54)Which of the following pathologic processes in an example of dysplasia?

A. Actinic keratosis
B. Chronic cystitis
C. Chronic bronchitis
D. Ulcerative colitis
Ans:A
Explanation
General Pathology-Cell Pathology-Actinic keratosis is a form of dysplasia in sun-exposed skin. Histologically, such lesions are composed of atypical squamous cells, which vary in size and shape. They show no signs of regular maturation as the cells ,move from the basal layer of the epidermis to its surface. Dyplastic epidermis shares many features with squamous cell carcinoma, and untreated actinic keratosis often gives rise to invasive cancer. Chronic cystitis and bronchitis may result in foci of metaplasia, but these tend to be composed of differentiated cells that show no nuclear atypia. Squamous metaplasia of the columnar epithelium of the bronchi or the transitional epithelium of the urinary bladder may become dysplastic, but this transition is unpredictable. Therefore, these metaplastic lesions should not be grouped together with actinickeratosis, which is often reffered to as “Squamous cell carcinoma, one half”. Although dyplasia and even neoplasia can occur in the colonic mucosa affected by ulcerative colitis or in the columnar epithelium of Barrett’s esophagus, by itself neither ulcerative colitis nor Barrett’ esophagus should be classified as dysplasia.
