[Enzyme histochemical and immunopathological findings in intrathoracic lymph node sarcoidosis (author's transl)].

Comparative investigations on the value of modern morphological methods (enzyme-histochemistry, immunopathology) are carried out in 40 patients with intrathoracic lymph node sarcoidosis. These studies show that by means of enzyme-histochemical and immunopathological methods additional knowledge is got in comparison with routine histology, concerning especially the floridity of the disease, humoral immunity and collagen synthesis. This information is an important factor for both the clinical assessment of the process and an effective therapy.
