Abstract
Thermography is useless for diagnosis of cutaneous malignant melanomas (CMM). In fact, false negative thermograms (29.9 %) are much more numerous than clinically suspicious cases. Thermography is useless for follow-up of CMM. False-negative and false-positive thermograms of metastatic lymph nodes, subcutaneous nodules and removal site of CMM are much too numerous.

Abstract
Modern immunohistochemical techniques allow a detailed study of the lymphatic system in many organs and areas of the body. We performed an in-depth study on lymphatic vessels of the ileal and colonic mesenteries, together with the greater omentum where they appear particularly numerous and mainly represented by capillaries interconnected among themselves and with lymph nodes. The capillary wall consists of a fine single sheath of endothelial cells wrapped around by a subtle collagen membrane and deprived of valves. The progression of lymph flow is promoted by external forces acting on the capillary walls. Only at the mesenteric roots can pre- and post-lymph nodal collector vessels be observed. Our observations help to explain different patho-physiological correlations and the possible presence of skip lymph node metastases.

Abstract
In the dermatopathological practice, there is a group of atypical melanocytic lesions with borderline histological features between benign simulants and malignant melanoma (MM), due to conflicting diagnostic criteria and inter-observer disagreement. In these cases, the dermatopathologist is authorized to seek consult with an established expert in the field, but even the most experienced specialist may not be sure about the correct diagnosis and the subsequent biological behavior. There is general consensus among qualified dermatopathologists that can be helpful to insert these ambiguous cases into two diagnostic categories: SAMPUS (Superficial Atypical Melanocytic Proliferations of Unknown Significance) and MELTUMP (MELanocytic Tumors of Uncertain Malignant Potential). According to the conception of MM progression through two phases, the radial growth phase and the vertical growth phase, it is possible to identify a novel subtype of thin melanoma (THIM) with uncertain metastatic potential, due to the presence of extensive regression ( 75% of the lesion volume), which we here define with the acronym THIMUMP (THIn Melanoma of Uncertain Metastatic Potential) for the first time in literature.Key words: malignant melanoma - thin melanoma - histology.

Abstract
Fetoplacental hydrops is the final stage of several pathological conditions in which the placenta and umbilical cord become edematous and the fetus develops an anasarcatic state characterized by an excessive accumulation of extravascular fluids in at least two serous cavities of the body. It is a common histological finding of stillbirth, characterized by the appearance of markedly edematous villi, suggesting an increased interstitial fluid accumulation. The recent improved knowledge of lymphangiogenesis and the availability of monoclonal antibodies selectively labeling lymphatic endothelium lead to the hypothesis that villous edema is essentially a lymphedema from defective lymphatic function following inadequate villous blood circulation. Lymphedema is a morphologic phenotype found by our research group in a 24-case series of stillbirths from different morbid conditions such as chromosomal aberrations, congenital malformations, inherited hemoglobinopathies, and prolonged perinatal severe anoxia. Unlike long-lived organs, the placenta is devoid of innervation by the autonomic nervous system; therefore, the vascular tone regulation and the peripheral perfusion are modulated by the expression of the angiotensin converting enzyme (ACE) in the vascular endothelia. This finding may suggest to the clinician to search for a more suitable therapy in case of mother's hypertension during pregnancy.

Abstract
INTRODUCTION The term superficial atypical melanocytic proliferations of uncertain significance (SAMPUS) is used to resolve discordance in diagnosis of "thin" melanocytic lesions. Melanocytic tumours of uncertain malignant potential (MELTUMP) is the descriptive term for an ill-defined group of dermal melanocytic tumours that exhibit features indicative of possible malignancy. We report our experience of collaboration with two leading international consultant pathologists in the diagnosis of melanoma in order to facilitate the practical application of the term SAMPUS and MELTUMP. METHODS Twenty-seven cases of melanocytic lesions with interpretative problems were sent for consultation to Expert #1 (15 cases) and Expert #2 (12 cases). RESULTS Two cases of MELTUMP and two cases of SAMPUS were diagnosed by Expert #1; three cases of MELTUMP and two cases of SAMPUS were diagnosed by Expert #2. Diagnosis was performed with H&E and molecular studies were not performed. DISCUSSION Both experts included MELTUMP or SAMPUS atypical, ambiguous melanocytic lesions and melanomas. The diagnosis of SAMPUS and MELTUMP by consultant pathologists reflects the difficulty of classification with accuracy lesions that showed histological features of various atypical tumours or malignant melanoma. In these cases, biological potential may be established with molecular studies.

