Palate sialolipomas are rare. Less than 10 cases located in the hard palate are reported to our knowledge. We report a case of hard palate sialolipoma, peculiar by the intratumor vascular patterns. A 67-year-old man presented with a 1.5 cm lesion of the oral hard palate. The lesion was surgically resected. On microscopy, the lesion, partly encapsulated, consisted of a proliferation of mature adipocytes containing normal minor salivary gland tissue and branching intratumoral vessels of varied size with irregularly thickened wall and papillary projections or tufts. The microscopic features of the tumor we report suggest that vascular malformation-like patterns may occur in sialolipomas of the hard palate. This morphological vascular peculiarity should be acknowledged since it may represent source of hemorrhage.
腭部涎脂瘤很罕见。据我们所知，位于硬腭的病例报告不足10例。我们报告一例硬腭涎脂瘤，其肿瘤内血管模式较为特殊。一名67岁男性患者，口腔硬腭出现一个1.5厘米的病变。该病变经手术切除。显微镜下，病变部分被膜包裹，由成熟脂肪细胞增生组成，其中含有正常的小涎腺组织以及大小不一的分支状肿瘤内血管，血管壁不规则增厚，有乳头状突起或簇状结构。我们报告的肿瘤微观特征表明，硬腭涎脂瘤可能出现血管畸形样模式。这种形态学上的血管特殊性应予以重视，因为它可能是出血的来源。
