair, nails, mucosa, and even internal organs such as the esophagus and bladder. Given the limited evidence-based treatment options, she urged clinicians to be creative and open to off-label therapies. Importantly, she drew attention to the rise in lichenoid drug eruptions associated with cancer immunotherapies and targeted treatments, encouraging dermatologists to maintain a high index of suspicion in such patients.

Trotter also addressed granuloma annulare in a microlearning session, describing it as one of her favorite yet often underestimated rashes.³ Although benign, she cautioned that it may be linked to autoimmune and lymphoproliferative disorders, including Hodgkin’s and non-Hodgkin’s lymphoma. She stressed the need for thorough workups and individualized, sometimes unconventional, treatment strategies.

Looking ahead, Trotter expressed enthusiasm for advances in artificial and augmented intelligence in dermatology, predicting that these technologies will enhance diagnostic accuracy and patient care. She also highlighted growing interest in longevity medicine, noting its intersection with aesthetics and inflammatory disease management.

Finally, Trotter invited colleagues and patients alike to explore her passion project, a podcast called “Derm-it Trotter! Don't Swear About Skincare." The show offers expert insights, clinical pearls, and accessible education to help both providers and the public navigate the ever-evolving world of dermatologic information.
