case_images: Full head and neck examination was performed including flexible laryngoscopy revealing a mass emanating from the left supraglottic part of larynx without erosion or haemorrhage and a lesion of the true right vocal cold presenting as leukoplakia (Figure 1). Microlaryngoscopy and biopsy were performed (Figure 1).
case_images: Low-power view of the mass shows two neoplastic populations (sarcomatoid and epithelial component) and the overlying dysplastic epithelium (H&E, X40).

case_images: The cells of the two populations intermingled (Figure 4).
case_images: Small supraglottic mass just above the anterior commissure two months after initial treatment was excised with CO2 laser and proved to be a recurrence of histiocytoma. The patient remained disease-free nine months after the second look cordectomy.
