Chondroblastoma of the temporal bone: a clinicopathologic study of five cases. (1/41)
Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6 years). All cases involved the temporal bone. Three involved the left side and two the right. Chief complaints were long-standing localized pain and hearing difficulty. A sharply demarcated lobulated mass was the main radiological finding. Microscopic findings were those of chondroblastoma of usual locations. Two cases showed aneurysmal bone cyst-like areas. Immunohistochemical studies for CD34, CD99, S-100 protein and cytokeratin were performed. Tumor cells were diffusely positive for S-100 protein in three cases and weakly positive for cytokeratin in one case. CD34 and CD99 were negative in all cases. In summary, chondroblastoma of the temporal bone is rare and occurs in older age group than reported cases of chondroblastoma of the usual location in the literature. (+info)Extendible replacements of the proximal tibia for bone tumours. (2/41)
Limb salvage is now customary in the treatment of primary bone tumours. The proximal tibia is a frequent site for these neoplasms but reconstruction, especially in children, is a formidable challenge. We reviewed 20 children with extendible replacements of the proximal tibia, all with a minimum follow-up of five years. Five died from their disease and, of the remaining 15, four had above-knee amputations for complications. Infection occurred in seven patients; in five it was related to the lengthening procedure. Aseptic loosening is inevitable in the younger children and only two have avoided a revision, amputation or other major complication; both were aged 12 years at the time of the initial surgery. Despite this, 11 children are alive with a functioning leg and a mean Musculoskeletal Tumour Society functional score of 83%. The lengthening mechanisms used in our series required extensive open operations. We are now using a simpler, minimally invasive, technique which we hope will decrease the incidence of complications. At present, the use of extendible prostheses of the proximal tibia remains an experimental procedure. (+info)h-Caldesmon as a specific marker for smooth muscle tumors. Comparison with other smooth muscle markers in bone tumors. (3/41)
Caldesmon is a protein widely distributed in smooth and non-smooth muscle cells and is thought to regulate cellular contraction. Its isoform, high-molecular-weight caldesmon (h-CD), was demonstrated to be specific for smooth muscle cells and smooth muscle tumors of the soft tissue and to never be expressed in myofibroblasts. We performed an immunohistochemical study to examine h-CD expression in the following bone tumors: conventional and non-conventional osteosarcoma, 13; malignant fibrous histiocytoma of bone, 5; giant cell tumors of bone, 5; chondroblastoma, 3; metastatic leiomyosarcoma, 2; and rhabdomyosarcoma, 1. Frequent immunoreactivity for muscle actin (alpha-smooth muscle actin or muscle-specific actin) was seen in 11 of 13 osteosarcomas and all other tumors, whereas h-CD was expressed intensely only in 2 leiomyosarcomas. h-CD is considered a specific and useful marker to distinguish smooth muscle tumor from bone tumors with myoid differentiation. (+info)Benign chondroblastoma of bone. Report of a case. (4/41)
A benign chondroblastoma of bone is reported. It was unusual because it occurred in an old lady, in a toe, and it was not painful and radiologically resembled a chondroma. The coarsely lobulated tumour showed a varied microscopic appearance, but it consisted chiefly of closely packed sheets of small, round polygonal or fusiform cells. There was some calcification present. The literature is reviewed. (+info)Chondroblastoma of a metacarpal bone mimicking an aneurysmal bone cyst: a case report and a review of the literature. (5/41)
Chondroblastoma of the metacarpal bone has been extremely rare and only seven cases have been reported in the English literature. Here we reported the eighth case of a chondroblastoma that developed on the first metacarpal bone of the right hand of a 21-year-old man. Radiographs showed an expansile osteolytic lesion with a multilocular appearance. In MR images, the lesion showed low intensity in T1 and high intensity in T2-weighted images with multiple fluid-fluid levels, which are findings resembling those of an aneurysmal bone cyst. From the pathological findings, however, it was recognized as a chondroblastoma with aneurysmal bone cyst-like change. Good clinical results was obtained by the subtotal resection of the metacarpal bone with a columnar-shaped iliac bone graft. (+info)Coexisting chondroblastoma and osteochondroma: a case report. (6/41)
The coexistence of two different types of benign cartilaginous tumours of bone in the same patient has not been reported in literature. We report a case in which a sixteen-year-old male had a benign chondroblastoma of the proximal left humerus and an osteochondroma of the distal left femur. Both originated at the same time and had a progressive increase in size with growth. (+info)Chondroblastoma of the temporal base with high mitotic activity. (7/41)
A 24-year-old man presented with a rare chondroblastoma of the temporal base manifesting as local pain accompanied by difficulty in opening the mouth. Gross total removal was achieved at initial surgery, but the tumor demonstrated rapid and destructive regrowth from a very small residual volume without definite histological malignant transformation. Growth activity estimated by MIB-1 staining increased spontaneously from 2.5% at the initial operation to 18.7% at recurrence. Further extensive radical tumor removal by surgeons from multiple disciplines was performed. The patient has been free of recurrence for 3 years without radiotherapy. Chondroblastoma of the temporal bone is widely accepted as a benign tumor and regrowth after gross total removal is very rare. However, some cases of chondroblastoma have potentially high mitotic activity. (+info)Skull base chondroblastoma: a case report. (8/41)
Chondroblastoma is a rare tumor of the skull. Temporal bone is the commonest site of involvement in the skull. We present a thirty one year old man who presented with painless swelling over the left temporal bone, which was near totally excised after preoperative embolization. Management of this unusual tumor and its complications are discussed. (+info)The tumor usually appears as a well-defined lump or mass that is surrounded by a fibrous capsule. The surface of the tumor may be smooth or rough, and it may be covered with cartilage or bone. Chondroblastoma tends to grow slowly over time, but it can sometimes become malignant and invade surrounding tissues.
