Abstract
Neuroendocrine tumors derive from the diffuse neuroendocrine system producing hormonal peptides and/or biogenic amines. Histologically neuroendocrine differentiation includes ultrastructural demonstration of neurosecretory granules and staining with immunhistochemical markers such as neuron-specific enolase, chromogranin, synaptophysin, and cytokeratin. Neuroendocrine carcinoma of the skin is rare but can be shown as an initial manifestation of metastatic neuroendocrine carcinoma as well as primary cutaneous neuroendocrine carcinoma. Histological differentiation between primary cutaneous Merkel cell carcinoma and metastatic neuroendocrine carcinoma of the skin is difficult and clinicai correlation is important. We report a case of metastatic neuroendocrine carcinoma of the lung occurring on the scalp as a single nodule in a 65-year-old female who previously diagnosed with adenocarcinoma of the stomach.
