Pigmentation Disorders Compared: Insight into Albinism and Vitiligo

Pigmentation disorders affect the production or distribution of melanin, the pigment responsible for the color of human skin, hair, and eyes. Among these disorders, albinism and vitiligo are two conditions that result in reduced or absent pigmentation but arise from very different biological mechanisms. Albinism is a congenital genetic disorder caused by mutations in genes involved in melanin synthesis, leading to generalized hypopigmentation and often associated visual abnormalities. In contrast, vitiligo is an acquired autoimmune condition in which the immune system targets and destroys melanocytes, resulting in patchy depigmentation that typically develops later in life. This review paper compares etiology, pathogenesis, clinical features, differential diagnosis, and treatment approaches of both conditions, highlighting the key similarities and differences between them. Understanding these distinctions is essential for accurate diagnosis, effective clinical management, and reducing common misconceptions surrounding pigmentation disorders in diverse populations.
