Description. HMOCE (hereditary multiple osteochondral exostosis) is a rare, autosomal dominant inherited disease where multiple osteochondral bone tumors occur on the surfaces of the bones. The severity of the disease can vary from mild to very disabling. A small number of the tumors may develop into low grade chondrosarcomas. METASTATIC KIDNEY CANCER Kidney cancer metastasis most commonly affects the spine, ribs, pelvis, and proximal long bones. Kidney cancer may metastasize extremely late after the treatment of the primary lesion, up to ten years or more. Why the tumor seems to lay dormant for so long and then suddenly pop up in the bone is not known. Another unusual feature ofthis lesion
MALIGNANT MELANOMA
Malignant melanoma is one of the most common malignancies of the foot, and it has been reported to metastasize to the adjacent bones in the foot, perhaps by contiguous spread rather then true metastasis. In a similar fashion, subungual (under the fingernail or toenail) melanoma in the hand or the foot has been reported to spread to the adjacentBONE ISLAND
Bone island is also called solitary enostosis. The lesion is a hamartoma, consisting of normal tissue in an abnormal location. It appears as a solitary area of mature, lamellar bone located within another bone, usually within an area of cancellous bone.

Enchondroma is a solitary, benign, intramedullary cartilage tumor that is often found in the short tubular bones of the hands and feet, distal femur, and proximal humerus. The peak incidence is in the third decade and is equal between men and women. Multiple enchondromatosis is a non-heritable condition also known as Ollier's disease. METASTATIC PROSTATE CANCER The metastatic deposits of prostate cancer in the spine can cause pain but there are many effective treatments available which the oncologist can use to eliminate the pain. Prostate cancer is a relatively slow-growing type of cancer. Many men have it in their later years, but few of them actually die of it. Since it tends to effect elderlymen

BROWN TUMOR
Hyperparathyroidism results in disorders of bone and mineral metabolism. Diffuse and focal lesions may arise in multiple bones. On occasion, a patient with undiagnosed hyperparathyroidism presents with a lytic lesion that may be mistaken for a tumor. These lesions are termed "Brown Tumors" due to the presence of old hemorrhage in thelesion.

RUNNER'S BUMP
Introduction and Definition. Runners who average more than 30 miles per week occasionally develop a mass on the tibialis anterior tendon sheath that may be mistaken for a tumor. On examination, a soft, mobile lesion surrounds the tibialis anterior tendon at the level where the tendon makes impinges on the shoelaces or the tongue of theshoe.

The lesion is typically a solitary, slightly expansile,lucent lesion with minimal matrix calcification, that may thin, expand, or fracture the nearby cortex. DEDIFFERENTIATED CHONDROSARCOMA Dedifferentiated chondrosarcoma is a high-grade sarcoma that develops in a preexisting benign cartilage tumor, or in a preexisting low / intermediate grade chondrosarcoma. The tumor is a spindle cell sarcoma, most commonly osteosarcoma or malignant fibrous histiocytoma. The low grade and high grade portion are adjacent but distinct. BIZARRE PAROSTEAL OSTEOCHONDROMATOUS PROLIFERATION Bizarre parosteal osteochondromatous proliferation (BPOP) is a rare lesion that occurs most commonly in the hands and feet. This lesion grows rapidly and has aggressive features on imaging studies as well as confusion findings on histopathology, leading to many WELCOME TO BONETUMOR.ORG The webs most comprehensive source for bone tumor information.

