Breast cancer is the most frequent feminine cancer in France and its incidence increases steadily. The time of access to medical care is an indicator of the quality of the treatments recommended by the Plan Cancer 2009-2013, as it influences the diagnosis and reduces psychological morbidity during the pre-diagnosis phase. The one-day diagnosis is a recently initiated concept, which offers to get the results of the biopsy on the day it is performed and facilitates the setting-up of therapeutic care with the surgeon met during the one-day medical consultations. The aim of this study is to evaluate the satisfaction of patients who benefited from a one-day breast lesion diagnosis, as well as confirm the decrease of time of access to medical treatment.This is an observational, non-interventional and single-centre study based on 27 patients who benefited from one-day breast lesions diagnosis over two years. The patients were only included who had a classified lesion ACR 4 or 5 and visible in the ultrasound. We analyzed the histological concordance between the biopsy and the definitive histology, the time of access to medical care, and the therapeutic treatments We analyzed the psychological impact of such an organization by sending to the patients a questionnaire including the Psychological Consequence Questionnaire (PCQ) and the Breast Cancer Anxiety Indicator (BCA) allowing to estimate the anxiety generated by the pre-diagnostic phase, the DC-Sat allowing to estimate the satisfaction of the consultation of announcement, as well as the same day diagnosis benefit.The patients were 59.8 years old in average [33-87]. The average time between the date of the mammography and the one-day diagnosis consultation (including the biopsy) was 15.0 days [0-60]. Fifty-seven percent of the patients considered this time as short. The average time between the biopsy date and the start of the treatment was 15.9 days [4-30]. The one-day diagnosis took an average of 1.6 days [1-5]. The results of the PCQ showed an important emotional impact during the diagnosis phase, and the average BCA score reached an average of 3.9 on a scale of 5. However, the patients were very satisfied with the diagnosis consultation with an average of 8.7 on a scale of 10, and 95% think the one-day diagnosis is beneficial to the patients.This study shows that the one-day breast-damage diagnosis enables to improve the time of access to care, and meets the current recommendations. Even though faster access to treatment does not reduce the psychological morbidity of awaiting diagnosis, the patients express their satisfaction and find the rapidity of the pre-diagnosis phase beneficial.In view of this study, the one-day breast-damage diagnosis appears to be a quality feature in the process of access to care and treatment of the patients.

The authors report a case of laparoscopy post mortem for unexplained inpatient death. It is minimally invasive, easy to perform, accurate, and not disfiguring. As well, it is easy to accept among mourning families. It should be considered when consent for conventional autopsy is lacking.

The aim of this retrospective study is to evaluate the impact of laparoscopic appendicectomy on the incidence of histologically normal appendices. Between 1987 and 1997, 1220 consecutives patients--with an average age of 23.5 years (17-73) and including 841 women (69%)--underwent appendicectomy due to the presence of at least one of the following 3 criteria: right iliac fossa guarding, fever greater than 38 degrees C and hyperleucocytosis greater than 10,000. Patients were divided into two group.: First group with 930 patients were operated by laparotomy and the other group of 355 patients underwent laparoscopic exploration with appendicectomy when macroscopic abnormalities were observed (290 cases). In all cases, the appendices were examined under blind conditions and classified as normal or pathological, and were subsequently classified according to the nature and the severity of the lesions. In group I (laparotomy), the incidence of histologically normal appendices was 25.1%. In group II (laparoscopic), this incidence was only 8.2%. The difference was significant (p = 0.015). In 65 cases (18.3%), a macroscopically normal appendix was left in place: in 55 cases the symptoms were due to another identified cause, however, in 10 cases no cause was found. This study suggests that laparoscopy significantly reduces the number of histologically normal appendices because an other cause is identified more easily provided macroscopically normal appendices are not removed with a small proportion (5-10%) cases of early appendicitis with only mucosal involvement. In the absence of other causes for the symptoms, a three-day course of antibiotics can be tried in order to treat possible mucosal lesions. This approach reduces costs without having any adverse consequences on outcome.

