Objective To explore the clinicopathological features and misdiagnosed causes of choroidal hemangioma. Methods Seven misdiagnosed cases(7eyes) of choroidal hemangioma,which were enucleated,were analysed retrospectively. Results One of the 7 cases was misdiagnosed as absolute phase of the secondary glaucoma,and 6 of them as choroidal melanoma before the enucleation.The majority of cases in this series manifested themselves clinically and pathologically in progressive loss of visual acuity and a flat elevated tumor located at the posterior ocular fundus near the optic disc and associated with exudative retinal detachment.And also there were occasionally small focal or linear pigmentary deposites obser ved on the surface of the neoplasm. Conclusion A flat elevated discoid tumor in the posterior fundus with extensive exudative retinal detachment might be a clinicopathological feature of the choroidal hema ngioma.

Objective To observe the therapeutic effect of photodynamic therapy (PDT) and transpupillary thermotherapy (TTT) on circumscribed choroid hemangioma (CCH).Methods Clinical data of 32 patients (33 eyes) with CCH diagnosed by ocular fundus examination, fundus fluorescein angiography (FFA),indocyanine green angiography (ICGA),optical coherence tomography (OCT) and Bultrasound examination were retrospectively analyzed.Before the therapy the selected cases had best corrected visual acuity (BCVA) of fingercounting/15 cm-0.2,the sizes of 2-10 disc diameter (DD) and serous retinal detachment.Twentyone patients (22 eyes) whose tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent TTT.The parameters of TTT included: Iris 810 nm infra red diode laser，7001200 mW,60 s,and 1-3 spots. Eleven patients (11 eyes) with tumor located at the posterior pole except for the papillomacular bundle and arch ring area underwent. After 15 minutes of intravenous injection with Visudyne, laser irradiation with the wavelength of 689 nm was performed with the time of 83-123 s. The followup period was 12-48 months with the mean of 25.6 months.BCVA and results of indirect ophthalmoscopy,fundus photogrphy,FFA,ICGA,OCT and B ultrasound examination were exanmined and anlyzed.Results In the 22 eyes in TTT group, the BCVA improved in 15 and kept unchanged in 7;the results of fundus examinations showed healed retina and atrophy tumor with greywhite organized scar;the results of FFA revealed no fluorescence leakage and scar fluorescence dyeing of the lesion in later period；the results of OCT indicated disappeared retinal detachment, completely absorbed subretinal liquid and increased reflection of choroid tumor with scar；the results of Bultrasound examination showed no retinal detachment and atrophy tumor.In 11 eyes in PDT group,the BCVA improved in 9, unchanged in 2;the results of fundus examinations showed atrophy tumor with pigmentation；the results of FFA revealed disappeared fluorescence leakage；the results of OCT indicated completely absorbed subretinal liquid；the results of B-ultrasound examination showed atrophy tumor.Conclusions Both TTT and PDT can make the tumor atrophy,improve BCVA or keep it still;but apply to different area.
Objective To explore the effectiveness and appropriate energy parameters of high-intensity focused ultrasound (HIFU) in treating infant hemangiomas. Methods Between January 2009 and September 2010, 60 infants with hemangioma were treated. There were 23 boys and 37 girls, aged from 3 to 30 months with an average of 10 months. These hemangiomas were located at head and face (24 cases), trunk (15 cases), l imb (16 cases), buttocks (2 cases), perineum (1 case),and multiple lesions (cervix, abdomen, and upper l imbs, 2 cases). The size of hemangiomas ranged from 0.8 cm × 0.6 cm to 6.0 cm × 5.0 cm. The 60 infants were randomly divided into 3 groups: groups A, B, and C (n=20) based on different ultrasound energies used in treatment. The lesion surface was irradiated with 3-5 mm/second for 5 continuously by ultrasonic therapeutic apparatus at a frequency of 9 MHz, impulse of 1 000, and 10% of scanning overlap; the powers of 3.5, 4.0, and 4.5 W were used in groups A, B, and C, respectively, 3 times as a course of treatment with 1 month interval. The effect and ulcer and scar risk in irradiation region were observed after 6 months of treatment. Results All cases were treated for one course. After 6 months of treatment, no significant difference in the effect was found among 3 groups based on hemangioma treatment judging criterion (P gt; 0.05). Neither ulcer nor scar occurred in group A; ulcer occurred in 4 cases (20%) of group B with superficial scars, and in 7 cases (35%) of group C with obvious scars. The rates of ulcer and scar in groups B and C were significantly higher than that in group A (P lt; 0.05). Conclusion HIFU irradiating is one of effective methods for treating infant hemangioma, but the appropriate energy was below 3.5 W.
