The objective of this study was to present an unusual case of isolated dystrophic calcification in masseter and the diagnostic challenge it posed. A case report on a 14-year-old boy presented with swelling in left parotid region along with the review of literature was reported. Histopathological and biochemical analyses of the excised mass diagnosed this affliction as dystrophic calcification. Dystrophic calcification is deposition of calcium salt in degenerated tissues in the presence of normal calcium and phosphorous metabolism. It usually occurs in injured tissues. This is different from systemic mineral imbalance causing metastatic calcification and needs to be differentiated. On reviewing the literature, this appears to be the second reported case in the world wide literature. The unique presentation, diagnosis, and surgical management of dystrophic calcification have been described.
本研究的目的是呈现一例咬肌孤立性营养不良性钙化的罕见病例及其所带来的诊断挑战。报告了一例14岁男孩左侧腮腺区肿胀的病例报告并对相关文献进行了综述。对切除肿物的组织病理学和生化分析将此病症诊断为营养不良性钙化。营养不良性钙化是在钙和磷代谢正常的情况下钙盐在变性组织中的沉积。它通常发生在受损组织中。这与导致转移性钙化的全身性矿物质失衡不同，需要加以区分。经文献检索，这似乎是全球文献中报道的第二例。文中描述了营养不良性钙化独特的表现、诊断及手术处理。
