The management of laryngeal lipoid proteinosis

BackgroundLipoid proteinosis is a rare autosomal recessive disorder caused by mutations in the extracellular matrix protein 1 gene. It is characterised by deposition of hyaline material in the skin and mucous membranes. This paper describes the management of two cases with laryngopharyngeal disease.MethodsTwo patients with a biopsy diagnosis of lipoid proteinosis were identified from the surgical pathology archive covering the period 2004–2016. Their notes were reviewed.ResultsAn adult male and an adult female were identified. Both had dysphonia and laryngopharyngeal lesions. The patients underwent interval laser microlaryngoscopy to debulk disease but minimise mucosal injury and scarring, using a ‘pepper pot’ technique. Both had adequate symptom control.ConclusionLipoid proteinosis is a rare genetic condition, which typically presents in infancy with dysphonia and subsequent skin involvement. Two cases are presented to demonstrate that laryngotracheal symptoms can be controlled with interval laser debulking and the ‘pepper pot’ technique without causing stenosis.
