[Skin metastasis from invasive bladder tumour].

Metastatic spread of advanced transitional cell bladder carcinoma rarely involves the skin. However, the presence of a skin metastasis indicates at least microscopic dissemination of cancer cells to the liver or lung, corresponding to a poor prognosis. The authors report a new case of single skin metastasis during the course of a poorly differentiated stage pT3a N0 M0 transitional cell bladder carcinoma.

[An experience of individual and early diagnosis of prostate cancer in a Tunisian centre].

Introduction: The introduction of prostate specific antigen (PSA) and progress in transrectal ultrasound and ultrasound-guided prostatic biopsies have allowed considerable progress in the diagnosis of prostate cancer. However prostate cancer is still usually diagnosed at an advanced stage in Tunisia.

Methods: We prospectively evaluated the prevalence of localized prostate cancer in the population of a Tunisian centre during a screening programme.
