A dermoid cyst arising in the parotid is rare and usually represents the rare first branchial cleft type II anomaly, which can have morphology similar to a dermoid cyst. This study reports the case of a 20-year-old woman who presented with a parotid mass, which on histologic review was consistent with a dermoid cyst. This appears to be the first case report of a parotid dermoid cyst with focus on the gross and histopathologic findings and to be presented in a histopathology focused journal. The discussion includes the clinical presentation, imaging findings, gross pathology, histologic features, and differential diagnosis of parotid dermoid cysts. Although there was no prior fine needle aspiration (FNA) of the lesion in this case, parotid masses are commonly subject to FNA prior to excision. Therefore, a brief review of the FNA findings in dermoid cysts is also included.
腮腺皮样囊肿罕见，通常代表罕见的第一鳃裂II型畸形，其形态可能与皮样囊肿相似。本研究报告了一例20岁女性患者，其表现为腮腺肿块，经组织学检查符合皮样囊肿。这似乎是首例聚焦于大体和组织病理学发现并发表在以组织病理学为重点的期刊上的腮腺皮样囊肿病例报告。讨论内容包括腮腺皮样囊肿的临床表现、影像学表现、大体病理学、组织学特征及鉴别诊断。尽管该病例此前未对病变进行细针穿刺抽吸（FNA），但腮腺肿块在切除前通常会进行FNA。因此，本文还简要回顾了皮样囊肿的FNA检查结果。
