HistoryThis section has been translated automatically.

Ferreira-Marques 1953; Gschwandtner/ Münzberger 1974

DefinitionThis section has been translated automatically.

Recoverable ligamentous atrophy of the fatty tissue on the outside of the thighs in young women.

EtiopathogenesisThis section has been translated automatically.

The exact causes have not yet been conclusively investigated. Chronic, repetitive, external traumatisation (e.g. regular propping up or leaning on table edges with the thighs) as well as local circulatory disturbances are discussed. Etiologically related is the so-called bra strap lipatrophy.

ManifestationThis section has been translated automatically.

Occurs mainly among younger women and middle-aged women.

LocalizationThis section has been translated automatically.

Thigh extensor side, upper and lower extremity. Also in the area of the shoulders under the bra straps.

Clinical featuresThis section has been translated automatically.

Symmetrical, mostly semicircular and horizontal, painless, ligamentous skin depression without signs of inflammation or other subjective symptoms, with unchanged epidermis and lack of induration.

HistologyThis section has been translated automatically.

No pathological findings.

Differential diagnosisThis section has been translated automatically.

  • Circumscript scleroderma: pale skin color, extensive induration, lilac ring; histological clarification with inflammatory infiltrates.
  • Localized involutional lipoatrophy: mostly unilateral, rarely multilocular; skin atrophy (glucocorticoids, insulin) often superimposed in the area of injection sites.
  • Anular lipoatrophy: possibly identical clinical picture.

TherapyThis section has been translated automatically.

If any permanent traumatisation is avoided, spontaneous regression occurs after months to years. Local therapy is not necessary.

Progression/forecastThis section has been translated automatically.

Favourable, mostly spontaneous regression, especially when the triggering trauma is avoided.

Case report(s)This section has been translated automatically.

The 49-year-old, obese saleswoman reported of an 8-month-old ("suddenly appeared") completely symptom-free, ligamentous depression on the extensor sides of both thighs. Trauma was not remembered, neither were injections in this area.

Findings: On both OS (at a height of about 80 cm), on the extensor side, a 3.5 cm wide, skin-coloured, semicircular, band-shaped indentation about 14 cm long, completely without irritation, without any induration. No change of the skin surface.

Histology: Normal fatty tissue without signs of inflammation.

Evaluation and course: By exact questioning it could be determined that the patient as a saleswoman, by forward rocking movement, induced a recurrent frontal traumatisation of the thighs. The resulting horizontal trauma pattern of the thighs was congruent to the edge of the counter. After this mechanism was uncovered and avoided, the surface depression "healed" completely within 8 months.
