Is this 4-year-old female child suffering from a forme fruste of hypomelanosis of Ito?

Abstract

Hypomelanosis of ito (HI) is a multisystemic disorder characterized by cutaneous, neurologic disorder, and musculoskeletal disorder. However, there may be isolated cutaneous manifestation, resulting in diagnostic overlap with other hypopigmentary lesions such as nevus depigmentosus and hypopigmentation along the lines of Blaschko. Therefore, there is the need for generally acceptable diagnostic criteria avoiding these ambiguities. Hence, the case of a 4-year-old female child with isolated hypopigmentations characterized as whorls on the torso and as linear distribution along the lines of Blaschko is reported.
