Pseudosarcoma of the oesophagus. A case report.

Pseudosarcoma is a malignant, polypoid tumour which has been described in the oesophagus, mouth, fauces and larynx. The tumour consists of a special variety of squamous cell carcinoma. Although squamous carcinoma of the oesophagus is especially prevalent in the East London area, there does not appear to be a corresponding increase in the incidence of pseudosarcoma. We report a case of pseudosarcoma encountered in a series of 5 000 cases of squamous carcinoma of the oesophagus.
