From 40% to 60% of patients with hypomelanosis of Ito will have structural brain abnormalities or mental retardation with or without seizures.
If hypomelanosis of Ito is suspected because of skin lesions but the child is meeting developmental milestones, there's no need to do a genetic work-up for this disorder, she said.
Progressive macular hypomelanosis, hypopigmented macules, narrow-band ultraviolet B.
Progressive macular hypomelanosis (PMH) is an uncommon skin disorder characterized by ill-defined nummular, non-scaly hypopigmented confluent macules on the trunk, often in and around the midline, and rarely extending to the proximal extremities and neck/head region.
The term hypomelanosis of Ito is applied to individuals with skin hypopigmentation along the lines of Blaschko.
Thus, despite current lack of a definitive genetic explanation, it has been suggested that HI is not a single condition, but a rather nonspecific manifestation (ie, a phenotype) of different chromosomal mosaicism and that the term hypomelanosis of Ito should now be dropped.
5] The common pigmentary disorders encountered were idiopathic guttate hypomelanosis
Idiopathic guttate hypomelanosis was present in 99 (33%) cases in this study.
