Must come from an indexed, peer-reviewed journal. Rad Review Mondays from 5-7 PM, review cases from radiology practice of Dr. Fox. Bone Tumors Classication system not found in Yochum & Rowe see handouts. KNOW this to get the foundation for going forward!! General: 1. A tumor is an oma; dened as an abnormal cellular growth; growth of cells can be uncontrolled or can be controlled. If its controlled, called a benign tumor; benign = controlled and not malignant. Malignant is uncontrolled growth. Benign doesnt mean insignicant/forget about it! Some benign things will still destroy joints, etc. 2. Secondly, bone is a multi-cellular tissue. A n y c e l l f o u n d i n b o n e c a n p r o d u c e a t u m o r t h e r e . If it originates from the bone, it is classied as a bone tumor, whether it comes from b o n e c e l l s or not, i.e. tumors from cartilage cells are still bone tumors if it originates from the bone. 3. Malignant bone tumors = BAD, VERY BAD, but luckily they are not very common. (Below is from Week 2 but moved up here b/c this is general info about tumors details from other weeks included in Classication outline below) 4 major questions to ask about tumors 1. Whats the radiographic appearance? 2. Where is it located? (epiphysis, diaphysis, etc.) 3. What is patients age? Differential may be totally different based on age 4. Does it hurt or not? (symptoms) Site M o s t t u m o r s o c c u r i n t h e m e t a p h y s i s ! Remember what happens in the epiphysis and the diaphysis b/c shorter lists and know everything else happens in the metaphysis (table A on p. 2 of Handout 2 my numbering system) *Learn these and know everything else is in the Metaphysis! Age B e n i g n t u m o r s : If its a benign originating tumor, almost always happen before the age of 30. If they are symptomatic, get discovered soon, but if not symptomatic, may not see until age 45; still benign and started in 30s, just not found until the 40s. One exception is the Giant Cell Tumor, largely benign, sometimes malignant originate most of the time between 20-40 years old. ClassiFed in decades 2 nd decade = teens, 3 rd decade = 20s, etc. careful with this! W i t h m a l i g n a n t t u m o r s ( t o p 5 ) : 1. Multiple Myeloma 40 years and beyond, most are 50-70 years old 2. Osteosarcoma and Ewings majority under 30, peak is 2 nd decade (teenage years) 3. Chondrosarcoma and ibrosarcoma usually 30-60 years old (over 30 but not usually in an 80 year old) Metastasis can happen at any age but usually over 40....
