case_images: The patient underwent total laryngectomy and wide excision of the trachea which included the second tumour within safe limits (Figure 2).
case_images: (a): The tumour of the glottis (left) and the trachea (right) share the same morphological features. (b): Haematoxylin-eosin stain shows groups of tumour cells in lymphatic vessels (left). Immunomicronhistochemical stain for D2-40 antigen shows positivity of the vascular endothelium, confirming that these are indeed lymphatics (right). (B: x200).