Abstract
OBJECTIVES The clinical-pathological features of squamous cell carcinoma (SCC) arising in cutaneous cysts has been studied. METHODS We report two cases of SCC arising in epidermal cyst (EC) and one case in human papilloma virus associated cyst (HPAC). RESULTS In the first EC case, a 88-year-old man presented a cystic right zigomatic mass. Histopathology revealed a cyst lined by stratified squamous epithelium in continuity with invasive keratinizing SCC. In the second EC case, a 96-year-old man presented with a 1.5 x 1 cm nodular lesion localized at the helix of the right ear. Histopathology showed the typical cystic wall of an EC with transition to invasive keratinizing SCC. Finally, a 86 year-old woman presented with a perineal cystic nodule 1.5 cm in diameter. The wall showed varying degrees of papillomatosis, hypergranulosis, parakeratosis with dysplastic and koilocytic changes. Areas of in situ and invasive SCC were found. Human papillomavirus (HPV) 16 was detected. CONCLUSIONS SCC arising in an EC may be diagnosed only with the support of an accurate histopathological documentation in order to exclude mimics. Regarding HPAC, the site, the malignant transformation and the finding of HPV 16 type, may be considered features of an extraordinary rare case.

Abstract
Carcinoid tumour is an endocrine neoplasia described for the first time in 1888 and rarely observed in the extrahepatic bile ducts. Gallbladder carcinoid tumour was first reported by Joel in 1929. An endoluminal gallbladder lesion, with a bizarre echogenicity, and a mass in the upper pole of the left kidney were found in a 27 year-old man. The patient underwent a cholecystectomy with partial hepatectomy and a polar renal resection. Histological examination revealed a typical gallbladder carcinoid tumour with regional lymph nodal metastasis and a renal cell carcinoma, with morphological and histochemical features of the chromophobe type. This is a distinctive, rare variant, often described in the literature in association with other neoplastic and non-neoplastic diseases. To our knowledge, this is the first report of gallbladder carcinoid tumour with an unexpected aggressive behaviour in a very young patient, with concurrent renal cell carcinoma, chromophobe variant.

Abstract
Ovarian oxyphilic Sertoli cell tumor is a rare neoplasm (only three cases were reported in literature). Sometimes the rarity itself of a lesion raises some problem in the diagnostics, especially if the case is send to several consultants. An unusual case of ovarian neoplasm came to our attention, and we sent some slides of the case to two well known referees of different Departments of Pathology. Pathologist 1 made a diagnosis of endometrioid adenocarcinoma, while Pathologist 2 made the diagnosis of oxyphilic Sertoli cell tumor. He sends the same slides to Pathologist 1, who confirmed his diagnosis. The two different diagnosis set different managements of the lesion for the clinician, but overall they set the pathologist who requested the consultation in a difficult position. In fact, when a pathologist sends to two experienced consultants a case, he really thinks to solve definitely the case itself. Unfortunately, sometimes it does not happen.

Abstract
Balanitis xerotica obliterans is a term applied to a chronic inflammatory disease of the glans penis and prepuce. The symptoms are usually a sudden FIMOSI, a reduction of the sensibility of the glans, a stenosis of the uretreal meatum and dysuria. The disease was thought in the past as a rare pathology, whereas recent reviews of the literature showed that its frequency is quite high. We present a case of a male patient who presented to the urological department of the Guastalla hospital for a sclerosing lesion of the glans. The lesion were biopsied, and the histological picture showed hyperkeratosis of the epithelium with atrophy of the malpighian layer, oedema of the upper dermis and inflammatory infiltrate of medium derma (lymphocytes and scattered histyocites). The early diagnosis and the following treatment of this pathology are very important for its resolution, although the surgery is not always needful (often it is sufficient the clinical diagnosis). The surgical excision shall be used always in case of differential diagnosis with a neoplastic and/or atypical or uncertain lesions (penis carcinoma).

Abstract
We describe the clinical and neuropathological findings of three unrelated autopsy cases of MELAS harboring the A3243G transition in the mitochondrial DNA (mtDNA). Using immunohistochemical techniques, we studied the expression of several subunits of the respiratory chain in various brain regions from the same cases. In all three cases there was a reduced immunocytochemical staining for mtDNA-encoded subunits of the respiratory chain, confirming the presence of a defective mitochondrial protein synthesis in this disease. Mitochondrial abnormalities were mostly confined to multiple areas of different size and shape, in agreement with the focal character of the brain pathology in MELAS, and were most prominent in the cerebral cortex, providing a morphological contribution to the explanation of the cognitive regression of the patients. Immunoreactivity for mtDNA-encoded subunits was reduced in the walls of many pial and intracerebral arterioles of different brain regions but there was no clear correlation between territories of affected vessels and distribution of the histological and immunohistochemical lesions. Cerebral focal lesions in MELAS might have a metabolic nature and several pathogenetic mechanisms might be involved in the genesis of stroke-like episodes when there is a local increased ATP demand.

