Abstract
A 75-year-old man developed a left middle finger tumor. The tumor was diagnosed as malignant eccrine spiradenoma, and he underwent amputation of the left middle finger ; a lymph node resection of the left axilla was also done. One year later, a chest CT scan revealed a small nodule in the apex of the left lung. To confirm the diagnosis, a partial resection of the left lung was performed during video-assisted thoracoscopic surgery. On histopathology, the pulmonary tumor was diagnosed as a metastasis of the malignant eccrine spiradenoma. Subsequently, 5 years after the left lung resection a partial resection of the right lung was required due to the presence of a metastasis. Currently, the patient is alive without evidence of recurrence. We report this rare case, together with a review of the relevant literature.
