Siliconomas of the lower limb: Tumour-like excision and reconstruction

Silicone oil injection can cause several complications including pain, cellulitis, abscesses, skin compromise, migration, embolism and multiorgan failure. Oil-infested tissue excision remains the solely treatment to prevent such complications.

The authors evaluate tumor-like excision of the oil-infested tissue as a treatment for patients experiencing silicone injections in the lower limbs, to both preserve aesthetic appearance and solve further risk of complication from silicone.

Between January 2004 and January 2011 a total of 12 consecutive, nonrandomized female patients underwent surgical management of siliconoma of the lower limb. The mean age was 41-years, range from 22 to 61 years and all patients didn't referred comorbidities. Eight siliconomas were located on the leg and 4 were on the thigh. The mean area of siliconoma was 35 cm², range from 25 to 60 cm². Each patient was evaluated by ultrasonography and EchocolorDoppler of the soft tissue and in order to achieve a "staging" of siliconoma.

Healing was uneventful in all cases. Three patients (25%) suffering hypertrophic scarring underwent further injection of corticosteroids to improve hypertrophic scars quality. Two patients (16.6%) required a further session of structural fat grafting to improve thigh's profile. All patients were satisfied with the cosmetic results and indispositions requiring medical therapy disappeared.

Tumor-like excision and immediate reconstruction appears to be a safe and consistent surgical option that preserves aesthetic appearance for patients victims of illegal oil silicone injection of the lower limbs.
