RESUMEN
Pseudoxanthoma elasticum is a rare genetic disorder causing degeneration and calcification of elastic fibers, leading to injuries in the skin, retina, and cardiovascular system. This report describes a case of a 30-year-old woman whose diagnosis of pseudoxanthoma elasticum was confirmed after a skin biopsy. The patient presented at the Clinical Management Unit of the Department of Oral and Maxillofacial Surgery, Virgen del Rocio Hospital (Seville, Spain) with pain related to a semi-erupted lower first molar. Radiologic examination disclosed multiple dental impactions. Cases of oligodontia, amelogenesis imperfecta, and mucosal lesions related to pseudoxanthoma elasticum were found in the current literature, but there were no reports of multiple dental impactions.
