The bone represents the most common site of metastases in patients with prostate cancer (PCa). However, the proportion of men experiencing atypical metastatic sites, defined as the metastases localizing to sites other than bones or lymph nodes outside the pelvis or abdomen, is significant. For example, 10.6%, 10.2% and 9.1% of patients with metastatic PCa experience distant lymph nodes, liver, and thorax involvement, respectively. The knowledge of the distribution of metastatic sites can help provide physicians with better staging strategies, as well as follow-up protocols aimed at a prompt diagnosis of tumor recurrence after primary treatment. The involvement of atypical sites of metastases might also have a prognostic value, where individuals with visceral metastases experience shorter survival compared to their counterparts with exclusive bone involvement. Consequently, this parameter should be taken in account during the decision-making process in the treatment of PCa patients.
