Colonic neuroendocrine neoplasms (NENs) are relatively rare tumors with an incidence rate of 0.11–0.21/100,000. NENs account for approximately 0.4% of colorectal neoplasms. Cutaneous metastases of colonic neuroendocrine carcinomas (NECs) are very infrequent, while cases of scalp metastasis are even fewer. |
