Orphanet: Lipoid proteinosis

Extracellular matrix protein 1 gene ECM1 mutations in lipoid proteinosis and genotype-phenotype correlation. Clinical description A wide range of clinical signs is noted and disease severity is variable, while the course is usually slowly progressive.

The prognosis is generally favorable. They may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the proteinosiis around the eyelids.

After 6 months, improvement of cutaneous lesions was not satisfactory, but there was significant improvement of hoarseness. Sign up for our Email Newsletters. Biopsy of affected skin showed deposition of neutral mucopolysaccharides. Although the outcome with cutaneous lesions was not satisfactory, her hoarseness was proteniosis improved.

The deposits seen in lipoid proteinosis are: Lipoid proteinosis in two siblings: Rao AG, Koppada D.

It also allows doctors to better distinguish between Urbach—Wiethe disease and other similar diseases not caused by mutations in ECM1.


Unfortunately, it is not free to produce. Case of the Week Beaded papules over bilateral eyelids.

Lipoid proteinosis

From a study of this unusual patient, Adolphs et al. Retinoids are proposed to modulate the metabolism of basement membrane [ 28 ]. Brain CT scan showed bilateral symmetric calcification in the medial temporal lobe in the region of the amygdala. Extensive atrophic scars, glossy, infiltrated, yellow papules, and plaques were present on her forehead and cheeks Figures 1 a and 1 b and lipooid papules on the margins of the upper eyebrows Figure 2 a.

In this paper lipois describe a year-old LP patient who was treated with acitretin for six months. In addition, she had a history of weak cry during infancy and hoarseness since birth.

Genealogy of lipoid proteinosis.

The discovery that the loss of ECM1 expression leads to the symptoms associated with Urbach—Wiethe disease suggests that ECM1 may contribute to ptoteinosis adhesion, epidermal differentiation, and wound healing and scarring. Initial scarring had begun on her face six years ago and then progressed to her shoulders and arms. Disease definition Lipoid proteinosis LP is a rare genodermatosis characterized clinically by mucocutaneous lesions, hoarseness developing in early childhood and, at times, neurological complications.

LP is caused by deposition of an amorphous hyaline material in the skin, mucosa, and viscera. Chromosome 1, where the ECM1 mutation occurs at 1 q Patients with lipoid proteinosis have a normal life expectancy However, deposits in the larynx can lead to airway obstruction and may need to be ablated. The oral mucosa is often involved with cobblestone lips, tongue or gingiva, impaired tongue mobility causing proteinksis problems, and transient swelling and ulceration of the lips and tongue.


Acitretin Treatment for Lipoid Proteinosis

Causative loss-of-function mutations have been found in the ECM1 gene 1q21 encoding extracellular matrix protein 1, which has a role in physiology and homeostasis of the skin and many other tissues. Some other dermatological symptoms that are sometimes seen but less common include hair lossparotitis and other dental abnormalities, corneal ulceration, and focal degeneration of the macula.

Acta Derm Venereol ; A founder effect is reported among large kindreds in South Africa. Using a candidate gene approach, Hamada et al. Lipid-proteinosis Urbach-Wiethe involving the lids. There is currently no known effective curative treatment and no standard treatment approach. Physical examination showed acneform facial lesions and scarring, with fine nodules along the palpebral fissures.

Br J Dermatol ; It was first described in [ 1 ] by the Viennese dermatologist Urbach and otorhinolaryngologist Wiethe and named after the histological findings, which was thought to reflect abnormal protein and lipid deposition in various tissues.
