The differential diagnosis of a buccal soft tissue mass containing calcified bodies includes a phlebolith associated with a vascular lesion, such as a hemangioma with a calcified intravascular thrombus, and diseases such as sialolithiasis, traumatic myositis ossificans, calcified acne lesion, neoplasm, and calcified lymph nodes, including tuberculosis. The appearance of the calcified bodies on plain radiographs may help to differentiate these entities. Computed tomography, magnetic resonance imaging, and ultrasonography are also useful for differentiating the soft tissue lesions. We report a 17-year-old girl with a small mass containing a calcified body in the anterior portion of the masseter muscle. The mass was resected surgically and evaluated histologically, confirming the diagnosis of phlebolith. We also discuss the differential diagnosis of a buccal soft tissue mass containing calcifications and suggest that the immunolocalization of CD31 at capillaries in the mass may help to diagnose as a phlebolith.
含有钙化小体的颊部软组织肿块的鉴别诊断包括与血管病变相关的静脉石，如伴有钙化血管内血栓的血管瘤，以及涎石病、创伤性骨化性肌炎、钙化性痤疮病变、肿瘤和钙化淋巴结（包括结核）等疾病。普通X线片上钙化小体的表现可能有助于鉴别这些实体。计算机断层扫描、磁共振成像和超声检查对鉴别软组织病变也很有用。我们报告一名17岁女孩，在咬肌前部有一个含有钙化小体的小肿块。该肿块经手术切除并进行组织学评估，确诊为静脉石。我们还讨论了含有钙化的颊部软组织肿块的鉴别诊断，并提出肿块内毛细血管处CD31的免疫定位可能有助于诊断为静脉石。
