Lipoid Proteinosis

Urbach-Wiethe Disease


Presentation

  • We present four patients with lipoid proteinosis involving skin, oropharynx and larynx.[ncbi.nlm.nih.gov]
Collapse
  • Ultrastructure (EM) revealed highly ordered matrix deposits around microvessels, with frequently collapsed lumina, functionally compensated by increased vascular density (histology, IIF).[ncbi.nlm.nih.gov]
Macroglossia
  • Additional symptoms included beaded eyelid papules, macroglossia with yellowish papules, yellowish deposits of soft palate, papular eruption in the axillary area and tuberous nodules on the elbows.[histopathology-india.net]
  • […] amyloidosis Hyperpigmented papulonodular eruptions occur, especially on the shins and upper limbs that may coalesce into thickened plaques A skin biopsy with Congo red stain helps in making the diagnosis Xanthomatosis Myxoedema hoarseness of voice, macroglossia[slideshare.net]
  • Physical examination revealed an otherwise healthy man with macroglossia, yellowish deposits on the tongue and soft palate, beaded papules on the thickened margins of the eyelids, yellowish papules in the axillae and nodules of variable sizes on both[medicaljournals.se]
  • Lateral surface of his tongue showed clear indentations of the dentition, indicating macroglossia. The tongue was firm and woody in consistency, with no fibrotic bands on palpation.[jdrntruhs.org]

Cutis Laxa
  • Abstract There has been progress made in the understanding of 3 Mendelian disorders: pseudoxanthoma elasticum, cutis laxa, and lipoid proteinosis cutis and mucosae.[ncbi.nlm.nih.gov]
  • Typical patients have hyperextensible skin ( Fig. 137-1 ) that recoils easily to its normal position after stretching, in contrast to the skin in cutis laxa (CL).[plasticsurgerykey.com]

Personality Change
  • CONCLUSIONS: These individuals illustrate the neurologic spectrum of LP, including variable mental retardation, personality changes, and mesial temporal calcificationand imply that significant neurologic involvement may be somewhat less common than previously[ncbi.nlm.nih.gov]

Workup

Human Papillomavirus
  • Epidermodysplasia verruciformis (EV) is also a rare autosomal recessive genodermatosis involving susceptibility to human papillomavirus (HPV) infections and squamous cell carcinoma, caused in most cases by homozygous mutations in EVER1 or EVER2.[ncbi.nlm.nih.gov]

Treatment

  • Previous research on treatment of lipoid proteinosis has focused on genetic etiology and clinical diagnosis of this rare laryngeal disorder. However, few studies on this disorder have examined treatment methods directed at improving voice qualities.[ncbi.nlm.nih.gov]

Prognosis

  • KEYWORDS: ECM1 gene mutation; epilepsy; ictal EEG; lipoid proteinosis; prognosis[ncbi.nlm.nih.gov]
  • The prognosis of lipoid proteinosis is generally good although, the disease is progressive until early adult life. [6] Almost every organ of the body is involved.[e-ijd.org]
  • Prognosis •Lipoid proteinosis has a stable or slowly progressive course •The presence of this disease is compatible with a normal life span unless altered by airway obstruction or fatal seizure activity •Mortality rates in infants and adults are slightly[slideshare.net]
  • The overall prognosis is good. There is no definitive treatment.[idoj.in]

Etiology

  • Etiology and pathogenesis are unknown. Infantile hoarseness is a common presenting feature of the disease due to infiltration of larynx. In two-thirds of the cases, voice changes are present at birth or in early infancy as the first manifestation.[ncbi.nlm.nih.gov]
  • […] founder mutation, Mol Syndromol 2016;7:26 ) Pathophysiology Uncertain ECM1 (extracellular matrix protein 1) is a component of the extracellular matrix and patients with LP lack functional ECM1 - this leads to hyaline deposits through an unknown mechanism Etiology[pathologyoutlines.com]
  • Etiology and Pathogenesis The molecular basis for hypermobility EDS is largely unclear.[plasticsurgerykey.com]

Pathophysiology

  • Avoiding and preventing injuries is of great importance. Assessment of the home environment with modifications to make homes “EDS safe,” such as avoiding hard, sharp edges on furniture and arrangement to prevent or minimize falls, can be helpful.[plasticsurgerykey.com]
  • Rare Brain Disorder Prevents All Fear 20. Curvilinear hyperattenuated horn-shaped lesions are well depicted by CT in the amygdaloid bodies On MR imaging, such lesions are hypointense in all pulse sequences, especially in GRE T2* weighted images 21.[slideshare.net]
  • The 2 most reliable signs of lipoid proteinosis are [3]: Hoarse voice, classically presenting as an infant with a faint or hoarse cry Thickened sublingual frenulum (a band of tissue), which prevents patients from protruding the tongue Further testing[dermnetnz.org]
  • Despite many therapeutic trials for LiP, treatment of this condition remains unsatisfactory and mainly aims at reducing morbidity and preventing complications.[jiaomr.in]
