A case of suprapubic cutaneous metastasis from prostatic adenocarcinoma

Background: Prostate cancer is a commonly diagnosed and treated malignancy, although it rarely presents with cutaneous metastases. In this case report, we describe the diagnosis and treatment with radiotherapy and endocrine therapy of a patient who presented with suprapubic cutaneous metastases secondary to prostate cancer. Case report: A 77-year-old man presented with a six-month history of an asymptomatic suprapubic mass. A skin biopsy of the mass was performed and neoplastic cells consistent with metastatic prostatic adenocarcinoma were seen according to immunohistochemical techniques. Recieving pelvic radiotherapy and endocrine therapy (bicalutamide and goserelin), the patient recovered well and discharged. Discussion: In this report, a rare metastatic manifestation of a common malignancy is presented. Due to the low incidence, the majority of urologist and dermatologist are difficult to diagnose. An accurate diagnosis often requires vigilance, and confirmation by immunohistochemistry. Treatment after diagnosis is mainly dependent on the treatment of primary disease: endocrine therapy, aiming to maximal androgen blockade.
