Mucosal calcified nodule of the hard palate in an infant: case report and review of the literature.

Pathological calcifications of skin manifest as small or large deposits of calcium in the dermis and subcutaneous tissues. One form of these conditions is described as subepidermal calcified nodule seen on the facial skin of young children without any underlying connective tissue disease or any abnormality in calcium or phosphorus metabolism. The oral cavity is rarely affected. Recently, two cases were reported in the oral mucosa and the term "mucosal calcified nodule" was coined for such an entity. We report another case of such a process involving the oral mucosa of a 5-month-old infant who presented with an enlarging lesion at the junction of the hard and soft palate.
