[Synovial hemangioma of the knee joint--a rare cause of recurrent hemarthrosis].

In the differential diagnosis of bloody knee joint effusions synovial haemangioma as a rare cause has to be considered. Especially suspicious are long durations of disease with recurrent atraumatic blood-stained joint effusions and repeated episodes of painful limitation of motion, laboratory and radiographic findings often being normal. On the one hand arthroscopy can prove the diagnosis by obtaining an ample biopsy specimen, on the other hand it facilitates the healing of the lesion at the same time by radical removal of the tumour.

[Histiocytosis X. Problems of differential diagnosis in adults].

A now 20-year-old man has been suffering from diabetes insipidus for four years. Two years ago a tumour in the hypophyseal stalk-hypothalamus region had been removed, but no definitive histological diagnosis could be established. When aged 19 he developed cutaneous changes which for the first time led to histiocytosis being suspected. Also for the first time, multiple small foci were noted in both lungs. Histological examination of a transbronchial lung biopsy demonstrated histiocytosis X. No specific treatment is being considered at present, because the patient is symptom-free and has normal lung function.

[Endoscopic and histological alterations of the gastric mucosa in patients with chronic renal insufficiency (author's transl)].

Biopsies of mucosa from all regions of the stomach were obtained with endoscopic guidance from two groups of people. One group consisted of 80 patients who suffered from chronic renal insufficiency in various stages and had not yet been dialysed. The other group consisted of 80 healthy individuals. Both groups had the same age distribution. Histological examinations of the biopsies did not reveal significant differences between the two groups. The same was true for macroscopic examinations of stomach and duodenum. Changes indicating a so called "uremic gastritis" were not observed.

Exfoliative cytology of multiple endobronchial granular cell tumor.

A multicentric endobronchial granular cell tumor (GCT) in a 50-year-old man was diagnosed by the cytologic study of bronchial lavage specimens. The paraffin-embedded sections contained small clusters of medium-sized round tumor cells that had eccentric nuclei without nucleoli and eosinophilic finely granulated cytoplasm, which was positive with the periodic acid-Schiff stain. These cells were distinguishable from the macrophages and bronchial and squamous cells also found in the specimens. The excised tumors histologically mimicked a squamous cell carcinoma. Since 10% of all GCTs occur in the lung, where a multiple presentation can especially mimic a metastatic malignant process, it is important that the possibility of a granular cell tumor be considered in the screening of exfoliative cytologic specimens from the lung.
