Adenomatoid tumor of the epididymis: immunohistochemical study of 8 cases.

The immunohistochemical characteristics of 8 adenomatoid tumors of the epididymis are reported. Using the peroxidase antiperoxidase technique and the avidin-biotin complex method, antibodies against carcinoembryonic antigen, factor-VIII-related antigen and keratin were tested. In agreement with previous findings strong cytoplasmic staining for keratin was seen in all the tumors, whereas the factor-VIII-related antigen and carcinoembryonic antigen were absent. These results suggest a mesothelial origin of the adenomatoid tumor.

Urine cytology in the detection of renal adenocarcinoma.

Whereas urine cytology has proved to be of considerable diagnostic value for nonpapillary urothelial carcinoma, carcinoma in situ, and high-grade urothelial tumors, controversy has arisen over the accuracy of cytology in the diagnosis of renal neoplasms. To establish the reliability of urine cytology as a detection technique, 436 urine specimens from 59 patients with histologically proven renal adenocarcinoma were examined. Malignant cells in urinary sediment were found in 121 (27.75%) specimens from 31 (52.54%) patients. Seven of 20 (35%) patients with Stage I tumor showed neoplastic cells in 16 (16.5%) of 97 urinary samples. Positive cytologic features were found in 36.9% of 84 urinary specimens from 7 (50%) of 14 patients with tumors smaller than 5 cm. Using only imaging methods, the renal neoplasm was diagnosed in 58 (98.3%) cases. Urine cytology is, therefore, of little value in the diagnostic evaluation of known renal masses and in the detection of early-stage disease. In the current series there was not a single case with positive cytologic findings in which radiology did not reveal the tumor. The cytologic examination of the urinary sediment is unreliable in the diagnosis of radiologically unresolved cases of renal neoplasms. In 15 patients (44%) who had cancer cells in the urine the neoplasm had not invaded the renal pelvis. In 36% of patients with negative urine cytologic findings the renal pelvis was involved by renal adenocarcinoma. In the current study the desquamation of neoplastic cells in the urinary stream did not depend on tumor invasion of the renal pelvis. Based on the assumption that the primary objective of a screening procedure is to achieve an adequate sensitivity for early detection of disease, the results led the authors to conclude that the use of urine cytology as a possible screening test of renal adenocarcinoma is futile. Factors in the current study that diminished the practical value of cytologic examination of urinary sediment included the large number of specimens without malignant cells and the insensitivity of the procedure in diagnosing early renal adenocarcinoma of limited extent. Although this is the largest series reported, the number of cases considered was limited and further detailed studies are mandatory to definitively clarify the value of urine cytology in detecting renal adenocarcinoma.

Aspiration cytology in the staging of urologic cancer.

Knowledge of the status of the pelvic lymph nodes is vital for accurate staging and adequate treatment of patients with urologic cancer. Noninvasive techniques for assessing the lymphatic spread of urologic neoplasms have proved to be of limited value. Bipedal lymphangiography and percutaneous fine needle aspiration cytology under fluoroscopic guidance were performed for staging purposes in 71 patients with clinically localized bladder, prostatic and penile cancer from 257 nodal chains. The overall diagnostic accuracy was 93% and the correct aspiration of 186 lymph nodes was surgically confirmed. There were 11 (6%) false-negative biopsy results and no false-positive diagnoses. Aspiration cytology is a safe, well tolerated, accurate, and rapid method of determining the presence of metastatic disease in lymphangiographically visualized pelvic nodes. In the management of prostatic carcinoma, positive cytologic results are diagnostic of nodal metastatic involvement and spare the patients unnecessary surgical staging. Negative cytologic findings may be considered diagnostic of localized disease in the patients with well differentiated prostatic carcinoma (2-4 Gleason's sum). Since most surgeons are reluctant to perform a staging lymphadenectomy in the management of invasive bladder carcinoma, aspiration cytology can provide accurate staging, thus permitting an appropriate treatment plan. In patients with carcinoma of the penis, a positive aspirate permits an early and even curative lymphadenectomy in cases with clinically negative but pathologically positive nodes.

Primary osteosarcoma of the uterine corpus. Report of a case and critical review of the literature.

Uterine osteosarcoma represents an extremely rare pure heterologous sarcoma of the uterus. In the present case osteosarcoma occurred primarily in the uterine cavity of a 56-year-old woman. The tumor was anaplastic and the presence of different proliferative patterns caused differential diagnostic problems with various malignant tumor types. The osteoid features of extracellular matrix were demonstrated by electron microscopy. Clinical and pathological features of previously reported cases of uterine osteosarcoma are critically reviewed.

Experience with modified Chiba needle in staging of genitourinary tumors.

The features of a new needle used in the percutaneous pelvic node fine-needle aspiration biopsy in 56 patients with urologic neoplasms are described. The side openings on either side of the needle walls and the bevel angle lowered to 15 degrees provide excellent penetration and aspiration ability. Representative specimens were obtained from all patients, and the accuracy of aspiration biopsy results in determining true stage of disease was 94.64 per cent. These data provided sufficient evidence of the efficiency of our needle to recommend it for use in TNM classifications of urologic tumors.

Aspiration cytology of simultaneous bilateral adrenal metastases from renal cell carcinoma. A case report and review of the literature.

