 Abstract
 PDF
- Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare type of kidney tumor that has only been recently described. Furthermore, a case of MTSCC associated with a simultaneous lung cancer in the same patient has never been reported in the literature. In this paper, we describe a kidney tumor that was detected during staging work-up in a 72-year-old lung cancer patient. The kidney tumor was removed and shown to exhibit histological and immunophenotypic features of MTSCC, completely distinct from the pulmonary adenocarcinoma. In addition, this case was unique because it was characterized by neuroendocrine differentiation as well as p53 and Ki-67 overexpression in tumor cells. Therefore, we report a case of MTSCC diagnosed in a patient with pulmonary adenocarcinoma and describe the detailed histologic and immunohistochemical features of MTSCC.

- BACKGROUND
:Prostatic adenocarcinoma makes up about 2% of the total cancer incidence and cancer death in Korean men, but the incidence of this malady is continuously increasing.
So far, there have been only a few studies describing the pathologic characteristics of the prostatic adenocarcinoma in Korean patients. In this study, we analyzed 83 radical prostatectomy specimens by using mapping analysis to discover the clinico pathologic characteristics of Korean prostatic adenocarcinoma.
METHODS
The resected prostates were serially sectioned and embedded for histologic mapping. The clinico pathologic findings, including the Gleason score, tumor size, prostate intraepithelial neoplasia (PIN) and tumor invasion to the surrounding tissues, were examined.
RESULTS
The mean values were as follows: age, 64.1+/-6.6 years; serum prostate specific antigen (sPSA), 16.6+/-16.2 ng/mL; tumor volume, 22.3+/-22.4%; tumor size, 2.2+/-1.2 cm; and Gleason score, 6.9+/-0.9. The rate of high grade PIN was 79.7%. The Gleason score, tumor extent and T stage were statistically correlated (p<0.05).
CONCLUSIONS
Some prognostic factors such as sPSA and the Gleason scores showed significantly lower levels compared with those of the previous studies on Korean prostate adenocarcinoma (16-36 ng/mL vs 16.6 ng/mL and 7.3-7.7 vs 6.9, respectively). Although these values are still higher than those of the western studies, this study implies that the early detection of prostate adenocarcinoma is increasing in Korea.
