We observed an unusual and clinically unsuspected pleomorphic adenoma developing in the anterior midcervical region of a young man. The tumor developed within an ectopic parotid-type salivary gland. Surgical extirpation seems to have been curative. Embryologic concepts explaining the histogenesis of ectopic salivary glands (ESGs) are explored, and the problem of their concurrence with neoplasms is addressed. An additional feature was the presence of well-developed lymph nodes within the glandular complex, a morphologic component of ESGs that has not been previously emphasized.
我们观察到一名年轻男性的颈前中部区域出现了一种罕见且临床未被怀疑的多形性腺瘤。该肿瘤发生于异位的腮腺型唾液腺内。手术切除似乎已治愈。本文探讨了解释异位唾液腺（ESG）组织发生的胚胎学概念，并讨论了其与肿瘤并发的问题。另一个特征是在腺性复合体中存在发育良好的淋巴结，这是ESG的一个形态学组成部分，此前未被强调。