Objective To explore the mechanism of laser and photodynamic therapy (PDT) of hemangioma. Methods A total of 48 6-month-old male chickens were divided into 6 groups, with 8 in each group. The side with the untreated comb served as the control. Group A was the control group. In groups B and C, the combs received laser irradiation once of 10 J/cm2 and 15 J/cm2, respectively, for 2-3 minutes. In group D, hematoporphyrin monomethyl ether (HMME) of 10 mg/kg was injected into the left-side axillary vein once. In groups E and F, the combs received laser irradiation of 10 J/cm2 and 15 J/cm2, respectively, after 10 mg/kg HMME was injected for 10 minutes into the left-side axillary vein. On the 14th day, HE staining was performed and the decrease rate of the number of capillary vessels was calculated. Besides, TUNEL stainingwas conducted to observe the condition of capillary endothel ium apoptosis. Results No animal died after the operation,the combs in groups A and D had no obvious changes in shape and color, but the ones in the other groups had leukasmus, edema, necrosis and dark crust. According to histological observation, in groups A and D, the combs had no obvious changes. But in the other groups, tissue exudation, edema, inflammatory cell exudation, decreasing number of vessels, waning vascular cal iber, thrombus, and partial capillary endothel ium apoptosis were found. The decrease rate of the number of capillary vessels was as follows: 7.87% ± 2.50% in group A, 48.58% ± 5.10% in group B, 57.58% ± 8.17% in group C, 8.84% ± 3.13% in group D, 61.26% ± 16.87% in group E and 68.56% ± 10.54% in group F. The apoptosis index in all groups was 1.05 ± 0.76, 82.22 ± 6.18, 94.13 ± 1.64, 1.38 ± 0.52, 101.88 ± 5.94, 104.88 ± 6.22, respectively. There were significant differences between groups B, C, E, F and groups A, D in the above two items (P lt; 0.01). There were significant differences between groups B and E as well as between groups C and F (P lt; 0.01). There were no significant differences between groups B and C as well as groups E and F (P gt; 0.05). Conclusion Apoptosis of capillary endothel ium maybe play an important role in the laser and photodynamic therapy of hemangioma apart from the direct effect of laser.
Abstract： Objective To investigate the clinicopathological characteristics, improve the accuracy of clinical diagnosis， and reduce postoperative complications of thoracic hemangioma. Methods Clinical records of 9 patients with thoracic hemangioma who underwent surgical resection in West China Hospital of Sichuan University from January 2006 to August 2012 were retrospectively analyzed. There were 2 males and 7 females with their average age of 47.9±19.3 （18-71）years. Six patients underwent thoracotomy， 1 patient underwent complete video-assisted thoracoscopic surgery （VATS）， 1 patient underwent video-assisted mini-thoracotomy， and 1 patient underwent staged operations which were performed by neurological surgeons and thoracic surgeons separately. Imaging characteristics, intraoperative gross tumor features, and pathological characteristics of resected hemangioma specimens were analyzed. Clinical outcomes of different surgical strategies for the treatment of hemangioma were compared. Results Nine patients with thoracic hemangioma were included in this study. Imaging studies showed the tumor as a round-shaped mass in 66.7% （6/9） of these patients and a lobulated mass in the remaining 33.3% （3/9） patients. Magnetic resonance imaging （MRI） assessment was helpful for preoperative diagnosis of hemangioma， with T2 weighted imaging tumor enhancement as the main MRI feature. Thoracic operation time was 106.3±60.1 （60-192） min， and intraoperative blood loss was 91.1±43.7 （30-150） ml. All the patients were followed up for 3-6 years except 1 patient who was followed up for 1 month. None of the patients had hemangioma-related death， recurrence or metastasis during follow-up. Conclusions Thoracic hemangiomas are usually benign entities and often locate in the mediastinum. Surgical strategies should be determined by the size and location of the tumor as well as the surgeon’s technique level. VATS has the advantages of being minimal invasive, causing less intraoperative blood loss and shorter length of hospital stay for the treatment of hemangioma. Resection of a dumbbell-type hemangioma may need cooperation between neurological and thoracic surgeons.
Objective To evaluate the therapeutic effects of pingyangmycin in treatment of body surface hemangioma in children. Methods The clinical data of 1 658 children patients with hemangioma on body surface in which pingyangmycin was injected between January 1997 and January 2008 were analyzed retrospectively． Results All 1 658 patients were observed for 6-12 months, with average of 10.83 months． The total effective rate was 97.09%. Compared among different types of hemangioma, total effective rate had significant difference (χ2=203.12， P＜0.01), and complete remission (CR) rate had significant difference (χ2=287.97， P＜0.01). The therapeutic effect of pingyangmycin in treatment of cavernous hemangioma was better than that of strawberry hemangioma, mixed hemangioma and portwine stain, which was better instrawberry hemangioma than mixed hemangioma and portwine stain, and which was lower in portwine stain than other hemangiomas. Fifty-four patients (3.26%) caught partial necrotic ulcer of hemangioma. There were 418 cases (25.21%) of fever and 3 cases (0.18%) of allergic shock. Conclusion Intratumorally pingyangmycin injection is a simple， safe and effective therapy for hemangioma of body surface in children．
To analyze the cl inical effect of retained copper needles well as neoplasm l igation, retained copper needles associated with Pingyangmycin injection and inserted copper needles followed by DC in treating hemangiomaso as to treat hemangioma with copper needles. Methods From January 1999 to January 2006, 55 cases of hemangioma in superficial body were treated with copper needles, including 28 males and 27 females and aging 3-50 years(median 19 years). There were 42 cases of cavernous hemangiomas, 4 cases of racemose hemangiomas and 9 cases of multipl icate hemangiomas. The size ranged from 6 cm × 4 cm to 40 cm × 25 cm. Retaining copper needles were used in 29 cases, retaining copper needles with l igating neoplasm in 21 cases, retaining copper needles associated with Pingyangmycin injection in 3 cases and inserting copper needles followed by DC in 2 cases. Results Fifty cases were treated with copper needles only once and 5 cases twice. All cases were followed up for three to eighteen months. According to Wang Yongjie’s criterion, 15 (27.3%) cases were cured, 38 (69.1%) improved, and 2（3.6%）failed to respond; the response rate was 96.4% (53). Conclusion Copper needle is efffective for treating hemangioma in superficial body. Retaining copper needles with l igation neoplasm or with Pingyangmycin injection can achieve better effect.
