OBJECTIVE To determine if DNA quantification on fine needle aspiration (FNA) has a predictive value in cancer of the prostate. STUDY DESIGN Fifty-four patients with cancer of the prostate during the years 1979-1989 were selected; all were diagnosed by FNA. The smears were studied using image cytometry. RESULTS With the type of histogram and value of(More)
OBJECTIVE To determine if DNA quantification on fine needle aspiration (FNA) has predictive value in breast cancer. STUDY DESIGN Forty-nine patients with breast cancer were selected for this study because of their common characteristics. The smears were studied using image cytometry. RESULTS With the type of histogram and value of entropy, two large(More)
OBJECTIVE To compare the predictive value of cytologic differentiation grades traditionally used for adenocarcinoma of the prostate with the malignancy grades obtained by DNA quantification. STUDY DESIGN Of a total number of 156 cases of cancer of the prostate, 54 were selected for DNA quantification by image cytometry. They were studied cytologically,(More)
Four cases of pilomatrixoma studied by fine needle aspiration (FNA) biopsy prior to resection and histologic diagnosis were reviewed to identify the cytologic features useful in making the FNA cytodiagnosis. Cytopathology had initially correctly diagnosed two cases while misdiagnosing one as a carcinoma and one as a suspected carcinoma. The aspirates from(More)
OBJECTIVE To present a case of prostate cancer of long evolution and follow up time, in the one which has been evidenced the appearance of skin metastases at hypogastrium level, inferior extremities root and inguinal zone. METHODS Patient diagnosed of prostate cancer, treated with radical prostatectomy and followed in conferences during ten years by the(More)
OBJECTIVE To determine if DNA quantification, studied in cytologic samples obtained by fiberendoscopy, has predictive value in gastric adenocarcinoma. The survival times of patients in whom the tumor was the cause of death were considered variables of interest. STUDY DESIGN Twenty-nine patients with gastric cancer, diagnosed by cytology, endoscopy and(More)
OBJECTIVE To determine if DNA quantification, studied in cytologic samples obtained by fiberendoscopy, has predictive value in colorectal adenocarcinoma. STUDY DESIGN Thirty patients with colorectal cancer diagnosed by cytology, endoscopy and microbiopsy, were selected. The study covered > 10 years. Smears were stained with progressive hematoxylin and(More)
Papillary neoplasms of the breast include a wide spectrum of mammary lesions. The differential diagnosis of benign and malignant lesions can be problematic not only cytologically, but also histopathologically. Aspiration smears can demonstrate that cytological differentiation is feasible. A retrospective study of 30 cases of papillary tumour of the breast,(More)
Mammary hamartoma is a breast lesion rarely reported by fine-needle aspiration cytology (FNAC). We report on our experience of FNAC in nine cases confirmed by biopsy. We searched hospital case files for mammary hamartoma or similar lesions (fibrolipomas, lipomas, fibromas, etc.), and cases included were only those in which both FNAC and a histopathological(More)
