RESUMO
BACKGROUND/OBJECTIVES: We sought to describe the experience among members of the Hemangioma Investigator Group with pulsed dye laser (PDL) in the treatment of nonulcerated infantile hemangioma (IH) in pediatric patients in the pre- and post-beta-blocker era. METHODS: A multicenter retrospective cohort study was conducted in patients with nonulcerated IH treated with laser therapy. Patient demographics, IH characteristics, indications for/timing of laser therapy, as well as laser parameters were collected. Responses to laser therapy were evaluated using a visual analog scale (VAS). RESULTS: One hundred and seventeen patients with IH were treated with PDL. 18/117 (15.4%) had early intervention (defined as <12 months of life), and 99/117 (84.6%) had late intervention (≥12 months of life). In the late intervention group, 73.7% (73/99) had additional medical management of their IH. The mean age at PDL initiation for the late intervention group was 46.7 ± 35.3 months of life (range 12-172 months) with total number of treatments to maximal clearing of 4.2 ± 2.8 (range 1-17). Those who received propranolol prior to PDL received fewer sessions (1.1 fewer sessions, approaching significance [p = .056]). On the VAS, there was a mean 85% overall improvement compared to baseline (range 18%-100%), with most improvement noted in erythema and/or telangiectasias. The incidence of adverse effects was 6/99 (6.1%). CONCLUSIONS: PDL is a useful tool in the treatment of IH, with notable improvement of telangiectasia and erythema and low risk of complications. PDL is often introduced after the maximal proliferative phase.

INTRODUCTION: We report about a large retinal capillary hemangioma (RCH) with exudative retinal detachment and a macular fold, treated with Ruthenium-106 brachytherapy (Ru-106 BT) and scleral buckling surgery, followed by pars plana vitrectomy (PPV), for the removal of macular tractions. CASE DESCRIPTION: A 17-year-old boy was referred to our Ocular Oncology Unit for a large RCH in the left eye. BCVA was hand motion. The RCH measured 4.9 × 6.85 mm in basal diameters and 4.0 mm in thickness and was located in the mid-peripheral temporal retina. It was surrounded by extensive subretinal exudation, forming an exudative retinal detachment, with a retinal fold that extended from the lesion to the optic disc. We performed Ru-106 BT and at the moment of the plaque removal we placed a radial buckle with the aim to unbend the retinal fold. At 3-months follow-up the exudation decreased, we achieved the opening of the peripheral side of the retinal fold, but the macula was still detached. We decided to perform a lens sparing PPV, macular peeling and air tamponade, to remove the vitreoretinal tractions ab interno and to try to complete the opening of the macular fold. After 1-month BCVA was counting fingers, the retina appeared attached, also in the macular area, but the retinal fold remained partially close in the macular side. After 6 months the tumor was inactivated, the macula remained attached, unfortunately, the macular fold remained partially close. CONCLUSION: Ru-106 BT and scleral buckling concurrent approach can be an effective treatment modality in selected cases of large RCHs, followed by PPV to remove eventual vitreo-retinal tractions.

BACKGROUND: The 595-nm pulsed dye laser (PDL) has been used to treat vascular anomalies for about 30 years; however, there are insufficient data in Chinese patients concerning therapeutic efficacy, optimized parameters, and procedure techniques. OBJECTIVE: To study the efficacy and relevant factors in PDL therapy for vascular anomalies in Chinese patients. METHOD: We enrolled 431 patients with 8 different vascular anomalies and no previous treatment in this retrospective study. A detailed classification of vascular anomalies and various parameters and techniques of PDL were studied. The clinical outcomes were analysed using the Investigator Global Assessment. RESULTS: Improvements were significantly correlated with infantile haemangioma (IH) subtypes (p < 0.05). A significant correlation between efficacy and lesion colour, anatomical sites, and hypertrophic-type port-wine stain (PWS) was found (p < 0.05). There was no significant correlation between efficacy and age or sex (p > 0.05). CONCLUSION: PDL is an effective and safe therapeutic modality for managing vascular anomalies in Chinese patients. We determined that differentiating and identifying IH subtypes prior to treatment could be a useful parameter for predicting therapeutic results. Lesion colour, sites, and hypertrophic changes in PWS are relevant therapeutic factors. PDL parameters and techniques differ according to the various vascular anomalies to achieve optimal results.

