Abstract
We report here the first observation of phacomatosis pigmentokeratotica associated with nephroblastoma. In addition to this paediatric renal tumour, the coexistence of juvenile arterial hypertension suggests an associated vascular defect. The link between the extracutaneous manifestations and cutane...

Abstract
We present two rare cases of phacomatosis pigmentovascularis type IIb, with one patient demonstrating concurrent Sturge-Weber syndrome and Klippel-Trenaunay syndrome. To the best of our knowledge, this is the second infantile case meeting diagnostic criteria for systemic phacomatosis pigmentovascula...

Abstract
We describe the clinical and pathologic features of NCM in a 4.5-year-old female cynomolgus macaque. Histopathologically, skin lesions showed foci of nests and cords of pigmented cells in the dermis similar to blue nevi in humans. In the brain, focal pigmented cell infiltration was observed in the c...

Abstract
A combined hamartoma of the retinal pigment epithelium and the retina is a rare alteration of the ocular fundus. Knowledge of this mostly benign clinical picture is important to be able to differentiate it from malignant tumors such as choroidal melanoma. Occurrence in parallel with phacomatoses is...

Abstract
Speckled lentiginous naevus (synonym: naevus spilus) no longer represents one clinical entity, but rather, two different disorders can be distinguished. Naevus spilus maculosus is consistently found in phacomatosis spilorosea, whereas naevus spilus papulosus represents a hallmark of phacomatosis pig...

Abstract
We describe the first mutation in the human AP1S1 gene, encoding the small subunit sigma1A of the AP-1 complex. This founder splice mutation, which leads to a premature stop codon, was found in four families with a unique syndrome characterized by mental retardation, enteropathy, deafness, periphera...

Abstract
We discuss the major types of neurocutaneous disorders most frequently encountered by the neurosurgeon and followed beyond childhood. They include neurofibromatosis types 1 and 2, tuberous sclerosis, Sturge-Weber syndrome and von Hippel-Lindau disease. In each case, a review of the literature, inclu...

Abstract
Histologically, the pigmented tumor represented low grade. The pigmented dura and bone comprised melanin-bearing cells without tumor cells. Meningeal melanocytoma with leptomeningeal melanosis in the absence of cutaneous nevi was diagnosed. Neurologic symptoms recovered immediately after surgery. No...

Abstract
There are several rare syndromes combining wrinkled, redundant skin and neurological abnormalities. Although phenotypic overlap between conditions has suggested that some might be allelic to one another, the aetiology for many of them remains unknown. A consanguineous New Zealand Maori family has be...

Abstract
This new devasting, ultrastructural phenotype accompanied by apparently unspecific and mixed neurological symptoms should represent a future challenge to finally discover the pathogenesis of many childhood CNS symptoms, that currently seem to lack any apparent cause....

We describe a neonate with a nevus sebaceus on the scalp and a limbal dermoid on her left eye. Contiguous with the nevus sebaceus was a giant congenital melanocytic nevus and numerous areas of membranous aplasia cutis congenita. We propose the acronym SCALP (nevus sebaceus, central nervous system ma...

Abstract
We propose the new term "phacomatosis achromico-melano-marmorata". Future clinical research may show whether analogous "simple" twin-spot phenotypes in the form of "phacomatosis melanomarmorata" or "phacomatosis achromicomarmorata" do likewise exist....

We conclude that phacomatosis pigmentokeratotica may be associated with other cutaneous abnormalities such as linear connective tissue nevus of the collagen type and multiple pinhead-sized angioma-like lesions superimposed on the speckled lentiginous nevus. The associated defects of the large vessel...
