Merkel's cell carcinoma is a rare, primary cutaneous, neuroendocrine tumour that is locally aggressive and has potential for metastatic spread. A 39-year-old female patient with biopsy-proven Merkel's cell carcinoma of the lower extremity is described with regard to tumour size, location, attenuation of the primary lesion, and lymph mode metastasis. Clinical imaging modality findings form the basis of this report; computed tomography and magnetic resonance imaging findings that have an important role in the initial work-up and the follow-up of patients with Merkel's cell carcinoma are highlighted.
