Reference only, to read alongside your own examination.

Symptoms — what the patient reports (7)

  • Most are picked up by chance on an x-ray taken for something else
  • Next commonest is a painless lump felt over the affected bone [skin nodule]
  • The lump can look unsightly where bone is close to the skin, as at the upper shin or ribs
  • Pressure on a nerve gives tingling and numbness [numbness · tingling]
  • Pressure on a vessel alters skin colour, pulses or blood flow
  • A lesion sitting under a tendon causes tendon pain and irritation on movement
  • Hereditary multiple exostoses is silent in newborns; half have a visible tumour by 5 and 80% by 10

Signs — what you find (9)

  • Absent pulses or colour change downstream of the lesion
  • Arterial or venous clot, aneurysm or false aneurysm can develop
  • The knee is the usual site, catching the popliteal artery and the peroneal and posterior tibial nerves
  • Soft tissue squeezed by the lesion can raise a bursa and inflame it
  • Lesions beside the discs can produce kyphosis or spondylolisthesis; cord compression is rare
  • Multiple exostoses bring valgus deformities: ankle valgus, knock knee, coxa valga
  • Also unequal limb length, sideways deviation at the wrist, and short hand or foot bones
  • Multiple exostoses may bring hip socket dysplasia, hip impingement or juvenile arthritis
  • Dislocation or partial dislocation of hip, kneecap or talus is common in multiple exostoses

Tests (12)

  • X-ray: a surface lesion at the metaphysis whose cortex and marrow run on from the parent bone, capped by cartilage
  • Broad-based sessile or narrow-stalked pedunculated; the stalked ones point away from the joint
  • The cartilage cap does not show on plain film and shrinks once growth finishes
  • Broad-based lesions carry the higher risk of turning malignant
  • Worrying x-ray changes: the lesion grows, changes shape, shows periostitis, or its cortical edge blurs
  • Scapula, pelvis and spine lesions are often unclear on film and need further imaging
  • CT or MRI when the x-ray suggests malignant change
  • Cap thickness: 1 to 3 cm while still growing, only millimetres once mature
  • A cap over 2 cm in a fully grown patient is worrying and needs tissue sampling
  • MRI shows an overlying bursa as a well-defined bright fluid collection
  • With neurological signs, MRI may show the nerve pushed aside, swollen or bright, and its muscles swollen or fatty
  • Bone scan does not help: benign and malignant lesions both light up

If not this — what else fits (10)

  • Subungual exostosis, on the back of the end finger bone near the nail, often painful with skin ulceration
  • Subungual exostosis is also a surface lesion but has no marrow continuity, and sits elsewhere
  • Trevor disease: several lesions off the epiphysis, usually in the legs, three boys to each girl
  • Trevor disease shows up young with altered gait, bone deformity or a felt mass, and never turns malignant
  • Turret exostosis sits outside the cortex on the back of a finger bone with no marrow continuity
  • Nora lesion of the hands and feet: surface lesion, no marrow continuity, no malignant risk reported
  • Parosteal osteosarcoma: a big lobulated dense mass on the bone surface without marrow continuity
  • Parosteal osteosarcoma favours the metaphysis, most often the back of the lower femur
  • Juxtacortical chondroma scoops out the nearby cortex with periosteal reaction, typically at ages 20 to 40
  • Subperiosteal haematoma: a smooth oval surface lesion after injury, with no marrow continuity

NO DRUG THERAPY IN PRIMARY CARE (RECOGNITION & REFERRAL)

1st line
Adult dose and duration

Benign growths such as osteochondroma usually just need monitoring; the GP recognises the mass and refers to orthopaedics only if it is symptomatic or the diagnosis is uncertain. - Refer

Paediatric dose

Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

Dose source

No dose - referral pathway, no medicine given in primary care

Why

Benign growths such as osteochondroma usually just need monitoring; the GP recognises the mass and refers to orthopaedics only if it is symptomatic or the diagnosis is uncertain.

Cautions
  • Rapid growth, new pain, features suggesting malignant change, nerve or vessel compression.
  • No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
