1- Diagnosis 👉🏻 osteoid osteoma

2- Causes 👉🏻 unclear

3- Common in 👉🏻
• Children, and young adults (most patients 5 - 24 years old)
• male more than female

●——●• OSTEOSARCOMA •●——●

#Definition
• Malignant tumor in which the cells synthesize bone
• Most common primary malignant solid tumor of bone (plasma cell myeloma is actually the most common primary bone tumor but it's not a solid tumor)
• Many types of osteosarcoma that differ based on the tumor's location (within the bone or on the surface of the bone) and the grade of the tumor (low grade, intermediate grade or high grade)

#Common features
• Bone is necessary for diagnosis (typically has a filigree microscopic appearance)
• Most cases occur in children (10 - 14 years old) and are primary; secondary osteosarcoma is most common in adults

#affected bone
• Osteosarcoma may arise in any bone
• Most common : long bones of extremities

#Clinical features
• Painful enlarging mass lesion is common

#Gross description
• originates from metaphysis of the proximal humerus, extends into surrounding soft tissues


#Microscopic description
- eosinophilic cytoplasm ( little )
- hyper-cellular
- hyper-chromatic nuclei ( large )
- spindle cells ( different sizes and shapes

س/ م فهمتش المقصود ؟!

ج/هنا علئ ما هوه مكتوب انه اول شي سبب هذا المرض هوه الطفره في جين FGFR3 الذي يعمل هذا الجين علئ تثبيط النموء الغضروفي وعند ما يحصل طفره فيه يعمل علئ تنشيط المستقبل وبهذا الطريقه يحدث التاثير الذي هوه كبح او تثبيط النموء ..

هذا مو مكتَوب ..
