Abstract
Brain and Head and neck metastases are rare in prostatic carcinoma patients. In this report we present a very uncommon case of the concomitant occurrence of a prostatic adenocarcinoma with neck metastases and an advanced laryngeal squamous cell carcinoma without neck metastases. The presence of cervical lymph node prostate adenocarcinoma metastasis concomitantly with a laryngeal squamous cell carcinoma is at least intriguing and may remind us of a rare event called "collision tumors". In this case we had the metastatization of 1 carcinoma to the site of the drainage of another carcinoma, but we never found the 2 histological types as close as requested to reach the definition of a collision tumor. This emphasizes the need of histological verification of different sites of recurrence when 2 or more primary cancers are known in a patient, particularly when the treatments of those primary cancers vary widely.