Abstract
BACKGROUND Incidence of adenocarcinoma of distal oesophagus and gastric cardia, probably arising from areas of intestinal metaplasia, has been increasing rapidly. AIMS To define prevalence of intestinal metaplasia of distal oesophagus, oesophagogastric junction and gastric cardia and to evaluate potential associated factors, by means of a prospective multicentre study including University and teaching hospitals, and primary and tertiary care centres. PATIENTS Each of 24 institutions involved in study enrolled 10 consecutive patients undergoing first-time routine endoscopy for dyspeptic symptoms. METHODS Patients answered symptom questionnaires and underwent gastroscopy Three biopsies were taken from distal oesophagus, oesophago-gastric junction and gastric cardia, and were stained with haematoxylin and eosin. Specimens were also evaluated for Helicobacter pylori infection. RESULTS A total of 240 patients (124 male, 116 female; median age 56 years, range 20-90) were enrolled in study. Intestinal metaplasia affected distal oesophagus in 5, oesophago-gastric junction in 19 and gastric cardia in 10 patients. Low-grade dysplasia was found at distal oesophagus and/or oesophago-gastric junction of 3/24 patients with intestinal metaplasia vs 2/216 without intestinal metaplasia (p<0.05). A significant association was found between symptoms and presence of intestinal metaplasia, regardless of location, and between Helicobacter pylori infection and intestinal metaplasia at oesophago-gastric junction. CONCLUSIONS Intestinal metaplasia of distal oesophagus, oesophagogastric-junction and gastric cardia is found in a significant proportion of symptomatic patients undergoing gastroscopy and is associated with dysplasia in many cases. Although prevalence of dysplasia seems to decrease when specialized columnar epithelium is found in short segment, or even focally in oesophago-gastric junction, these small foci of intestinal metaplastic cells may represent source of most adenocarcinomas of cardia.

Abstract
Telemetric, intraoperative frozen section diagnosis may be a useful tool for rural hospitals lacking an in-house pathology service. As a part of a Health Ministry Project on Telemedicine in Trentino (northern Italy), we developed a static telemicroscopy system (STeMiSy). This system connects the rural hospital of Cles with the main hospital of Trento. The two hospitals are 40 kilometers apart, and the road connecting the two towns runs across the mountains and has a heavy traffic. Before putting STeMiSy into practice, we tested the software and hardware on the LAN of the regional hospital system, by connecting the pathology services of Trento and Rovereto (20 kilometers apart). This test phase lasted three months and has not revealed major problems in the LAN nor in the robotic microscope, which was always precise and reliable. The quality of the images and the speed of transmission were largely sufficient for intraoperative frozen section diagnosis. Minor details of the histological slides were not always appreciated on the panoramic view. This loss of some details may be due to the quality of the panoramic view, which represents the 'surfing map' to read the cases. Nevertheless, the recognition of these small details was not so relevant as to change the surgical approaches. An audioconference system, utilizing the same transmission channel, not only slightly slowed the transmission but also caused some instability to the system. The audioconference system has therefore been abandoned, and when necessary we used the normal telephone. Macroscopic images of the whole surgical specimen, the surgeon's responsibility for the sampling, good technical quality of the slide, and good training will allow us to perform remote frozen section diagnosis in the absence of the pathologist. We believe that the main, and probably only, difficulty for this approach is not of a technical nature, but reflects the pathologist's resistance to making a remote video diagnosis.

Abstract
The monofunctional furocoumarins, the 6-methylangelicins, were tested for their antiproliferative activity with various animal models and for genotoxicity in micro-organisms and in mammalian cells. The most active compound was 6,4,4'-trimethylangelicin, which showed a high antiproliferative effect and reduced genotoxicity in comparison with 8-methoxypsoralen (8-MOP). Some of these compounds were also tested clinically by topical application on 17 patients with psoriasis. They appeared to be more active than 8-MOP in clearing psoriasis without inducing skin phototoxicity. The methylangelicins also caused skin pigmentation.

