[How I explore... a cutaneous metastasis. What are you, from where are you coming from?].

Cutaneous metastases may accompany up to 3 to 10% of all malignancies. They are usually identified after diagnosing the primary neoplasm. However, their disclosure can be synchronous, or the metastasis may be the initial finding qualified as "precocious". The identification of the primary neoplasm sometimes proves to be difficult. Gender of the patient, the aspect and distribution of the metastases, as well as the histological and immunohistological examinations help establishing the diagnosis. The prognosis of the metastatic disease is often poor.
