Cancer of the Prostate Presenting as Scalp and Left Supraclavicular Masses

Abstract

Prostate cancer (PCa) is one of the most fatal cancers and the second most common cancer in men worldwide. The incidence and prevalence vary in different parts of the world. In Nigeria, it is the most common cancer in men with low awareness and majority of the patients presenting with advanced disease. Rarely, this advanced disease may present clinically as supraclavicular lymphadenopathy. This is a case of a 72-year-old man who presented simultaneously with the left supraclavicular and left parietal scalp masses. The serum prostate-specific antigen was 416 ng/ml. A hard prostate was felt on digital rectal examination. Prostatic biopsy showed adenocarcinoma of the prostate. The patient had surgical castration after which both the left supraclavicular and scalp masses regressed within 10 days. There is need to entertain prostate cancer as a differential diagnosis in any middle-aged and elderly man presenting with supraclavicular and scalp masses.
