Lipoid proteinosis is a sporadic congenital metabolic disorder which is characterized by deposition of hyaline material in dermis, submucosal connective tissue, and various internal organs. It has an extremely low prevalence rate with less than 300 cases reported so far. This progressive disease has a vast spectrum of manifestations ranging from asymptomatic lesions to fatal seizures and respiratory obstruction making timely diagnosis of this rare disorder an imperative task for oral health care practitioners. We report a case of characteristic oral manifestations of lipoid proteinosis in a 28-year-old male patient along with a review of relevant prevailing literature.

Mucins undergo change in its pattern and intensity in varying grades of OED/OSCC. Although in GIT and other mucosa, the expression of altered mucin is a recognized factor, seldom research has been done in OED and OSCC. Thus, the present study could be the stepping stone in the exploration of mucinous alteration in OED and OSCC.
