The eccrine tumors are rare, locally aggressive neoplasms and have demonstrated a high metastatic potential. Although chemotherapy treatments have shown poor efficacy in metastatic stages, we report herein a case successfully treated with an original agent.
A 60-year-old woman presented with a metastatic hidradenocarcinoma in August 2004. The first lesion appeared in 1999 in the anterior fossa of the right elbow and was diagnosed as low-grade nodular hidradenoma. The tumor recurred many times in the following years after surgical and electron-beam treatments. Histopathologic findings were reviewed and confirmed a diagnosis of eccrine hidradenocarcinoma for all lesions excised (Figure 1).
