Merkel cell carcinoma (MCC) is a rare but very aggressive neuroendocrine tumor of the skin in elderly patients with higher mortality compared with melanoma. No evidence-based standardized chemotherapy exists for metastasized patients.

We report the case of an 87-year-old patient with the history of resection of a large MCC of the parietal scalp planned for radiotherapy and staged with FDG PET/CT showing disseminated distant metastases. 68Ga-DOTATATE PET/CT revealed more extensive tumor load compared with FDG, and due to the intensive expression of somatostatin receptors the patient qualified for 90Y DOTATOC therapy.
