A 39-year-old woman undergoing immunosuppressive therapy following kidney transplantation for systemic lupus erythematosus presented with a uterine adenomatoid tumor that diffusely infiltrated the entire myometrium and contained a serosal papillary cystic component that resembled a cystic mesothelioma. This is the first reported case of an adenomatoid tumor showing both of these features. Although adenomatoid tumors are considered benign, the patient may be at risk for recurrence of the papillary cystic component (which is known to recur in 50% of cases) if this tumor reflects an inability to limit neoplastic processes.

A case of congenital atrioventricular block in a newborn whose mother presented with systemic lupus erythematosus (SLE) is reported. Despite intensive care the child died a few hours after birth. Serial sections of the heart could be examined. Histology provided information on the appearance and distribution of the lesions. In particular, the sinus node was small for the child's age, and its supplying artery was found to have a hyperplastic media with adventitial sclerosis; the interatrial and interventricular septa showed subendocardial fibrosis invading the adjacent myocardium. Owing to the scarcity of systematic histopathological examinations, such lesions have seldom been described. In addition, a tumour of the atrioventricular node, known as mesothelioma or hemolymphangioma, was discovered. This case is exceptional in that histopathological findings similar to those described in SLE, though rarely as numerous, were associated with a very rare tumour never hitherto described in such a young patient. The relationship between the two categories of lesions is discussed.

A prospective study of pleural fluid eosinophilia (PFE) during initial thoracocentesis in 162 patients of pleural effusion was undertaken to determine its value in establishing an etiological diagnosis. Eighteen of the 162 cases showed pleural fluid eosinophilia (PFE), twelve could not be labelled with any definitive etiology even after extensive investigations, four belonged to the para-pneumonic group and resolved with treatment. Of the 32 patients with malignancy, PFE was seen in a single case of pleural mesothelioma. None of the patients with tuberculosis, empyema, systemic lupus erythematosus or amoebiasis had PFE. These findings suggest that PFE seen at initial thoracocentesis favours a benign diagnosis, with a rare chance of malignancy. Tuberculosis is unlikely in such patients.

A case of mesothelioma of the pericardium with many features of systemic lupus erythematosus (SLE) is described. We stress that satisfaction of the American Rheumatism Association's classification criteria for SLE does not confirm the diagnosis, even though their diagnostic sensitivity and specificity has recently been improved.

The role of laparoscopy in the diagnostic evaluation of ascites of unknown origin was studied in 129 patients. Laparoscopic results were as follows: (1) Carcinomatosis peritonei in 78 (60.5%). Peritoneal biopsies in 76 of these cases revealed malignancy in 67 (adenocarcinoma 62, lymphoma 4, mesothelioma 1) and tuberculosis in 5; specimens were inadequate for diagnosis in 4. (2) Tuberculous peritonitis in 26 (20.2%). Peritoneal biopsies in 24 of these cases revealed tuberculosis in 22 and non-specific chronic peritonitis in 2. (3) Cirrhosis in 7 (5.4%). (4) No gross abnormality in 18 (14.0%). Of the latter, causes of ascites had already been identified in 13 (72.2%), including chronic renal failure in 7, systemic lupus erythematosus in 2, constrictive pericarditis in 2, chronic pancreatitis with chylous ascites in 1, and retroperitoneal lymph node metastasis with chylous ascites in 1. Thus, laparoscopic observation in combination with biopsy established the cause of ascites of unknown origin in 111 (86.0%) of 129 patients. Most of the 18 patients without gross laparoscopic abnormality had underlying disease identified as a cause of ascites; laparoscopy was indicated in these cases to exclude other processes that may also cause ascites.

