The origin of hidradenoma was from the eccrine sweat glands, generally found in the head, face, and upper extremity regions. This lesion has not been reported to be large enough to present in the ear lobule. Hence, its description in the otolaryngology literature is extremely rare. The rarity of this neoplasm and failure to identify its morphologic features may lead to misdiagnosis. We present a benign clear cell hidradenoma of the right ear lobule in a 45-year adult male. We encountered a tumour measuring 4 cm in diameter. Mass shows ulcerated surface, bleeds on touch and remained a diagnostic dilemma till an excision biopsy was carried out and a histopathological report confirmed that it was a hidradenoma of clear cell variant. The aim of presenting this case report was interesting in the fact that it has added clear cell hidradenoma in the final diagnosis, in an uncommon site of presentation.
汗腺腺瘤起源于小汗腺，通常见于头、面及上肢区域。尚未有报道称该病变大到足以出现在耳垂。因此，其在耳鼻喉科文献中的描述极为罕见。这种肿瘤的罕见性以及未能识别其形态学特征可能导致误诊。我们报告一例45岁成年男性右耳垂的良性透明细胞汗腺腺瘤。我们遇到一个直径4厘米的肿瘤。肿物表面溃疡，触之出血，在进行切除活检并获得组织病理学报告证实为透明细胞型汗腺腺瘤之前，一直是诊断难题。本病例报告的目的有趣之处在于，它在一个不常见的发病部位的最终诊断中增加了透明细胞汗腺腺瘤。
