Intestinal localization of rhabdomyosarcoma is exceptional, this case is the first to be published in the world literature. A 35-year-old patient with abdominal pain, fever, was found to have an infiltrative white-grey tumour, involving 20 cm the jejunoileal wall and also the surrounding mesenterium up to the origin of upper mesenterical vessels and lymph nodes. Histologic examination showed an alveolar type of rhabdomyosarcoma intricated with solid undifferentiated tumoral cells. The presence of multinucleated giant cells and the positivity of protein S 100 reaction was important for differential diagnosis, given the alveolar soft part sarcoma, malignant mesothelioma, malignant melanoma or papillary carcinoma.

Serous surface carcinoma (SSC) of the peritoneum is defined as a primary tumor histologically indistinguishable from serous carcinoma of the ovary, diffusely involving the peritoneal surface but sparing or only superficially invading the ovaries. In this study of 22 cases of SSC, it was found that the main clinical manifestations of SSC were abdominal pain and enlargement. In most cases, SSC evenly involved the entire mesothelial surface but rarely was predominant in or even limited to the pelvis. It frequently invaded the submesothelium, but deep invasion into abdominal and pelvic organs or local metastasis was rare, and distant metastasis was not seen at presentation. Microscopically, SSC was a high-grade tumor frequently showing high mitotic rate, psammomas bodies, and necrosis. The tumor was usually contiguous with hyperplastic mesothelium on either ovarian surface or other locations. Tumor cells in all cases except one showed cytoplasmic or surface neutral or acidic mucin or both. Tumor cells stained positive for keratin (100% of cases), epithelial membrane antigen (100%), Leu-M1 (45%), B72.3 (85%), vimentin (35%), and carcinoembryonic antigen (25%). Electron microscopic studies of six cases showed epithelial differentiation in each. Seven patients (32%) were alive with no clinical disease at 3 to 31 months, one patient (4%) was alive with extensive local disease at 24 months, 11 patients (50%) died almost exclusively of local recurrence at 1 to 70 months, and three patients (14%) died of operative complications. It is concluded that SSC arises from peritoneal mesothelium but has epithelial phenotype. It can be morphologically differentiated from other conditions with similar laparotomy findings, such as malignant mesothelioma, benign papillary mesothelioma, cystic mesothelioma, and benign or borderline peritoneal serous tumors. The prognosis of SSC is poor, and most patients die of uncontrollable local disease.

A 57-year-old man with malaise, ascites, and abdominal pain was found to have a peritoneum studied with numerous, small nodular tumor masses. Light microscopy revealed an anaplastic malignant tumor of uncertain differentiation. Mucin stains were negative. Electron microscopy revealed pleomorphic tumor cells with diffusely distributed cytoplasmic tonofilaments and well-developed true desmosomes. No long, thin, branching microvilli were present, yet tumor cells were strongly positive for both callus keratin (polyclonal) and monoclonal cytokeratin (AE1/3) in a diffuse cytoplasmic distribution (a pattern corresponding to the diffuse cytoplasmic tonofilaments). Tumor cells were negative for Leu-M1 and carcinoembryonic antigen. The findings were most consistent with malignant mesothelioma, and additional questioning, after tissue diagnosis, revealed a work history of asbestos exposure.

The aim of the present study was to further elucidate acute and chronic manifestations of Yersinia enterocolitica infection. During the period 1974-83, 458 hospitalized patients were diagnosed by antibody response and/or isolation of the microorganism. 64 patients had suffered from chronic conditions as rheumatic disease, inflammatory bowel disease, hepatitis, nephritis or thyroid disease for some time. Acute hepatic, renal, cardiac, pulmonary, pancreatic or neurologic involvement were observed in a substantial portion of patients; several had multiorgan disease. Acute insulin-dependent diabetes was seen in 2 patients, malignant mesothelioma in 2, and specific lymph node inflammation in 1. The patients were followed for 4-14 years (1987). 36/160 readmitted patients had abdominal pain and 26 had diarrhea; chronic colitis was demonstrated in 4. Some patients developed rheumatic conditions; others developed chronic disease of liver, kidneys, heart, pancreas, thyroid or nervous system. Chronic liver disease, in 22 patients, was correlated with positive tests for antinuclear antibody and rheumatoid factor; and might influence development of malignant disease, and mortality. A variety of acute and chronic clinical pictures may be associated with Y. enterocolitica infection, and further clinical research is required in this field.

A cohort of 820 asbestos workers with a short duration of exposure to amosite between 1941 and 1945 was followed. These men were alive five years after starting work and were observed until 1988. Seventeen cases of malignant mesothelioma (eight pleural, nine peritoneal) were found. The mean age at the onset of exposure was 33 years for men with pleural mesothelioma and 30 years for those with peritoneal mesothelioma. Chest pain was the main symptom in pleural mesothelioma and abdominal pain in peritoneal mesothelioma. Open lung biopsy was the most useful diagnostic approach for pleural mesothelioma, whereas for peritoneal mesothelioma it was exploratory laparotomy. Pleural patients died of pulmonary insufficiency, and peritoneal patients of wasting and inanition. In both groups the death certificate diagnosis was less accurate than the clinical diagnosis at death. The mean survival was 12.5 months from first symptom to death for the pleural group and 5.4 months for the peritoneal group.

