Oligodontia in pseudoxanthoma elasticum

Area of Science:

• Genetics and rare diseases
• Oral and maxillofacial medicine
• Connective tissue disorders

Background:

• Pseudoxanthoma elasticum (PXE) is a rare inherited disorder affecting elastic and collagen fibers, with known manifestations in the skin, eyes, and vasculature.
• PXE follows autosomal recessive and autosomal dominant inheritance patterns.
• Systemic findings in PXE typically involve characteristic skin lesions, retinal abnormalities (angioid streaks), and vascular calcification.

Observation:

• This report details a unique case of a patient diagnosed with Pseudoxanthoma elasticum.
• The patient presented with a rare dental anomaly: agenesis of most permanent teeth (oligodontia).
• This specific association between PXE and oligodontia has not been previously documented in English medical literature.

Findings:

• The study highlights a previously unreported clinical manifestation of Pseudoxanthoma elasticum.
• The patient exhibited significant oligodontia, a condition characterized by the congenital absence of multiple permanent teeth.
• This finding expands the known spectrum of dental anomalies associated with PXE.

Implications:

• The identification of oligodontia in PXE suggests a potential link between the genetic basis of PXE and dental development.
• This case underscores the importance of comprehensive dental evaluations in patients diagnosed with PXE.
• Further research is warranted to explore the genetic and molecular mechanisms underlying dental agenesis in PXE patients, potentially informing future diagnostic and therapeutic strategies.
