occur as multiple nodules of synovial chondromatosis within a joint, as a solitary lesion within or adjacent to joint, or as an isolated cartilagenous lesion in the soft tissues, mostly of the hands and feet.
multiple endocrine neoplasia type 2, neurofibromatosis type 1, von Hippel Lindau syndrome, or succinate dehydrogenase mutations); a family history of PCC; an incidentally discovered adrenal mass; pressor response to anesthesia, surgery, or angiography; onset of hypertension at a young age (<20 years); idiopathic dilated cardiomyopathy; and a history of gastrointestinal stromal tumors or pulmonary chondromas
Soft tissue chondromas
are benign tumours that arise commonly in the hands and feet of adults, but rarely in other locations.
are rare, benign, cartilaginous tumors that constitute about .
Benign neoplasms were given names such as lipoma, chondromas
, and myomas, according to their histological derivation--from fat, cartilage, and muscle, respectively.
are slowly growing asymptomatic tumors that are usually discovered incidentally.
However, the differential diagnosis for lesions with this appearance is wide and includes: sebaceous cysts, ossifying hematomas, giant-cell tumors, chondromas
, dermoid cysts, foreign body reactions, degenerating fibroxanthomas, metastatic bone formations and osteoma cutis.
3) The differential diagnosis of submucosal lesions of the larynx includes adenomas, chondromas
, laryngoceles, and lipomas.
are benign tumors of hyaline cartilage that may arise from the medullary cavity or the surface of the bone.
The rapid decrease in dose at the end of the proton beam makes proton therapy a good option for skull base chondromas
The reported rate of histologic uncertainty between low-grade chondrosarcomas and benign chondromas
Among the benign tumors are calcified nasal polyps, ossifying fibromas, osteomas, chondromas
, odontomas, calcifying angiofibromas, nasal gliomas, and septal desmoid tumors; malignant tumors include osteosarcomas, chondrosarcomas, and squamous cell carcinomas.
