A case of pseudosarcoma associated with type 3 squamous cell carcinoma of the esophagus: report of a case.
A case of a primary esophageal pseudosarcoma associated with an independent type 3 tumor is described herein. A 60-year-old male presented with dysphagia and chest discomfort. A clinical evaluation revealed a type 3 tumor in the middle of the esophagus, which was diagnosed after a biopsy to be squamous cell carcinoma (SCC). A subsequent gross examination of the subtotally removed esophagus revealed a polypoid tumor adjacent to the type 3 tumor. Histologically, the polypoid mass was composed of SCC and mesenchymal components without a transitional zone. The tumor was thus classified as a pseudosarcoma of the esophagus, and was unique in that this appeared to have developed independently from the SCC.
