[Mandibular metastasis as the first manifestation of adenocarcinoma of the prostate].

We present a case of mandibular metastasis as the first manifestation of a disseminated prostate carcinoma. After commenting on the exceptional nature of the case, we underline the importance of histochemical markers (Acid phosphatase. PSA) to determine the non-filiated origin of a metastasis. It is advisable for this to be carried out systematically in all cases of metastasis of indeterminate origin.