OBJECTIVE: This study aimed to evaluate the clinical characteristics of infantile hemangiomas (IHs) and the safety and efficacy of the long-pulse 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser for definitive treatment of IHs in 794 Chinese patients. METHODS: Infants with hemangiomas who had received long-pulse 1,064-nm Nd:YAG laser treatment in our department in the last 5 years were recruited. Demographic and clinical characteristics were recorded and outcomes of long-pulse 1,064-nm Nd:YAG laser treatment were assessed. Statistical analyses were performed to identify factors that affected the efficacy of treatment. RESULTS: The efficacy of long-pulse 1,064-nm Nd:YAG laser for the treatment of IHs in all patients in our study was 87.57%. Efficacy did not depend on sex or the location of the lesion. Older age and superficial hemangioma were the primary factors contributing to greater efficacy of long-pulse 1,064-nm Nd:YAG laser treatment for IHs. The most common side effects were pigment changes, skin atrophy, and wrinkled redundant skin, which usually resolved spontaneously within 1 to 3 years. CONCLUSIONS: Long-pulse 1,064-nm Nd:YAG laser is a safe and efficacious treatment for IHs.

PURPOSE: To evaluate the potential benefit and risk of proton beam therapy in the treatment of symptomatic retinal papillary capillary hemangioma. DESIGN: Retrospective interventional case series. METHODS: This study included patients presenting with symptomatic exudative retinal papillary capillary hemangioma with or without association with von Hippel-Lindau disease. All patients were treated either as a first or a secondary treatment option by proton beam therapy between 2001 and 2009. The minimum follow-up was 30 months. RESULTS: Eight eyes of 8 patients (3 male and 5 female, with a mean age of 36 years [range 22-80 years]) were treated for symptomatic papillary retinal hemangioma. The median interval between onset of macular edema and proton beam therapy was 1.7 months (range 0.5-3.3 months). The median follow-up period was 84 months (range 32-106 months) between proton beam treatment and last follow-up. Exudation completely resolved in all but 1 patient after 4.2 months on average (range 2.8-7.2 months). Mean visual acuity prior to proton beam irradiation was 0.7 logMAR (0.2 DIN (DIN 58220 norm)) (range 2-0.3 logMAR) and declined to 0.8 logMAR (0.16 DIN; range 2-0.1 logMAR) at last follow-up examination (no statistical significance, P=.071). CONCLUSION: The anatomic outcome after proton beam therapy for retinal papillary hemangioma is convincing, whereas functional outcome may be compromised because of tumor location, long-persisting macular edema, extensive exudation, and poor initial visual acuity. In patients with extended retinal detachment surgical intervention was still necessary. Although proton beam therapy is proven to be a therapeutic option, treatment will remain challenging.

Capillary malformations (port-wine stains) are observed in less than 1 % of neonates and may occur coincidentally with other vascular and nonvascular malformations. Two thirds of lesions occur in the head and neck area and may have important cosmetic and psychological implications for the patients. Treatment with flashlamp-pumped pulsed dye lasers is still the therapy of choice for capillary malformations and can be applied to infants. If the laser device is used appropriately, the rate of persistent side effects is low. Although laser treatment achieves good clearance in the majority of patients with capillary malformations, complete clearance is rare. New therapeutic options are thus urgently required.

The combination of propranolol and pulsed dye laser for the treatment of infantile hemangiomas may be superior to either alone. This case report illustrates the additive effect of propranolol and pulsed dye laser for an infantile hemangioma in a high-risk location. Although thorough clinical trials are needed, combination therapy for infantile hemangiomas may prove to be optimal for efficacy.

Capillary hemangioma is considered to be one of the most widespread (frequently occurring) vascular ENT tumours. These neoplasms are usually localized in the nasal cavity, sometimes in the larynx or pharynx, and rarely in the outer or middle ear. The principal method for the treatment of this pathology is surgical intervention. Tumour destruction by laser and radiowave radiation finding wide application for the removal of hemangiomas does not substantially lighten the work of a surgeon; moreover the use of these tools is fraught with a high risk of serious intra- and postoperative complications. In an attempt to avoid or reduce bleeding in the course of surgical intervention we used for the first time hemostatic TachoComb and a Fibro-Vein solution. The mode of using these preparations is described in much detail because it determines to a large degree the efficacy and safety of the treatment. The possibility to combine the surgical intervention with the application of TachoComb and a Fibro-Vein solution is considered; also, the advantages of radiowave-induced destruction of hemangiomas are emphasized.