METASTATIC KIDNEY CANCER Kidney cancer metastasis most commonly affects the spine, ribs, pelvis, and proximal long bones. Kidney cancer may metastasize extremely late after the treatment of the primary lesion, up to ten years or more. Why the tumor seems to lay dormant for so long and then suddenly pop up in the bone is not known. Another unusual feature ofthis lesion
OSTEOCHONDROMATOSIS
Description. HMOCE (hereditary multiple osteochondral exostosis) is a rare, autosomal dominant inherited disease where multiple osteochondral bone tumors occur on the surfaces of the bones. The severity of the disease can vary from mild to very disabling. A small number of the tumors may develop into low grade chondrosarcomas. FEMUR | BONETUMOR.ORG A 95 year old lady with increasing pain and swelling in her thighMALIGNANT MELANOMA
Malignant melanoma is one of the most common malignancies of the foot, and it has been reported to metastasize to the adjacent bones in the foot, perhaps by contiguous spread rather then true metastasis. In a similar fashion, subungual (under the fingernail or toenail) melanoma in the hand or the foot has been reported to spread to the adjacentENCHONDROMA
Enchondroma is a solitary, benign, intramedullary cartilage tumor that is often found in the short tubular bones of the hands and feet, distal femur, and proximal humerus. The peak incidence is in the third decade and is equal between men and women. Multiple enchondromatosis is a non-heritable condition also known as Ollier's disease. A TUMOR IN THE FIBULA DISCOVERED BY ACCIDENT. The patient is 51 and in generally good health with severe leg pain. He was cutting trees in his yard when a falling limb struck his leg. An abnormality in the left mid distal fibula was noted. A BONE TUMOR IN THE FINGER Surface lesions are a special group of tumors, and since there are only a few tumors in this group, the list of possibilities is short. A surface lesion on the phalanx of a finger or toe, especially with the xray features this one has, is a "classic" presentation of one tumorin particular.
SUBCHONDRAL CYST
Subchondral bone cyst presents as a tumor mimic due to the following scenario: A patient with a known cancer develops worsening pain in a joint. Although a plain xray would reveal the true nature of the lesion, in some cases MRI is the first imaging modality used. MRI tends to make these lesions look much more worrisome than they reallyare.

Primary lymphoma of bone is a rare tumor which comprises approximately 5 - 7% of malignant bone tumors and 5% of the extranodal non-Hodgkin’s lymphomas present as primary lymphoma of bone. However secondary bone involvement is seen about 16 – 20% of patients with lymphoma. 1. A single skeletal site, with or without regional lymphnode

BONE ISLAND
Bone island is also called solitary enostosis. The lesion is a hamartoma, consisting of normal tissue in an abnormal location. It appears as a solitary area of mature, lamellar bone located within another bone, usually within an area of cancellous bone. OSTEOMA | BONETUMOR.ORG Dr. Enneking describes the lesion as having the appearance of "one-half of a billiard ball" attached to the underlying bone. The adjacent cortex is not involved or weakened. Peripheral osteomas are radiopaque lesions with expansive borders that may be sessile or pedunculated. Osteomas need to be differentiated from enostosis whichalso appear
MULTIPLE MYELOMA
Multiple myeloma is a malignant tumor of plasma cells that causes widespread osteolytic bone damage. Multiple myeloma is the most common primary tumor of bone and is found in the spine, skull, ribs, sternum and pelvis but may affect any bone with hematopoietic red marrow.BROWN TUMOR
Hyperparathyroidism results in disorders of bone and mineral metabolism. Diffuse and focal lesions may arise in multiple bones. On occasion, a patient with undiagnosed hyperparathyroidism presents with a lytic lesion that may be mistaken for a tumor. These lesions are termed "Brown Tumors" due to the presence of old hemorrhage in thelesion.

As the risk of malignant transformation is unknown, cancer risk assessment should be performed by an orthopedic oncologist. The authors of this site pay particular attention to the large deep osteochondromas, often located on the pelvis or the spine, where malignant transformation may be more likely and much more difficult totreat.
METASTATIC KIDNEY CANCER Renal cell cancers rank as the approximately sixth most common site of origin of metastatic deposits in the skeleton. Although the number of cases of this cancer is proportionally small, the tumor has a high avidity for bone and thus creates relatively large number of bonelesions.
MALIGNANT MELANOMA
Risk factors for malignant melanoma include the accumulation of three or more of the following: blond hair, a positive family history for cancer, immunosuppressive disorders such as HIV or AIDS, freckling on the upper back, three or more blistering sunburns before age 20 or outdoor summer jobs for more than three teenage years, exposure to arsenic compounds, and multiple nevi or atypical nevi.
