Neoplasia
Neoplasia is the formation of new abnormal tissue that is not reversible
NEOPLASIA (large, high-yield topic — multiple essays target this)
- Neoplasia — abnormal, uncontrolled, autonomous cell growth that persists after the stimulus is removed
- Hypoxia — reduced oxygen delivery/availability to tissue
- Anoxia — complete absence of oxygen
- Necrosis — pathological, uncontrolled cell death with inflammation
- Apoptosis — programmed, controlled cell death without inflammation

Practice questions on Neoplasia
ONE of the following statements about vulvar intraepithelial neoplasia (VIN) IS TRUE:
- They are metaplastic conditions
- Squamous epithelium of the vulva shows dysplasia
- The diagnosis is based on a careful clinical inspection
- VIN IV, is the most severe form
- It is always associated with HPV infection
Answer: B. Vulvar intraepithelial neoplasia (VIN) is characterized by dysplastic changes within the squamous epithelium of the vulva.
An epidemiologic study is performed to determine potential risk factors for development of penile squamous intraepithelial neoplasia. It is observed that persons who develop this disease are elderly men. Which of the following diseases is most likely to be found to precede development of penile neoplasia in these men?
- Phimosis
- Herpes simplex virus infection
- Lichen simplex chronicus
- Balanitis xerotica obliterans
Answer: A. The chronic irritation from accumulation of secretions and smegma under the prepuce is the likely risk. Circumcision reduces the risk for development of penile carcinoma, and can reduce transmission of infections as well. ---
A 77-year-old man has a routine check-up. The only finding is slight nodularity of his prostate on digital rectal examination. Serum PSA is 6 ng/mL. A prostate biopsy shows prostatic intraepithelial neoplasia (PIN). Which of the following is the best medical care option to offer this man?
- Radical prostatectomy
- Multiagent chemotherapy
- Transurethral prostate resection
- Monitoring PSA levels
Answer: D. PIN is a potential precursor of prostatic adenocarcinoma, but by itself does not warrant therapy. ---
What is the definition of neoplasia?
- Inflammation of tissues
- Formation of new, abnormal growth of tissue
- Repair of damaged tissue
- Normal tissue regeneration
Answer: B. ** Neoplasia is defined as the formation of new, abnormal growth of tissue. The term comes from "neo" (new) and "plasia" (growth or formation). ---
What aspect of neoplasia deals with the study of disease distribution in populations?
- Aetiology
- Epidemiology
- Pathogenesis
- Morphology
Answer: B. ** Epidemiology deals with the study of disease distribution, patterns, and determinants in populations, including cancer incidence, prevalence, and risk factors. ---
What aspect of neoplasia deals with the study of disease causation?
- Aetiology
- Epidemiology
- Morphology
- Treatment
Answer: A. ** Aetiology (or etiology) is the study of disease causation, examining factors that cause or contribute to the development of neoplasms. ---
