Out of all benign tumors of the ceruminous glands, syringocystadenoma papilliferum is the rarest and represents only 2% of cases. It is an extremely rare benign tumor that originates from modified apocrine sweat glands. The aim of this paper was to present, according to our findings, the 18th case of syringocystadenoma papilliferum in the external auditory canal, with a detailed review of its clinical, radiological and histomorphological characteristics. A 59-year-old man reported to our clinic due to a 5×5 mm papillomatous growth at the entrance to the right external auditory canal. Histopathology indicated, after an excisional biopsy, that it was a syringocystadenoma papilliferum. The resection lines were free of tumor tissue, and the patient has no signs of tumor recurrence. Although rare, it should be considered as a differential diagnosis of lesions in this region. Complete excision is mandatory in order to avoid recurrence and potential malignant alteration.
在所有耵聍腺的良性肿瘤中，乳头状汗管囊腺瘤是最罕见的，仅占病例的 2%。它是一种起源于改良的顶泌汗腺的极罕见的良性肿瘤。本文旨在根据我们的发现，介绍第 18 例外耳道乳头状汗管囊腺瘤，并详细回顾其临床、放射影像学和组织形态学特征。一名 59 岁男性因右侧外耳道入口处有 5×5 毫米的乳头状生长而到我院就诊。经切除活检后，组织病理学提示为乳头状汗管囊腺瘤。切除线无肿瘤组织，患者无肿瘤复发迹象。虽然罕见，但应将其作为该区域病变的鉴别诊断之一。为了避免复发和潜在的恶性改变，必须进行完全切除。