We report the computerized tomography and ultrasound-guided aspiration cytology results in the first case of renal cell carcinoma with bilateral adrenal involvement. The adrenal metastases were evident clinically 6 years after radical nephrectomy and were treated successfully by an operation. Aspiration cytology under computerized tomographic and sonographic guidance is an excellent procedure to evaluate enlarged adrenal glands in patients with renal cell carcinoma or other malignant neoplasms.

Comparative study of lymphography and aspiration cytology in the staging of prostatic carcinoma. Report of 35 cases with histological control and review of the literature.

Accurate staging of prostatic carcinoma is essential in determining the prognosis and establishing the most adequate therapy of the disease. Lymphography is the most widely used method in staging prostatic carcinoma but shows false-positive rates varying up to 58% and false-negative rates varying from 11 to 66%. Aspiration biopsy was proposed to enhance the reliability of lymphography. In our study we performed transcutaneous aspiration biopsy of the pelvic nodal chains in 35 patients with clinically localized prostatic carcinoma using a long-beveled side-holed modified Chiba needle. 124 nodal chains were punctured and malignant cells were found in 26 aspiration biopsies of 15 patients. In determining the true stage of the disease, aspiration cytology and lymphography showed accuracy of 91 versus 57%; sensitivity of 83 versus 67% and specificity of 100 versus 47%, respectively. Positive cytologic findings are conclusive for stage D disease, while negative cytology may be accepted as definitive only when the neoplasm is well differentiated or the Gleason sum is 2-3-4. Combined use of lymphography and aspiration cytology permits surgical staging to be limited to those patients with undifferentiated neoplasm, intermediate or high Gleason sum (5-10) and negative cytology.

[The role of transcutaneous fine-needle aspiration biopsy of the regional lymph nodes in the management of cancer of the penis].

Knowledge of the status of the regional lymph-nodes is essential for establishing the stage and the optimal treatment of carcinoma of the penis. Lymphadenectomy cannot be performed routinely because of its morbidity (30-50%) and mortality. Various noninvasive procedures such as lymphography, T.A.C. and echography have been proposed but are of limited diagnostic value because of the unacceptable frequency of the false positive and false negative findings. The transcutaneous fine-needle aspiration biopsy of the draining nodes visualized by lymphography is an innocuous, non invasive, excellent procedure, alternative to staging surgery in determining or excluding the presence of the nodal metastases. The positive cytology is conclusive of stage III and implies early, sometime, curative lymphadenectom. If the aspirate is abundant and largely representative the negative findings may also be considered to indicate the reactive nature of the lymphadenopathy.

Spindle cell tumours of the skin of debatable origin. An immunocytochemical study.

Twelve cases of malignant spindle-cell and sarcomatoid tumours of the skin of debatable nature were studied by immunocytochemical methods, using four antisera which might help contribute to resolution of the problems. The initial diagnosis made on structural grounds was confirmed by immunocytochemistry in six of eight cases in which a specific diagnosis had been made (one melanoma, three squamous carcinomas and two atypical fibroxanthomas). One case, initially regarded as AFX was reclassified as a squamous carcinoma, while a further case of possible AFX could not be confirmed by immunocytochemical study. Of the four cases in which structural examination was inconclusive, two were identified as squamous carcinomas and one as a melanoma by virtue of tumour markers. The fourth case was an intriguing actin-rich tumour of uncertain nature. Immunocytochemistry, despite certain limitations, has a valuable role to play in the analysis of the problematic spindle-cell malignant and pseudomalignant tumours of the skin.

Percutaneous lymph node aspiration biopsy and tumor grade in staging of prostatic carcinoma.

Percutaneous fluoroscopy-guided fine-needle aspiration biopsy was performed for staging procedures in 31 patients with clinically localized carcinoma of the prostate and showed overall accuracy of 93.54%, with a false-negative rate of 6.46%. The Gleason grading system was found to be highly accurate in predicting the absence or presence of nodal metastases in low- and high-grade tumors (Gleason's sums 2, 3, or 4, and 8, 9, or 10). The combination of pelvic node biopsy aspiration and tumor grade can result in a very accurate prediction of nodal involvement, and may spare patients a staging lymphadenectomy or even an unnecessary radical operation.

Squamous cell carcinoma with sarcoma-like stroma of the nose and paranasal sinuses: report of two cases.

Two cases of squamous cell carcinoma with sarcoma-like stroma of the nose and paranasal sinuses are described. To the best of our knowledge, this is the first report of such a localization for this tumour type. Keratin was localized by immunocytochemistry in the epithelial cells, as well as in occasional stromal-like elements. The importance of distinguishing these tumours from morphologically similar neoplasms is emphasized in view of their different therapeutic approach.

Association of xanthogranulomatous pyelonephritis with small renal cell carcinoma. Case report and review of the literature.

A case of xanthogranulomatous pyelonephritis associated with 'small' renal carcinoma is presented. The urinary sediment showed atypical cells, suspect of malignancy. The renal neoplasm measured only 1.5 cm, had the typical papillary configuration of a 'small' renal carcinoma and was composed of atypical cells with finely granular cytoplasm and hyperchromatic nuclei. The xanthogranulomatous pyelonephritis was a primary lesion, spacially separate one from the other. The clinicopathological features of reported examples of coexistence of these diseases have been reviewed.
