Peutz-jeghers polyp with several foci of glandular dysplasia: Report of a case

A case of Peutz-Jeghers syndrome in which one colonic polyp showed many foci of glandular dysplasia is reported. Peutz-Jeghers polyps are considered to be hamartomatous, and their malignant potential has been considered doubtful. This case is valuable because foci of glandular dysplasia existed within hyperplastic glands. Glands of Peutz-Jeghers polyps are proliferative in nature, and therefore it is not surprising that there are areas of glandular dysplasia and of cancerous change

Squamous cell metaplasia without dysplasia of the colonic mucosa in ulcerative colitis

We encountered a patient with squamous cell metaplasia and long-standing ulcerative colitis. The lesion was noted endoscopically as a pinkish white area with a clearly demarcated border. Lugol stain and biopsies demonstrated the lesion to be composed of squamous epithelium.
