Extensive cervical-mediastinal cystic lymphatic malformation treated with sclerotherapy in a child with Klippel-Trenaunay syndrome

Overgrowth syndrome in neonates: a rare case series with a review of the literature

We present here two-term neonates presenting with right lower limb hypertrophy, a port-wine stain, acral abnormalities and clubfeet. These neonates had overlapping features of Klippel Trenaunay syndrome and congenital lipomatous overgrowth, vascular malformation, epidermal nevi and scoliosis/skeletal abnormalities. Such overgrowth syndrome has not been previously described in the literature. Both the neonates are doing well and are under regular follow-up.

Sclerotherapy with bleomycin versus surgical excision for extracervical cystic lymphatic malformations in children

PURPOSE

Sclerotherapy (ST) with bleomycin is an effective treatment for cervical cystic lymphatic malformations (LM) in children. However, its efficacy for treating extracervical cystic LM in children has not been investigated adequately. This retrospective study compares the efficacy of ST with surgery for treating extracervical cystic LM in children.

METHODS

The subjects of this study were children treated for extracervical cystic LM at our hospital between 1970 and 2013. We evaluated retrospectively the hospital records of these children for age, gender, presenting symptoms, location of the lesion, radiological findings, treatments, complications, duration of hospitalization, and outcome.

RESULTS

We analyzed the records of 70 children (M:F = 1:9) with a mean age of 52.57 ± 54.87 months (range 1-204 months). The number of children treated by surgery alone, ST alone, and surgery plus ST was 53 (77 %), 13 (18 %), and 4 (5 %), respectively. Surgery comprised total excision (n = 41), near-total excision (n = 9), partial excision (n = 6), and incisional biopsy (n = 1). The complication and recurrence rates were lower, the complete response rate was higher, and the length of hospitalization was shorter in the ST group than in the surgery group (5 vs. 15 % and 8 vs. 17 %, respectively, p < 0.05; 91 vs. 77 %, respectively, p = 0.05; and 2.42 ± 1.67 vs. 13.57 ± 16.24 days, respectively, p = 0.03).

CONCLUSION

ST is as safe as surgery for extracervical macrocystic or mixed LMs in children, but is much more effective with higher success rates and lower recurrence rates. Thus, ST provides a cost-effective and appropriate mode of treatment for children with extracervical cystic LM.

An interesting fistula tract presenting with recurrent gluteal abscess: instructive case

A fistula extending from the gluteus to penis is an extremely rare entity. In this paper, we have highlighted novel variant of congenital penile to gluteal fistula complicated with gluteal and penoscrotal abscess in a previously healthy boy. A fistulous tract extending from the gluteus to penis has been shown by fistulogram. Bleomycin has been used in fistula tract with successful results in our patient.

A Step-by-Step Practical Approach to Imaging Diagnosis and Interventional Radiologic Therapy in Vascular Malformations

Within vascular anomalies, vascular malformations are those present at birth that grow with the patient and exhibit abnormal dilated vascular channels lined by mature endothelium. Vascular tumors, the other group of vascular anomalies, demonstrate endothelial hypercellularity. Vascular malformations are further divided into low-flow varieties (capillary, venous, and lymphatic malformations) and high-flow varieties (arteriovenous malformation and fistula). All malformations exhibit a predictable group of clinical patterns that vary in severity and rate of progression. The interventional radiologist must incorporate this clinical data with characteristic ultrasound and magnetic resonance findings to arrive at a diagnosis. One must then decide in a multidisciplinary fashion, based on objective clinical criteria and image-based morphology, if the patent is a candidate for intervention. Sclerotherapy is a technique used to treat vascular malformations whereby an endothelial-cidal agent is introduced into the endoluminal compartment to initiate vascular closure. The high flow rate of an arteriovenous malformation requires the incorporation of superselective transarterial, direct, and transvenous access with flow reduction techniques to deliver adequate dose of sclerosant and embolic to the nidus. Satisfactory outcomes are seen in over half of all malformations patients. Similar treatment-related complications are seen between malformations but are lowest in lymphatic and highest in arteriovenous malformations.

Hemihyperplasia-multiple lipomatosis syndrome: an underdiagnosed entity in children with asymmetric overgrowth

Hemihyperplasia can be found as an isolated abnormality, or as a predominant associated feature of an asymmetric overgrowth syndrome. This report describes 2 patients with hemihyperplasia-multiple lipomatosis syndrome. The finding of hemihyperplasia prompts careful examination for associated lipomatous lesions. Close follow-up is required because progressive growth of lipomatous lesions can be encountered as well as recurrence after excision.
