Clear cell hidradenoma (CCH) is a tumour originating from the eccrine sweat glands. It usually presents in the limbs, axilla or trunk. CCH of the breast is rare and can present as a cystic lesion in the breast that can be easily misdiagnosed as malignancy. We report a 36-year-old female patient who presented at the Sultan Qaboos University Hospital Breast Clinic, Muscat, Oman, in 2018 with a lump in her left breast. Ultrasound examination reported a complex cystic lesion with a solid, vascular component. An ultrasound-guided core needle biopsy was suggestive of clear cell hidradenoma. Surgical excision was performed and histopathology confirmed the diagnosis of CCH of the breast. This is the first ever case of a diagnosis of CCH made using core needle biopsy. CCH can be challenging to diagnose; therefore, awareness of its histopathological and ultrasonographic features are essential to avoid misdiagnosis and over treatment.
透明细胞汗腺瘤（CCH）是一种起源于外分泌汗腺的肿瘤。它通常发生在四肢、腋窝或躯干。乳房的 CCH 较为罕见，可表现为乳房内的囊性病变，容易误诊为恶性肿瘤。我们报告了 1 例 36 岁女性患者，2018 年在阿曼马斯喀特的苏丹卡布斯大学医院乳房诊所就诊，左乳房有肿块。超声检查报告为复杂囊性病变，有实性、血管成分。超声引导下的核心针活检提示透明细胞汗腺瘤。进行了手术切除，组织病理学证实为乳房 CCH。这是首例使用核心针活检做出的 CCH 诊断。CCH 的诊断具有挑战性；因此，了解其组织病理学和超声特征对于避免误诊和过度治疗至关重要。
