Lymph Node Merkel Cell Carcinoma without Primary: Long Term Survival
Introduction: Merkel cell carcinoma (MCC) is a rare aggressive cutaneous neuroendocrine carcinoma with a high rate of metastasis. Approximately 5% of MCC are found in the lymph nodes (LNs) without a primary tumor on the skin.
Aim(s): To report clinical, histological and therapeutic aspects of a patient with inguinal LNs metastasis without evidence of primary tumor, free of recurrence actually, ten years after treatment.
Materials and methods: In June 2009, a 62-year-old-male presented with a 4 cm left inguinal LN. This had been present for several months but had recently increased in size. There were no primary skin lesions. Initially he underwent fine needle aspiration cytology and then un excisional biopsy.
