RESUMEN
AIM: This study aims to explore the potential of Osmundacetone (OSC) as a new treatment for infantile hemangiomas (IH), the most common benign tumors in infancy. Currently, propranolol serves as the primary treatment for IH, but its effectiveness is limited, and it poses challenges of drug resistance and side effects. Therefore, there is a pressing need to identify alternative therapies for IH. METHODS: The effects of OSC on the proliferation and apoptosis of HemECs (endothelial cells from hemangiomas) were assessed using CCK-8 assay, colony formation assay, HOCHEST 33342 staining, and flow cytometry. Western blot analysis was performed to investigate OSC's influence on Caspases and angiogenesis-related proteins. Animal models were established using HemECs and BALB/c mice, and histological and immunohistochemical staining were conducted to evaluate the impact of OSC on mouse hemangiomas, VEGFR2, and MMP9 expression. RESULTS: OSC treatment significantly reduced HemECs' viability and colony-forming ability, while promoting apoptosis, as indicated by increased HOCHEST 33342 staining. OSC upregulated the protein expression of Bax, PARP, Caspase9, Caspase3, AIF, Cyto C, FADD, and Caspase8 in HemECs. In animal models, OSC treatment effectively reduced hemangioma size and improved histopathological changes. OSC also suppressed VEGFR2 and MMP9 expression while elevating Caspase3 levels in mouse hemangiomas. CONCLUSION: OSC demonstrated promising results in inhibiting HemECs' proliferation, inducing apoptosis, and ameliorating pathological changes in hemangiomas in mice. Moreover, it influenced the expression of crucial caspases and angiogenesis-related proteins. These findings suggest that OSC holds potential as a novel drug for clinical treatment of IH.

Circumscribed choroidal hemangioma is a rare vascular hamartoma of the choroid, presenting as a red-orange mass at the posterior pole on fundoscopic examination. Despite its benign origin, associated complications such as subretinal fluid, serous retinal detachment, retinoschisis and neovascular glaucoma may lead to serious visual impairment in more than half patients. Because of its similarity to amelanotic choroidal melanoma and choroidal metastasis, differential diagnosis is still challenging for specialists. Multimodal imaging such as ultrasonography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography guides the clinician to the correct diagnosis and the proper follow-up. Treatment is indicated in symptomatic cases in order to resolve exudation and improve visual acuity. Treatment options include photocoagulation, transpupillary thermotherapy, radiation therapy, photodynamic therapy and anti-vascular endothelial growth factor therapy. Currently, photodynamic therapy is the treatment of choice due to its effectiveness and safety. The purpose of this review is to describe the latest knowledge in the etiopathogenesis of the circumscribed choroidal hemangioma, the most recent multimodal imaging findings, and the available treatment options.

PURPOSE: To determine the safety and efficacy of computed tomography (CT) fluoroscopy-guided percutaneous transhepatic sclerotherapy with a bleomycin/ethiodized oil emulsion for symptomatic giant hepatic hemangiomas. MATERIALS AND METHODS: The procedure was performed on 22 patients with symptomatic giant hepatic hemangiomas in an outpatient setting between 2018 and 2020. All patients were followed clinically and underwent contrast-enhanced magnetic resonance imaging after 1 month and again at a mean time of 15 months ± 2. Adverse events were classified according to the Common Terminology Criteria for Adverse Events (CTCAE, v5.0), in which a severe adverse event was defined as an adverse event with a grade of ≥3. The desired radiologic response (volume and index size) and improvement of pain intensity (visual analog scale [VAS]) and other symptoms were recorded as outcomes. RESULTS: Overall, patients showed a 36.4% ± 8.6 reduction in volume and a 14% ± 1.6 reduction in index size after 1 month, with P values of .002 and .001, respectively. The final follow-up volume and index size were 194.7 cm3 ± 25.8 and 77 mm ± 36, respectively. Moreover, a 53.0% ± 7 reduction in volume and 22% ± 3.7 reduction in index size during the final imaging were reported, with the P values of .001 and .001, respectively. Significant reductions in the mean pain intensity (90% of patients with lower VAS scores after intervention) and symptoms were reported. Four patients were classified as clinically unsuccessful, and were recommended further procedures for residual pain. CONCLUSIONS: CT fluoroscopy-guided transhepatic sclerotherapy is an effective, safe, and minimally invasive method to manage giant hepatic hemangiomas in an outpatient setting.

PURPOSE: To report the effectiveness and safety of transcatheter arterial sclerosing embolization (TASE) for the treatment of parotid infantile hemangiomas that did not respond appreciably to propranolol. MATERIALS AND METHODS: A total of 21 infants (12 male and 9 female) with large propranolol-resistant infantile hemangiomas in the parotid region were enrolled in this study. During TASE, the feeding arteries of the lesions were embolized using pingyangmycin-lipiodol emulsion and polyvinyl alcohol particles (300-500 µm) to reduce the blood flow rate. All children were followed up as outpatients at 2 weeks and monthly thereafter. The curative effect was evaluated at the 1- and 3-month follow-up visits. RESULTS: Nine lesions were located on the right side of the parotid gland, whereas 12 were located on the left side. The feeding arteries in all patients originated from branches of the external carotid artery. TASE was technically successful in all patients. The mean (± SD) maximal diameter of the hemangiomas significantly decreased from 6.50 cm ± 2.28 before treatment to 3.56 cm ± 1.84 at 1 month after TASE (P <. 05). Three months after TASE, the mean maximal diameter further significantly decreased to 1.94 cm ± 1.58 (P <. 05). During the follow-up period, 16 cases were rated as excellent and 5 as good; no recurrence or serious complications were noted. Minor side effects, such as slight pain, mild fever, and tissue swelling, were observed. CONCLUSIONS: TASE significantly decreased the size of the parotid hemangiomas with minor side effects during a short follow-up period.

