Angiolithiasis in the parotid gland
International Journal of Oral Surgery
|April 1, 1978
Summary
Salivary gland angiolithiasis, a rare condition, was studied in a young patient. These angioliths developed from a regressed hemangioma and were composed of pure apatite, offering new insights into their formation.
Area of Science:
- Pathology
- Mineralogy
- Histology
Background:
- Angiolithiasis in salivary glands is exceptionally rare, limiting understanding of its morphology and histogenesis.
- Existing knowledge on salivary gland angiolithiasis is scarce due to its infrequent occurrence.
Observation:
- Six angioliths from a 19-year-old female's left parotid gland were analyzed using histological, microradiographic, and diffractometric methods.
- The angioliths originated from a regressed hemangioma present since early childhood.
- Encapsulated angioliths displayed laminated structures with varying mineral content and homogeneous areas, featuring highly mineralized centers.
Findings:
- All examined angioliths consisted of pure apatite.
- The matrix of the nodules contained erythrocytes and fibroblasts, confirming the diagnosis of angiolithiasis.
Implications:
- This study provides detailed morphological and mineralogical insights into salivary gland angiolithiasis.
- Understanding the histogenesis from hemangioma contributes to the limited knowledge of this rare condition.
- The findings highlight the apatite composition and cellular components within these salivary gland stones.
