Is hypomelanosis of Ito the same as Incontinentia Pigmenti?
Hypomelanosis of Ito (HI), or pigmentary mosaicism, was previously named incontinentia pigmenti achromians. The disease is currently named hypomelanosis of Ito to distinguish this condition from incontinentia pigmenti.
How rare is hypomelanosis of Ito?
The incidence of hypomelanosis of Ito is estimated to be 1 in 8,000-10,000 people in the general population. The symptoms usually become apparent during the first or second year of life.
What is hypomelanosis of Ito?

What is Nevoid hypopigmentation?
Linear and whorled nevoid hypermelanosis (LWNH) is a rare disorder of pigmentation characterized by hyperpigmented macules in a linear or whorled streaky configuration. Lesions are distributed mainly on the trunk and extremities, sparing the palms, soles, and mucosae.
What is Achromic nevus?
Achromic naevus is an uncommon birthmark (naevus) characterised by a well-defined pale patch. This is usually several centimetres in diameter, with an irregular but well-defined border. Shape and size varies. Often, smaller hypopigmented macules arise around the edges, resembling a splash of paint.
How do you cure igh?
Idiopathic guttate hypomelanosis (IGH) is an acquired disorder presenting with small hypopigmented macules that occur chiefly on sun exposed regions of the skin. Treatments for IGH include corticosteroid, either topical or intralesional, topical retinoid, topical calcineurin inhibitors and surgical techniques.
Can Incontinentia Pigmenti be cured?
In most cases, IP is caused by mutations in a gene called NEMO (NF-kappaB essential modulator) which is involved in cell cycle regulation and programmed cell death. No cure has been found yet for IP.
Can Incontinentia Pigmenti fatal?
Incontinentia pigmenti (IP) is an X-linked dominant disorder and in males, is usually lethal before birth. In affected females, it causes highly variable abnormalities of the skin, hair, nails, teeth, eyes, and central nervous system.
What is the difference between hypopigmentation and depigmentation?
In hypopigmentation, pigment is decreased, whereas in depigmentation, pigment is completely lost, leaving white skin.
What is the difference between hyperpigmentation and hypopigmentation?
Simply put, hyperpigmentation is the problem of having too much pigmentation in an area of the skin while hypopigmentation is having too little. The former usually presents itself on the face as an excess of melanin in dark spots on any area of the body – though it usually is most prominent when it appears on the face.
How can you tell the difference between nevus depigmentosus and vitiligo?
Lesions in vitiligo are depigmented, whereas lesions in nevus depigmentosus are hypopigmented. Furthermore, the distribution of vitiligo is symmetric, with predilection for the face and areas subject to repeated friction, such as hands, feet, and genitals.
What is nevus Anemicus?
Nevus anemicus is an uncommon, congenital vascular malformation resulting in hypopigmented cutaneous macules and/or patches that characteristically do not become erythematous in response to trauma, heat, or cold. Nevus anemicus typically presents as an isolated lesion with no other systemic manifestations.
Is IGH permanent?
If you need more reasons to never skip sunscreen, here’s another one for you: white freckles or idiopathic guttate hypomelanosis (IGH). “You cannot get this color back. The spots are permanent,” warns Dr. Shainhouse.