Despite a body of evidence supporting an association between asbestos exposure and autoantibodies indicative of systemic autoimmunity, such as antinuclear antibodies (ANA), a strong epidemiological link has never been made to specific autoimmune diseases. This is in contrast with another silicate dust, crystalline silica, for which there is considerable evidence linking exposure to diseases such as systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis. Instead, the asbestos literature is heavily focused on cancer, including mesothelioma and pulmonary carcinoma. Possible contributing factors to the absence of a stronger epidemiological association between asbestos and autoimmune disease include (a) a lack of statistical power due to relatively small or diffuse exposure cohorts, (b) exposure misclassification, (c) latency of clinical disease, (d) mild or subclinical entities that remain undetected or masked by other pathologies, or (e) effects that are specific to certain fiber types, so that analyses on mixed exposures do not reach statistical significance. This review summarizes epidemiological, animal model, and in vitro data related to asbestos exposures and autoimmunity. These combined data help build toward a better understanding of the fiber-associated factors contributing to immune dysfunction that may raise the risk of autoimmunity and the possible contribution to asbestos-related pulmonary disease.

Spontaneous hemopneumothorax (SHP) is observed in 3%-7% cases of spontaneous pneumothorax where the tear of an adhesion can lead to bleeding with associated hemothorax. This condition has been reported in patients with hemophilia, sarcoidosis, congenital cystic adenomatoid malformation, systemic lupus erythematosus, etc., Here, we describe an unusual case of acute massive SHP in a 62-year-old male who underwent a percutaneous transluminal coronary angioplasty (PTCA) and presented with worsening dyspnea over the next 3 days. On evaluation, he had a massive hemopneumothorax which was considered to be secondary to the use of anticoagulants during the PTCA procedure. Pleural fluid analysis revealed frank blood and was consistent with the diagnosis of hemothorax. Surprisingly, the pleural fluid cytology revealed malignant cells. As the patient had a normal chest X-ray 3 days ago, thoracoscopic pleural biopsy was taken which confirmed the diagnosis of an epithelioid mesothelioma. Although post-PTCA or mesothelioma-associated hemothorax has been rarely reported, these two conditions have not been associated with SHP. Since the patient had no prior clinicoradiological features of mesothelioma, the procedure, and the anticoagulants probably contributed to the massive and rapid accumulation of blood. The presence of small amount of air added further confusion to the dual etiology and has not been described earlier.

While malignant mesothelioma may initially present in a variety of ways, it is uncommon to present with systemic lupus erythematosus (SLE) seropositivity and thus obscuring its diagnosis. Our case involves a 75-year-old Caucasian male with a past medical history of essential hypertension, remote prostate cancer status post prostatectomy, and lifetime nontobacco use presenting with progressive shortness of breath over one month. After a negative cardiac assessment, a postcardiac catheterization chest X-ray (CXR) revealed a right-sided moderate-to-large pleural effusion that, on further workup, was found to be exudative. Effusion studies were negative for malignancy and bacterial growth. Recurrent accumulation of fluid after a thoracentesis one week prior prompted an autoimmune work up. Positive markers included antinuclear antibodies, anti-double stranded DNA antibodies, and anti-histone antibodies, while anti-Smith antibodies were negative. Although SLE was initially suspected based on serologies, no clinical signs or symptoms were present to fulfill the diagnosis criteria. A trial of oral prednisone resulted in decreased pleural effusion size with no further recurrence. Additional studies included a CT scan of the chest that showed pleural masses confirmed with biopsy to be epithelioid mesothelioma. Given the patient's age and new diagnosis of malignant mesothelioma, we hypothesized that the presence of autoantibodies was likely false positives due to acquired autoantibodies with age, hyperactivity of the immune system from malignancy, and possible prior asbestos exposure.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease characterised by inflammation. Malignant pleural mesothelioma (MPM) is a highly invasive malignant tumor derived from pleural mesothelial cells. Here, we report a case of SLE with MPM. A 42-year woman with no exposure to asbestos presented with severe left chest pain. Initially, we diagnosed her with SLE because of the clinical manifestations and high antinuclear antibody titer. Finally, a diagnosis of MPM was made, based on pleural biopsy. Her condition was under control after one cycle of chemotherapy and oral methotrexate. However, three years later, she was admitted with dyspnea, mild orthopnea, and tachycardia, and died one month later after discontinuing treatment. MPM is rare, and MPM with SLE is even rarer. We should pay attention to pleural effusion when diagnosing SLE. If possible, a pleural biopsy should be performed to reduce misdiagnosis and missed diagnosis. Key Words: Pleural effusion, Systemic lupus erythematosus (SLE), Mesothelioma.
