title: [Pseudosarcomatous fusiform cell epithelioma of the oral cavity. Apropos of 5 cases].
abstract: Pseudo-sarcomatous spindle cell carcinomas are a variety of squamous carcinoma which must be recognized since they may raise the difficult problem of histological identification. They may be confused with a sarcomatous tumour, in particular fibroblastic. Buccal involvement, somewhat rarer than other sites in the upper respiratory and digestive tract, is nevertheless not exceptional. Clinically the lesion may be either a relative superficial polypoid mass, where the prognosis is relatively favourable, or a highly infiltrating lesion, which applied in the five cases reported here and which then has a rapid course and bad prognosis.
