[Alveolar soft tissue sarcoma].
An autopsy observation of alveolar soft tissue sarcoma of the left hip muscles in a man of 66 is described. Predominantly lymphogenic metastasizing of the alveolar sarcoma was observed and two hypes of tumour cells, "dark" and "light" were distinguished. PAS-positive substances, lipids and mucus were found in the cytoplasm of the "light" cells. Histogenetically, the alveolar soft tissue sarcoma is assumed to be close to striated muscles.
