Hidradenocarcinoma (HAC) is a rare adnexal tumor associated with the potential for locoregional recurrence and systemic metastasis. The clinical appearance of HAC is nonspecific, frequently presenting as a solitary firm subcutaneous nodule or plaque on the head and neck region or distal extremities. These tumors show histomorphologic heterogeneity, as they can be low and high grade. Distinguishing HAC from hidradenoma, especially the low-grade variant of HAC, can be challenging as both tumors can show histologic overlapping features. In this article, we describe a case of a 33-year-old patient presenting with a low-grade HAC of the plantar foot who was subsequently found to have lymph node metastasis.
汗腺癌（HAC）是一种罕见的附属器肿瘤，有局部复发和全身转移的可能。汗腺癌的临床表现不具有特异性，常表现为头颈部或远端肢体的单个坚实皮下结节或斑块。这些肿瘤表现出组织形态学异质性，可分为低级别和高级别。将汗腺癌与汗腺瘤区分开来，尤其是低级别汗腺癌变体，可能具有挑战性，因为这两种肿瘤可表现出组织学重叠特征。在本文中，我们描述了一例33岁足底低级别汗腺癌患者，该患者随后被发现有淋巴结转移。
