MULTIPLE OSTEOCHONDROMAS

Alternate names

MULTIPLE OSTEOCHONDROMAS Is also known as multiple cartilaginous exostoses, bessel-hagen disease

Description

Multiple osteochondromas (MO) is characterised by development of two or more cartilage capped bony outgrowths (osteochondromas) of the long bones.

Most common symptoms of MULTIPLE OSTEOCHONDROMAS

  • Short stature
  • Scoliosis
  • Neoplasm
  • Failure to thrive
  • Muscle weakness

EXOSTOSES, MULTIPLE, TYPE I

Alternate names

EXOSTOSES, MULTIPLE, TYPE I Is also known as multiple cartilaginous exostoses, ext1, multiple osteochondromas, diaphyseal aclasis, ext, osteochondromatosis

Description

Multiple hereditary exostoses (EXT) is an autosomal dominant disorder characterized by multiple projections of bone capped by cartilage, most numerous in the metaphyses of long bones, but also occurring on the diaphyses of long bones. Flat bones, vertebrae, and the ribs may also be affected, but the skull is usually not involved. Deformity of the legs, forearms (resembling Madelung deformity), and hands is frequent (Peterson, 1989).Two conditions in which multiple exostoses occur are metachondromatosis (OMIM ) and the Langer-Giedion syndrome (LGS ); the latter condition is also known as trichorhinophalangeal syndrome type II. Furthermore, exostosis-like lesions occur with fibrodysplasia ossificans progressiva (FOP ), occipital horn syndrome (OMIM ), and the adult stage of hereditary hypophosphatemia (see {307800}); these exostoses are located at sites of tendon and muscle attachment. A relatively rare variant of the supracondylar process, on the anteromedial surface of the distal humerus, can be confused with an exostosis; the variant is said to be present in about 1% of persons of European descent (Silverman, 1985).

Most common symptoms of EXOSTOSES, MULTIPLE, TYPE I

  • Short stature
  • Neoplasm
  • Depressivity
  • Abnormality of the foot
  • Genu valgum

TRICHORHINOPHALANGEAL SYNDROME TYPE 2

Alternate names

TRICHORHINOPHALANGEAL SYNDROME TYPE 2 Is also known as langer-giedion syndrome, deletion 8q24.1, chromosome 8q24.1 deletion syndrome, lgs, monosomy 8q24.1

Description

Langer-Giedon syndrome, also known as trichorhinophalangeal syndrome type 2, is a very rare, genetic, multiple congenital anomaly disorder characterized by bone abnormalities, distinctive facial features, multiple exostoses, and intellectual disability.

Most common symptoms of TRICHORHINOPHALANGEAL SYNDROME TYPE 2

  • Intellectual disability
  • Seizures
  • Short stature
  • Generalized hypotonia
  • Hearing impairment

CHONDROSARCOMA

Description

Chondrosarcoma is a malignant bone tumor arising from cartilaginous tissue, most frequently occuring at the ends of the femur and tibia, the proximal end of the humerus and the pelvis; and presenting with a palpable mass and progressive pain. Chondrosarcoma is usually slow growing at low histological grades and can be well managed by intralesional curettage or en-block wide resection.

Most common symptoms of CHONDROSARCOMA

  • Abnormality of the skeletal system
  • Chondrosarcoma