Chondroblastoma is most commonly found in young adults, typically between the ages of 20 and 40. The exact cause of chondroblastoma is not known, but it may be linked to genetic factors or environmental exposures. Treatment usually involves surgery to remove the tumor, followed by radiation therapy or chemotherapy to prevent recurrence.
Some of the common symptoms of Chondroblastoma include:
* Painless lump or mass in the affected limb
* Limited mobility and stiffness in the affected joint
* Swelling and redness in the affected area
* Warmth and tenderness to touch
Some of the common diagnostic tests for Chondroblastoma include:
* X-rays
* CT scans
* MRI scans
* Biopsy
It's important to note that while chondroblastoma is a benign tumor, it can recur in some cases. Therefore, regular follow-up appointments with your doctor are essential to monitor the condition and detect any signs of recurrence early on.
Surgery is often necessary to treat bone cysts, aneurysmal, and the type of surgery will depend on the size and location of the cyst. The goal of surgery is to remove the cyst and any associated damage to the bone. In some cases, the bone may need to be repaired or replaced with a prosthetic.
Bone cysts, aneurysmal are relatively rare and account for only about 1% of all bone tumors. They can occur in people of any age but are most commonly seen in children and young adults. Treatment is usually successful, but there is a risk of complications such as infection or nerve damage.
Bone cysts, aneurysmal are also known as bone aneurysmal cysts or BACs. They are different from other types of bone cysts, such as simple bone cysts or fibrous dysplasia, which have a different cause and may require different treatment.
Overall, the prognosis for bone cysts, aneurysmal is generally good if they are treated promptly and effectively. However, there is always a risk of complications, and ongoing follow-up with a healthcare provider is important to monitor for any signs of recurrence or further problems.
Some common types of bone neoplasms include:
* Osteochondromas: These are benign tumors that grow on the surface of a bone.
* Giant cell tumors: These are benign tumors that can occur in any bone of the body.
* Chondromyxoid fibromas: These are rare, benign tumors that develop in the cartilage of a bone.
* Ewing's sarcoma: This is a malignant tumor that usually occurs in the long bones of the arms and legs.
* Multiple myeloma: This is a type of cancer that affects the plasma cells in the bone marrow.
Symptoms of bone neoplasms can include pain, swelling, or deformity of the affected bone, as well as weakness or fatigue. Treatment options depend on the type and location of the tumor, as well as the severity of the symptoms. Treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these.
Femoral neoplasms refer to abnormal growths or tumors that occur in the femur, which is the longest bone in the human body and runs from the hip joint to the knee joint. These tumors can be benign (non-cancerous) or malignant (cancerous), and their impact on the affected individual can range from minimal to severe.
Types of Femoral Neoplasms:
There are several types of femoral neoplasms, including:
1. Osteosarcoma: This is a type of primary bone cancer that originates in the femur. It is rare and tends to affect children and young adults.
2. Chondrosarcoma: This is another type of primary bone cancer that arises in the cartilage cells of the femur. It is more common than osteosarcoma and affects mostly older adults.
3. Ewing's Sarcoma: This is a rare type of bone cancer that can occur in any bone, including the femur. It typically affects children and young adults.
4. Giant Cell Tumor: This is a benign tumor that occurs in the bones, including the femur. While it is not cancerous, it can cause significant symptoms and may require surgical treatment.
Symptoms of Femoral Neoplasms:
The symptoms of femoral neoplasms can vary depending on the type and location of the tumor. Common symptoms include:
1. Pain: Patients with femoral neoplasms may experience pain in the affected leg, which can be worse with activity or weight-bearing.
