Efficacy of hemoporfin photodynamic therapy for pulsed dye laser-resistant facial port-wine stains in 107 children: A retrospective study

Background: Port-wine stains occur in 0.3–0.5% newborns, mainly on the face and neck. Pulsed dye laser is recognized as the gold standard treatment; nevertheless, it is associated with a low cure rate and a high recurrence rate. Aims: This study aims to evaluate the efficacy of hemoporfin photodynamic therapy for pulsed dye laser-resistant port-wine stains in children. Methods: We studied 107 children who received hemoporfin photodynamic therapy for port-wine stains on the face and neck that were resistant to pulsed dye laser. After intravenous injection of 5 mg/kg hemoporfin, the local lesion was irradiated with 532 nm LED green light for 20 min with a power density of 80–100 mW/cm2. A total of 65 patients were given a second treatment after eight weeks. The efficacy and therapeutic responses were recorded at four days and eight weeks after each treatment. Results: The efficacy was positively correlated with the number of treatments received; two treatment sessions yielded significantly better results compared to a single treatment with a response rate of 96.9%, a significant response rate of 50.8% and a cure rate of 21.5%, respectively (P < 0.001). After two treatment sessions, the efficacy was negatively correlated with age (P = 0.04). The efficacy for port-wine stains located on the lateral part was better than that of the central face (P = 0.04). The efficacy for the pink type was better than that for the red and purple types (P = 0.03). No allergic or systematic adverse reactions were reported. Limitations: No objective measurement data were available. Conclusion: Hemoporfin photodynamic therapy is effective and safe for pulsed dye laser-resistant facial port-wine stains in children.

A neonate with Klippel–Trénaunay syndrome: a case report

Background Klippel–Trénaunay syndrome is a rare congenital capillary–lymphatic–venous condition characterized by the clinical triad of capillary malformations (port wine stains), varicose veins with or without venous malformations, and bony and/or soft-tissue hypertrophy. It has a very low incidence of about 1:100,000. Case presentation We report the case of 21-day-old neonate Black African female (born in Uganda) with Klippel–Trénaunay syndrome who presented with macrodactyly and ectrodactyly on the left foot, as well as numerous port wine stains on the left thoracoabdominal region and anteroposterior left lower limb. Color Doppler ultrasound examination of the left lower limb and abdomen revealed varicose veins without signs of arteriovenous fistula. Conclusion The report presents the case of a neonate with a rare congenital vascular disorder type Klippel–Trénaunay syndrome.

Klippel–Trénaunay Syndrome and Developmental Coxa Vara in the Same Limb: A Case Report with a Review of the Literature

We present a case of a 14-year-old girl who was first treated when she was 4 years old. She had progressive limping of the left lower limb from the age of 3 years. She was diagnosed to have developmental coxa vara of the left hip and treated by a subtrochanteric valgus osteotomy of the left femur. Later, she developed hypertrophy of the left upper and lower limbs. There were port-wine stains over the left lower limbs with multiple superficial varicosities. Her diagnosis was Klippel–Trénaunay syndrome (KTS). She is asymptomatic at the final follow-up. Both developmental coxa vara and KTS are rare conditions. We present this case to demonstrate the rarest combination of two rare conditions occurring in the same limb.
