Endochrmatosis

Radiograph showing distal radius enchondromas in a 7-year-old girl with Ollier's disease

The term enchondromatosis refers to multiple enchondromas (islands of cartilaginous tissue in the metaphyses of tubular bones) that retard growth and deform the bone.

Ollier's disease (Lous Léopold Ollier (1830-1900), French surgeon) - affecting ½ of the body

Maffucci syndrome (Angelo Maffuccini (1847-1903), Italian pathologist) - enchodromatosis + multiple hemangiomas (i.e. hemangiomatosis)

Clinical picture

  • affected long bones shortened and bent, enlarged metaphyses
  • fingers enlarged and deformed in the hands, pseudomadelung's deformity on the forearm (see Madelung's deformity), genu valgum

X-ray image

  • puffy lucencies, calcified stripes running from the metaphysis to the diaphysis

Therapy

  • removal of symptomatic enchondromas, spongioplasty
  • corrective osteotomy and bone lengthening
  • dispensation (risk of malignancy)
