Hyperplasia
• Hyperplasia is
A. Increase in size of cells
B. Decrease in size of cells
C. Increase in number of cells
D. Decrease in number of cells
E. Change in type of cells
C. Increase in number of cells
Who am I??
An adaptive, reversible change in which one adult “mature, differentiated” cell type is replaced by another of the same category (epithelial or mesenchymal)
Metaplasia
A 5-year-old boy suffers blunt trauma to the leg in an automobile accident. Six month later, bone trabeculae have formed within the striated skeletal muscle tissue at the site of injury. This pathological condition is an example of which of the following morphological adaptations to injury?
A) Atrophy
B) Dysplasia
C) Metaplasia
D) Metastatic calcification
E) Dystrophic calcification
C) Metaplasia
Who am I?
I am a non-neoplastic, disordered epithelial cell proliferation. (Loss of uniformity in a population of cells and disorder of their normal architecture)
A lesion that has the morphologic features of cancer but is confined within the original basement membrane is:
• Hyperplasia
• Metaplasia
• Dysplasia
• Carcinoma insitu
• Neoplasia
• Carcinoma insitu
Urothelium ; Discriminate the sequence of events
Urothelium ; Discriminate the sequence of events
Classify tumours aaccording to the tissue of origin
Tumors according to biological behaviour
- Benign
- Malignant
A 19 year old boy has a huge leg mass which has been discovered few weeks ago and grows rapidly fixing the knee joint. Above knee amputation is preformed and is sent for histopathological evaluation.
What are the mechanisms of spread of malignant tumors ?
