Skin Checks & Rashes: What Primary Care Can (and Can't) Tell You

Reviewed by the Evolve Health clinical team · 2026-10-17 · 8 min read

The skin questions we hear sound like this: "This mole changed — do I need to worry?" "Is this ringworm or eczema, because the cream I bought is not working." "Do I really need a dermatologist for this, or can you just look at it?" They are good questions, because the honest answer is "it depends" — on what the spot looks like, how it has changed, and where the line sits between an exam and a procedure. This guide walks that line plainly: what a primary care skin visit covers, the ABCDE check you can do at home, and the warning signs that should move you faster.

What a primary care skin visit covers

A skin visit at Evolve Health starts with looking — carefully, in good light, at the spot that brought you in and any others you want checked. Tell us which ones are new, which have changed, and which simply worry you; the ones you flag get examined first. From there, most of what walks in is diagnosable and treatable in primary care:

• Moles and spots — examined up close, measured, compared against the ABCDE warning signs below, and documented in your chart so change over time can be tracked honestly instead of from memory.
• Eczema and contact dermatitis — the itchy, dry, or weeping patches from dry skin, soaps, metals, plants, or a new product. Treatment is usually a topical steroid cream plus a trigger plan.
• Fungal infections — ringworm (a ring-shaped rash that has nothing to do with worms), athlete's foot, and jock itch respond to antifungal creams, or an oral antifungal when the area is large or the cream has failed.
• Hives — raised, itchy welts that come and go. Antihistamines are the mainstay; we also work through likely triggers and flag the allergic reactions that are emergencies.
• Psoriasis patterns — thick, scaly plaques, often on elbows, knees, or the scalp, managed with prescription topical treatments and monitored over time.
• Shingles — a painful, blistering stripe on one side of the body. Antiviral medicine works best when started within 72 hours of the rash appearing, so this one should not wait out the weekend.
• Skin infections — spreading redness, warmth, and tenderness (cellulitis) or crusted sores (impetigo) are treated with antibiotics in oral or topical form, as the case calls for.

When medicine is part of the plan, it is prescribed by class and purpose — a topical steroid to calm inflammation, an antifungal to clear the infection, an antihistamine to settle itching — and sent to your pharmacy when appropriate.

The ABCDE guide to moles — and its limits

The ABCDE check is the standard first screen dermatologists teach for spotting melanomas early. Run through it on any mole you are watching:

Two honest limits matter. First, ABCDE is a screening aid, not a diagnosis — it flags spots that deserve an in-person look; it cannot clear one. Most moles are harmless, and many flagged spots turn out to be benign, but the only way to know what a suspicious lesion actually is is a biopsy, which is a dermatology procedure. Second, trust the "ugly duckling" rule alongside the letters: a spot that simply looks different from all your others — or a sore that does not heal — deserves an exam even if it checks none of the boxes.

What primary care can't do — stated plainly

We would rather be direct about this than vague: Evolve Health does not perform skin biopsies or surgical excisions, and we do not remove moles or spots for cosmetic reasons. No primary care exam — ours or anyone's — can diagnose a suspicious lesion by sight alone with certainty, and any clinic that implies otherwise is overselling. Here is what happens instead when a spot concerns us: we measure and document its size, appearance, and location in your chart, explain exactly what we saw and why it needs a specialist's eye, and refer you promptly to a dermatologist, who can biopsy it. Starting the process here means the spot is examined this week and the referral goes out with real clinical notes attached, rather than after months on a waitlist for a first look.

The Texas sun does not take the winter off

North Texas UV exposure is a year-round fact, not a summer one — Denton gets strong sun in January too, and cumulative exposure is what skin remembers. It adds up fastest for people who work outdoors — construction, roofing, landscaping, agriculture, delivery and truck driving — and one group deserves a specific mention: drivers. U.S. research has found skin cancers appearing more often on the left side of the body, the driver's side, because ordinary side-window glass lets much of the sun's UVA through even when it blocks the burning UVB. Hours on I-35 count as sun exposure whether they feel like it or not. The everyday defenses are unglamorous and effective:

• Use broad-spectrum sunscreen, SPF 30 or higher, on face, ears, neck, and the backs of hands — and reapply about every two hours outdoors, sooner after sweating.
• Cover up where you can: a hat with a brim, long sleeves, and sunglasses beat sunscreen alone for all-day outdoor work.
• Mind the midday hours when errands and breaks can be shifted; shade is real protection.
• Check your own skin monthly and your driver's-side arm, hand, and face especially — and get new or changing spots looked at rather than watched for a year.

