Scalp metastasis as initial presentation of neuroendocrine carcinoma
Abstract
Neuroendocrine carcinomas are a rare, heterogenous group of malignancies that arise from neuroendocrine cells throughout the body. Cutaneous metastasis of neuroendocrine carcinoma is uncommon and they can be easily misdiagnosed as benign epidermal cysts or Merkel cell carcinoma. Collectively, histopathology, immunochemical profile, biochemical markers, and nuclear imaging can guide the diagnosis of neuroendocrine metastasis and localization of primary tumors.
