title: [Skin metastasis as first manifestation of prostatic adenocarcinoma].
abstract: Incidence of prostate disease has seen a sudden boost over the last few years as a result of an increase in male life expectancy. Prostate carcinoma is the third most common cause of cancer mortality in Spain. Post-mortem studies reveal that this is the most prevalent neoplasia in the elderly. 30% of all males over 50 years could host malignant cells in their prostate, although only 20% of these neoplasias have clinical manifestations. Prostate carcinoma expansion occurs by local spreading, as well as lymph and blood dissemination. Local spreading to the urethra, bladder neck, trigonous and seminal vesicles is frequent. Lymph dissemination to obturating, hypogastric, iliac, presacral and paraaortic nodes is a major path for metastasis. Bone metastasis with increased acid phosphatase is the most illustrative sign of prostate adenocarcinoma expansion. Visceral metastasis occur more frequently in lungs, liver and renal glands. There is a 0.3% likelihood of skin metastasis from prostate adenocarcinoma. Considering the rareness of skin metastasis from prostate adenocarcinoma, the case reported in the present paper, first evidence of a prostate carcinoma, is even more exceptional.