Infiltrating leukocyte population appears at the time of implantation in the endometrium of human and other mammals with hemochorial placentation. This leukocyte population is mainly composed of macrophages and typical granular lymphocytes CD56+ CD16-. 63 endometrial samples were studied using immunocytochemistry, before IVF and embryo transfer. We evaluated the sensibility for the assessment of immunological relevant infiltrating cells, of classical histopathologic examination compared with quantitation of leukocyte-common-antigen antibody immunostaining. 21 samples were thoroughly studied during proliferative phase.The sensibility of classical histologic analysis for the semi-quantitative assessment of leukocyte population, even when performed by an experienced histopathologist, is only 62%. When leukocyte population during proliferative phase is dense, it is mainly composed of macrophages and CD56+ CD16- lymphocytes.Immunological reaction already reported around the time of implantation may occur at other period of the menstrual cycle. Close mechanisms of the control and functions of this characteristic reaction remain to clarify.

Giant-cell hepatitis is rare in adults and its significance has not been clarified. We report the clinical and histological characteristics and outcome in a group of adult patients with giant-cell hepatitis.Seventeen patients with giant-cell hepatitis, hospitalized in our unit between 1976 and 1992, were studied retrospectively. Giant-cell hepatitis was defined as at least two hepatocytes with four or more nuclei per cell on liver biopsy. Clinical and biochemical parameters, liver histology, and the serological profile of HAV, HBV, HCV, HIV, HSV, EBV, CMV, and paramyxovirus were evaluated. Paramyxovirus immunochemistry was performed in 6 liver biopsies.There were 11 females and 6 males, an average of 48 years old (range: 29-80). Four patients had a well-defined etiology: acute hepatitis B infection with a favorable outcome in 2 cases, clometacine induced-hepatitis resulting in death from liver failure in one case, and chronic hepatitis B and C in one patient with AIDS. Among the 13 patients in which the etiology could not be determined, histologically defined acute hepatitis was observed in 8 and chronic hepatitis in 5. Nine patients were treated with immunosuppressive drugs. One patient was lost to follow-up. Eight patients responded to treatment, but 5 patients progressed to cirrhosis between 5 months and 7 years. Two of the 4 patients with unexplained liver disease who did not receive any treatment died of liver failure.In patient with acute or chronic hepatitis without an identified cause (with or without autoimmune abnormalities), the presence of giant-cell hepatitis seems to have a similar evolution as active autoimmune hepatitis. The poor prognosis of these patients suggests that early immunosuppressive treatment is justified.

Long term treatment by fibrates could induce chronic hepatitis associated with auto-antibodies. The aim of this study was to assess the features of this hepatitis.Baseline clinical and biological features, and liver biopsy in 5 patients with fibrate-induced chronic hepatitis were studied, as well as their outcome.At enrollment, patients (4 men, mean age 65 years) had highly (n = 3) or mildly (n = 2) increased serum aminotransferase activity, hypergammaglobulinemia and high titers of anti-nuclear antibodies (with homogenous fluorescence in 3 cases). Liver biopsies demonstrated a lympho-plasmocytic infiltrate in all cases. Hepatocellular necrosis was multilobular in 2 cases, and mild to moderate, located in lobular and periportal areas in 3 cases. Cirrhosis was found at presentation in 3 cases and developed within a few months in the 2 other patients. After discontinuation of fibrates, aminotransferase activity normalized within 6 weeks either spontaneously (n = 3) or under immunosuppressive treatment (n = 2). Immunosuppression was rapidly withdrawn in 2 patients (18 months) without relapse, while one patient was treated for 4 years because of relapse after early withdrawal. A second liver biopsy performed 6 months after discontinuation of fibrates in an untreated-patient showed no inflammation or necrosis.These observations suggest that fibrates could trigger chronic liver disease resembling type I auto-immune chronic hepatitis, which resolves after drug withdrawal.

Patients with acquired immunodeficiency syndrome are often susceptible to atypical dissemination of visceral leishmaniasis. Digestive localizations seem to be relatively frequent. Colonic localizations reported in the literature are endoscopically normal or show superficial mucosal lesions. We describe an original case of leishmaniasis associated with a colonic pseudotumoral stenosis with perforated ulcer penetrating in the mesocolon. Striking inflammation of mesenteric blood vessels, even far from the ulcer, suggested an ischemic mechanism for the colonic stenosis. These findings raise the hypothesis that vasculitis is secondary to mucosal parasitic infection.

