The Dark Band the Client Wants Covered
A 58-year-old new client books a gel manicure. While prepping, you see a brown-to-black band about 4 mm wide running the full length of the left thumbnail, from the cuticle to the free edge, with fairly sharp borders. The nail plate is otherwise smooth, and the surrounding skin looks normal to you. She mentions it has been there "maybe five months" and that she assumed it was a bruise from gardening, though she cannot recall an injury. She also mentions her father had a skin cancer removed from his face. She has brought a photo of a deep espresso-brown gel color and asks you to "make it disappear" because she has a reunion in two weeks.
1. What about this presentation should raise concern, and what can and cannot you do about it?

What raises concern:
- A single, well-defined longitudinal brown-black band on one nail in a person over 50, present for months and not resolving, is the classic presentation that must be evaluated for subungual melanoma. Benign causes exist - melanonychia in darker skin tones, trauma, medication effects, a benign nevus - but you cannot distinguish them by eye.
- Duration and lack of trauma history argue against a bruise. A subungual hematoma grows out with the nail and usually has a history of injury.
- Family history of skin cancer is an additional risk factor.
- Signs that would be even more urgent: pigment spreading onto the cuticle or lateral fold (Hutchinson's sign), splitting or distortion of the plate, or a mass under the free edge.
What you cannot do: diagnose it. Not melanoma, not fungus, not a bruise. Saying "that's just a bruise" is the single most dangerous thing you can say here, because it can delay diagnosis by months.
What you can do: perform a manicure with opaque polish or gel if the client chooses, with these limits - do not abrade, cut, or push aggressively into the area; do not apply product if the plate is broken or the fold is inflamed; do not promise coverage will not affect her decision to get it checked. Your job is to refer clearly and document.
2. Script the conversation with the client and explain the reasoning behind each part of it.

The conversation, in order:
- Describe, don't diagnose. "I want to point out something on your left thumb. There's a brown band that runs the whole length of the nail, and you said it's been there about five months without an injury you remember."
- Explain why you're raising it. "Most dark bands are harmless, but a band like this that shows up in one nail and doesn't grow out is something a doctor should look at, just to be sure. I'm not able to tell you what it is - that's not my training."
- Make the referral concrete. "I'd like you to show it to your primary care provider or a dermatologist. If you want, I can note in your file what I saw and when, so you have dates."
- Answer her real question - the polish. "I can absolutely do your gel color today. The color will hide it while it's on, but I don't want the polish to be the reason you put off getting it checked."
- Do not argue if she declines. Document that you advised evaluation and she declined. Do not re-diagnose later in the appointment.
Reasoning behind the wording:
- "Most are harmless" keeps you truthful and non-alarming; "a doctor should look" is a referral, not a diagnosis.
- Naming the referral destination removes the excuse that she didn't know who to see.
- Offering the service she came for keeps the relationship and avoids the client feeling lectured - but the documentation of the referral is the non-negotiable part.
- If she pushes you to say what it is, repeat: "I can't tell you that. I can tell you it should be looked at."
3. The client says, "If it were serious, wouldn't it hurt?" How do you respond, and what goes in the record?
Read the worked answer
Response: "Not necessarily. A lot of serious nail and skin findings don't hurt at all, especially early on - that's exactly why they're easy to ignore. Pain isn't a reliable test, and I'd rather you get one appointment with a doctor than wait to find out."
Why: the absence of pain is a common and dangerous reason clients delay care. You are not making a diagnosis; you are explaining why symptoms are a poor rule-out tool.
Record entry:
- Date; "New client, gel manicure."
- "Left thumb: longitudinal brown-black band, approx. 4 mm, cuticle to free edge, sharp borders; plate intact; periungual skin unremarkable on visual inspection. Client states present ~5 months, no known trauma. Family history of skin cancer reported by client."
- "Advised client to have area evaluated by primary care or dermatology; client stated 'if it were serious it would hurt.' Reinforced that absence of pain does not rule out serious causes. Client acknowledged."
- "Gel manicure performed; no abrasion or product applied to any broken skin. Client to follow up with provider."
- Initials and time.
Why this level of detail: if the finding later turns out to be significant, the record shows you observed it, described it objectively, referred appropriately, and did not reassure her that it was benign. That is the difference between a defensible chart and an indefensible one.
