Summary
Pseudoxanthoma elasticum (PXE) is a rare genetic disorder. This case report details a 30-year-old woman diagnosed with PXE, presenting with multiple dental impactions, a previously undocumented oral manifestation.
Area of Science:
- Medical Genetics
- Dermatology
- Oral Surgery
Background:
- Pseudoxanthoma elasticum (PXE) is a rare autosomal recessive genetic disorder characterized by the degeneration and calcification of elastic fibers.
- PXE primarily affects the skin, retina, and cardiovascular system, leading to characteristic clinical manifestations.
Observation:
- This report details a case of a 30-year-old woman diagnosed with PXE following a skin biopsy.
- The patient presented with pain from a semi-erupted lower first molar, and radiographic examination revealed multiple dental impactions.
- While other oral manifestations like oligodontia, amelogenesis imperfecta, and mucosal lesions have been associated with PXE, multiple dental impactions have not been previously reported.
Findings:
- Diagnosis of PXE confirmed via skin biopsy.
- Radiographic evidence of multiple dental impactions in a PXE patient.
- Identification of a novel oral manifestation associated with PXE.
Implications:
- Highlights the importance of considering PXE in patients with unexplained dental anomalies.
- Suggests a potential link between PXE and dental impactions, warranting further investigation.
- Expands the spectrum of known clinical manifestations of Pseudoxanthoma elasticum.

Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
