Intro and Principles of Soft Tissue Diagnosis- Exam I Flashcards
The medical science and specialty practice, concerned with all aspects of disease, but with special reference to the essential nature, causes, and the development of abnormal conditions, as well as the structural and functional changes that result from the disease processes:
Pathology
Probabilities from possibilities includes:
- All possible lesions for a patient of:
- All possible lesions from:
- All possible lesions that:
- this age, sex, & race
- this anatomical location
- look this way
Recognition requires a thorough knowledge of ____ and ____. This is also known as:
normal; “the range of normal”; WNL
Components of developing a differential diagnosis include:
- Recognition
- Description of the lesion
- Patient contribution
- Possibilities
- Probabilities
DDx:
Differential diagnosis
When making a differential diagnosis, patient contributions include:
- age, gender, race
- current medical conditions and meds
- supplements
- social habits
- oral habits
- past medical history
When you have a lesion that can only look a certain way- this is considered:
pathognomic
For diagnosis of a soft tissue lesion, what should be considered?
- texture/consistency
- association with surrounding tissue (fixed vs. movable, displacing vs. devouring)
For diagnosis of a soft tissue lesion, anatomic location:
