Pseudosarcoma (polypoid sarcoma-like masses) associated with squamous-cell carcinoma of the mouth, fauces, and larynx.Report of ten cases

Abstract

HE term "pseudosarcoma" is not used in T this report, as it has been on occasion in the past, to describe carinomatous tissue with spindle-or other-shaped cells, so that the a p pearance resembles a sarcoma.13 Rather, the term "pseudosarcoma" is used by the author to indicate a presumably non-neoplastic connective-tissue mass with a histological appearance that is a t once bizarre, "alarming," and deceivingly suggestive of some fully malignant form of true sarcoma capable ol metastasis. Polypoid masses of such tissue were the presenting features in the ten cases of squamouscell carcinoma of the mouth, fauces, and larynx to be reported. T h e purpose of this paper is to point out the practical significance of these masses and to discuss their possible nature and relation to certain reported rases said to be carcinosarcoma.
