A dermoid cyst is a choristoma that arises from the displacement of ectoderm to a subcutaneous location along embryonic closure lines. Rarely dermoids have a deep intraorbital component that is connected to a superficial component through a defect in bone, also known as dumbbell dermoid. We report the case of a young boy who was misdiagnosed having chronic osteomyelitis of the zygoma, based on the clinical and radiological features. On surgical exploration he was found to have a dumbbell-shaped dermoid with a bony defect. Histopathological features were consistent with a diagnosis of dermoid cyst with chronic inflammation.
皮样囊肿是一种迷离瘤，由外胚层沿胚胎闭合线移位至皮下位置而形成。皮样囊肿很少有深部眶内成分，该成分通过骨缺损与浅表成分相连，也称为哑铃状皮样囊肿。我们报告一例年轻男孩的病例，根据临床和影像学特征，其最初被误诊为颧骨慢性骨髓炎。手术探查发现他患有一个带有骨缺损的哑铃状皮样囊肿。组织病理学特征符合伴有慢性炎症的皮样囊肿诊断。
