User :   i am a 30 yr old male who coaches football,after getting mri on knee they found tumor that they think is chrondoblastoma , then after cat scan it reads Mildly expansile lytic mass of the distal metaphysis and epiphysis of the femur anterolaterally.The mass has a homogeneous internal matrix.The differential diagnosis includes chrondroblastoma,brown tumor if the patient has renal osteodystrophy,and less likely giant cell tumor,unicameral bone cyst,plasmocytoma(malingnent),and even less likely metastasis.just scaredof malignent.Any feed back wqould help of your thoughts
Doctor :   Hi,
Doctor :   Let me read your query for few minutes to be able to have a good discussion here.
User :   hello just want to hear if im in the danger part of this tumor or if you believe it to be benign
Doctor :   its a benign tumour
Doctor :   and a slow growing typr
Doctor :   type*
Doctor :   but has lot tendency to get converted to osteosarcoma a malignant variety
User :   what leads you to believe this to be benign
Doctor :   the Chondrblastoma is a benign variety by nature
User :   i know i am asking what makes you think its chondrobastoma over the others
Doctor :   the site and the homogenous appearance are typical
User :   does homogenous appear in malignent tumors as well
Doctor :   no , not commonly
Doctor :   the malignant are almost heterogeneous type
User :   what does homogenous internal matrix mean
Doctor :   it means the tumor is filled up with same type of tissue
User :   so the homogenous is a good word for benin tumors
Doctor :   in malignant variety since the growth is fast and invasive type , it produces mixed variety of tissues
Doctor :   yes, it is a good word
User :   im confused are you saying if it was malignant it would not have the same substance in the tumor and it would consist of more than one
Doctor :   yes, more than one because the malignant tumor will invade the surrounding tissue and destort the anatomy givign
a hetero appearence
User :   another question you say it is slow growing but my knee is getting more painful everyday,is that a bad sighn or common or what,cant hardly walk now

but i will surely help you
User :   are you there
Doctor :   yes, very much
User :   did you read last question
Doctor :   the pain will be due to the physical pressure of the tumour not contributing to the prognosis of the tumors always
User :   i due have a fracture i bet that causes some
Doctor :   yes, it could be due top that
Doctor :   to*
User :   being in my knee will they have to amputate my leg,i read about bone grafting
Doctor :   depends on the size of the tumor purely
User :   it takes up the one side of the club at end of femur
Doctor :   Xray will be the best way to confirm the size and the involvement details
User :   i have seen them that why i ask
