Primary mucinous eccrine carcinoma (PMEC) is a rare skin adnexal neoplasm. Most common sites for this tumor are eyelid and periocular tissues. Periumbilical region is a rare site for this neoplasm. The main differential diagnosis for this neoplasm is metastatic mucinous adenocarcinoma. It is important to correctly diagnose this tumor because the prognosis of this neoplasm is better than metastatic disease. To differentiate it from metastasis complete clinical, radiological, histopathological, and immunohistochemical work up is required.[1]
