Can a dark toe spot in a 39-year-old woman indicate cancer?

Question

Hello doctor,

I am a 39-year-old female with a past medical history of sinusitis, nasal polyps, and anxiety. I currently take a nasal steroid and Cetirizine. I developed a small brown spot on my toe five months ago. I am concerned because it has grown larger and is now about 1.5 mm. There is no itching or bleeding, but it does look dark.

I am worried because I read that a rapid change in size can indicate malignancy, and I do not know what normal growth is. I have made an appointment with dermatology, but the earliest available date is in two months.

Is this too late, and should I book an urgent appointment?
What is your opinion based on the pictures?

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

I have carefully reviewed the photo and your medical history. The spot on your toe appears to be a small pigmented lesion about 1.5 mm in size. It is reassuring that there is no bleeding, pain, or itching, and the color looks even and well defined.

However, your concern is valid because any new pigmented lesion on the toes or nails that changes in size or appearance should be monitored closely. Most small spots like this are benign, like freckles, moles, or post-inflammatory pigment. Still, dermatologists are cautious with new growths on the toes since rare conditions can occur. The fact that it has grown, even slowly, justifies getting it checked.

Since your dermatology appointment is in two months and the lesion is tiny, a short delay is usually not dangerous, even if it is something concerning. If the spot grows rapidly, becomes irregular in shape, develops multiple colors, bleeds, or ulcerates, you should request an urgent appointment rather than wait.

In the meantime, take a clear photo in good lighting every two to three weeks to document any changes.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
