Abstract: | A case report of a primary laryngeal malignant mesenchymoma, a very rare head and neck and even rarer laryngeal lesion, is reported. In this case, an 85-year-old man, who had undergone several panendoscopies and biopsies that were non-diagnostic, subsequently succumbed to pulmonary metastases and died from respiratory failure. At autopsy, tumour cells were demonstrated to constitute both bone and striated muscle cell types. As the tumour cells differentiated into two types of specialized cells from one type of embryonal tissue, the diagnosis of malignant mesenchymoma was established. |
