Dr. Lindsey Zubritsky, a dermatologist with 1.4 million TikTok followers, is warning people to check their nails for vertical lines that could indicate subungual melanoma, a rare form of skin cancer. This type of melanoma is not common, accounting for only 0.7% to 3.5% of all malignant melanomas worldwide, but it can be serious. Survival chances depend on the stage of cancer at diagnosis and how far it has spread. Certain characteristics, such as age, darker skin, and a family history of melanoma, increase the risk of developing subungual melanoma.
While the exact cause of subungual melanoma is unknown, it is not believed to be linked to sun exposure. The condition typically appears as a brown-black discoloration of the nail bed, often being misdiagnosed as a fungal infection. Subungual melanomas are most common on the big toe and thumb but can occur on any finger or toe. Dr. Zubritsky advises that not all dark streaks on nails are dangerous, explaining that a longitudinal melanonychia, which is a benign brown or black vertical nail streak, is more likely in many cases.
It is important to differentiate between subungual melanoma and a subungual hematoma, which is the pooling of blood under the nail due to trauma. Hematomas will typically grow out over time and are not dangerous. Dr. Zubritsky also points out the importance of seeking medical help if Hutchinson’s sign is noticed, which is when there is discoloration or pigmentation starting to creep up from the nail into the skin. This could be a sign of a subungual melanoma and should be investigated by a healthcare professional.
Dr. Zubritsky emphasizes the need for awareness about the signs of subungual melanoma, as it can be easily missed if not properly recognized. By urging her social media followers to check their nails for any concerning changes, she hopes to educate and inform the public about this rare but serious form of skin cancer. Being aware of the risk factors and symptoms of subungual melanoma is crucial for early detection and prompt treatment, ultimately improving outcomes for those affected by this condition.
The information provided by Dr. Zubritsky serves as a valuable reminder for individuals to pay attention to changes in their nails and seek medical attention if anything suspicious is noticed. By spreading awareness on platforms like TikTok, she is able to reach a wide audience and potentially help individuals identify and address potential health concerns early on. Encouraging proactive skincare practices, such as regular nail inspections, can play a significant role in preventing serious conditions like subungual melanoma from being overlooked or misdiagnosed.
Overall, Dr. Zubritsky’s message underscores the importance of proactive self-care and vigilance when it comes to recognizing potential signs of skin cancer. By educating the public about subungual melanoma and providing guidance on what to look for, she is empowering individuals to take charge of their health and seek appropriate medical attention when needed. Through her online presence and outreach efforts, Dr. Zubritsky is making a positive impact in raising awareness about this rare but critical issue, potentially saving lives by promoting early detection and treatment of subungual melanoma.
