Collagenous fibroma (desmoplastic fibroblastoma) is a distinctive yet uncommon fibrous soft tissue tumor. These tumors are rather nondescript in their morphological appearance and have been diagnosed as fibromas or some other benign mesenchymal lesions for years. The most common sites are the upper extremities, followed by the lower extremities. Rare lesions arise in the head and neck region. We report a rare case in the oral cavity and present its unique histopathological features (central fat entrapment) besides others, and diffusely strong vimentin immunopositivity.
胶原纤维瘤（促纤维增生性成纤维细胞瘤）是一种独特但不常见的纤维性软组织肿瘤。这些肿瘤在形态外观上相当不典型，多年来一直被诊断为纤维瘤或其他一些良性间叶性病变。最常见的部位是上肢，其次是下肢。罕见病变发生在头颈部区域。我们报告一例口腔罕见病例，并展示其独特的组织病理学特征（中央脂肪包埋）以及其他特征，还有波形蛋白弥漫性强免疫阳性。
