Macule

2025-09-30 🇷🇴 Română

What is it?

A macule is a flat spot on the skin that looks different in color from the surrounding skin but feels completely smooth when you touch it. Think of it like a stain on fabric - you can see it but can't feel it with your eyes closed. Macules are typically smaller than a pencil eraser (less than 1 centimeter) and can be various colors including brown, white, red, or purple.

What does it look like?

Macules appear as:

  • Flat spots that are level with the skin surface
  • Size of a pinpoint up to a pencil eraser (less than 1 cm)
  • Various colors: brown (freckles), white (vitiligo), red (flat birthmarks), tan (café-au-lait spots)
  • Smooth texture - no roughness, scaling, or elevation
  • Clear or fuzzy borders depending on the cause
  • Single spots or multiple spots that may cluster together

Where does it appear?

Macules can appear anywhere on the body:

  • Face: Freckles, age spots, melasma
  • Trunk and back: Café-au-lait spots, drug reactions
  • Arms and legs: Vitiligo, post-inflammatory color changes
  • Sun-exposed areas: Solar lentigines (age spots)
  • Anywhere: Flat moles, medication reactions

Associated features

Macules may occur with:

  • No symptoms at all (most common)
  • Multiple similar spots in the same area
  • Gradual color changes over time
  • Darkening with sun exposure (brown macules)
  • Family members with similar spots
  • Other types of skin lesions if part of a rash

When to see a doctor

Seek medical evaluation for:

  • New dark spots that appear suddenly
  • Macules that change color, size, or shape
  • Multiple café-au-lait spots (could indicate genetic condition)
  • White patches that are spreading
  • Red or purple spots that don't fade with pressure
  • Any concerning changes in existing spots
  • Macules accompanied by other symptoms like fever
