Angiolithiasis in the parotid gland

G Anneroth, C M Eneroth, G Isacsson

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.
