- Signet ring cell carcinoma is a rare type of mucinous adenocarcinoma of the uterine cervix. To the best of our knowledge, there is no report on cytologic findings of primary signet ring cell carcinoma of the uterine cervix in the literature. Recently, we experienced two cases of signet ring cell carcinoma of the uterine cervix. The finding of characteristic signet ring cells on cervicovaginal smear led to the diagnosis of signet ring cell carcinoma. However, primary signet ring cell carcinoma could not be cytologically distinguished from more common metastatic tumor. Therefore, diagnosis rests upon the recognition of signet ring cells and the absence of signet ring cell carcinoma elsewhere.

- Heart transplantation was first performed in 1967. It is now regarded as a well-established treatment modality for end-stage cardiac diseases. Once the transplantation is performed, endomyocardial biopsy(EMB) is the examination of choice in monitoring the transplanted heart. We analyzed the pathological findings of follow-up EMB of 6 heart transplant patients. All patients have been suffered from severe heart failure. Four patients were adult male and two were adult females. All the hearts, except for one, displayed characteristic features of dilated cardiomyopathy. The remaining heart was diagnosed as having giant cell myocarditis. Post-transplantion EMBs were performed according to the protocol and standard cardiac biopsy grading of ISHT (1990). The standards were applied for grading of cellular rejection. In five patients, there were one or two episodes of biopsy proven acute rejection, grade II or IIIA without any clinical symptoms of rejection.
Immediate "pulse therapy" was performed and follow-up biopsies were done. All episodes of rejection were cleared in subsequent biopsies. All patients are doing well without evidence of cardiac problem. The postoperative monitoring of acute rejection is critical since clinical signs of rejection are usually absent. At present, EMB is regarded as the most reliable method for diagnosis and grading of acute rejection and is an efficient guide to the monitoring of the cardiac recipients. Our experience of post-transplantation EMB corresponds with previously published reports.

Abstract

- There has been a marked increase in the utility of aspiration cytology for pathologic diagnosis. It may be applied to any kinds of organs and substitutes surgical biopsy. Because of the high risk of complication and difficulties in localization, aspiration cytology in the central nervous system(CNS) has been used with less frequency compared to other sites. However, with the advent of sophisticated imaging instruments, aspiration cytology of lesions in the CNS is being used increasingly.
Cytologic features of the CNS neoplasms were quite similar to those of histology except one spindle cell tumor.
Reviewing various CNS neoplasms, it appears that cytology may be a useful diagnostic method.
