A Case of Neuroendocrine Carcinoma / 대한피부과학회지

Neuroendocrine neoplasms have been described in virtually every organ where neuroendocrine cells are distributed throughout the body. It commonly exhibits multiple lines of divergent differentiation. We report a case of neuroendocrine carcinoma occurring in a 52-year-old woman. She had multiple subcutaneous nodules on the trunk. The light microscopic appearance and immunohistochemical stains were consistent with a neuroendocrine carcinoma. But it showed some differences from Merkel cell carcinoma in clinical and immunohistochemical findings. It may be strongly suggested that it was probably metastatic neuroendocrine carcinoma.
