Nodular hidradenomas are benign sweat gland-derived tumors that can produce clinical and dermatoscopic misdiagnoses. Histologically, these tumors can be classified into eccrine and apocrine subtypes. We present the sonographic characteristics of 6 cases of apocrine nodular hidradenomas, which, to our knowledge, is so far the largest series reported. A detailed sonographic analysis included layers, body location, shape, diameters, echostructure patterns, and vascularity. Two sonographic signs not previously reported in these or other common dermatologic lesions were detected: "snow falling" and "fluid-fluid level." The sonographic characteristics of apocrine nodular hidradenomas can support their earlier and more precise diagnosis.
结节性汗腺瘤是源自汗腺的良性肿瘤，可导致临床和皮肤镜误诊。在组织学上，这些肿瘤可分为小汗腺和大汗腺亚型。我们展示了6例大汗腺结节性汗腺瘤的超声特征，据我们所知，这是迄今为止报道的最大病例系列。详细的超声分析包括层次、身体部位、形状、直径、回声结构模式和血管分布。在这些或其他常见皮肤病损中未被报道过的两个超声征象被检测到：“落雪征”和“液-液平面”。大汗腺结节性汗腺瘤的超声特征有助于其更早、更准确的诊断。