Nodular regenerative hyperplasia of the liver is characterized by diffuse nodularity of the hepatic parenchyma without fibrotic septa. It may be related to venous or arterial obstruction in the portal tract. We report a case of primary antiphospholipid syndrome associated with nodular regenerative hyperplasia in a 45-year old woman. The patient had an ischemic stroke, associated with an acute arterial ischemia of the left leg. She had high titers of serum anticardiolipin antibodies. Nodular regenerative hyperplasia of the liver was histologically confirmed and was associated with anicteric cholestasis. This case provides additional evidence that a thrombotic mechanism may play a role in the pathogenesis of nodular regenerative hyperplasia of the liver.

We report an Hepatitis B Virus reactivation, in a patient with an end-stage Human Immunodeficiency Virus infection who developed a rapidly progressive liver failure in four months. The main histological features include ballooning of hepatocytes and ground glass transformation, without significant inflammation. Immunohistochemical staining showed a high expression of viral antigens. This case can be related to "Fibrosing Cholestatic Hepatitis", first described after liver transplantation for cirrhosis B. The mechanism of hepatocellular damage is likely to be a direct cytotoxicity of hepatitis B virus.

The simultaneous disclosure of a lymphoblastic B cell lymphoma and sarcoidosis is reported herein. The initially undiagnosed sarcoidosis leads to discuss the differential diagnosis of a sarcoid-like reaction associated to the lymphoma. The association of sarcoidosis and malignant lymphoproliferative disease is not fortuitous; nevertheless the simultaneity of the two diagnoses, the lymphoblastic type of the lymphoma and the colocalization of granulomatous and lymphomatous lesions in lung and liver are unusual features.

The authors report a case of adenoid cystic (cylindromatous) carcinoma of the endocervical canal associated with an intraepithelial squamous cell carcinoma of the cervical os in a 60-year-old woman suffering from metrorrhagia. Immunohistochemical study demonstrated labeling of cylindromatous cells with anti-actin, anti-vimentin and anti-keratin antibodies. Ultrastructural study provided significant findings to confirm that the hyaline material surrounded by tumor cells was derived from the remnants of the lamina densa of the basement membrane of tumor lobules. These morphological data are similar to those observed in adenoid cystic carcinomas (cylindromas) of salivary glands. They support the hypothesis that adenoid cystic carcinoma of the cervix may develop from the multipotent reserve cells.

Whipple's disease and pulmonary and lymph node tuberculosis have been diagnosed in a 70 year-old man hospitalized for weight loss and fever. The tuberculous or Whipple's disease-related nature of associated non-necrotizing epithelioid hepatic granulomas could not be determined. The existence of cellular immune defects in Whipple's disease could explain the association with tuberculosis, which has not been previously reported in the literature.

Hyalinizing trabecular adenoma of the thyroid gland is an uncommon neoplasm that was recently described by Carney et al. (1987). It is important to recognize this tumor, considered benign, as it may mimic papillary carcinoma, medullary carcinoma or paraganglioma. We present two cases with histological and immunohistochemical criteria and discuss the diagnostic problems. Grossly, this small tumor is yellow tan and well circumscribed. The epithelial cells, polygonal or elongated and sharply outlined, have an eosinophilic or clear cytoplasm. The nuclei are oval or elongated, with often non-visible nucleoli. Grooved nuclei are quite frequent. Mitotic figures are very uncommon. The cells are arranged in clusters or trabeculae or pseudofollicles containing colloid material. Characteristically the cells, arranged shoulder to shoulder, can show a palisade pattern. The fibrovascular stroma appears hyaline, pseudoamyloid (Congo red staining is negative). The tumor cells show intense staining for thyroglobulin and no staining for thyrocalcitonin. Immunoreactivity for cytokeratin, vimentin, protein S100, NSE is positive but staining is negative for EMA and desmin. In one case, the tumor cells show little positivity for chromogranin A. The variable patterns of this tumor can lead to diagnostic problems. We can exclude the diagnosis of papillary carcinoma as this tumor lacks any true papillary architecture. We reject the diagnosis of medullary carcinoma because of its thyroglobulin and calcitonin immunoreactivity. Paraganglioma never shows immunoreactivity for thyroglobulin. Very often the surrounding thyroid tissue shows focal thyroiditis. The association of the tumor with Hashimoto's thyroiditis can be explained by an autoimmune process.

