Presentation
Sacral pits associated with pink plaques were present in 2 patients, verrucae vulgaris were present in 2 patients, and another presented with molluscum contagiosum. [jamanetwork.com]
Vertebral anomalies and conductive hearing loss were present with less frequency. Some characteristics considered typical of this condition (jaw cementomas, acanthomas and finger abnormalities) were absent in most of the patients. [scienceopen.com]
We report on an infant who presented at birth with multisuture synostosis, turribrachycephaly, midface hypoplasia, beaked nose, low set ears, a high palate and short squat appearing thumbs, and great toes without deviation. [onlinelibrary.wiley.com]

Workup
Although the patient was receiving metformin treatment for insulin resistance, she had not undergone any prior workup to identify a unifying syndromic cause for her physical and biochemical findings. [mdedge.com]
Clinical Testing and Workup CT scanning and MRIs are used to help detect or characterize certain abnormalities that may be associated with the disorder (e.g., craniosynostosis, other skeletal abnormalities, etc.). [rarediseases.org]

However, any improvement seen was lost after discontinuation of the treatment. [jamanetwork.com]
Further treatment involves multidisciplinary control and coordination by the Copenhagen Craniofacial Unit. Midface distraction will be performed at 7–10 years of age. [ncbi.nlm.nih.gov]
Prognosis
Thus, the prognosis of Acanthosis Nigricans is excellent with adequate (skin) treatment. [dovemed.com]
The severity of the cranial bone deformations, associated systemic abnormalities and age of diagnosis may yield variable treatment outcomes and overall prognosis [6]. [eyewiki.aao.org]
Prognosis depends on the severity of malformations. Innovations in craniofacial surgery have enabled patients to achieve their full potential by maximizing their opportunities for intellectual growth, physical competence and social interaction. [scialert.net]
Etiology
Etiology CAN is caused by a specific p.Ala391Glu mutation in the fibroblast growth-factor receptor 3 FGFR3 gene (4p16.3), involved in regulation of cell proliferation, differentiation and apoptosis. [orpha.net]
The etiology of acanthosis nigricans is variable and can be one of the following: - Hereditary with dominant autosomal transmission. - Associated with genetic abnormalities or endocrine diseases. - Pseudo-acanthosis nigricans resulting from complications [scielo.br]

Pathophysiology
Pathophysiology Dysplasias of the skeleton (including craniofacial dysostosis) are caused by the malformations of the mesenchyme and ectoderm. The unknown teratogenic factors are taken into account. [emedicine.medscape.com]
The presence of hydrocephalus in 11 of 23 patients with JFA or JFS (Groups 1–3) supports the importance of venous hypertension as a pathophysiologic mechanism in the development of hydrocephalus in patients with craniosynostosis (15). [ajnr.org]

This early fusion prevents the skull from growing normally and affects the shape of the head and face. Crouzon syndrome is seen in about 1 per 60,000 newborns. It is the most common craniosynostosis syndrome. [cranioutah.com]
This early fusion prevents the skull from growing normally and affects the shape of the head and face. Many features of Crouzon syndrome result from the premature fusion of the skull bones. [craniofacialmd.com]
Prevention : Since it is a genetic defect which causes abnormal mutations on Chromosome 10, there is nothing much that you can do to prevent it. [diseasesdoctor.com]