The purpose of this study is to report a case of retinal capillary hemangioma treated with ruthenium-106 brachytherapy combined with intravitreal bevacizumab. A 58-year-old woman presented with blurred vision in her left eye for 15 days. Best-corrected visual acuity (BCVA) was counting fingers at 3 m in her left eye. Examination showed a peripheral endophytic retinal capillary hemangioma, with associated macular edema and diffuse hard exudates in a macular star pattern. B-scan ultrasonography revealed a solid, highly reflective retinal tumor measuring 7.1 × 7.5 mm in basal dimension and 3.5 mm in thickness. The hemangioma and macular edema were treated with ruthenium-106 brachytherapy (500 Gy) followed 1 month later with an intravitreal injection of 1.25 mg (0.05 ml) bevacizumab. After 10 months of follow-up, examination demonstrated involution of the hemangioma, resolution of the macular edema, less hard exudates, and improvement of BCVA to 20/25. Ruthenium-106 brachytherapy combined with intravitreal bevacizumab was associated with significant involution of the choroidal hemangioma with resolution of the macular edema and improvement in visual acuity.

OBJECTIVE: Capillary hemangiomas are benign vascular lesions involving the skin and soft tissues that commonly occur at birth or an early age. Intracranial capillary hemangiomas are extremely rare; only 14 cases have been reported the literature. CASE DESCRIPTION: We describe four patients with capillary hemangiomas. In two of these patients the lesions arose from the cavernous sinus. In the third patient, a large capillary hemangioma arising from the middle cranial fossa extended into the infratemporal fossa. The fourth patient had a left hemorrhagic temporoparietal capillary hemangioma. RESULTS: The first two patients underwent a partial resection, followed by radiotherapy. Local tumor control was achieved in both cases, as shown by the follow-up magnetic resonance imaging. In the third patient the lesion was subtotally removed after embolization. Radiotherapy, performed one year after surgery because of recurrence, allowed tumor control. In the fourth patient surgical removal was total and no adjuvant radiotherapy was required after surgery; follow-up magnetic resonance imaging did not show any recurrence at the one-year follow-up. CONCLUSION: Surgery is an option for symptomatic intracranial capillary hemangiomas. However, because partial removal is associated with a high recurrence rate, capillary hemangiomas that cannot be removed radically should be treated with radiotherapy, which offers the possibility of controlling lesion size and preventing tumor recurrence.

Capillary haemangiomas rarely occur in the auditory canal and have mainly been managed with surgical excision or kept on close follow up for development of symptoms. Radiotherapy, as a treatment method, has not been reported previously in the published work. We describe a study of a capillary haemangioma in the auditory canal of a 26-year-old woman who presented with bleeding. She was treated with radiotherapy, after the lesion was found to be unsuitable for surgery and embolization. The patient remains well 5 years after completion of treatment.

Von Hippel-Lindau disease (VHL disease) is a rare multisystem disorder of autosomal dominant inheritance with high penetrance. Inactivation of the VHL-protein leads to an increased expression of hypoxia induced growth factors. Predilection sites for tumor growth are the retina, the central nervous system and various visceral organs. Retinal capillary hemangioblastoma is one of the earliest manifestations of VHL disease. The lifetime risk of permanent visual loss defined as a visual acuity of 0.5 or less is about 35% in gene carriers. It increases to 60% if there is already retinal capillary hemangioblastoma. If VHL disease is suspected, a careful ophthalmological examination should be included in the clinical screening program. Having confirmed the diagnosis, regular ophthalmoscopic monitoring is essential in order to detect developing tumors at an early stage. Therapeutic options for small to medium sized peripheral tumors are laser or cryocoagulation; larger- hemangioblastomas can be treated by brachytherapy using ruthenium plaques, while asymptomatic juxtapapillary tumors can be observed at regular intervals.

