INTRODUCTION
Colorectal cancer (CRC) is the world’s third most common cancer. (1) The incidence of CRC is variable among high and low-income countries due to lifestyle differences and early detection in screening programs of premalignant lesions or polyps, the presentation of colorectal cancer is variable depending on the involved location across the colon with more than 50% of the patients die from their CRC cancer, metastasis is usually present in 20% at the time of diagnosis, most commonly identified site of metastasis is Liver, Lungs, and brain respectively, however, no clear information about the exact percentage of each metastasis as staging system usually stage them as stage IV without clarifying the involved sites. (2-6) Metastatic laryngeal cancers represent less than 1% of all laryngeal malignancies, with Skin melanoma and Renal cell carcinoma being the most common primary cancers to metastasize to the larynx as reported by fertile et al. in 1988, however, a recent review of the English literature showed that colorectal cancer metastasis to the larynx is the most common and compromise quarter of 41 cases. (3, 5) Dysphonia is the term used to describe any impairment or alteration of the voice with hoarseness; primarily, it is due to vocal muscle irregular oscillation owing to underlying muscle tension or dysfunction, incomplete closure of glottis on vocalization, or pressure effect excreted on the vocal folds by mass or tumor.