Our guide to sun safety and skin cancer in Texas goes deeper on protecting kids, athletes, and outdoor workers through a Texas summer.

When a rash is urgent

Most rashes are uncomfortable, not dangerous. These are not most rashes — get same-day or emergency care for:

• Spreading redness with fever, warmth, or increasing pain — signs of a skin infection that needs antibiotics promptly.
• Blistering, skin pain, or peeling, especially if it is spreading.
• Any rash involving the eyes, mouth, or lips — including shingles on the face or near an eye, which needs same-day care to protect vision.
• Purple or dark spots that do not fade when pressed — this can signal bleeding under the skin and is an emergency-room sign.
• Swelling of the face or lips, or any trouble breathing — call 911; that is an allergic emergency, not a rash to monitor.

Many rashes can start with a photo and a video visit

Rashes are one of the better fits for telehealth: eczema flares, contact dermatitis, hives, and ringworm usually show their pattern clearly on camera, and treatment can often start the same day. As with every video visit, you must be physically in Texas at the time — and a self-pay video sick visit is the same $75 flat. A few photo habits make the visit work: take pictures in bright, natural light without filters, one close-up and one from farther back, with a clean coin in frame for scale if a spot's size matters. Our guide to what telehealth in Texas can and can't treat covers the full picture. And the limits from the urgent list still apply: a suspicious mole, a blistering rash, or redness spreading with fever needs eyes and hands in person, not a camera.

What the visit costs, and what to expect

A self-pay sick visit at Evolve Health is $75 flat — in person at 2442 Lillian Miller Pkwy, Suite 115 in Denton, or by video anywhere in Texas — told to you before you are seen, and including the exam, diagnosis, treatment plan, and prescriptions sent to your pharmacy when appropriate. If you have insurance, we verify your coverage free from your insurance card, photo ID, and date of birth before the visit, so you know where you stand first. We are open Monday–Friday, 7 AM–5 PM, with weekends by appointment, and we speak English, Nepali & Hindi.

Frequently asked questions

Can my primary care doctor check a mole, or do I need a dermatologist?

Your primary care doctor is a good first stop. We can examine a mole or spot up close, compare it against the ABCDE warning signs, document its size and appearance in your chart, and watch it over time. If a spot looks suspicious, we refer you promptly to a dermatologist, who can biopsy it — that procedure is the only way to know for certain what a spot is.

Does Evolve Health remove moles or do skin biopsies?

No. Evolve Health does not perform skin biopsies, surgical excisions, or cosmetic mole removal. What we do is examine the spot carefully, measure and document it, and — if it shows any warning signs — refer you promptly to a dermatologist who performs those procedures. Starting with us means the spot gets looked at this week instead of whenever a specialist's schedule opens up.

What is the ABCDE rule for checking moles?

ABCDE stands for Asymmetry (one half unlike the other), Border (edges irregular or blurred), Color (several colors or shades), Diameter (larger than about 6 millimeters, the size of a pencil eraser), and Evolving (any change in size, shape, color, or feel). It is a screening guide that flags spots worth an in-person look — not a diagnosis. A spot that checks none of the boxes can still deserve attention if it is new, changing, or simply looks different from your others.

Can a rash be handled over telehealth?

Often, yes. Many common rashes — eczema, contact dermatitis, hives, ringworm — can be assessed on a video visit with clear photos, as long as you are physically in Texas at the time. A self-pay video sick visit is the same $75 flat price. Some things still need an in-person visit: a suspicious mole, a blistering rash, a rash involving the eyes or mouth, or redness that is spreading with fever.

When is a rash an emergency?

Get urgent or emergency care for a rash with any of these: redness that is spreading along with fever, blistering or skin pain, involvement of the eyes, mouth, or lips, purple or dark spots that do not fade when pressed, or swelling of the face or lips or any trouble breathing. Shingles on the face or near an eye also needs same-day care. For breathing trouble or a rapidly spreading rash, call 911.

How much does a skin or rash visit cost without insurance?

A self-pay sick visit at Evolve Health is $75 flat — in person at our Denton clinic or by video anywhere in Texas — and the price is told to you before you are seen. It includes the clinician's exam, a diagnosis, a treatment plan, and prescriptions sent to your pharmacy when appropriate. If you have insurance, we verify your coverage free from your insurance card, photo ID, and date of birth before your visit.