A case of primary cardiac lymphoma (PCL) is reported in a patient presenting with chest pains. This PCL was treated with surgery. The histology showed a large cell lymphoma. The immunohistochemical study demonstrated the B cell origin of this PCL.

A case of massive amyloidosis without detectable monoclonal Ig component either in serum or in urines on classical electrophoresis and without obvious plasma cell proliferation is reported. Immunohistochemical study of renal and bone marrow biopsies showed that amyloid deposits were specifically stained with the anti-lambda antiserum and that 92% of the plasma cells were also lambda positive. Immunofixation following electrophoretic analysis of serum and urinary proteins exhibited a monoclonal lambda light chain at an advanced stage of the disease. Simple but not routinely used techniques are therefore of great interest to characterize apparently idiopathic amyloidosis which could have therapeutic implications.

The three cases reported here illustrate the diagnostic, therapeutic and prognostic problems raised by these tumours. These are rare lesions with little suggestive symptoms, which explains why they are exceptionally diagnosed before surgery. Mucosal hyperplasias and cystadenomas are benign formations with a 90-100% survival rate 5 years after appendicectomy, even when non-cellular mucoid effusion is present. Cystadenocarcinomas are malignant tumours with mucoid secretion containing epithelial cells; they have a tendency to recur despite repeated evacuations, and their 5-year survival rate is approximately 25%; death results from intestinal obstruction or compression of intra-abdominal viscera by the mucoid substance.

This case report describes a patient with IgG lambda myeloma and vascular amyloidosis. Remarkable is the presence of mesangial granular deposits revealed by electron microscopy and positive with anti-IgG and anti-kappa anti-serum in an immunofluorescence study. Granular dense deposits were also found at the inner side of the basement membrane of the skin and were positive with anti-kappa anti-serum in immunofluorescence study. Because no L kappa q light chain proliferation could be demonstrated, the nature and significance of these kappa deposits are not clear.

To block the renin-angiotensin system by antibodies directed against renin or angiotensins is an old and recent goal. This goal can be attained by passive transfer of antibodies or by active immunization against the different molecules of the system. Only passive transfer of polyclonal antibodies directed against the native substrate (angiotensinogen) has been performed in rats. This acute blockade of angiotensinogen substrate availability decrease blood pressure about 30 mmHg in salt depleted rats. Passive transfer of anti-converting enzyme immunoglobulins has been already performed in rabbit and rat. It induced an immunoallergic reaction in the pulmonary capillary bed. Immunization against angiotensin II has been a powerful tool in the exploration of the role of the renin angiotensin system in hypertension. Passive and active immunization have been performed in different species: rabbit, rat. The majority of the results concerning the decrease in blood pressure was negative. However, some works reported positive results which could be related to the high affinity of antibodies for angiotensins. Passive and active immunizations against renin were also performed in different species: dog, pig, rat, rabbit, primates. The majority of the results concerning the decrease of blood pressure were positive, if species specificity of renin was taken into account. Recently passive transfer of polyclonal and monoclonal antibodies, directed against human renin have been performed in normotensive and hypertensive primates, demonstrating an acute fall in blood pressure comparable to that observed with converting enzyme inhibitors. Active immunization against human renin has also been performed in primates; and the chronic blockade of the renin-substrate reaction obtained in this way was associated with a significant decrease in blood pressure, aldosterone secretion and a disappearance of plasma renin activity. Unfortunately, such an active immunization was associated with an organ specific autoimmune disease within the kidney. In conclusion, passive and active immunization against the different proteins and peptides of the system offers specific models of blockade which can be compared with synthetic inhibitors of renin, converting enzyme and angiotensins. Therapeutic application of this immunological approach necessitates the verification of the total absence of autoimmune disease.

465 patients with broncho-pulmonary malignant tumors have been autopsied. Small cell carcinoma was diagnosed in 22.5 per cent of these patients. The histo-cytological variants of these tumors (lymphocytoid, polygonal, fusiform and polymorphic) had the same general characteristics (age, sex, survival) and a similar clinical course. Grossly and histologically, the bronchial tumor, always located in proximal bronchial tree, largely involved the mediastinum. Metastases were peculiarly frequent to the liver (69%), to bone (64.2%) and to the central nervous system (36.2%). Three Schwartz-Bartter syndromes and two Denny Brown sensitive neuropathies were noted in this statistical study.
