Case study (multiple photos): Nearly 60 years old, a cancer (squamous cell carcinoma) was removed from the entire right vocal cord three months earlier. He still had a hoarse voice and a red bump on the vibrating edge of his right vocal cord. I felt it was likely that he may have been talking and causing the vocal cord to vibrate, traumatizing the edge of the vocal cord before it was fully healed. This causes capillaries to grow into a ball, which is called a granuloma. He wish to have it removed, though it is common that they will fall off over a few months. We used a KTP laser and ablated the capillaries. The lowest picture is four months later. The capillaries on the right vocal cord are irregular, which is typical after the an extensive surgery like this.


Summary: 
Granulomas are a type of capillary abnormality. They usually occur in a location where there has been or is some ongoing trauma.
