Adenoid cystic carcinoma occurring in the external auditory canal is very rare. Two cases are being reported. One was diagnosed on cytology based on which surgery was planned. In the second case, fine needle aspiration procedure had to be abandoned due to severe pain and a biopsy was required for its diagnosis. Morphologically, it resembles its more common salivary gland counterpart. Though severe pain during needling may be a limiting factor, adenoid cystic carcinoma of external auditory canal can be confidently diagnosed on cytology based on which surgical management can be planned.
发生在外耳道的腺样囊性癌非常罕见。本文报告两例。其中一例通过细胞学诊断，据此制定了手术方案。另一例因剧痛不得不放弃细针穿刺抽吸术，需通过活检进行诊断。形态学上，它类似于更常见的涎腺腺样囊性癌。尽管穿刺时的剧痛可能是一个限制因素，但外耳道腺样囊性癌可通过细胞学确诊，据此可制定手术治疗方案。
