Incontinentia pigmenti achromians is a multisystem hereditary disorder characterized specifically by a whorled or streaked cutaneous hypopigmentation and frequently characterized by numerous neurologic, musculoskeletal, and ocular abnormalities. We present a patient with incontinentia pigmenti achromians in whom the ocular abnormalities included the commonly reported exotropia, myopia, small optic nerve, and hypopigmentation of the fundus, as well as rarely reported corneal asymmetry, pannus, and atropic irides with irregular pupillary margins. The patient also had a cataract in the right eye and a retinal detachment in the left eye.

Hypomelanosis of Ito (incontinentia pigmenti type I) was first described as a disorder characterized by unusual unilateral or bilateral cutaneous macular hypopigmented whorls, streaks and patches. Subsequently, neurologic, skeletal and ocular involvement were described. Kidney involvement has been reported only exceptionally. Here, we describe the case of a male infant with hypomelanosis of Ito with a prenatal diagnosis of bilateral enlargement of the kidneys, decreased corticomedullary differentiation and cysts located in the cortical and subcapsular regions. These findings were confirmed postnatally. The skin examination showed hypopigmented linear and round diffuse lesions located on the right leg and the arms. Ophthalmological examination showed anterior capsular and posterior subcapsular cataract of the left eye. Renal biopsy was characteristic of glomerulocystic kidney disease, whereas the skin biopsy confirmed the clinical diagnosis of hypomelanosis of Ito. Four other cases of kidney disease in hypomelanosis of Ito have been reported, including two cases characterized by cystic renal changes, indicating that gene abnormalities that cause hypomelanosis of Ito may also impair normal renal development, causing renal cystic changes.

A 10-year-old boy presented with a severe and diffuse mosaic skin hypopigmentation running (in narrow bands) along the lines of Blaschko associated with mosaic areas of alopecia, facial dysmorphism with midface hypoplasia, bilateral punctate cataract, microretrognathia, short neck, pectus excavatum, joint hypermobility, mild muscular hypotonia, generalized seizures, and mild mental retardation. Cranial magnetic resonance imaging revealed hypoplastic corpus callosum (primarily posterior), subcortical band heterotopia, and diffuse subcortical, periventricular cystic-like lesions. Similar dysmorphic features were observed in the child's mother, but with no imaging abnormalities. The facial phenotype coupled with the cysts in the brain was strongly reminiscent of the oculocerebrorenal Lowe syndrome. Full chromosome studies in the parents and the proband and mutation analysis on peripheral blood lymphocytes (and on skin cultured fibroblasts from affected and unaffected skin areas in the child) in the genes for subcortical band heterotopia (DCX (Xq22.3-q23)], lissencephaly (PAFAH1B1, alias LIS1, at 17p13.3), and oculocerebrorenal syndrome of Lowe (OCRL at Xq23-q24)] were unrevealing. This constellation of multiple congenital anomalies including skin hypopigmentation and eye, musculoskeletal, and nervous system abnormalities was sufficiently characterized to be regarded as a novel example of pigmentary mosaicism of the Ito type (i.e., hypomelanosis of Ito).
