Quaint metastasis and markedly elevated prostate-specific antigen: An unusual manifestation of prostate cancer

Abstract

Prostate cancer is one of the most common malignancies in males globally with records of approximately 1.6 million diagnosis and over 0.36 million deaths annually. The discovering and subsequent clinical application of the prostate-specific antigen (PSA) improved the diagnostic rates. Values of PSA (a tissue-specific marker) persistently greater than 4 ng/mL are regarded as abnormal hence histological studies are often required to confirm malignancy. Adenocarcinomatous cells, commonly osteoblastic, typically metastasize to the lumbar region via the veins of Batson. We report a case of prostatic cancer in a 69-year-old Nigerian with markedly elevated PSA, thoracic spine, and pelvic metastasis.