Thermal photocoagulation of small peripheral angiomas is the treatment of choice for capillary hemangiomas in patients with von Hippel-Lindau disease. Larger peripheral angiomas are better treated with beta-ray brachytherapy resulting in improved results in terms of local tumor control and the side effects of treatment. Photodynamic treatment is an alternative option in the management of capillary hemangiomas of the retina. Further improvement of the treatment results of photodynamic therapy may be achieved by combination with intravitreal drugs. External beam radiation using either stereotactic techniques or proton radiation must be considered as experimental. The treatment of juxtapapillary angiomas is still a therapeutic dilemma. Vitreoretinal surgery should be confined to advanced stages with tractional detachment or when no other treatment option is available to salvage the eye.

BACKGROUND AND PURPOSE: Capillary hemangioma of the cavernous sinus is a rare benign skull base tumor that can successfully be treated with radiotherapy. Due to its location, both the tumor itself and the treatment might cause significant functional deficits. Therefore, the different treatment options should be discussed with the patients. CASE REPORT: A case of successful stereotactic fractionated radiotherapy (SFRT) performed after multiple recurrences is described. A 62-year-old male patient with a hemangioma of the right cavernous sinus, orbita and suprasellar region who had previously undergone three surgical procedures received postoperative SFRT for the residual tumor (target volume 85 cm3, Figure 1). SFRT was administered 5 months after surgery with single daily fractions of 2 Gy to a total dose of 40 Gy. RESULTS: No acute or late toxicity of SFRT was observed. Symptomatic improvement was evident 6 months after SFRT. Imaging over a 20-month period showed a continuous and pronounced decrease in residual tumor size (Figure 2). CONCLUSION: Postoperative SFRT with moderate doses is well tolerated and might induce both symptomatic and radiologic improvement of large capillary hemangioma.

OBJECTIVE: To examine the visual and anatomic outcomes of patients with retinal capillary hemangiomas secondary to von Hippel-Lindau (VHL) disease treated with globe-salvaging fractionated external beam radiotherapy (EBRT) after progression of hemangiomas despite initial therapy. DESIGN: Retrospective noncomparative consecutive case series. PARTICIPANTS: Review of medical records of 5 patients with retinal capillary hemangiomas secondary to VHL disease. INTERVENTION: External beam radiotherapy delivered to a total dose of 2160 cGy given over 12 daily fractions. MAIN OUTCOME MEASURES: Data on visual acuity and tumor size were collected at baseline, 1, 3, 6, and 12 months after EBRT, and at final follow-up, using echography, fundus photographs, and clinical examination. RESULTS: Six eyes of 5 patients were treated. Mean follow-up was 28.3 months (range, 6-51). Mean baseline visual acuity was 20/70. Mean visual acuity at last follow-up was 20/45 (range, 20/25-20/60). Tumor volume reduction was 27.5 mm(3) (range, 0.9-109.6 mm(3)). Mean percentage reduction in tumor volume was 39.6% (range, 3.3%-71.1%). CONCLUSIONS: External beam radiotherapy is a useful option in the treatment of retinal hemangiomas secondary to VHL disease that progress despite standard therapy. External beam radiotherapy leads to improvement in visual acuity, reduction in tumor volume, and stabilization of retinal detachment in most patients treated.

BACKGROUND: Angiomatous lesions of the conjunctiva and chronic conjunctivitis are frequently difficult to differentiate. CASE: A 28 year old white male sought help because of a conjunctival swelling. A biopsy made elsewhere had revealed a capillary haemangioma of the conjunctiva. Recently striking alterations of the skin led to the suspicion of a Kaposi's sarcoma. Immunohistochemical and dermatological examinations confirmed the diagnosis of a Kaposi's sarcoma and viral testing of serum revealed an HIV-infection. Besides intensive antiviral therapy, our patient underwent local irradiation of the right eye, the nose and of the left shoulder with an external beam. CONCLUSIONS: Kaposi's sarcoma is the most frequent Aids-associated malignant tumor. In about 30% of all patients with Aids, a Kaposi's sarcoma is diagnosed. The angiomatous character may lead to the histopathological diagnosis of a haemangioma. Human herpes virus 8 is known to be the transforming element.
