Further, Dr. Friedman offered methods for deciding when to perform the above tests.
The melanoma “epidemic” from a dermatopathologist’s perceptive was presented next by Earl Glusac, MD, assessing previously published literature about the direction and prevalence of melanoma. Dr. Glusac identified certain factors that contributed to this “epidemic,” and the surrounding misconceptions, such as lesion size in relation to histologic criteria, screening problems, “no mission” motivation, and melanoma reservoir.
Next, Jason B. Lee, MD, discussed melanoma diagnosis from a clinician’s perspective. Dr. Lee first assessed the efforts needed to detect melanoma early. Like Dr. Glusac, Dr. Lee also discussed the melanoma “epidemic,” submitting the steady increase in mostly Stage 0 and 1 melanoma would not be the only Stages to raise if it was a true epidemic. Further, Dr. Lee explained how incidence rates might be raising, but mortality rates are remaining low and steady. After, Dr. Lee highlighted the three 3 categories of melanoma: slow-growing melanomas with chronic sun on head and neck, slow-growing melanomas with intermittent sun exposure and melanocytic nevi, and fast-growing aggressive melanomas (not correlated to sun exposure or melanocytic nevi). To conclude, Dr. Lee provided clinical scenarios of overdiagnosis of melanoma.
Lastly, Chauncey McHargue, MD, offered more insight on the melanoma “epidemic” as well. Dr. McHargue presented information from the SHEER database for cancer statistics, several articles on melanoma prevalence, the trend of related mortalities rates over the years (and the “mortality curve” during the 1980s), and research on the discordance in incidence and mortality of melanoma. After analyzing the ample amount of information packed in this session, Dr. McHargue concluded with the medical advancements that have evoked a 100-percent reduction in excess mortality over the past 30 years and the increase in incidence rates were mainly due to aggressive screening. In short, “there is no melanoma epidemic,” Per Dr. McHargue.

Further, Dr. Armstrong covered management of pediatric psoriasis and how certain treatments, such as ustekinumab, perform in children. To end this session, Dr. Armstrong discussed AAD-NPF phototherapy guideline updates.
With the assistance of specific case reports and various clinical studies, Nehal N. Mehta, MD, MSCE, FAHA, examined the link between the effects of inflammation and cardiometabolic diseases. The first case that was featured pertained to hypertension and untreated psoriasis. Dr. Mehta described the laboratory data involved to further depict how psoriasis is often correlated to cardiovascular disease. However, Dr. Mehta explained that biologics can be utilized to reduce systemic inflammation from psoriasis, as well as coronary plaque burden. After providing data that included many patients treated with biologics, Dr. Mehta discussed the moderation of lipid-rich neurotic core after one year of treatment. By reverting to the first case, Dr. Mehta concluded that inflammation produces lipid streaks in the arteries that lead to non-calcified plaque and eventually high-risk plaque in such populations and why biologic therapies can decrease the occurrence and exacerbation of the above process.
The final presenter, Richard GB Langley, MD, examined the treatment of mild-to-moderate plaque psoriasis with modern systemic therapies, deconstructing psoriasis severity classification and when to suggest such therapies. To end, Dr. Langley offered physicians introspective questions when constructing a treatment plan for the patient.
