Introduction to General & Systemic Pathology Flashcards
An abnormal condition that may impair bodily function, cause discomfort, social problems, death:
disease
The cause of the disease process:
etiology
The mechanism of disease development (how it develops):
pathogenesis
Objective, something you see:
sign
Subjective, something the patient tells you:
symptom
A sign whose presence means that a particular disease is present beyond any doubt:
pathognomonic
The disease state of an individual; incidence (number) of illness in a population:
morbidity
Incidence (number) of death in a population:
mortality
Any type of clinical or molecular abnormality:
lesion
The biochemical and structural changes induced in cells and organs:
molecular and morphologic changes
The functional consequences of morphologic changes:
clinical manifestations
Irritation by biting cheek/tongue, a sharp tooth, etc. :
traumatic ulcer
White lesion that is irregular and thickened- can’t find a cause for it:
leukoplakia
lesion on tooth that may be xerostomia related:
carious lesion
Pigmented lesion, irregular in shape:
melanoma
The most common intraoral melanoma sites in adults is on the:
palate
- traumatic ulcer
- leukoplakia
- carious lesion
- melanoma
These are all types of:
lesions
A lesion may be invisible because it is:
- located deep within the body
- has molecular basis
Examples of invisible lesions due to have a molecular basis (biochemical lesions): (3)
- Diabetes melitus
- Schizophrenia
- Phenylketonuria (PKU)
PKU is an example of a ___ lesion
“invisible” biochemical lesion
- an autosomal recessive disorder of phenylalanine metabolism- a developmental disease
- caused by a mutation in the enzyme that converts phenylalanine to tyrosine (phenylalanine hydroxylase)
- Phenylalanine is toxic to developing brain and causes profound, irreaerisdlbe mental retardation (cognitive disorder)
Phenylketonuria

metabolic
- growth hormone-secreting pituitary adenoma (neoplasm)

- one of the most common ulcers
- T-lymphocytes destroy mucosal surface
Recurrent pathos stomatitis
Mucous membrane pemphigoid is an example of a ____ disease
immune mediated
- autoimmune disease affecting gingiva
- easy separation of overlying epithelium to underlying connective tissue with light stream of air
- AKA desquamative gingitivis
Mucous Membrane Pemphigoid
Pyogenic granuloma is an example of a ____ disease
reactive
- overgrowth of normal healing tissue
- reaction to an irritant- will go away when the irritant is removed (i.e., calculus)
pyogenic granuloma
gingival hyperplasia (commonly seen with DM patients) is an example of a ____ disease
reactive
(the DM part is a metabolic disease)
- gingival overgrowth caused by the underlying systemic disease along with an infection
- can be considered both reactive or metabolic
gingival hyperplasia- diabetes mellitus