Abstract
In patients with known cancer, especially in cases of genitourinary cancer, thickening of the ureteral wall secondary to irradiation, chemotherapy, or surgery may make the diagnosis of metastasis, recurrence or persistence of malignancy very difficult. Since it is impossible to determine by radiologic imaging methods, whether the stricture is benign or malignant in nature, exploratory laparotomy with direct tissue biopsy remains the only procedure for an accurate diagnosis of the cause of the obstruction. As such surgery carries a significant level of morbidity, nonaggressive diagnostic techniques should be considered. The authors investigated the usefulness of aspiration biopsy cytology under fluoroscopic guidance in establishing the true nature of ureteral stenosis in 15 patients with known primary malignancy, who had previously been treated with surgery, radiotherapy, or chemotherapy. The etiology of the primary malignancies were uterine cervix (six), bladder (two), prostate (two), uterine corpus (two), pancreas (one), stomach (one), and rectum (one). Thirteen patients had metastatic ureteral involvement. There were no false-positive or false negative cytologic findings, therefore diagnostic accuracy was 100%. In the authors' experience the success of aspiration biopsy cytology depends on the skill and experience of the physician performing the procedure. The results of this study and review of the literature demonstrate that aspiration biopsy cytology is an accurate, minimally invasive means for correct cytologic diagnosis of ureteral strictures which can complicate cancer, without resorting to more aggressive diagnostic procedures.

Abstract
The relationship between cutaneous malignant melanoma (CMM) and the colour of skin, hair and eyes, the extent of sun exposure and reaction to it, education, and the occurrence of skin neoplasms in patients and their families was evaluated in a case-control study of 103 cases of CMM and 205 control subjects hospitalized for acute conditions other than malignant or hormonal disease. A significantly higher risk was associated with fair skin as compared to dark/medium skin (RR = 4.0; 95% CI: 1.5-10.5) and positive family history for CMM (RR = 8.1; 95% CI: 1.0-200.9). CMM seemed to occur more frequently, but not significantly so, in individuals with brown or blond hair, higher education and clinically diagnosed dysplastic naevi. Outdoor occupation and heavy sun exposure in the last 20 years seemed to increase the risk of CMM in sun-exposed sites but to be negatively associated with CMM in normally unexposed sites.

Abstract
Aspiration biopsy cytology is an accurate, safe, innocuous alternative to excisional biopsy in diagnosing the nature of concomitant superficial nodules or lymphadenopathy in patients with known cutaneous malignancy. In patients with penile cancer, aspiration biopsy cytology may avoid the morbidity (30-50%) and mortality (3%) of groin dissection staging. A positive aspirate is conclusive of Stage III tumor and, in patients with occult nodal metastases, may lead to early curative lymphadenectomy. In the present study of 28 patients with known cutaneous malignant melanoma, the aspiration biopsy cytology of 31 superficial nodules resulted in a cytologic diagnosis of metastasis in 29 nodules from 26 patients. In the management of patients with known melanoma, the positive cytology of superficial nodules is conclusive of metastatic disease and requires an accurate radiologic study to establish or exclude disseminated disease. Surgical removal of a metastatic superficial nodule is indicated when the lesion is considered localized disease and the patient, having been accurately examined, is determined to be apparently free of disease in other sites and organs. When systemic diffuse melanoma is found, the excision of metastatic superficial nodules is unnecessary. Positive aspiration cytology may avoid risk from ill-judged surgical procedures and indicate appropriate palliative treatment of the disease.

Abstract
Appropriate management and prognosis of patients with penile carcinoma depends on an accurate knowledge of the regional node status. The usefulness of clinical and radiologic examinations in detecting the nodal spread of the disease is limited by the high rates of false-positive and false-negative results. On the other hand, routine or prophylactic lymphadenectomy is associated with 30% to 50% of the major morbidity and 3% of the mortality rate, so that caution is advisable for its use in patients with disease-free nodes. Even bilateral sentinel lymph node biopsy, as proposed by Cabanas, does not warrant an adequate selection of patients candidates to surgical treatment. The role of aspiration biopsy cytology in the management of penile carcinoma was evaluated in a study of 29 cases from the authors' institutions. Aspiration under fluoroscopic or computed tomographic guidance was performed using a 22-23-gauge Chiba needle. The accuracy of aspiration biopsy cytology in identifying the true stage of the disease was 100%. On histologic control, only one node contained malignant cells that were not detected by aspiration biopsy cytology, but this finding did not alter the stage of the patient. Positive cytology is conclusive of Stage III disease and, in this case, a curative lymphadenectomy may be attempted. Negative aspirations do not warrant the absence of metastatic nodal involvement as can be seen in two patients in this series. In such cases, however, a policy of "wait and watch" may be adopted, with repeated aspiration biopsies or surgical biopsy of the sentinel node area.

