Abstract

The development of polypoidal structures, derived from organization of amniotic squamous debris, in the middle-ear cavity of 3 infants is described. The lesions mimicked the development of amnion nodosum lesions of the placenta and were attached to either the tympanic membrane or the head of the stapes. They were accompained by atypical metaplastic changes in the middle-ear epithelium. While the clinical significance of the structural changes is uncertain, they strengthen the case for histopathological examination of the middle ear in infant necropsies.

摘要

本文描述了3例婴儿中耳腔内由羊膜鳞状碎屑组织形成的息肉样结构的发育情况。这些病变类似于胎盘羊膜结节病变的发展,附着于鼓膜或镫骨头。它们伴有中耳上皮的非典型化生改变。虽然结构变化的临床意义尚不确定,但它们进一步证明了在婴儿尸检时对中耳进行组织病理学检查的必要性。
