Differential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. of the arm). Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkin's lymphoma.
In the group of malignant small round cell tumors that includes Ewing sarcoma, bone lymphoma, and small cell osteosarcoma, the cortex may appear almost normal radiographically, while permeative growth occurs throughout the Haversian channels. These tumors may be accompanied by a large soft-tissue mass while almost no bone destruction is visible.
The supraclavicular fossa is an indentation (fossa) immediately above the clavicle. In terminologia anatomica, it is divided into fossa supraclavicularis major and fossa supraclavicularis minor. Fullness in the supraclavicular fossa can be a sign of upper extremity deep venous thrombosis.
Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. [1] [2] There may be no symptoms, [3] or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture. [4] Diagnosis is by X-ray, CT scan and sometimes MRI. [4] Most occur as a less than three centimetre size ...
The lesion may arise de novo or may arise secondarily within a pre-existing bone tumor, because the abnormal bone causes changes in hemodynamics. An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause ...
Plasmacytoma is a plasma cell dyscrasia in which a plasma cell tumour grows within soft tissue or within the axial skeleton.. The International Myeloma Working Group lists three types: solitary plasmacytoma of bone (SPB); extramedullary plasmacytoma (EP), and multiple plasmacytomas that are either primary or recurrent. [1]
Gorham's disease (pronounced GOR-amz), also known as Gorham vanishing bone disease and phantom bone disease, [1] is a very rare skeletal condition of unknown cause.It is characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis.
Osteochondroma is the most common benign tumor of bone. [1] [2] The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones . [3] [4] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone. Tumors most commonly affect long bones around the knee and in the forearm.
