The purpose of this study is to clarify the origin and nature of so-called hairy polyps or dermoids of the pharynx, which are often thought to be a variant of pharyngeal teratoma. For this purpose, a case is reported of a dermoid polyp involving the middle ear of an infant, the features of multiple examples of pharyngeal dermoid polyps and teratomas received for consultation by the Armed Forces Institute of Pathology are examined, and selected pertinent reports from the literature are reviewed. All three means are used to support the conclusion that these lesions are choristomatous developmental anomalies arising from the first branchial cleft area and that they essentially represent heterotopic accessory "ears" (auricles) without the growth potential of a teratoma.
本研究的目的是阐明所谓的咽部毛发样息肉或皮样囊肿的起源和性质，它们常被认为是咽畸胎瘤的一种变体。为此，报告了1例累及婴儿中耳的皮样息肉病例，检查了武装部队病理研究所会诊的多例咽皮样息肉和畸胎瘤的特征，并复习了文献中精选的相关报告。所有这三种方法都用于支持以下结论：这些病变是起源于第一鳃裂区域的迷芽瘤性发育异常，它们本质上代表异位副“耳”（耳廓），不具有畸胎瘤的生长潜能。
