Lymph node metastasis from a primary skin carcinoid tumour.

Carcinoid tumours are uncommon neuroendocrine neoplasms that may be found anywhere in the body but are most commonly seen in the gastro-intestinal and respiratory tracts. Metastasis to the skin occurs in a small proportion of these but primary cutaneous carcinoid tumours are exceedingly rare. There have been five previous cases of primary carcinoid tumours occurring in the skin. To our knowledge, this is the first report of metastasis from a primary cutaneous carcinoid tumour.
