123I-MIBG SPECT of Merkel cell carcinoma.

Abstract

131I-MIBG may be useful in the detection of neuroendocrine tumours. Merkel cell carcinoma is a neuroendocrine tumour of the skin. We evaluated a patient with Merkel cell carcinoma using 123I-MIBG single photon emission computed tomography (SPECT) which demonstrated tumour accumulation of the radiotracer in the right eyelid. This result suggests that 123I-MIBG SPECT may be useful in the evaluation of Merkel cell carcinoma.
