Alveolar soft-part sarcoma. A review on its histogenesis and further studies based on electron microscopy, immunohistochemistry, and biochemistry.

To date, the histogenesis of alveolar soft part sarcoma has been considered to be of paraganglioma origin, striated muscle cell origin, or as a malignant granular cell myoblastoma, neural neoplasm, or renin-producing tumor. Further studies for these existing theories were performed based on various methods. The negative formaldehyde-induced fluorescence and the immunohistochemical absence of neuron-specific enolase were against the paraganglioma theory. The immunohistochemical absence of myelin proteins (P2 protein and PO protein) and S-100 protein were against the malignant granular cell myoblastoma and neural neoplasm theory. Furthermore, there was a totally negative immunohistochemical finding for renin in the tumor cells, and the biochemical relationship of the tumor and renin was completely negated. The contradiction in a well-known report that the components of crystals were considered to be Z-band materials such as tropomyosin was referred to based on recent myological data. Concurrently, the absence of tropomyosin was immunohistochemically demonstrated. Hence, the issues on the histogenesis of alveolar soft part sarcoma and the identity of the characteristic crystalloids remain open for discussion.
