The overall accuracy rate of EUS in the assessment of the depth of tumor infiltration was 78%.

[Kidney cancer and angiomyolipoma in lymphangiomyomatosis].

Lymphangiomyomatosis is an extremely rare benign disease characterized by extensive proliferation of smooth muscle cells within lymphatic vessels and lymph nodes. While 10-15% of all patients show concomitant renal angiomyolipomas, no association so far has been reported with renal cell carcinoma. We present a case with coincident lymphangiomyomatosis, renal cell carcinoma and renal angiomyolipoma.

We report on the case of a malignant non-Hodgkin lymphoma with primary location in the urinary bladder of an 83-year-old woman. Diagnosis was established by transurethral resection of the tumor and histological examination. No clinical signs (e.

Successful surgical treatment of liver and kidney metastases 25 years after a primary lacrimal gland tumor.

Among primary lacrimal gland tumors the adenoid-cystic carcinoma is the most common malignant epithelial lesion. We present a unique case of hepatic and renal metastases surgically treated 25 years after excision of a primary adenoid-cystic carcinoma of the lacrimal gland and after resection of intracranial and pulmonary metastases. The clinical and pathological features of this malignant tumor are discussed.

Postoperative pulmonary complications in patients with esophageal cancer.

There are recent reports on postoperative pulmonary complications in patients with esophageal cancer who were treated preoperatively with chemotherapy and irradiation. The Hamburg Esophageal Study Group is currently undertaking a prospective randomized study to evaluate the efficacy of preoperative treatment. Postoperative pulmonary complications and mortality in these patients with either a combined preoperative treatment (group 1, n = 11) or chemotherapy alone (group 2, n = 9) are evaluated in the present paper.

Endosonography for preoperative locoregional staging of esophageal and gastric cancer.

To assess the accuracy and limitations of endoscopic ultrasonography (EUS) in the preoperative staging of esophageal and gastric carcinoma, we performed a prospective controlled study over a five year period. Data from 63 patients with esophageal cancer and 147 patients with gastric cancer who underwent surgery were available for comparison of the endosonographic TNM classification to the histophathological findings of the resected specimens. The overall accuracy of EUS in the assessment of tumor infiltration depth was 85.

Enlarged lymph nodes: malignant or not?

Prospective controlled data of lymph node evaluation by endoscopic ultrasound in esophageal, gastric and pancreatic cancer is presented. Lymph node pattern, changes of boundaries and echogenicity were considered. Preoperative findings of endoscopic ultrasound were classified according to TNM staging.

Prognostic factors for adenoid cystic carcinoma of the head and neck: a retrospective evaluation of 96 cases.

Cases of adenoid cystic carcinomas of the salivary (n = 90) and lacrimal glands (n = 6) from the years 1965-1980 were evaluated retrospectively with regard to clinical, epidemiologic and histomorphologic parameters, and in 52 cases, nuclear DNA content was assessed using a single cell scanning cytophotometry procedure in order to determine prognostic factors. Clinical courses were poor with a high incidence of recurrences, hematogenous metastases and deaths from tumor. Histology was related to prognosis, glandular tumors showing a better prognosis than solid ones.

Acinic cell carcinoma of the salivary glands: the prognostic relevance of DNA cytophotometry in a retrospective study of long duration (1965-1987).

Acinic cell carcinomas of the Salivary Gland Registry, Institute of Pathology, University of Hamburg, West Germany, from 1965 to 1980 (n = 55) were evaluated retrospectively with respect to histologic, cytophotometric, and clinical data. The majority of the tumors (92.8%) were located in the parotid gland.

Variations in Feulgen stainability of epithelial parenchymal cells extracted from paraffin-embedded salivary gland specimens.

The variations of Feulgen stainability of cells extracted from paraffin-embedded archival specimens for DNA assessment by means of image cytometry (ICM) were investigated in normal salivary gland parenchyma. The Feulgen stainability of the deparaffinized, rehydrated, and disaggregated preparations was found to exhibit variations of up to 300%, expressed by the mean of integrated optical density (IOD), when a routine procedure was applied to a first series of Cytospin preparations of disaggregated specimens. When measured in nondisaggregated tissue sections, only negligible variations were observed.

Methodologic aspects of DNA assessment by means of image cytometry in tumors of the salivary glands. A comparison between the results obtained using sections and cytospin preparations from the same paraffin-embedded specimens.

The image cytometric nuclear DNA assessments on paraffin-embedded tissue sections and on Cytospin preparations of disaggregated specimens from the same cases were compared in 98 salivary gland tumors, including 21 acinic cell carcinomas, 29 mucoepidermoid carcinomas, 21 adenocarcinomas and 27 adenoid cystic carcinomas. The histogram type (diploid, tetraploid or aneuploid) and the number of cells with DNA values greater than 2.5c (expressed in relative units) were considered as variables in the correlation.

[Contribution of endosonography to preoperative staging in esophageal and stomach cancer].

A total number of 113 patients with gastroesophageal cancer (47 esophageal cancer, 66 gastric cancer) were examined by endoscopic ultrasonography (EUS). The depth of tumor infiltration in the wall, involvement of lymph nodes and spread to adjacent organs were the features particularly stressed on. 61 patients (46 with gastric cancer, 15 with esophageal cancer) underwent radical resection thus enabling a comparative study with the histological findings.

Rhabdomyoma of the larynx recurring after 12 years: immunocytochemistry and differential diagnosis.

Rhabdomyoma is a rare tumor of skeletal muscle origin which can occur in different localizations. The head and neck region is a site of predilection for the adult type. Its absolutely benign behavior makes correct diagnosis crucial.

The relationship between nuclear DNA content in salivary gland tumors and prognosis. Comparison of mucoepidermoid tumors and acinic cell tumors.

Differences in prognosis between salivary gland mucoepidermoid tumors and acinic cell tumors were compared by means of conventional histopathological grading and nuclear DNA content which was assessed cytochemically by a scanning cytophotometric procedure. The mucoepidermoid tumors were found to show a stronger correlation between histopathological grading and prognosis than did the acinic cell tumors. By using DNA quantification, valuable additional information could be obtained for predicting the behavior of the mucoepidermoid tumors, whereas there was no correlation between DNA content and prognosis for the acinic cell tumors.

Prognosis of salivary adenocarcinomas. A retrospective study of 52 cases with special regard to cytochemically assessed nuclear DNA content.

52 salivary adenocarcinomas of the years 1965-1980 from the files of the Salivary Gland Registry, Institute of Pathology, University of Hamburg, were evaluated retrospectively with regard to clinical follow up and cytochemically assessed nuclear DNA content. The age distribution showed a peak from the 6th to 8th decade (range 3 to 87 years). The m:f ratio was 1:1.
