Sweat glands belong to skin appendages. Sweat gland tumors are uncommon, especially when they occur as malignant tumors in the breast. We report a case of malignant sweat gland tumor of the breast, including imaging and pathological findings.
A 47-year-old woman visited our hospital with a non-tender palpable lesion in her left breast. The lesion had not shown changes for 10 years. However, it recently increased in size. Sonography showed a well circumscribed cystic lesion with internal debris and fluid-fluid level. Magnetic resonance imaging showed a well circumscribed oval mass with T1 hyper-intensity compared to muscle and T2 high signal intensity. There was a small enhancing mural component in the inner wall of the mass. The tumor was resected. Its pathologic result was a malignant transformation of benign sweat gland tumor such as hidradenoma. The lesion was treated with excision and radiation therapy. At 1-year follow up, there was no local recurrence or metastasis in the patient.
In the case of a rapid growing cystic mass in the nipple and subareola, it is necessary to distinguish it from a malignant sweat gland tumor.
汗腺属于皮肤附属器。汗腺肿瘤并不常见，尤其是发生在乳腺的恶性肿瘤。我们报告一例乳腺恶性汗腺肿瘤病例，包括影像学和病理检查结果。
一名47岁女性因左侧乳腺可触及无痛性肿物前来我院就诊。该肿物10年来无变化，但近期增大。超声检查显示一个边界清晰的囊性肿物，内部有碎屑及液-液平面。磁共振成像显示一个边界清晰的椭圆形肿物，相对于肌肉呈T1高信号，T2高信号强度。肿物内壁有一小的强化壁层成分。肿瘤被切除。病理结果为良性汗腺肿瘤如汗腺瘤发生恶变。该病变采用手术切除及放射治疗。随访1年，患者无局部复发或转移。
对于乳头及乳晕下快速生长的囊性肿物，有必要将其与恶性汗腺肿瘤相鉴别。
