Severe wrist contracture in a child with linear scleroderma

Challenges and complications in juvenile localized scleroderma: A practical approach

Juvenile localized scleroderma is characterised by inflammation which drives fibrosis in skin and soft tissues. The more severe subtypes of localized scleroderma such as linear and craniofacial are more common in children. Additionally, extracutaneous involvement is seen in half of all children and is associated with poorer treatment outcomes and health-related quality of life. Evidence for the management of craniofacial and extracutaneous involvement is lacking and therefore poses a challenge to clinicians. This review aims to provide a practical approach to management of these most challenging features of juvenile localized scleroderma through case studies where we present the available evidence, current recommendations and considerations for management.

Flap Reconstruction for Treatment of Pediatric Linear Scleroderma

BACKGROUND

Linear scleroderma is a rare connective tissue disease characterized by thickening of the skin due to excess collagen deposit. It is the most frequent type of localized scleroderma in the pediatric population (40%-70%), and it usually affects the extremities and head. Linear scleroderma can cause growth disturbances, extremity length discrepancy, and debilitating joint contractures. The aim of this study was to describe the surgical outcomes of microsurgical flap reconstruction of linear scleroderma in the pediatric population.

METHODS

A retrospective review of all children with linear scleroderma was performed at our institution. Patients less than 18 years of age with clinical diagnosis of linear scleroderma and who underwent microsurgical flap reconstruction for correction of their scleroderma were included. Fat grafting procedures were excluded. Patient demographics and surgical outcomes were collected.

RESULTS

A total 7 patients underwent microsurgical flap reconstruction for treatment of their linear scleroderma producing debilitating soft tissue contractures and preventing ambulation or elbow extension. Six patients had scleroderma involving the lower extremity and 1 involving the upper extremity. Three anterolateral thigh and 4 latissimus dorsi flaps were performed. The median age at surgery was 7 years (Q1-Q3, 5-11), and the median body mass index was 21.3 kg/m2 (Q1-Q3, 16.5-22.1). The median follow-up was 121.1 months (Q1-Q3, 43.2-187.4). All flaps survived, and no donor site complications were reported. Perioperative complications included wound infection that required debridement (n = 1), immediate postoperative bleeding requiring surgical intervention (n = 1), intraoperative venous congestion (n = 1), and scleroderma recurrence outside the flap (n = 2). When comparing anterolateral thigh and latissimus dorsi flaps, there was no statistically significant difference in the development of surgical complications, number of surgical revisions per patient [median, 4 (Q1-Q3, 4-7) vs 2.5 (Q1-Q3, 1.3, 3), P = 0.0916], or unplanned surgical interventions [median, 0 (Q1-Q3, 0-1) vs 1 (Q1-Q3, 0-1), P = 0.7228]. The reconstruction was successful in improving range of motion in 6 patients, 5 of which reached full weight-bearing. However, all patients had residual limb deformity, and 4 had remaining extremity length discrepancy.

CONCLUSIONS

Microsurgical flaps are a good option for functional improvement of severe pediatric linear scleroderma affecting the extremities. However, residual limb deformity is common, and patients are often required to undergo additional surgical revisions.

A surgical approach for stable lesions of linear scleroderma

A 29-year-old Japanese woman presented with alopecia lesions in her occipital region and was diagnosed as linear scleroderma. Topical steroids along with psoralen and UVA light therapy were applied, but the lesion persisted. A surgical approach was therefore selected to treat the lesion. The resection was successful without any recurrence for 1 year. Sclerotic lesions on the exposed areas can cause cosmetic disfigurement, and surgery may be a useful modality for treating stable linear scleroderma.

Case of localized scleroderma successfully treated with bath psoralen and ultraviolet A therapy

The patient was a 12-year-old girl with linear scleroderma distributed on the right abdomen, dorsal aspect of the right thigh, lower leg and foot. The initial regimen of oral prednisolone and methotrexate, or i.v. methylprednisolone failed in the treatment of the scleroderma. Then bath psoralen and ultraviolet A therapy (bath-PUVA) therapy of 0.2 J-4.0 J/cm(2) daily to total doses 62.8 J/cm(2) combined with oral prednisolone was started. After bath-PUVA therapy, regression of the skin sclerosis was observed, the possible mobile range of the right ankle was increased and histological examination confirmed improvement of the sclerosis. The successful results of bath-PUVA therapy in this case suggest its utility for localized scleroderma.

Treatment of 'en coup de sabre' Deformity with Porous Polyethylene Implant

Linear scleroderma "en coup de saber" (LSCS) deformity is a subgroup of scleroderma characterized by unilateral atrophy and depression above the level of the eyebrow. In rare cases where it involves the whole unilateral face it can be mistaken with Parry-Romberg syndrome. Involvement of the trunk and extremities together with facial lesions has been extremely rare in the literature. We report an unusual case of linear scleroderma "en coup de sabre" where there is concomitant involvement of the ipsilateral side of the trunk and lower extremity. The patient's facial deformity is reconstructed with a polyethylene implant.
