title: [Myospherulosis: a riddle asked by strange bags of marbles. A report of four cases (author's transl)].
abstract: Four cases of "myospherulosis" are presented with a review of the thirty cases previously reported in the litterature. The disease is characterized by clusters of spherules, surrounded by a thin membranous bag, within a multicystic reaction of muscular and subcutaneous tissue or of paranasal sinuses. The actual nature of these spherules still remains unknown. Several pathogenic hypothesis are suggested.
