[Calcifying epithelioma of Malherbe masquerading as a parotid-tumour (author's transl)].

3 cases of epithelioma calcificans Malherbe are being reported on, which were observed on children in the parotid area. The scarcity of such lesions in the regio parotidea is stressed, conclusions concerning differential diagnosis are following. The sometimes high concentration of mitoses is discussed under consideration of eventual diagnostic problems regarding cytological investigation.

[Clinical picture and morphology of orbital rhabdomyosarcomas in children].

The clinical course of orbital rhabdomyosarcoma is described in seven male children. A survey of the literature on the subject is given. Particular attention is paid to certain diagnostic problems of this most frequent orbital malignant primary in childhood. An adequate combination therapy which results in cure in more than half of the patients should be employed provided that an exact morphological diagnosis is made; this still causes often great difficulty. Electron microscopy is of great value in distinguishing this type of tumor from other malignancies, including the so-called reticulosarcoma. In comparison with the case material of other authors, there was a relatively high rate of late deaths in our patients.

[Histological and histochemical evaluation of the cellular infiltration of s.c. implanted sparks prothesis. Experiments on rats (authors transl)].

Sparks-prothesis of 3 mm diameter were implanted into inbred rats and withdrawn after one to ten weeks. They were then fixed in Formalin and embedded in Paraffin and Metachrylat. After cutting (2.5 mu), the histological and histochemical parameters were examined. Cellular infiltration was studied after a certain period of time. The basic results of the genesis of that infiltration are given as follows: during the first two weeks following the s.c. implantation, derivates of monocytes (cells which play an imminent and important role during arterial replacement) were found. After the third and fourth week collagenous and elastic fibers could be seen, the connective tissue became stronger. The most favorable time for grafting can be evaluated by these experiments.
