New tissue formation (abnormal proliferation)
-overgrowth of tissue to form a mass
What is neoplasia?
100
Inadequate development; tissue is immature and functionally deficient. Below-average number of cells.
What is hypoplasia?
100
Cancerous tumour, rapidly growing, not encapsulated, can metastasize, requires treatment.
What is a malignant tumour?
100
Benign tumour in glandular tissue.
What is adenoma?
100
Malignant tumour of fibrous connective tissue.
What is fibrosarcoma?
200
Enlargement of cells when demand increases but cell's can't divide.
What is hypertrophy?
200
Abnormal morphology. Cells have lost definition and normal function.
What is anaplasia?
200
Non-cancerous tumour, slow growing, encapsulated.
What is a benign tumour?
200
Malignant tumour in glandular tissue.
What is adenocarcinoma?
200
Malignant tumour in fat.
What is liposarcoma?
300
One cell type changes into another, usually due to unfavourable conditions.
-usually in epithelia, but also connective tissue
-usually reversible in epithelia
What is metaplasia?
300
Lack of organ development.
What is aplasia?
300
Tumour that has travelled from its primary site to a secondary or distant site.
What is a metastatic tumour (metastasis)?
300
Benign tumour in bone.
What is osteoma?
300
Malignancy in blood vessel tissue.
What is angiosarcoma?
400
Production of new cells via mitosis in response to growth stimulus, but in limited numbers.
-growth is controlled and matched to demand
What is hyperplasia?
400
Decrease in cell size due to low demand.
What is atrophy?
400
Malignant tumour arising in epithelial tissues (ectoderm or endoderm). Largest group of all malignant neoplasms.
What is carcinoma?
400
Malignant bone tumour.
What is osteosarcoma?
400
Malignancy in skeletal (striated) muscle.
What is rhabdomyosarcoma?
500
Growth of new, tougher, stratified, structurally disordered tissue (pleomorphic). Change in cell or tissue phenotype.
-large, dark-staining nuclei with increased mitosis rates.
What is dysplasia?
500
The study of tumours.
What is oncology?
500
Malignant tumour in connective tissue (mesoderm). Less common and worse prognosis.
