Carcinosarcoma of the Mediastinum: A Rare Cause of Vocal Cord Palsy and Progressive Dysphagia.

Carcinosarcoma is a rare type of malignant tumour that possess both the elements of carcinoma and sarcoma. They may occur in various locations such as the uterus, breast, thyroid, lung and gastrointestinal system. However, very few primary mediastinal carcinosarcomas have been reported. We are presenting a case of a 75-year-old male who presented with progressive dysphagia and hoarseness for 3 weeks. Contrast-enhanced computed tomography of the neck showed features of enlarged mediastinal necrotic nodes and the biopsy of this mass showed morphology and immunohistochemical profile that are consistent with carcinosarcoma. However, the patient succumbed to his illness soon after diagnosis.
