Metastatic prostate adenocarcinoma presenting as a large right supraclavicular and anterior chest wall mass.

Left-sided cervical lymphadenopathy as first presentation of metastatic prostate carcinoma is not a novel observation. Here, we discuss a case of metastatic prostate primary carcinoma with an initial presentation of a right supraclavicular mass with extension into the anterior chest wall, which on radiological investigation was suggestive of a sarcomatous tumour; however, was confirmed to be pervasive metastatic prostatic adenocarcinoma. This is the second case in literature, which reports a prostatic primary cancer presenting as a right-sided supraclavicular and anterior chest wall mass. 2016 BMJ Publishing Group Ltd.
