Term | Definition |
osteogenesis imperfecta (brittle bone disease) | abnormal development of type I collagen; blue sclera and opalescent teeth |
achondroplasia | impaired maturation of cartilage in growth plate; major cause of dwarfism |
osteopetrosis (marble bone disease) | deficient osteoclast activity so defective bone remodeling and pancytopenia |
osteoporosis | increased porosity of skeleton from reduced bone mass so fragile; related to reduced estrogens |
Paget disease (osteitis deformans) | bursts of osteoclast resorption, osteoblast deposition and cellular exhaustion; net effect is a gain in bone mass but new bone is weak -possibly due to a paramyxovirus |
monostotic | Paget disease bone lesion confined to a single bone |
polyostotic | Paget disease bone lesion in numerous bones |
mosaic pattern | histological feature of Paget disease, loose interstitium that is very vascular |
cotton-wool pattern | radiographic pattern of Paget disease, radiolucent and radiopaque areas |
osteomyelitis | infection that spreads to medullary spaces of bone, often Staphylococcus aureus |
acute suppurative osteomyelitis | type of osteomyelitis, treat by draining and giving antibiotics |
chronic suppurative osteomyelitis | type of osteomyelitis, infection causing fibrosing reaction so treat by surgery and antibiotics |
fibrous dysplasia | replacement of localized bone by proliferation of fibrous tissue and unorganized woven bone |
monostotic fibrous dysplasia | involves single bone, begins in childhood and stops at puberty |
polyostotic fibrous dysplasia without endocrine involvement (Jaffe syndrome) | multiple, unilateral bones affected;some cafe-au-lait pigmentation |
polyostotic fibrous dysplasia in association with endocrinopathies (McCune-Albright syndrome) | melanin pigmentation of skin (cafe-au-lait), majority of bones affected unilaterally and hormone issues |
Chinese characters | appearance of histological pattern in fibrous dysplasia; fibrous CT with intermixed woven bone |
ground glass | radiographic appearance of ill-defined increased radiopacity |
Ewing sarcoma and primitive neuroectodermal tumors (PNETs) | primary malignant small round cell tumors of bone and soft tissue; patients 10-15, arise in medullary cavity and produce expansile mass with onion-skin pattern |
giant cell tumor (osteoclastoma) | neoplasm of osteoclast-like giant cells with intermixed mononuclear mesodermal cells; most arise in epiphysis of long bones and cause local pain |
metastatic disease | most common malignancies in bone from prostate, breast, kidney, and lung cancers; prostate metastasis can be radiopaque |
osteoarthritis (degenerative joint disease) | most common joint disorder; degeneration of articular cartilage with bone changes occurring as a secondary effect, does not begin with inflammation but causes it |
fibrillation | vertical fissures in cartilage cap in early stages of osteoarthritis |
eburnation | when entire bone becomes exposed and is thick and polished |
osteophytes | small bony outgrowths that cause more inflammation |
Heberden nodes | nodular enlargement, especially in fingers of osteophytes in osteoarthritis |
rheumatoid arthritis | systemic, chronic autoimmune disease that attacks the joints |
pannus | inflammatory hyperplasia of synovial membrane; eventually fills the entire joint space |
rheumatoid nodules | subcutaneous nodules in areas of mechanical pressure; necrotic collagen surrounded by granulomatous inflammation |
rheumatoid factor | autoantibodies that attach to host's own IgG antibodies |
gout | tissue accumulation of excessive amounts of uric acid that crystallizes |
primary (idiopathic) gout | gout of unknown cause or an inborn metabolic issue |
secondary gout | cause is known or gout is not the main disorder; often in chemo patients and renal failure |
acute arthritis | precipitation of urate crystals in synovial fluid and membranes; in big toe and cooler joints |
chronic arthritis | secondary to repeated acute attacks; crystals penetrate the bone and tissue and persist |
tophus | deposit of urate crystals, diagnostic of gout |
intercritical gout | asymptomatic period in between attacks |
myasthenia gravis | autoimmune disease of depletion of acetylcholine receptors; weakness, fatigue of muscles and thymic issues |
ptosis | dropping of eyelids in myasthenia gravis |
diplopia | double vision in myasthenia gravis |
Duchenne muscular dystrophy | X-linked recessive disorder, absence of dystrophin (holds myocyte together) |
pseudohypertrophy | replacement of lost muscle cells with fibrofatty tissue |
fibrous tissue tumor | fibromatosis, fibrous histiocytoma -fibrosarcoma |
adipose tissue tumor | lipoma -liposarcoma |
striated muscle tumor | rhabdomyoma -rhabdomyosarcoma |
smooth muscle tumor | leiomyoma -leiomyosarcoma |
peripheral nerve tumor | neurofibroma, neurilemoma -neurofibrosarcoma |
blood vessel tumor | hemangioma -angiosarcoma |
lymphatic vessel tumor | lymphangioma -lymphangiosarcoma |
bone forming cell tumor | osteoma, osteoblastoma -osteosarcoma |
cartilage tumor | chrondroma -chondrosarcoma |
interstitial tumor | fibromatosis-fibrosarcoma hemangioma-angiosarcoma neurofibroma-neurosarcoma |
