What is a polypoidal lesion?

A polypoidal lesion is a growth that protrudes from a mucosal surface, resembling a polyp. It can be found in various organs, such as the gastrointestinal tract, respiratory system, or urinary tract. These lesions can be benign or malignant and may vary in size, shape, and appearance. Diagnosis typically involves imaging studies or biopsy to determine the nature of the lesion.
