A recent and novel method of melanoma detection is the "Ugly Duckling Sign". It is simple, easy to teach, and highly effective in detecting melanoma. Simply, correlation of common characteristics of a person's skin lesion is made. Lesions which greatly deviate from the common characteristics are labeled as an "Ugly Duckling", and a dermatologist exam is required. The "Little Red Riding Hood" sign suggests that individuals with fair skin and light colored hair might prove more challenging. These fair-skinned individuals often have lightly pigmented or amelanotic melanomas which will not present with easy to observe color changes and variation in colors. The borders of these amelanotic melanomas are often indistinct, making visual identification without a dermatoscope (dermatoscopy) very difficult. A dermatoscope must be used to detect "ugly ducklings" among those with light skin or blonde/red hair.
