Abstract
The aim of this study is to report a case of bilateral primary mucinous carcinoma of the eyelids. This is a case report and literature review. A 71-year-old female presented with primary mucinous carcinoma of the left upper eyelid, which was excised with Mohs surgery. One year later, she developed primary mucinous carcinoma of the right upper eyelid, which was also treated Mohs surgery. Extensive workup was negative for evidence of an unknown primary carcinoma or metastasis. Primary mucinous carcinoma of the eyelids may occur as multifocal tumors, and bilateral disease is not necessarily indicative of metastatic disease.
