Neuroendocrine carcinoma of the skin usually occurs in elderly individuals. Head and neck are the most common primary sites followed by the extremities and trunk.

Diagnosis was based on the results of the examination of a metastasis in the inguinal lymph nodes. The lesion at the Labium minus pudendi which is to be considered the primary tumor was detected several months later. Diagnosis of Merkel cell tumor until recently had depended on ultrastructural demonstration of dense-core membrane-bound granules.
