Nail care starts with knowing when a change is cosmetic and when it is a sign of disease. We evaluate abnormal nails, diagnose the cause, and recommend medical or procedural options that balance health and appearance. If a nail is thickened, discolored, painful, separating, or has a new spot, those are reasons to see a dermatologist.
What is nail care in a dermatology practice
Nail care in dermatology covers diagnosis and treatment of disorders that affect fingernails and toenails. We treat infections, inflammatory conditions, trauma related changes, tumors that involve the nail apparatus, and chronic nail problems that affect daily life. Our approach combines an examination of the nail plate and surrounding skin, targeted testing when needed, and a personalized treatment plan that may include topical therapy, oral medication, or a minor in office procedure.
At Greenblatt Henry A MD | Horizon Family Medical Group | Dermatology we provide both medical and cosmetic care for nails. That means we address symptoms like pain and infection, and we also help restore appearance when that is an important goal.
Why nail care matters in Newburgh and the Hudson Valley
Nail conditions affect work, footwear choices, social comfort, and sometimes overall health. In our region, seasonal activities like gardening, hiking in the Hudson Valley, and recreational sports can lead to trauma that causes persistent nail problems. Local climate and footwear choices also influence fungal infections of toenails.
Some nail changes are a sign of systemic disease or medication side effects. Early evaluation helps rule out serious causes and avoids unnecessary treatment. We coordinate with referring physicians when a nail condition suggests a broader health issue.
Key concepts in nail care
How we think about nail problems
- Visual signs matter. Color change, thickening, splitting, lifting, and pain are primary clues.
- History guides testing. When a problem follows trauma, a different diagnostic path is needed than when it develops slowly over months.
- Testing clarifies diagnosis. Microscopy, fungal culture, or a nail clipping for pathology may be needed before we choose a treatment.
- Treatment is tailored. Options include topical antifungal agents, oral medication, intralesional injections, minor procedures, and management of underlying inflammatory disease.
- Appearance and function both matter. We balance cosmetic goals with medical safety.
Common nail conditions and how we evaluate them
Below are common causes of nail symptoms and the key elements of evaluation we use.
Common diagnoses
- Onychomycosis, or fungal nail infection. Often thickened and discolored nails, more common in toes. Diagnosis may use potassium hydroxide preparation, culture, or nail clipping sent for pathology.
- Nail psoriasis. Pitting, oil spot change, thickening, or separation of the nail plate. Often occurs with skin or joint disease and needs a holistic plan.
- Traumatic nail dystrophy. Results from repeated pressure or injury. Patterns and history point to trauma rather than infection.
- Paronychia and bacterial infection. Redness, tenderness, pus around the nail fold. Treatment varies from topical care to oral antibiotics when needed.
- Nail unit tumors. New pigmented bands or rapidly changing lesions of the nail warrant prompt evaluation and sometimes biopsy, because rare tumors can arise in the nail unit.
How we examine a nail
Our clinic performs a focused nail exam. We look at the nail plate, the fold, the lunula, and the surrounding skin. We compare the affected nail to the others. When testing is required we perform or arrange for a KOH preparation, fungal culture, or a nail clipping for pathology. If there is concern for a tumor we follow established steps to biopsy and analyze the tissue safely.
Comparison of selected nail conditions
| Condition | Typical sign | Usual testing | Common treatments |
|---|---|---|---|
| Onychomycosis | Thickened yellow or brown nail, crumbling | KOH, culture, nail clipping | Topical or oral antifungals, debridement |
| Nail psoriasis | Pitting, oil drop, nail separation | Clinical diagnosis, skin or nail biopsy if uncertain | Topical steroids, systemic psoriasis treatments, nail care |
| Traumatic dystrophy | Irregular thickening after injury, single nail affected | History and exam, imaging only if bone injury suspected | Conservative care, protective footwear, sometimes nail procedure |
| Paronychia | Red, painful swelling around nail fold; possible pus | Clinical exam, culture if recurrent | Drainage if needed, topical or oral antibiotics, antifungals for chronic cases |
When to see a dermatologist for nail problems
Consider evaluation by a dermatologist if you have
- New nail discoloration that does not improve
- A single dark band or a rapidly changing pigmented streak in the nail
- Pain, persistent thickening, or a nail separating from the nail bed
- Recurring or long standing nail infections
- Nail changes with skin disease such as psoriasis or eczema
- Concerns about appearance after at home measures have not helped
Pro tip: Take a clear photo of the nail in daylight and bring it to the visit. A photo of how the nail looked weeks earlier helps us track progression and plan the right test.
What tests and treatments look like in our clinic
We follow a stepwise process to avoid unnecessary treatment and to reach a clear diagnosis.
- Focused history and exam. We ask about onset, symptoms, footwear, hobbies, prior treatments, and any skin disease.
- Targeted testing. For suspected fungal infection we may perform a KOH exam in office and send a clipping for confirmation. For uncertain lesions a nail clipping or a small biopsy may be taken under local anesthesia.
- Personalized treatment plan. Depending on the diagnosis we select topical therapy, oral medication, localized injections, or a minor procedure. We explain benefits, risks, and expected timeline for improvement.
- Follow up. Nails grow slowly. We schedule follow up to monitor improvement and adjust therapy. We coordinate care with your primary care provider when needed.
We take care to preserve nail structure when possible and to choose treatments that fit your goals and medical history.
Common questions patients ask
Can nail fungus be cured
Many fungal nail infections respond to treatment, but nails grow slowly. Improvement can take months, and a full normal looking nail may take a long time. Success depends on the extent of the infection and whether the chosen medication reaches the fungus.
Is a biopsy of the nail painful
We perform nail biopsies with local anesthesia. You may feel pressure during the procedure, but we control pain with numbing medication. We will explain aftercare and what to expect while the nail grows out.
Can nail changes mean another health problem
Yes. Certain nail findings can be linked to psoriasis, thyroid disease, or other systemic issues. If we suspect a broader condition we coordinate testing or refer back to your primary care physician.

Key takeaway
Nail problems have many causes. Accurate diagnosis requires a careful exam and sometimes laboratory testing. We tailor treatment to the underlying cause and to your goals for function and appearance. If a nail is painful, rapidly changing, or has an unusual pigmented band, seek evaluation so we can identify the cause and plan appropriate care.
Frequently asked questions
How do you diagnose fungal nail infection
We start with a clinical exam. When the diagnosis is uncertain we perform a KOH preparation or send a nail clipping for fungal culture or pathology to confirm onychomycosis before starting long term systemic therapy.
How long does treatment for a nail condition take
Treatment timelines vary. Medical therapy can take weeks to months, and visible improvement may lag because nails grow slowly. We discuss realistic timelines for the specific diagnosis and treatment chosen.
Are nail biopsies safe
Nail biopsies are performed with local anesthesia and carried out in a way that minimizes harm to the nail matrix. We explain risks and expected healing before any procedure.
Can nail problems be a sign of skin cancer
Certain pigmented bands or a changing dark streak in the nail can be a sign of a tumor in the nail unit. We evaluate any concerning pigment and perform a biopsy when indicated to rule out malignancy.
