Report on a rarity, consisting in the anatomic connexion of a parotid cyst with serous fluid and a congenital dysontogenesis near the ear. The latter will reduced to remains of the ectoderm of the first branchial cleft, remaining during the migration of the ear-"anlage" to the upper dorsal direction and interpreted as equivalent of a neck-ear-fistula. During embryogenesis apparently happens a collision between the remains of ectoderm and the ducts of the parotid-"anlage", developing from the buccal cavity. Clinical aspects, diagnosis, differential diagnosis and treatment were discussed. The management comprises exstirpation of the cyst after parotidectomy with preservation of the facial nerve.
关于一种罕见病例的报告，该病例包括一个含有浆液的腮腺囊肿与耳部附近先天性发育异常的解剖学联系。后者被归结为第一鳃裂外胚层的残余部分，在耳部“原基”向上背侧迁移过程中留存下来，并被解释为相当于颈耳瘘。在胚胎发育过程中，外胚层残余部分与从颊腔发育而来的腮腺“原基”导管之间显然发生了碰撞。文中讨论了临床症状、诊断、鉴别诊断及治疗方法。治疗措施包括在保留面神经的情况下进行腮腺切除术后摘除囊肿。
