Alveolar soft part sarcoma: a report of two cases with some histochemical and ultrastructural observations.

Abstract

In a survey of all malignant soft tissue tumors in the extremities and limb girdles in Finland between 1960 and 1969, only one alveolar soft part sarcoma was found among 246 tumors (0.4%). Another alveolar soft part sarcoma, diagnosed in 1976, was more thoroughly studied. There was evidence that the characteristic crystals of alveolar soft part sarcoma are formed from the dense granules. Both were PASM-positive at ultrastructural level. No monoamines were detected in the cells by formaldehyde-induced fluorescence. This is a further fact to nullify the theory of the paraganglionic origin of alveolar soft part sarcoma, but the question of the histogenesis of the tumor still remains open.
