Sweat gland carcinomas are rare. Given this, they can pose a diagnostic challenge especially in shave biopsy specimens. We present a case of ductal eccrine carcinoma with extensive squamoid differentiation that was repeatedly misdiagnosed by multiple dermatopathologists as squamous cell carcinoma in the initial few biopsies. As the distinction between these two neoplasms is crucial to patient management, we highlight the histologic features of this uncommon entity to highlight the potential diagnostic pitfalls.
汗腺癌很罕见。鉴于此，它们可能带来诊断挑战，尤其是在剃除活检标本中。我们报告一例具有广泛鳞状分化的导管小汗腺癌，在最初几次活检中，多位皮肤病理学家多次将其误诊为鳞状细胞癌。由于这两种肿瘤的区分对患者管理至关重要，我们强调了这种罕见实体的组织学特征，以突出潜在的诊断陷阱。
