We describe a 37-year-old woman who presented with progressive mouth dryness. Physical examination revealed long-standing plaques on the face and upper limbs, papular lesions of the oral cavity and tongue firmness. A lower lip biopsy was performed. Light microscopy demonstrated accumulation of PAS-positive material around blood vessels, capillaries and salivary gland canaliculi as well as focally massive hyaline deposits in the submucosa. Immunohistochemistry revealed widespread presence of type IV collagen in the hyaline material and around thickened blood vessels. Laminin immunoreactivity was particularly strong at thickened basement membranes. The above findings were compatible with lipoid proteinosis, which is likely to involve primary perturbation of collagen metabolism and production of glycoproteins.

Background: Lipoid pneumonia (LP) is a rare disease caused by the accumulation of lipids and lipid-laden macrophages in the alveoli inducing damage. LP is difficult to differentiate from other similar diseases without pathological evidence, such as upper respiratory tract infection (URTI), pneumonia, cryptogenic organizing pneumonia (COP), pulmonary alveolar proteinosis (PAP), lung mucinous adenocarcinoma and pulmonary edema. Given the high misdiagnosis rate and limited statistical clinical and treatment data, there is an urgent need for novel indicators of LP.

Lipoid proteinosis is a rare genetic disorder affecting the skin, mucous membranes, and central nervous system. Here, we present the case of a 35-year-old female who presented with two episodes of seizures followed by loss of consciousness and injury to the nose. A CT scan and MRI of the brain revealed small symmetrical calcifications in the bilateral medial temporal lobes, a finding highly suggestive of lipoid proteinosis.

Article Synopsis
- Lipoid proteinosis (LP), also known as Urbach-Wiethe disease, is a rare genetic disorder that causes abnormal material buildup in various tissues, including skin and organs, and can sometimes lead to neurological issues.
- A case of a 25-year-old male presented with unexpected left leg weakness, which diverged from the typical symptoms of LP like skin and voice changes, highlighting the need to explore LP's possible neurological effects.
- Imaging revealed brain abnormalities and possible complications involving the liver and thyroid, indicating that LP might be linked to motor weakness and suggesting a need for more research into its neurological manifestations.
