Gastric Metastasis of Merkel Cell Carcinoma
Merkel cell carcinoma (MCC) is an uncommon and highly malignant skin tumor of neuroendocrine origin that exhibits rapid growth, early distant metastasis, and poor prognosis. About 80% are attributed to Merkel cell polyomavirus and the remainder to UV exposure. The most common metastatic sites are are lymph nodes, liver, lungs, and central nervous system; gastric metastasis is rare. This procedure video illustrates laparoscopic resection of a Merkel cell carcinoma that metastasized to the stomach of a woman in her 70s with an asymptomatic mass of the gastric fundus that was shown to be metabolically active by PET scan.