ObjectiveTo observe the effectiveness of radiotherapy for refractory choroidal hemangioma. MethodsEight patients (8 eyes) with choroidal hemangioma were enrolled in this retrospective study. All the patients had received laser or photodynamic therapy before without effectiveness. The patients included 7 males and 1 females. The age was ranged from 11 to 54 years old, with an average of (27.50±15.18) years. All the patients were affected unilaterally, including 3 right eyes and 5 left eyes. There were 5 eyes with circumscribed choroidal hemangioma, 3 eyes with diffused choroidal hemangioma. All eyes had extensively exudative retinal detachment. The vision was from light sensation to 0.01. The volume of the tumors was ranged from 1.96 to 5.35 cm3, with a mean of (3.37±1.06) cm3. All the patients were treated with X rays by conventional fractional radiotherapy. Four of 8 patients were applied 24Gy totally in 8 fractions, while the other 4 patients were applied 46Gy in 23 fractions. Follow-up period ranged from 7 to 95 months, with medium of 42 months. ResultsRetinas reattached in all the eyes while exudation being absorbed. No retinal detachment happened again. To the last follow-up, the vision was from light sensation to 0.6. Visual activity improved in 6 eyes while 2 eyes improved obviously. Visual acuity was stable in remaining 2 eyes. The volume of the tumors decreased to 1.24-2.16 cm3, with a mean of (1.68±0.30) cm3. The percentage of the tumor decreased by 14.6-72.7, with an average of (44.89±21.30)%. No radiotherapy-associated complication occurred. ConclusionRadiotherapy is an efficient and safe treatment for refractory choroidal hemangioma.
ObjectiveTo observe the clinical effect of prolonged photodynamic therapy (PDT) irradiation time combined with intravitreal injection of ranibizumab in the treatment of circumscribed choroidal hemangioma (CCH).MethodsA retrospective clinical study. From March 2012 to March 2018, 51 eyes of 51 patients diagnosed in Shenzhen Eye Hospital were included in the study. Among the patients, the tumor of 36 eyes were located in macular area, of 15 eyes were located outside macular area (near center or around optic disc). All patients underwent BCVA, color fundus photography, FFA, ocular B-scan ultrasonography and OCT examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. OCT showed 48 eyes with macular serous retinal detachment. of 36 eyes with tumor located in macular area, the logMAR BCVA was 0.05±0.05, the tumor thickness was 4.5±2.2 mm, the diameter of tumor was 9.7±3.6 mm. Of 15 eyes with tumor located outside macular area, the logMAR BCVA was 0.32±0.15, the tumor thickness was 3.8±1.4 mm, the diameter of tumor was 7.7±1.9 mm. PDT was performed for all eyes with the irradiation time of 123 s. After 48 h, all patients received intravitreal injections of 0.5 mg ranibizumab (0.05 ml). At 1, 3 and 6 months after treatment, the same equipment and methods before treatment were used for related examination. BCVA, subretinal effusion (SRF), tumor leakage and size changes were observed. BCVA, tumor thickness and diameter before and after treatment were compared by t test.ResultsAt 6 months after treatment, the tumor was becoming smaller without scar formation. FFA showed that the blood vessels in the tumor were sparse compared with those before treatment, and the fluorescence leakage domain was reduced. OCT showed 43 eyes of macular serous detachment were treated after the combined treatment. The logMAR BCVA were 0.16±0.15 and 0.55±0.21 of the eyes with tumor located in or outside macular area, respectively. The difference of logMAR BCVA between before and after treatment was significant (t=－2.511, －2.676; P=0.036, 0.040). Both the tumor thickness (t=3.416, 3.055; P=0.011, 0.028) and diameter (t=4.385, 4.171; P=0.002, 0.009) of CCH patients were significantly reduced compared with that before treatment.ConclusionThe tumor of CCH can be reduced by prolonged PDT irradiation time combined with intravitreal injection of ranibizumab.
