    Area of Science:

    • Oncology
    • Dermatology
    • Pathology

    Background:

    • Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer with high metastatic potential.
    • MCC frequently metastasizes to lymph nodes, liver, lungs, bone, and brain.

    Observation:

    • This report details the computed tomographic and pathologic findings of MCC in an elderly woman.
    • The tumor was located on the buttock with evidence of regional nodal metastasis.

    Findings:

    • Calcitonin and neuron-specific enolase were detected within the Merkel cell carcinoma.
    • These findings support the theory of MCC originating from the amine precursor uptake and decarboxylase (APUD) system, classifying it as a neuroendocrine tumor.

    Implications:

  • Understanding the neuroendocrine nature of MCC is crucial for diagnosis and treatment.
  • Further research into APUD system tumors can improve therapeutic strategies for rare skin cancers like MCC.
