Is nail fungus different from nail psoriasis?

Yes. Nail fungus is an infection from external sources that causes yellow/brown discoloration and a foul odor. Nail psoriasis is an autoimmune condition that causes "pitting" (tiny dents) and "oil drop" patches under the nail. Because they look similar, a professional diagnosis is essential to avoid using the wrong treatment.

❓ Frequently Asked Questions

Is nail fungus different from nail psoriasis?

Yes. Nail fungus is an infection from external sources that causes yellow/brown discoloration and a foul odor. Nail psoriasis is an autoimmune condition that causes “pitting” (tiny dents) and “oil drop” patches under the nail. Because they look similar, a professional diagnosis is essential to avoid using the wrong treatment.

What causes a dark streak to appear on a fingernail?

A dark vertical line can be a harmless “mole” under the nail or staining. However, it can also be a sign of subungual melanoma, a serious form of skin cancer. Any new or changing dark band should be evaluated by Yelena Terushkin, PA-C, immediately for a potential biopsy.

How long does it take for a damaged nail to grow back?

Fingernails take about 6 months to grow from cuticle to tip, while toenails can take 12 to 18 months. Because growth is slow, many nail treatments require several months of consistency before you see a clear, healthy nail emerge.

Can I get a prescription for nail fungus via Telehealth?

Yes. Through a virtual consultation, we can review high-resolution photos of your nails. If the diagnosis is clear, we can send a prescription for advanced antifungal lacquers or oral medications to your local NYC pharmacy.

 Trustindex verifies that the original source of the review is Google. I cannot recommend Yelena Terushkin, PA-C highly enough. After another dermatologist at a different practice misdiagnosed my skin concerns, I sought a second opinion with Yelena. She identified both a melanoma and a basal cell carcinoma that had been missed, and I genuinely believe that decision changed my life. As frightening as the diagnosis was, Yelena handled every step with incredible compassion, professionalism, and empathy. She took the time to thoroughly explain my pathology results, walk me through each treatment option, answer every question I had, and ensure I understood exactly what came next. I never felt rushed, and I always felt like she truly cared about me as a person, not just a patient. She also emphasized the importance of routine skin checks moving forward, helping me understand that early detection is one of the most powerful tools we have in preventing serious outcomes. That education has completely changed the way I approach my health. I will always be grateful to Yelena for her expertise, her kindness, and her diligence. She caught what someone else missed, and because of her, I have the opportunity to move forward with treatment early. If you're looking for a dermatology provider who is exceptionally knowledgeable, compassionate, and meticulous, I cannot recommend Yelena Terushkin enough. She has earned my trust and gratitude for life.

 Trustindex verifies that the original source of the review is Google. I finally tried microneedling after seeing coworkers get amazing results. The effect is WOW!! Dr. Terushkin warned me about a couple of days of redness but the results after that are totally worth it.

 Trustindex verifies that the original source of the review is Google. I just had a cyst removed; it was an amazing experience overall, doctor was kind, gentle and very emphatetic. Did a magnificent job closing me up as well; as I needed stitching and had previous bad experiences on the matter, I am utterly relieved by the craftsmanship. 5/5! I totally recommend

 Trustindex verifies that the original source of the review is Google. I went for Botox and fillers and she has completely transformed my face in the best way. My forehead is now totally smooth with zero wrinkles, and my jawline looks so much more lifted and defined. She subtly reshaped my whole facial structure without it looking obvious or overdone at all. I still look like me, just a fresher, more rested version. The whole procedure was quick with literally zero discomfort, and her eye for detail is insane. I keep getting compliments and feel so much more confident. If you’re on the fence, just book it, she’s the real deal! 🙌
