Gorlin syndrome associated with small bowel carcinoma and mesenchymal proliferation of the gastrointestinal tract: case report and review of literature.

UNLABELLED: BACKGROUND AND CASE PRESENTATION: A patient with nevoid basal cell carcinoma syndrome (Gorlin syndrome) presented with two unusual clinical features, i.e. adenocarcinoma of the small bowel and extensive mesenchymal proliferation of the lower gastrointestinal tract. CONCLUSIONS: We discuss the possibility that these two features are pathogenetically linked to the formerly undescribed patient's PTCH germ line mutation.

Testicular metastasis from adenocarcinoma of the esophagus.

We report the case of a 61-year-old patient, operated on for adenocarcinoma of the esophagus in 2002, who presented in 2007 with a hydrocele and palpable mass of the right testis. Operative exploration and orchiectomy were performed. Histopathology revealed a testicular and epididymidal metastasis from the esophageal adenocarcinoma. Only a few testicular metastases have been reported from gastrointestinal cancers. No case of testicular metastasis from esophageal cancer, including Barrett's carcinoma has been reported. In most cases, the testicular tumor was accompanied by a hydrocele. Therefore, cancerous and metastatic lesions should be considered in the management of hydrocele and testicular masses.

Prostate cancer volume -- can it be predicted preoperatively?

INTRODUCTION: The prostate cancer volume (PCvol) is described as a significant predictor for tumor progression after radical prostatectomy, but its determination has not become a routine procedure yet due to high demands on technical standards, labor intensity, and costs. The objective of this study is to predict the PCvol by using common preoperative variables. MATERIAL AND METHODS: Between 1996 and 2001, 365 whole-mounted prostatectomy specimens, processed according to the Stanford protocol, were used for computerized reconstruction of the total PCvol. Widely accepted preoperative variables such as prostate-specific antigen (PSA), digital rectal examination findings, and Gleason score and grading (WHO) of the biopsy cores were correlated and analyzed for a relation to the PCvol by Spearman rho method and Mann-Whitney U test. Integrating these parameters in a multiple linear regression model, independent variables predicting the PCvol were determined, multiplied by their risk factors, and used for calculation of the estimated PCvol. In order to evaluate the precision of our results, we correlated measured and estimated tumor volumes. A nomogram was constructed, in order to visualize our results. RESULTS: Multiple linear regression analysis revealed categorized PSA, grading (WHO), and Gleason score to be independent predictors for the PCvol. The estimated PCvol ranged from 0.5 to 9.8 cm(3) and the measured PCvol from 0.02 to 53 cm(3). An identical mean value of 4.1 cm(3) was observed. The Spearman rho method showed a highly significant correlation (coefficient = 0.5) between estimated and measured PCvol (p < 0.001). CONCLUSIONS: The PCvol is regarded as a significant predictive parameter of tumor progression after radical prostatectomy, but due to its time-consuming determination, it has not become a routine procedure yet. Currently used preoperative parameters such as PSA and grading (WHO) and Gleason score of the biopsy cores do predict the total tumor volume. These results were reconfirmed by correlation analysis. Consequently, by use of our nomogram, the labor-intensive measurement of the PCvol becomes unnecessary.
