Hypomelanosis of Ito Incontinentia pigmenti achromians; HMI; Ito hypomelanosis. Common symptoms reported by people with hypomelanosis of Ito Volume 9, Issue 1. Hypomelanosis of Ito is a skin disorder characterized by hypopigmentation in the pattern of streaks, whirls, and mottled patches of light-colored skin. Pages 1-10. Etiology. Hypomelanosis of Ito (HMI) is a very rare birth defect that causes unusual patches of light-colored (hypopigmented) skin and may be associated with eye, nervous system, and skeletal problems. The etiology of hypomelanosis of Ito remains mysterious. Hypomelanosis of Ito is a clinically well-characterized syndrome in which chromosomal instability may be a component. Related; Information; Close Figure Viewer. Hypomelanosis of Ito is a neurocutaneous disorder characterized by skin manifestations in a characteristic pattern associated with musculoskeletal and central nervous system symptoms. The old name, incontinentia pigmenti achromians, implies an association with incontinentia pigmenti (IP) and was probably used because hypomelanosis of Ito appears to be the negative image of incontinentia pigmenti. March 1992. Abnormalities of other organ systems are often seen in conjunction with the skin findings, particularly the central nervous system. A 22 year old woman presented with a history of uncontrolled generalised tonic clonic seizures and myoclonic jerks since the age of 2 years. BACKGROUND: Hypomelanosis of Ito is a rare genetic disorder characterized by whorled areas of hypomelanosis. The skin markings in the lightly pigmented individual are not easily visualized in regular light but can be readily seen with the use of Wood's light. Hypomelanosis of Ito. Pascual-Castroviejo I(1), Roche C, Martinez-Bermejo A, Arcas J, Lopez-Martin V, Tendero A, Esquiroz JL, Pascual-Pascual SI. Hypomelanosis of Ito is currently a descriptive rather than definitive diagnosis. Hypomelanosis of Ito, also known as incontinentia pigmenti achromians, is a rare disorder characterized by a whorled pattern of light patches on the skin. Hypomelanosis of Ito (HI) is characterised by hypochromic unilateral skin lesions, hemi‐hypertrophy, mental retardation (MR) and seizures. It is characterized by linear nevoid hypopigmentation along the lines of Blashko located on the limbs and the trunk. Methods Clinical observations included ultraviolet‐light‐enhanced visualization (ULEV) method. Criteria for its presumptive and definitive diagnosis are proposed. a congenital neurocutaneous syndrome, not present at birth but appearing in early life, characterized by whorled, linear, and splatterlike patterns of hypopigmentation, often associated with other abnormalities such as hair loss and ocular,… Alerts and Notices Synopsis Hypomelanosis of Ito (incontinentia pigmenti achromians) is not a distinct entity, but rather a manifestation of many different states of somatic mosaicism displaying in the skin with "whorls" of hypopigmented skin patches. Skin lesions usually develop in early infancy and remain unchanged through childhood and beyond. Citing Literature. The clinical pattern is characterized by hypopigmented streaks and whorls running along the lines of Blaschko, characteristically involving more than two body segments. Hypomelanosis of Ito (HMI) is a very rare birth defect that causes unusual patches of light-colored (hypopigmented) skin and may be associated with eye, nervous system, and skeletal problems. Data from.prior case reports in the world's literature are also reviewed. 1 We describe a young woman with HI with interesting and hitherto unreported magnetic resonance imaging (MRI) changes. The skin lesions is believed to be genetically determined. Assogba, K, Ferlazzo, E, Striano, P. “Heterogeneous seizure manifestations in hypomelanosis of Ito: report of four new cases and review of the literature”. Hypomelanosis of Ito is a pigmentary mosaicism characterized by a clone of skin cells with decreased ability to produce pigment.

These skin changes often develop within the first two years of life. Background Hypomelanosis of Ito is a rare genetic disorder characterized by whorled areas of hypomelanosis. Hypomelanosis of Ito, also named incontinentia pigmenti achromians in the past, is a rare neurocutaneous syndrome described by Ito in 1952 , and characterized by hypopigmented lesions occurring in streaks and whorls located on the trunk, head, or extremities.
