67 year old male, non smoker, presented with hoarseness of voice more for last 6 months. he has history of tonsillectomy in 1967 and two times vocal cord biopsy in 2000 and 2005 which was negative for malignancy. Voice is more or less same for last 6 months. This video shows a mall over left vocal cord posteriorly. Now my question is whether this mass should be touched with MLS or we just observe it or treat with steroids. Please state exact diagnosis too.
