[A comparative clinical and pathological study on the classification and prognostic features of 57 thymomas. I. Microscopy and ultrastructural pathology (author's transl)].

Fifty-seven thymomas, defined as neoplasms of the epithelial-reticular framework cells of the thymus, were assessed in respect to histologic type, inclusive of there ultrastructural aspects. The median age of the 57 patients was 40.4 years, with a range of 2 1/2--72 years. All neoplasms were located in the anterior mediastinum. The tumours in 40 cases were encapsulated and without invasion of adjacent tissue or implants (equal to non-invasive thymomas). The tumors in 17 cases were invasive of adjacent tissue, particularly mediastinal pleura, pericard and trachea. Six of 57 patients (equal to 10.5%) with thymomas have had a thoracic and supraclavicular lymph node metastasis, and osteolytic metastases in the vertebrae and sternum. Thirty-seven (equal to 64.9%) were so-called lympho-epithelial, 7 (equal to 12.3%) pure epithelial, 4 (equal to 7.0%) atypical (or anaplastic) with granulomatous focuses, 3 (equal to 5.3%) carcinoid and one (equal to 1.8%) seminomatous tumors. One patient have had a thymic cyst as a tumor-like conditions of the thymus, and four patients (equal to 7.0%) have had a thymo-lipoma. The histologic type of thymoma had no proof value in predicting prognosis with the exception of the so-called atypical or anaplastic thymoma. The fine structural aspects of thymomas and the fine structural differential diagnosis of anterior mediastinal tumors are discussed.

A correlation of the endoscopic and pathological changes in subclinical pathology of the horse's larynx.

The larynges of 6 horses were examined endoscopically and the findings correlated with the gross and histological appearance of the intrinsic laryngeal muscles and their nerve supply. In all cases it appeared that the balance between abductor and adductor muscle groups had been lost due to preferential atrophy of individual muscles or groups of muscles. The laryngeal abnormalities recorded were asymmetry of the larynx with asynchronous left sided abduction and fluttering or trembling of the left vocal cord and arytenoid cartilage. It is suggested that these changes represent the early signs of a progressive lesion which may result in left sided laryngeal hemiplegia.

Radiologic-pathologic correlation from the Armed Forces Institute of Pathology. Lymphangiomyomatosis.

The radiologic patterns caused by interstitial lung disease evoke a long list of differential diagnostic possibilities. Though the problem may at first seem insoluble, subdivision into conditions that spare the pulmonary architecture, as opposed to those that lead to an end-stage "honeycomb lung", and consideration of the clinical findings will frequently narrow down the list. Occasionally, key associated findings such as pleural effusion, pneumothorax, and systemic involvement of many organs will help rule out inappropriate diagnoses. Lymphangiomyomatosis is a rare cause of "honeycomb lung" that may result in a very specific combination of radiologic and clinical findings.

Radiologic-pathologic correlation from the Armed Forces Institute of Pathology. Inflammatory fibroid polyp.

The inflammatory fibroid polyp of the stomach, sometimes called eosinophilic granuloma, is a relatively uncommon lesion usually presenting a solitary, benign-appearing filling defect. The differential diagnoses include polypoid adenocarcinoma, hyperplastic mucosal polyp, adenoma, leiomyoma, epitheliod leiomyoma and leiomyosarcoma, and aberrant pancreas. Although difficult to distinguish by gross morphologic features, the inflammatory fibroid polyp shows a distinctive inflammatory response of the mucosal stroma in which eosinophils may be prominent. It is unrelated to the eosinophilic granuloma of lung or bone.

Pathology of Kawasaki disease: I. Pathology and morphogenesis of the vascular changes.

Histopathological investigation of the vascular changes in Kawasaki disease was carried out on thirty-seven autopsied Japanese patients. Arterial lesions could be classified into following five stages from the view point of morphogenesis of arteritis; 1) endothelial degeneration and increased vascular permeability, 2) edema and degeneration of the media, 3) necrotizing panarteritis, 4) granulation formation, and 5) scarformation. Aneurysm with thrombus was observed mainly in the coronary artery in most patients. It is considered that the initial changes begins in the endothelial cells with increased vascular permeability. Platelet aggregation in the damaged endothelial cells seems to play an important role in the further development of the arteritic changes. Vascular lesions were observed not only in the arterial system but also in the venous system, therefore Kawasaki disease is a systemic vasculitis rather than a systemic arteritis.

[Acute primary ischemic enteritis and colitis. Clinico-pathological and physio-pathological findings].

By opposition to acute post-operative ischaemic enterocolitis, the authors isolate, with the aid of seven cases, the intestinal lesions which spontaneously occur on the small intestines and on the colon and due to an ischaemic mechanism without thrombosis of the mesenteric vessels. After the description of clinical and anatomical features, they point out the main part of the vascular factor in the genesis of the lesions.
