Peritoneal malignant mesothelioma versus serous papillary adenocarcinoma. A histochemical and immunohistochemical comparison.

In order to evaluate adjunctive histologic methods for separating mesothelioma (MM) and serous adenocarcinoma (SC), we studied 28 and 46 respective cases histochemically and immunohistochemically. Ten serous adenocarcinomas arose primarily in extraovarian sites within the abdomen. Diagnoses in each case were established retrospectively by a combination of electron microscopy and clinicopathologic correlation. A panel of antibodies to cytokeratin (CK), epithelial membrane antigen (EMA), B72.3, placental alkaline phosphatase (PLAP), S-100 protein, carcinoembryonic antigen (CEA), Leu M1, CA-125, and amylase (AM) was applied to paraffin sections of each case. Serous carcinoma was reactive for neutral mucins whereas mesothelioma was not; however, only 50% of adenocarcinoma cases stained in this manner. Peritoneal mesothelioma showed reactivity for CK (28 of 28 cases), EMA (24 of 28 cases), AM (five of 28 cases), CA-125 (four of 28 cases), and S-100 protein (three of 28 cases), but lacked B72.3, PLAP, and CEA. Three mesotheliomas expressed Leu M1, but in an extremely focal distribution. Serous carcinoma reacted for CK (46 of 46 cases), EMA (46 of 46 cases), CA-125 (42 of 46 cases), S-100 protein (40 of 46 cases), Leu M1 (34 of 46 cases; with diffuse staining), B72.3 (33 of 46 cases), PLAP (29 of 46 cases), AM (15 of 46 cases), and CEA (six of 46 cases). Two profiles (S-100 + B72.3; S-100 + PLAP) were seen in 41 of 46 serous adenocarcinoma cases but were absent in all mesotheliomas. Hence, these combinations of determinants are effective in separating such neoplasms diagnostically. Moreover, diffuse reactivity for Leu M1, B72.3, PLAP, or CEA in papillary peritoneal neoplasms appears to exclude the possibility of mesothelioma; however, focal Leu M1 reactivity may indeed be seen in mesothelioma. Although CA-125 is a sensitive marker for serous carcinoma, it is not effective in distinguishing it from mesothelioma.

Serous papillary carcinomas arising from the peritoneum and ovaries. A clinicopathologic and immunohistochemical comparison.

Primary papillary serous carcinoma arising from the peritoneal surface (serous surface papillary carcinoma; SSPC) is a distinctive neoplasm with a histomorphologic resemblance to serous ovarian papillary carcinoma (SOPC). To determine if these tumors are similar antigenically, we studied 13 examples of SSPC and 31 of SOPC immunohistochemically. Antibodies to several determinants known to occur in the Müllerian epithelium were employed. Both neoplasms were uniformly positive for cytokeratin and epithelial membrane antigen (EMA); in addition, SSPC and SOPC were similar in quantitative and qualitative reactivity for B72.3 antigen, carcinoembryonic antigen, Leu M1, CA-125 antigen, LN1, LN2, MB2, S100 protein, placental alkaline phosphatase, and amylase. Residual nonneoplastic mesothelium failed to express any of these antigens except for cytokeratin, EMA, and CA-125. The clinical behavior of SSPC was similar to that of high-stage SOPC; all patients with adequate follow-up died of their tumors. These results suggest that SSPC and SOPC are analogous lesions, with respect to their cellular differentiation. Moreover, it would appear that both neoplasms display only a limited immunophenotypic homology to the mesothelium.

Isolated valvular amyloid.

Two cases are described of grossly evident amyloid infiltration of the cardiac valves, while only minor deposits were found in other locations. The right-sided valves were more heavily involved than the left. No pre-existing disease of the valves was found, and the lesions appeared to have no adverse effect upon the subjects. Only one other similar case was found in the literature. The only consistently associated condition among the recognized cases was advancing age. The name proposed for the condition is isolated valvular amyloid.
