Overview

Anaplastic tumors have a high mitotic rate and lymphovascular invasion.[2] It rapidly invades surrounding tissues (such as the trachea). The presence of regional lymphadenopathy in older patients in whomneedle aspiration biopsy reveals characteristic vesicular appearance of the nuclei would support a diagnosis of anaplastic carcinoma.
