[Mucinous sweat gland carcinoma of a toe with metastasis to the maxilla. A case report].

Malignant tumors of the maxilla are rare. In addition to primary tumors metastatic disease has to be considered. Renal cell carcinomas, carcinomas of the breast, lung and adenocarcinomas are constituting the most frequent primary lesions for maxillary metastases. To the best of our knowledge, we present the first case of a mucinous sweat gland carcinoma metastasizing to the maxilla four years after primary diagnosis. Thirty-two months after resecting the hemimaxilla, there are no signs of local recurrence. Although skin tumors only rarely develop distant metastases, sweat gland carcinomas should be included in the differential diagnosis of tumors metastasizing to the maxilla.
