[Primary palpebral localization of a trabecular Merkel cell carcinoma (1 case)]

We report one case of Merkel cell carcinoma. They commonly arise on the eyelids of elderly patients. Others localisations are on the skin of the pelvis. Clinical aspects, histological study, associating morphological aspect, ultra-structural and immuno-histo-chemical studies are characteristics enough to differentiate this tumor others tumors of the skin like cutaneous malignant lymphoma. The origin of this tumor is still discussed, but sure neuro-endocrinal. Possibility of visceral metastases on a small number of cases (6 to 8%) must be consider when treated. Total surgical ablation should be obtained.
