[edit] Discussion of Osteopoikilosis

  • Osteopoikilosis is AKA osteopathia condensans disseminata and "spotted bone disease"
  • Osteopoikilosis is an asymptomatic disorder
  • Characterized by an abnormality in the enchondral bone maturation process that results in numerous round 2-10 mm bone islands, that are symmetrically distributed within the metaphyses and epiphyses of the long bones,
  • Lesions appears in childhood and persists throughout life.


  • It may either be inherited in an autosomal dominant fashion or occur sporadically.
  • Men and Women are equally affected.
  • Sites of predilection include hands, feet, pelvis, and femur.
  • The ribs, skull and vertebrae are typically spared.


  • Some patients have connective tissue nevi called dermatofibrosis lenticularis disseminata.
  • Osteopoikilosis have also been found to be associated with a tendency to keloid formation, dwarfism, spinal stenosis, dystocia, melorheostosis, tuberous sclerosis and scleroderma.


  • Its major clinical significance is that it should not be confused with metastatic osteoblastic lesions.
