Purpose: To report a case of Merkel cell carcinoma localized to the right lower eyelid treated by surgical resection alone.
Case summary: A 81-year-old woman visited the clinic with a painless and red-violet with 0.8 × 0.5 cm size tumor at the right lower eyelid, which developed 1 year ago. The patient complain that tumor begun to grow from 2 months ago. Surgical resection and biopsy were performed for treatment and diagnosis. We evaluated histologic exam using immunohistochemistry and it was positive for CD56 and chromogranin. Finally the patient was diagnosed as Merkel cell carcinoma of eyelid. The resection margin was not invaded and no additional resesction was performed. Local recurrence and metastasis were not observed for eight months.
Conclusions: Merkel cell carcinoma is highly aggressive neuroendocrine malignancy and occurrence is rare. If Merkel cell carcinoma is localized to the skin, surgical resection is the primary treatment option and adjuvant radiation therapy can be used. We report a case of Merkel cell carcinoma localized to lower eyelid that was surgically resected and showed good outcome without recurrence and metastasis.
