Surgical management of recurrent squamoid eccrine ductal carcinoma of the scalp.
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.
