the uncontrolled growth of the bone tissues in the individual system of patient, bone tumors may be of any tissue or cell of the bone as it relative to the bone part,bone tumors may be of benign or malignant in nature. mostly bone tumors are the metastatic tumor they metastasize from other to the bone, other organs like lungs ,kidney , prostate,colon,breast,thyroid includes,neuroblastoma is the most common tumor that includes in metastatic property in children and adults,
Classification of Bone tumors
As bone tumors are the benign and malignant in nature so here below
1- Benign primary bone tumors
2- Malignant primary bone tumors
3- Benign cartilaginous tumors
4-Malignent cartilaginous tumors
Giant cell tumor
Benign type tumor,which does not proliferate into malignant form,this usually occurs in 40-50 years of age but not in the child,mostly affected parts are facial bones and skull of individual,the growing part of the bone attached to the relative bone,and histologically show similarities to the normal bone, this is the uncommon solitary tumor,mechanical problems
and cosmetic issues may seen in this type of tumor but did not undergo to the malignant form of tumor.
Benign type tumor of bone,this mostly affect the individual in age of 10 -20 years , in commonly vertebral column ,spinous process and transverse process of the vertebra, a patient complains of the pain in this type of tumor,it may affect the other part of the skeleton , in diagnosis with x-rays, it gives an appearance of the irregular lytic lesions.
benign type tumor,affecting the individual of 10-20 years,and mostly the femure and tibia affected,paient presenting severe pain in this type of tumor,circumscribed lesions are shown in x-rays ,this is a cortical type tumor
Malignant type tumor,affecting the individuals of 10-20 years, and proximal tibia,and hummus,and distal femur mostly knee area is the common site of this tumor,genetic abnormality is the main etiology of this tumor in which chromosomes involved,rapidly growing tumor may cause fracture of the bone,pain may or may not with bone mass in this condition.
Malignant type carcinoma of the older age, mostly above 40 years of the age , and involving the femur humerus and pelvis of the individual,this may b due to another disease as Paget disease, previous exposure to the radiations histologically similar to the primary osteoblastoma
benign type tumor of the bone, individuals of 10-30 years involved in this disease,with the affecting the metaphysis of long bones,lower femur and upper tibia mostly involved,having the malignant transformation.
(enchondroma)Benign type tumor of bone affecting the small bones of the skeleton-like hands and feet of individuals with age under 30-50 years,in the medullary region well-circumcised lesions are usually arisen uncommonly multiple and hereditary.
Malignant type of the tumor which mostly involved in the proximal femur,pelvis,ribs,shoulder,in age of 40-60 years but not in children,its affecting ratio in male and female is 2:1it is about 20 % affecting tumor of the bone X-rays show infiltration mass,its treatment is of surgery ,because this type of tumors resistant to the radiotherapy and chemotherapy
Giant cell tumor
this tumor is mostly a benign type tumor,affecting the individual of 20-40 years ,mostly seen in epiphysis of long bones, distal femur proximal tibia,proximal humerus, and distal radius also involved in many cases,X-rays shows bubble or soup appearance,lytic mass with transversed by thin sclerotic appearance,after surgical removal this giant type tumor have high rate of reoccurrence,
an uncommon type of sarcoma,in children and adults aging factor, is of 10–20 years,males more affected in such type tumor common sites involving are the long bones ribs, pelvis, vertebral, diaphysis and metaphysis,destructive lesions are a scene in the x-rays,Ewing’s type sarcoma spread rapidly by blood anywhere at the early stage ,and highly malignant neoplasia.
