title: Metastatic Prostate Cancer Presenting as Lower Extremity Soft Tissue Mass: A Rare Case Presentation.
abstract: A 69-year-old homeless African American male with prostate cancer diagnosed 2 years prior presents a large mass in the right thigh. An evaluation of the patient revealed a prostate-specific antigen of 9362 ng/mL. Biopsy of the leg mass was performed and final pathology indicated metastatic adenocarcinoma of the prostate. Although metastatic prostate cancer presents most commonly in bone, lymph nodes, lungs, and liver, metastatic disease presenting as a soft tissue mass is extremely rare (Bubendorf et al, 2000; Molenaar et al, 1996; Ward and Bourken, 1984). The advent of screening with prostate-specific antigen has led to earlier diagnosis of lower-grade disease, yet underserved populations continue to present with aggressive and morbid disease (Winer et al, 2014).
