Mammary gland is composed of branched epithelial structure embedded within a complex stroma formed by several stromal cell types, including fibroblasts, and extracellular matrix (ECM). Development of mammary gland is tightly regulated by bidirectional epithelial-stromal interactions that include paracrine signaling, ECM remodeling and mechanosensing. Importantly, these interactions play crucial...
Here we report a boy with epidermal nevus syndrome associated with brainstem and cerebellar malformations and neonatal medulloblastoma. The patient had epidermal nevi and complicated brain malformations including macrocephaly with polymicrogyria, dysmorphic and enlarged midbrain tectum, enlarged cerebellar hemispheres with small and maloriented folia. The patient died after surgical resection o...
Nevus comedonicus is an uncommon skin abnormality characterized by an aggregation of dilated follicular orifices filled with keratinous material. Nevus comedonicus is occasionally complicated with other conditions including cataracts, skeletal defects, central nervous system abnormalities or other extra-cutaneous diseases (nevus comedonicus syndrome). Although most cases of nevus comedonicus oc...
The case of a left handed girl aged 18 years suffering from the "epidermal maevus syndrome" is described. She presented with dysphasia, transient left hemiparesis, and sensory symptoms due to an occlusion of the right internal carotid artery. Arterial occlusion, abnormal retinal vessels, and Raynaud's phenomenon have not been previously documented. The neurological complications of this syndrom...
First Reported Case of 'Epidermal Nevus Syndrome' with a Triad of Central Nervous System Deformities
Epidermal nevus syndrome (ENS) is a term used to describe the occurrence of an epidermal nevus in association with other extra-cutaneous developmental anomalies, most commonly involving the nervous and musculoskeletal systems. The nevus is classified on the basis of the main component which may be keratinocytic, sebaceous, follicular, apocrine, or eccrine. Most patients who present with ENS is ...
Agenesis of Bilateral Internal Carotid Arteries in the PHACE Syndrome We read with interest the paper by Weon et al, in which they described the case of a 14-year-old girl with a complex association of agenesis of the bilateral internal carotid arteries with transcranial collaterals from the external carotid artery, agenesis of the vertebrobasilar system, hypoplasia of the right cerebellar hemi...
RATIONALE Linear nevus sebaceous syndrome (LNSS) is a rare neurocutaneous syndrome, characterized by nevus sebaceous,central nervous system (CNS), ocular and skeletal abnormalities. The present study describes KRAS somatic mosaic mutation in a case of LNSS with lymphatic malformations (LMs). PATIENT CONCERNS A 4-month-old female with a clinical diagnosis of LNSS presented with infantile spasm...
Epidermal Nevus Associated with Cerebral and Ocular MR Imaging Abnormalities This letter focuses on Schimmelpenning syndrome (SS), a neurocutaneous disorder related to epidermal nevus syndromes and characterized by craniofacial nevus, neurologic anomalies, and ocular pathology. We discuss clinical and MR imaging features of a 10-year-old boy, pointing out the etiopathologic substratum of this c...
Epidermal nevus syndrome (ENS) is a rare condition characterized by congenital epidermal nevi (EN) associated abnormalities of other organs including central nervous system (CNS), skeletal system, eyes, and oral cavity (1). ENS is divided into a group of distinct disorders, based on the associated epidermal nevus and genetic inheritance pattern. Organoid nevus could be seen in some ENS, includi...
New developments in instrumentation for ocean environmental engineering are allowing unprecedented levels of trace contaminant measurement in the deep ocean. With funding from the U.S. National Science Foundation (NSF), our engineering design team constructed a new mass spectrometerbased in situ analysis system for work in the deep ocean environment over prolonged deployment periods. Our design...
