    Notes: Summary Signs of glomerulopathy, especially a nephrotic syndrome can occur in cancer patients, but the exact frequency of glomerular lesions is not well known in these patients. To define this frequency in a given type of malignancy we have studied the nephrectomy kidneys in 40 patients with renal cell carcinoma. Proteinuria, which was present in 7 cases, ranged from 0.15 to 1.5 g per 24 h. Reduction of the creatinine clearance greater than 50% was observed in 5 patients. Circulating immune complexes were detected in 11 of the 15 patients studied. Carcinoembryonic antigens were noted in 2 of 9 patients investigated. Research of alpha 1 foetoprotein carried out in 12 patients was always negative. HBs antigen or Hbs antibodies were detected in 6 of 29 patients studied. Light microscopic examination of the normal uninvolved kidney tissue showed obvious glomerular lesions (mesangial hypertrophy with or without deposits, with or without cell proliferation) in 7 patients (17.5%). Amyloid deposits were never observed. Immunofluorescence study revealed mesangial deposits in 35% of patients versus 5.4% of control subjects (P 〈 0.0001). These deposits included C3 and/or IgM in 13 cases, IgA and C3 in one case. No fixation was observed, neither on tubules of normal tissue nor on carcinoma lesions. This report demonstrates that glomerular deposits are usually found in approximately one third of patients with renal cell carcinoma and that these deposits are located in the mesangial areas and not in the subepithelial space as it is often observed when glomerulonephritis is expressed by clinical symptoms.

    Notes: Abstract. Recently, the term ``serous cystadenoma'' has been adopted in the pathological community to qualify the so-called microcystic adenoma of the pancreas. This change in terminology was based on the emergence of a new type of serous cystadenoma of the pancreas, i.e., the macrocystic variant. We report one case of pathologically proven macrocystic serous cystadenoma of the pancreas for which the diagnosis of mucinous cystadenoma was suggested preoperatively. This rare but benign macrocystic variant exhibits radiological features similar to those of mucinous cystadenoma. In addition, inflammatory changes and foci of hemorrhage within the tumor may simulate mucinous cystadenocarcinoma. RID=""ID=""〈e5〉Correspondence to:〈/e5〉 P. Soyer

    Renal cell carcinoma of clear type: correlation of CT features with tumor size, architectural patterns, and pathologic staging (1997)

    Notes: Abstract. The purpose of this study was to report the CT findings of renal cell carcinoma of clear type (RCCCT) and to determine if there are characteristic morphologic features in RCCCT with respect to tumor size, architectural patterns, and pathologic stage. The CT scans of 35 patients with RCCCT were reviewed retrospectively. The CT findings (tumor size, attenuation patterns, presence of calcifications, encapsulation, margins of neoplasms, venous involvement by neoplasms) were correlated with tumor size, architectural patterns, and pathologic staging. Of the 35 neoplasms, 28 (80 %) were solid, 4 (11 %) were papillary, and 3 (9 %) were cystic. Complete encapsulation was more frequent in lower pathologic stages (40 % in stages 1 and 2 vs 0 % in stages 3 and 4; p 〈 0.05). Venous involvement was less frequent with completely encapsulated neoplasms (0 of 10, 0 %) than with incompletely or nonencapsulated neoplasms (8 of 25, 32 %; p 〈 0.05). Encapsulated RCCCT are more likely to have lower pathologic stage. Nonencapsulated neoplasms are more likely to have a higher pathologic stage.
