Oral Manifestations and Dental Management Considerations of Lipoid Proteinosis: A Case Report and Review of Literature

Lipoid proteinosis (LP) is a sporadic congenital metabolic disorder characterized by deposition of hyaline material in various organs. It has a very low prevalence rate of approximately 300 cases reported up to now. It has a vast spectrum of manifestations ranging from asymptomatic skin lesions to the rare but life-threatening laryngeal obstruction. The knowledge of the clinical features of the disease such as hoarseness of voice from infancy, mucocutaneous manifestations, moniliform blepharosis (multiple, beaded papules along the eyelash line) and dental anomalies such as hypoplasia or aplasia of teeth may help oral health care practitioners improve the quality of their patient's life. This case report describes a typical 10-year-old boy who presented to the Department of Pediatric Dentistry, Faculty of Dentistry, University of Medical Sciences, Kerman, Iran with the typical recurrent skin and mucosal lesions, hoarseness, and blepharosis. In addition, he stated a gradual hearing loss, which is not reported as a common manifestation. Moreover, psychosocial issues regarding his appearance and quality of voice had led to absenteeism from school. A punch biopsy obtained from a lesion on his forearm revealed the characteristic histopathological view and directed to the diagnosis of lipoid proteinosis. Dental treatment was initiated with focus on preventive dentistry due to the restricted mouth opening, which was expected to get worse overtime. There is no definitive cure for this disease and the treatment is symptomatic in most cases. A proper workup can result in early diagnosis and management of dental complications, which are difficult to control due to restricted mouth opening, which may significantly affect the patient's social life.

A novel association of the additional intracranial calcification in lipoid proteinosis: a case report

Lipoid Proteinosis (LP) is a genetically linked, autosomally transferred, rare, chronic multisystem disease which is characterized by a normal lipid profile, but with abnormal deposits of lipids and proteins in the body, which slowly but steadily leads to systemic manifestations. Although it affects almost all the systems of the body, it predominantly manifests as lesions on the skin and it has characteristic intracranial calcifications. Although, the intracranial calcifications can be classified, based on their aetiopathogenesis, as agerelated and physiologic, congenital, infectious, endocrine and metabolic, vascular, and neoplastic; the symmetric calcifications in LP are a distinct entity. To one who is aware of this entity, LP is usually an incidental diagnosis. No permanent cure is available for LP till date. Only symptomatic medical treatment is being given. With the increasing awareness on this entity, LP can now be detected in its early phase and it can be better managed.As this condition is rare, it is necessary to spread awareness on this entity in the scientific community and hence this case is being reported. This case report is the first to demonstrate a novel association of an additional intracranial calcification in Lipoid Proteinosis.

Molecular analysis of lipoid proteinosis: identification of a novel nonsense mutation in the ECM1 gene in a Pakistani family

Lipoid proteinosis is a rare autosomal recessive disease characterized by cutaneous and mucosal lesions and hoarseness appearing in early childhood that is caused by homozygous or compound heterozygous mutations in the ECM1 gene located on chromosome 1q21. The aim of the study was to investigate the molecular genetic defect underlying lipoid proteinosis in a consanguineous Pakistani family.
