We report an unusual case involving a patient with sweat gland carcinoma of the cheek who presented with ipsilateral neck lymph node metastasis 10 years after his initial presentation. Pathological analysis of the surgical specimen revealed a strong reactivity of tumor cells to gross cystic disease fluid protein 15, estrogen receptor protein, and progesterone receptor protein. On the basis of these results, tamoxifen citrate therapy was initiated empirically. Our patient has been disease free for more than 3 years. Based on this and another case reported in the literature, we believe that antiestrogen therapy could prove beneficial in a subset of patients with sweat gland carcinoma. We recommend future multicenter clinical trials to assess the effectiveness of postoperative tamoxifen therapy for patients with estrogen and progesterone receptor protein–positive metastatic sweat gland carcinoma.