Malignant mesothelioma has been rare in the general population. In recent decades its incidence has risen dramatically, parallel to the increasing use of asbestos in industry since 1930. Altogether 17,800 asbestos insulation workers, members of the International Association of Heat and Frost Insulators and Asbestos Workers (AFL-CIO-CLC) in the United States and Canada, were enrolled for prospective study on 1 January 1967 and followed up to the present. Every death that occurs is investigated by our laboratory. One hundred and seventy five deaths from mesothelioma occurred among the 2221 men who died in 1967-76 and 181 more such deaths in the next eight years. Altogether, 356 workers had died of malignant mesothelioma (pleural or peritoneal) by 1984. Diagnosis of mesothelioma was accepted only after all available clinical, radiological, and pathological material was reviewed by our laboratory and histopathological confirmation by the pathology unit made in each case. One hundred and thirty four workers died of pleural and 222 of peritoneal mesothelioma. Age at onset of exposure, age at onset of the disease, and age at death were similar in both groups of patients. Significant difference was noted only in the time elapsed from onset of exposure to the development of first symptoms, which was longer in the group with peritoneal mesothelioma. Shortness of breath, either new or recently increased, and chest pain were the most frequent presenting symptoms in the group with pleural mesothelioma; abdominal pain and distension were frequent in the patients with peritoneal mesothelioma. Pleural effusion or ascites were found in most patients. The most effective approach to the diagnosis of malignant pleural mesothelioma in these cases was by open lung biopsy; exploratory laparotomy was best for diagnosing peritoneal mesothelioma. Patients with pleural mesothelioma died principally from pulmonary insufficiency whereas those with peritoneal mesothelioma succumbed after a period of pronounced wasting.

A Phase I trial of intraperitoneally administered 5-FU and citrovorum factor was performed in eight patients with a variety of malignancies. Both drugs were given according to a single weekly dose schedule in a volume estimated to be 2000 cc, including residual ascites. Citrovorum factor 50 mg was given first, immediately followed by 5-FU 1000-3400 mg, according to a dose-escalating schedule. Myelosuppression proved to be the dose-limiting toxicity, though mucositis, diarrhea, nausea, and abdominal pain were also produced. Six patients failed to respond to therapy. One patient with malignant mesothelioma showed a significant decrease in the production of malignant ascites and a transient conversion of peritoneal fluid cytologies from positive to negative, while a second patient with pancreatic cancer showed conversion of peritoneal fluid cytologies from positive to negative and demonstrated an objective partial response of an hepatic metastasis. Dosage adjustment according to body surface area would seem indicated by the toxicity data, with a 5-FU dose of 1200 mg/m2 body surface area and citrovorum factor 50 mg/m2 being recommended for Phase II trials of this combination of drugs given according to this weekly schedule.

Peritoneal serous papillary carcinoma is a rare primary tumor of the peritoneum. We report here a case diagnosed by laparoscopy, and summarize the clinicopathological features previously reported in patients with this tumor. Laparoscopy was performed in a 66-year-old woman with high-protein ascites and a three-month history of lower abdominal pain. Macroscopically, the parietal and visceral peritoneum was studded with prominent white nodules up to 5 mm in diameter. Multiple biopsies revealed a tubulopapillary serous adenocarcinoma. After exclusion of metastatic peritoneal carcinomatosis (especially ovarian cancer) and malignant mesothelioma, the diagnosis of peritoneal serous papillary carcinoma was established. The patient was placed on chemotherapy (first-line: 5-fluorouracil, adriamycin, and mitomycin C; second-line: paclitaxel). She died 22 months after diagnosis. The present case is also remarkable for the coexistence of granulomatous peritonitis overshadowing the malignant nature of the process. This case report emphasizes the importance of laparoscopy with multiple biopsies in the workup of undetermined exudative ascites.

Mesenteric panniculitis (MP) is characterized by an abdominal inflammatory reaction and mesenteric fat necrosis. Clinically, MP manifests as recurrent abdominal pain, pyrexia, and space-occupying peritoneal masses. We report a patient with MP, severe enough to require immunosuppressant treatment, who developed a recurrent pleural effusion. Malignant mesothelioma was identified in the pleural space 3 yr after initial pleural investigation. This case is the second report of pleural effusion associated with MP. It is the first report in which thoracic mesothelioma and MP occurred together. MP has been associated with other malignancies.

Australia is currently experiencing an epidemic of malignant mesothelioma. The clinical aspects of malignant mesothelioma were investigated in 295 Australian patients as part of a national study of the disease. Most patients were male (91%), with the mean age at diagnosis being 64 years. The predominant cell type was epithelial (38%) and the majority of primary tumours arose from the pleura (94%). Mean survival was poor (17.6 months from first symptom; 11.8 months from diagnosis). Patients with a pleural primary tumour were more likely to present with dyspnoea, chest pain and cough; to have a pleural effusion diagnosed radiologically; and to have metastatic spread. Patients with a peritoneal primary tumour were more likely to present with weight loss, loss of appetite, abdominal pain and ascites; to have radiologic evidence of asbestos exposure; and to have spread along a needle track created during a diagnostic tap. A minority of patients had past thoracic conditions, or radiologic findings, specifically related to previous asbestos exposure. About one fifth of patients had no known asbestos exposure. Forty-one per cent of subjects received some form of chemotherapy, radiotherapy and/or surgery, but no formal disease staging had been documented for any patient. Proper controlled trials of secondary and tertiary treatments in malignant mesothelioma are now needed.
