Pleural mesothelioma and membranous nephropathy.

Underlying malignancy has been thought to be responsible for 5-10% of the cases of membranous nephropathy in adults, with the risk being highest in patients over the age of 60 years. Solid tumors such as carcinomas of lung or colon, are most often involved. It is presumed that tumor antigens are deposited in the glomeruli; this is followed by antibody deposition and complement activation, leading to epithelial cell and basement membrane injury and proteinuria due to the associated increase in glomerular permeability. We describe a patient with a resistant nephrotic syndrome and massive proteinuria due to membranous nephropathy associated with pleural mesothelioma.

Significance of proliferative epithelial changes in breast fine-needle aspiration.

The authors analyzed 6439 fine-needle aspirations (FNA). The total number of FNA performed per year at the authors' institution was found to be increasing. The authors analyzed the numbers of carcinomas and proliferative breast alterations separately. A statistically significant increase was recorded in the group of aspirate specimens that had epithelial proliferation; the increase was greater than that seen in aspirate specimens with normal epithelium (P less than 0.001). Biopsy was recommended in 151 of 6439 (2.3%) FNA and performed for 67 of the 151 (1.0%) recommendations. Cytologic findings were compared with pathohistologic findings. A histologic carcinoma was found in 14 of 67 (20.8%) patients who had biopsy performed. The authors concluded that clinicians should give particular attention to atypia in cytologic aspirate specimens.

Relationship between tissue and serum concentrations of carcinoembryonic antigen (CEA) in gastric and colonic carcinomas.

A relationship between tissue and serum concentrations of carcinoembryonic antigen (CEA) as determined by monoclonal enzymo-immunoassay (EIA) was studied in 47 patients with gastric carcinoma and 46 patients with colorectal carcinoma. The values were then compared to those obtained in a control group of 64 healthy subjects. On the basis of results, an increase in tissue CEA is not paralleled by a simultaneous increase in serum CEA. Serum CEA depends on tumor mass and points to the process extension. There is no specific tissue CEA threshold above which the serum CEA concentration should unavoidably increase. A relationship between tissue and serum CEA concentrations according to the degree of differentiation, studied in colorectal carcinomas, revealed significantly lower values of tissue CEA concentration in poorly differentiated carcinomas, whereas serum CEA concentrations did not show any such difference. The present study has suggested that, having identified both tissue and serum CEA concentrations in colorectal carcinoma, the tumor, its size and differentiation could be readily and quite closely defined at the time of measurements.

Salivary duct carcinoma metastasizing to the small bowel.

We report a case of salivary duct carcinoma in a 47-year-old woman. The patient presented with symptoms simulating acute appendicitis. Surgery revealed metastatic tumor in the wall of the small bowel. Two months later, a tumor of the right parotid gland was resected, and histologic analysis revealed a salivary duct carcinoma. To our knowledge, this is the first case of salivary duct carcinoma metastasizing to the small bowel with manifestations of metastatic disease as the prominent symptom.

Expression of carcinoembryonic antigen in ulcerative colitis, tubular adenomas and hyperplastic polyps: correlations with the degree of dysplasia.

Sections of tubular adenomas (n = 40), ulcertive colitis (n = 97) and hyperplastic polyps (n = 31) were examined by immunoperoxidase staining to carcinoembryonic antigen (CEA) in order to assess its potential diagnostic value in predicting malignant potential of these lesions. We compared the degree of epithelial abnormality in these mucosal specimens with the extent of immunoperoxidase staining for CEA. We found that CEA staining correlated with the degree of epithelial alteration in tubular adenoma and ulcerative colitis groups. Scattered weakly positive staining was found in eight of 31 hyperplastic polyps. High tissue expression of CEA, when combined with histologic dysplasia, may prove to be an additional factor in the evaluation of malignant potential in ulcerative colitis specimens and adenomas.
