Lipoid proteinosis is a rare autosomal recessive condition affecting the majority of organ systems, but predominantly involving skin and mucous membranes. The mucocutaneous infiltration due to accumulation of a hyaline material is positive for both sudanophil and periodic acid-Schiff reagents. This was illustrated in a 14-year-old girl with parental consanguinity, who had classic manifestations.

Sudanophil material was seen at the boundary parts between dentine and widened predentine, and between widened preosseous matrix and calcified bone, but it was not seen at the area corresponding to the zone of provisional calcification. These facts suggest that the localization of sudanophil material in hard tissue of rat with Be rickets was similar to that in vitamin D deficient-induced rickets.

In the skin, the most relevant changes are those exhibited by epidermal "flask" cells. These cells are generally rather lean, tall and PAS-positive in "dry" animals and in those 24 hr after replacement in water, whereas in animals placed back in water for a week "flask" cells are often large and faintly stainable.

The oral regions most frequently affected are the lips, the back of the tongue, the frenulum of the tongue, the palate and the back wall of the pharynx. The general impression is that older patients usually have more marked manifestations than younger, indicating that the oral lesions may become more severe with increasing age.
