Abstract

Pindborg tumour or calcifying epithelial odontogenic tumor (CEOT) is a rare and benign odontogenic neoplasm that was first described by a Dutch pathologist Jens Jorgen Pindborg in 1955. The most common clinical manifestation of CEOT is that of a localized, slow growing hard tissue swelling of the posterior jaws. Radiographically, it presents as a mixed radiolucentradiopaque lesion. Though the histopathological presentation is quite distinct, cases have been reported to show slight variations from the usual picture. One such rare variant is the presence of abundant clear cells intermixed with the tumor cells. The significance of this variant is that it has been shown to have a more aggressive behaviour with greater tendency to recur if inadequately removed. We report a case of clear cell variant of CEOT with an uncommon site of presentation in the anterior mandible.

前下颌骨平堡肿瘤的透明细胞变异:病例研究和其他组织学变异的概述。
Pindborg肿瘤或钙化上皮性牙源性肿瘤(CEOT)是一种罕见的良性牙源性肿瘤,由荷兰病理学家Jens Jorgen Pindborg于1955年首次描述。CEOT最常见的临床表现是后颌骨的局部,缓慢生长的硬组织肿胀。x线摄影表现为混合性放射线室不透明病变。虽然组织病理表现是相当不同的,病例报告显示轻微的变化,从通常的图片。其中一种罕见的变异是大量透明细胞与肿瘤细胞混杂在一起。这种变异的意义在于,如果移除不充分,它会有更大的复发倾向,具有更强的攻击性行为。我们报告一例透明细胞变异的CEOT与一个不寻常的位置呈现在前下颌骨。
