Abstract

A Case report of a laryngeal malignant mesenchymoma, a very rare head and neck and even rarer laryngeal leison, is reported.

In this case, an 85-years-old man, who had undergone several panendoscopies and biopsies that were non-diagnostic, subsequently succumbed to pulmonary metastases and died from respiratory failure. At autospy, tumour cells were demonstrated to constiute both bone and straited muscle cell types. As the tumour cells differentiated into two types of specialized cells from one type of embryonal tissue, the diagnosis of maligant mesenchymoma was established.
