Lipoid proteinosis: A systematic presentation of an unusual disease.

J Cosmet Dermatol 2022 Feb 17. Epub 2022 Feb 17.

Student Research Committee, Islamic Azad University of Medical Sciences, Sari, Iran.

Background: Lipoid proteinosis (LP) or Hyalinosis Cutis et Mucosae or Urbach-Wiethe disease is a rare autosomal recessive genodermatosis characterized by an amorphous hyaline material deposition in the skin mucosa and viscera. The clinical symptoms of this disease often begin in childhood, which persist throughout life. Skin manifestations include inflammation, scaling, acne, and eventually ulceration, and hyaline amorphous deposits in these areas of the wound cause a waxy and thick appearance on the skin.

Respir Med Case Rep 2021 18;33:101389. Epub 2021 Mar 18.

Department of Respiratory and Critical Care Medicine, Changi General Hospital, Singapore.

Lipoid pneumonia is an entity that is not commonly thought of when faced with opacities on the chest radiograph. The radiological changes of lipoid pneumonia can mimic pneumonia or malignancy. Due to this mimicry, it is commonly missed and alternative diagnoses should always be considered and ruled out when suspecting lipoid pneumonia. Read More

Sanlıurfa Training and Research Hospital, Department of Dermatology, Sanlıurfa, Turkey.

Lipoid proteinosis (LP) is a rare metabolic storage disease characterized by the storage of hyaline-like substances in the skin, mucosa, and many other organs. The aim of this study was to compare the neutrophil/lymphocyte ratio (NLR), platelets/lymphocyte ratio (PLR), and mean platelet volume (MPV) values of LP patients with healthy control group and to determine the usefulness of these parameters in determining the inflammatory status in LP patients. This study included 14 patients who were admitted to our clinic between March 2013 and January 2017 and diagnosed as LP with clinical, radiological, and histopathological examinations with 14 individuals who had no systemic inflammatory disease or malignancy and has a hemogram result.
