Squamoid eccrine ductal carcinoma (SEDC) is an exceedingly rare tumor that shows both squamous differentiation and adnexal ductal differentiation. As our review of the literature revealed, only a total of 7 cases were reported to date. We report an additional case of SEDC occurring on the scalp of a 53-year-old man. Despite complete excision by conventional technique with clear margin, the lesion recurred within a 3-month period, with regional lymph node metastasis. The tumor was completely removed, and the large scalp defect was reconstructed by using scalp rotation flap. We present a case of recurrent SEDC on the scalp, and we surgically resected this tumor. In addition, the large scalp defect was reconstructed successfully with scalp flap, and no recurrence has been observed in the patient's postoperative follow-ups.
鳞状小汗腺导管癌（SEDC）是一种极其罕见的肿瘤，兼具鳞状分化和附属器导管分化。正如我们对文献的回顾所示，迄今为止总共仅报道了7例。我们报告了另外1例发生在一名53岁男性头皮上的SEDC病例。尽管采用传统技术完整切除且切缘清晰，但病变在3个月内复发，并伴有区域淋巴结转移。肿瘤被彻底切除，使用头皮旋转皮瓣修复了大面积的头皮缺损。我们展示了1例头皮复发性SEDC病例，并对该肿瘤进行了手术切除。此外，成功地用头皮皮瓣修复了大面积的头皮缺损，患者术后随访未观察到复发情况。
