[Merkel cell carcinoma of the eyelid: a case report].

PURPOSE/METHODS: We report the case of a 73-year-old white female suffering from Merkel cell carcinoma (MCC) of the eyelid with an evolution of two and half months. MCC is a cutaneous neuroendocrine malignant tumor arising from Merkel cells. These cells are common along the eyelid margin in between the eyelashes. It is infrequent but highly aggressive and with potential metastases. Immunohistochemical and ultrastructural studies may be necessary for an histopathological diagnosis.

RESULTS/CONCLUSIONS: Tumor resection with wide security margins must be undertaken as soon as possible. In addition, the patient may require postoperative radiotherapy.
