Abstract
Merkel cell carcinoma is a rare malignant neoplasm of the skin which is locally invasive
and frequently metastasizes to lymph nodes, liver, lungs, bone, and brain. Computed
tomographic and pathologic findings in an elderly woman with Merkel cell carcinoma
of the buttock and regional nodal metastasis are reported. The presence of calcitonin
and neuron-specific enolase within the tumor supports the theory that Merkel cell
carcinoma is a neuroendocrine tumor derived from the APUD (amine precursor uptake
and decarboxylase) system.