Abstract
The diagnosis and removal of precursor and early lesions is the only method to improve the prognosis and survival rate in malignant melanomas of the skin since the aetiology of the disease is unknown and treatment ineffective when the neoplasm is diagnosed at an advanced stage. A campaign for the prevention and early diagnosis of melanoma is based on the health education of the entire population with the distribution of illustrative material that by teaching people to examine their skin will show up suspicious pigmentary lesions that can be examined and removed by the dermatologist. Thin melanoma is always curable when removed and constitutes the basic tumour to be described to the public as it is easily identified and has constant, typical features. Among the precursors the most interesting lesions is the sporadic or familial dysplastic nevus despite the controversy over its pathogenic significance and morphological aspect. The other pigmentary neoplasias (congenital and acquired nevus) only must to be removed when they present changes resembling thin melanoma.

Abstract
Aspiration cytology is a simple, accurate and minimally invasive procedure in staging urological neoplasms. Percutaneous fluoroscopy-guided fine needle aspiration biopsy of 99 lymph nodes was performed in 30 patients with bladder carcinoma and 62 lymph node chains were evaluated. Aspiration biopsy is more accurate and specific than lymphography in the pre-operative staging of the neoplasm and represents a useful diagnostic procedure for the staging of bladder carcinoma.

Abstract
Spindle cell squamous carcinoma is a highly malignant neoplasm, characterized by a biphasic appearance, due to the presence of a diffuse proliferative pattern of pleomorphic spindle cells with extremely rare foci of conventional squamous cell carcinoma. Epithelial markers in eight cases of spindle-cell squamous carcinoma of the head and neck region were studied by immunocytochemistry. Epithelial membrane antigen and cytokeratin resulted strongly positive in the spindle cells of the sarcoma-like areas demonstrating the epithelial nature of the neoplasm. In 6 of our patients who later died from widespread metastases, the neoplasm had poor prognosis with a mean survival rate of 14.7 months.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

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.

Abstract
The role of fine needle aspiration (FNA) biopsy in the evaluation of lymphoreticular disorders involving the lung and mediastinum was evaluated in a study of 16 cases from the authors' institutions. The cytologic material from these cases was reviewed, and the original cytologic interpretations were compared to the tissue diagnoses, with the overall accuracy of the cytologic interpretation evaluated. There were no false-positive diagnoses of malignancy in this series. A definite diagnosis of malignant lymphoma was most readily made in those cases in which the lymphoma was of the large-cell type. Small-cell and mixed large-cell and small-cell lymphoid proliferations were less able to be definitively interpreted, with pseudolymphoma presenting particular difficulty. The results support the conclusion that FNA biopsy can be useful in evaluating these lesions but also emphasize the fact that accurate diagnosis requires correlation of cytologic, clinical and laboratory data.

Abstract
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.

Abstract
The cytologic findings in the urinary sediment of 13 patients with tuberculosis (TB) of the bladder were compared with the histologic findings. TB was cytologically recognized in 11 patients because of the presence of epithelioid and/or Langhans' giant cells. The morphologic deviations of the urothelial cells and the urothelium were classified according to the criteria of Koss. The type I atypical urothelial cells found in ten patients were correlated to the urothelial hyperplasia found at histology; the follow-up data documented the benign reversible nature of the urothelial hyperplasia as the focal expression of the reactive potential of urothelium to various forms of inflammatory processes. The presence of type II atypical urothelial cells reflected moderate and severe atypia of the urothelium at biopsy. In order to assess the reactive, reversible or precancerous nature of these forms of atypia associated with TB, an accurate follow-up is necessary. Since TB of the bladder may cause the presence of atypical cells in the urine, this lesion is of special interest in the differential diagnosis between inflammatory processes and carcinoma.

Abstract
Six of the 23 patients with bladder carcinoma who underwent percutaneous pelvic node aspiration biopsy cytology for staging purposes showed positive findings from nodal chains. Pelvic lymphadenectomy revealed no false-positive or false-negative cytologic results. The fine needle aspiration of opacified pelvic nodes under fluoroscopic control is of great diagnostic value, with a high accuracy in detecting nodal extension of bladder carcinoma and providing a rational basis for proper therapy. Positive aspiration results may be accepted as a basis for therapeutic decisions. Since the metastatic involvement of multiple nodes makes any therapeutic treatment as well as cystectomy completely useless, positive aspirations from more than two nodes may spare patients an unnecessary radical surgery.

Abstract
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.
