DefinitionThis section has been translated automatically.

In the sacrum localized congenital malformation of the corial connective tissue. Either isolated or occurring as a partial symptom of Pringle-Bourneville phacomatosis or Buschke-Ollendorf syndrome. No malignancy development.

ClassificationThis section has been translated automatically.

  • Solitary collagen nevus (mostly spontaneous occurrence)
  • Large-nodular disseminated connective tissue nevus (familial occurrence-predominantly located on the trunk)
  • Multiple connective tissue nevi (Familial cutaneous collagenoma; OMIM 115250)

LocalizationThis section has been translated automatically.

The solitary form is almost exclusively located in the lumbosacral region. In principle, however, every bodily cell can be affected.

Clinical featuresThis section has been translated automatically.

Multiple, skin-coloured or whitish, symptomless, grouped standing or confluent to larger plaques (cobblestone-like aspect), flat raised nodules, plaques or knots of 0.2-5.0 cm in diameter.

HistologyThis section has been translated automatically.

Increased, densely packed collagenous connective tissue with clumpy collagen fibres. Reduced and altered elastic fibre texture, sometimes intertwined like a band. The changes are usually discreet and can only be assessed in comparison to the normal dermis.

DiagnosisThis section has been translated automatically.

The clinical picture in typical localization is diagnostic.

Differential diagnosisThis section has been translated automatically.

Connective tissue nevi of different genesis.

TherapyThis section has been translated automatically.

No therapy necessary. Excision if necessary.
