On March 5, NJ.com cited several medical experts explaining the unusual marks on the US President's neck. The issue gained public attention on March 2, when Trump revealed a red area on the right side of his neck, extending to his hairline, during a Medal of Honor ceremony at the White House.

Speaking to The Daily Beast a day earlier, dermatologist Dustin Portela in Idaho suggested the red and peeling skin indicated the use of topical chemotherapy cream. Trump uses this medication to inhibit the development of pre-cancerous lesions or actinic keratosis. Dr. Portela considers Trump a typical case with a high risk of skin cancer due to his fair skin, light hair, and consistent outdoor activity.

Sharing this view, senior dermatologist Elizabeth Bahar Houshmand in Texas told HuffPost that the President is treating actinic keratosis caused by ultraviolet radiation. Expert Anthony Rossi from the David H. Koch Cancer Care Center predicted he applies topical chemotherapy medications such as 5-fluorouracil or imiquimod, typically for a 2-4 week course.

In contrast to these medical analyses, the President's personal physician, Sean Barbabella, offered a different explanation. He stated that Trump applies a common, prescription-strength preventive skin irritation cream. Patients apply the cream for one week, and the redness can persist for the next few weeks.

This dermatological issue emerged as the American public closely scrutinizes the health of the oldest president in history to take office. Many have previously observed bruising on his hands or swollen ankles. Last July, doctors diagnosed him with chronic venous insufficiency, a condition that makes it difficult for blood to pump from the legs back to the heart. Despite this, in an interview with The Wall Street Journal early this year, Trump maintained that he was in perfect health. He also admitted to taking more than the recommended dose of aspirin and regretted undergoing extensive diagnostic imaging tests, which he felt drew excessive public attention to his private life.