2. Swelling: The affected limb may become swollen due to fluid accumulation or the growth of the tumor.
3. Limited mobility: Patients may experience limited mobility or stiffness in the affected joint due to pain or swelling.
4. Fracture: In some cases, femoral neoplasms can cause a fracture or weakening of the bone, which can lead to further complications.
Diagnosis and Treatment of Femoral Neoplasms:
The diagnosis of femoral neoplasms typically involves a combination of imaging studies and biopsy. Imaging studies, such as X-rays, CT scans, or MRI scans, can help identify the location and extent of the tumor. A biopsy may be performed to confirm the diagnosis and determine the type of tumor.
Treatment for femoral neoplasms depends on the type and location of the tumor, as well as the patient's age and overall health. Treatment options may include:
1. Observation: Small, benign tumors may not require immediate treatment and can be monitored with regular imaging studies to ensure that they do not grow or change over time.
2. Surgery: Many femoral neoplasms can be treated with surgery to remove the tumor and any affected bone tissue. In some cases, this may involve removing a portion of the femur or replacing it with a prosthetic implant.
3. Radiation therapy: This may be used in combination with surgery to treat more aggressive tumors or those that have spread to other areas of the body.
4. Chemotherapy: This may also be used in combination with surgery and radiation therapy to treat more aggressive tumors or those that have spread to other areas of the body.
5. Targeted therapy: This is a type of chemotherapy that targets specific molecules involved in the growth and progression of the tumor. Examples include denintuzumab mafodotin, which targets a protein called B-cell CD19, and olaratumab, which targets a protein called platelet-derived growth factor receptor alpha (PDGFR-alpha).
6. Immunotherapy: This is a type of treatment that uses the body's own immune system to fight cancer. Examples include pembrolizumab and nivolumab, which are checkpoint inhibitors that work by blocking proteins on T cells that prevent them from attacking cancer cells.
The prognosis for patients with femoral neoplasms depends on the type and location of the tumor, as well as the patient's age and overall health. In general, the prognosis is better for patients with benign tumors than those with malignant ones. However, even for patients with malignant tumors, there are many treatment options available, and the prognosis can vary depending on the specifics of the case.
It's important to note that these are general treatment options and the best course of treatment will depend on the specifics of each individual case. Patients should discuss their diagnosis and treatment options with their healthcare provider to determine the most appropriate course of action for their specific situation.
Examples of Skull Neoplasms include:
1. Meningioma: A benign tumor that arises from the meninges, the protective covering of the brain and spinal cord.
2. Acoustic neuroma: A benign tumor that grows on the nerve that connects the inner ear to the brain.
3. Pineal parenchymal tumors: Tumors that arise in the pineal gland, a small endocrine gland located in the brain.
4. Craniopharyngiomas: Benign tumors that arise near the pituitary gland, which regulates hormone production.
5. Medulloblastoma: A malignant tumor that arises in the cerebellum, a part of the brain that controls movement and coordination.
6. Germ cell tumors: Tumors that arise from immature cells that form in the embryo. These can be benign or malignant.
7. PNETs (primitive neuroectodermal tumors): Malignant tumors that arise from early forms of nerve cells.
8. Astrocytomas: Tumors that arise from the supportive tissue of the brain called astrocytes. These can be benign or malignant.
9. Oligodendrogliomas: Tumors that arise from the supportive tissue of the brain called oligodendrocytes. These can be benign or malignant.
10. Melanotic neuroectodermal tumors: Rare, malignant tumors that contain pigmented cells.
The hallmark of GCTB is its large size, with tumors often measuring several centimeters in diameter. The tumor cells are giant cells, which are larger than normal osteoblasts, and they have a distinctive "salt and pepper" appearance under the microscope due to the mixture of light and dark-staining cytoplasmic granules.
The clinical presentation of GCTB varies depending on the location and size of the tumor. Large tumors can cause symptoms such as pain, swelling, and limited mobility in the affected limb. Smaller tumors may not cause any symptoms and may be incidentally discovered on imaging studies performed for other reasons.
GCTB is a slow-growing tumor, and the exact cause of its development is unknown. Genetic mutations have been identified in some cases, but the exact mechanisms underlying GCTB remain unclear. Treatment options for GCTB include surgery, radiation therapy, and chemotherapy, depending on the size and location of the tumor and the patient's overall health.
In conclusion, giant cell tumor of bone is a rare and benign bone tumor that can occur in any bone of the body. It is characterized by its large size and distinctive histopathological features. Treatment options vary depending on the size and location of the tumor and the patient's overall health.
