An analysis was made of the rhabdomyosarcomas diagnosed in the Dept. of Pathology of the University of Groningen between 1971 and 1983. Ten cases diagnosed in patients over 30 years of age were studied in detail. After review the diagnosis was discarded on morphologic criteria in all cases. In 9 cases it was changed into malignant fibrous histiocytoma (MFH) and in one case this diagnosis was favoured, but inconclusive. In 5 cases immunohistochemical studies could be performed. In all cases staining for the muscle specific intermediate filaments desmin appeared negative and for the mesenchymal intermediate filaments vimentin positive. These cases were also positive for one or more of the histiocytic markers alpha-1-antichymotrypsin, alpha-1-antitrypsin and lysozyme. It is concluded that rhabdomyosarcoma in older patients is extremely rare and the possible relationship between MFH in the adult and rhabdomyosarcoma in childhood is discussed.
