Primary sarcoma of the gallbladder. A light and electronmicroscopical study.
Six Swedish cases of primary sarcoma of the gallbladder from the period 1958-1973 and 1 case from 1975 were studied by light and electron microscopy. the literature was reviewed for the period after 1970. Ultrastructural features of sarcoma were investigated in order to exclude poorly differentiated carcinoma. One case was considered to be an embryonal rhabdomyosarcoma, three cases leiomyosarcoma and two were diagnosed as fibrosarcoma. One case, diagnosed as sarcoma of the gallbladder by light microscopy, was omitted because electron microscopical examination revealed a squamous cell carcinoma.
