Differential Diagnoses
| Addison Disease | Vitiligo |
| Albinism | Vogt-Koyanagi-Harada Syndrome |
| Alezzandrini Syndrome | Waardenburg Syndrome |
| Leprosy | Yaws |
| Skin Lightening and Depigmenting Agents | |
| Systemic Sclerosis | |
| Tinea Versicolor |
Other Problems to Be Considered
Chemical leukoderma
Onchocerciasis
Preus syndrome
Pinta
Vitiligo (distinguished by the presence of lesions from birth, hyperpigmented macules of depigmented and normal skin, and static course)
Yaws (frambesia tropica)
Ziprkowski-Margolis syndrome
A screening program to detect Waardenburg syndrome among 1763 deaf individuals throughout Colombia identified 95 affected individuals belonging to 95 families, giving a frequency of 5.38% of Waardenburg syndrome among the institutionalized deaf population.9 Overall, among the 95 propositi, the most frequent features were broad nasal root (58.9%), a first-degree relative affected (37.9%), heterochromia irides (36.8%), skin hypopigmentation (31.6%), white forelock (28%), intense blue iris (27.4%), synophrys (12.6%), premature graying (10.5%), ptosis of the eyelids (9.5%), and hypoplasia alae nasi (1.1%).