BACKGROUND: Cherry angiomas are benign vascular proliferations of endothelial cells associated with aging. Currently, no mainstay of treatment for these vascular anomalies exists. OBJECTIVE: To review existing evidence-based therapies for the treatment of cherry angiomas. METHODS: A literature search in May 2019 was performed with PubMed Database and Cochrane Library using the following terms: "cherry angioma," "senile hemangioma," "senile angioma," "cherry hemangioma," and "Campbell de Morgan spots." RESULTS: Ten studies included in this systematic review reported laser therapy and nonlaser therapy as efficacious treatments for cherry angiomas. Among the laser therapies, pulsed dye laser (PDL) was preferred over potassium-titanyl-phosphate (KTP) and electrodessication (ED), based on decreased procedure-related pain. The neodymium-doped yttrium aluminum garnet (Nd:YAG) laser 1064 nm produced less pigmentary complications, whereas KTP and PDL risked pigmentary changes in darker-skinned individuals. Nonlaser therapies included cryotherapy, sclerotherapy, electrosurgery (i.e., ED, electrocoagulation), and radiofrequency ablation. No therapy proved to be superior. CONCLUSION: A variety of therapeutic modalities exist for the treatment of cherry angiomas. However, a limited number of high-quality studies explored the efficacy of treatments and compared treatment modalities. Light-based methods such as argon, KTP, Nd:YAG, intense pulsed light, and PDL, along with non-light-based interventions such as cryotherapy, electrosurgery, and sclerotherapy effectively treated cherry angiomas.

OBJECTIVE: Choroidal hemangioma (CH) is a benign vascular tumor that induces subretinal fluid collection or exudative retinal detachment and consequent visual symptoms. Current standard treatments for CH include cryotherapy, diathermy, photocoagulation, photodynamic therapy, transpupillary thermotherapy, and radiation therapy. Stereotactic radiosurgery has recently been applied to the treatment of CH because of its characteristic stiff dose-fall-off and accuracy. We have adopted gamma knife radiosurgery (GKRS) to treat CH and have retrospectively assessed tumor volume reductions and improvements to visual acuity achieved thereby. METHODS: Fourteen patients with CHs were treated with GKRS from November 2006 to December 2017. Eight patients had circumscribed CH, and 6 exhibited diffuse CHs and were diagnosed with Sturge-Weber syndrome. The mean age of patients was 27.1 years (range: 8-68 years) and the mean duration of clinical or radiological follow-up was 40.2 months (range: 5-105 months). The mean volume of the tumors at the time of GKRS was 533.5 mm3 (range: 124-1150 mm3), and the mean prescribed marginal dose was 11.6 Gy (range: 10-16 Gy) with 50% isodose lines. RESULTS: The tumor volume decreased by the last follow-up in all patients. The visual acuity improved in 9 patients (64%) and decreased in 1 (7%). Six patients (43%) required trans-pars plana vitrectomy before or after GKRS. There were no symptomatic complications from radiation injury during the follow-up periods. CONCLUSIONS: GKRS could be an acceptable alternative treatment for symptomatic CH when standard therapy is not feasible.

The purpose of this study is to describe the effects and complications of photodynamic therapy (PDT) on Chinese patients with circumscribed choroidal hemangioma (CCH). In this retrospective study, 22 CCH patients who underwent PDT performed 15 min after the injection of intravenous verteporfin (6 mg/m2)with multiple 83-second laser spots at 689 nm (50 J/cm2) were studied. Fluorescein angiography and/or indocyanine green angiography, B-scan ultrasonography and optical coherence tomography were performed in all patients. Follow-up was performed until 12 months post-treatment. All patients were treated with one session, except 1 case with prior transpupillary thermotherapy history. At the 12-month follow-up, the mean of the best corrected visual acuity (BCVA) increased from 0.40 ± 0.38 to 0.56 ± 0.42 (p < 0.05), tumors became thinner (1.96 ± 2.65 mm vs. 4.31 ± 2.04 mm) (p < 0.05), and exudative detachment were diminished. The mean fovea center thickness (FCT) decreased from 540.1 ± 470.6 to 171.6 ± 79.3 µm at the 3-month follow-up. The 12-month BCVA was correlated with prior laser treatment, symptom duration, baseline CCH diameter and thickness, baseline FCT and cystoid macular edema. One patient developed a branch retinal artery occlusion. In conclusion, PDT is an effective and safe treatment for CCH. Specific PDT protocols for CCH should be standardized. The retinal arteriole should be spared during the treatment.

Objective We investigated the efficacy and safety of 1064 nm Nd: YAG laser, intense pulsed light (IPL), and lauromacrogol injection in the treatment of hemangioma, in order to evaluate the value of color Doppler ultrasound guidance in choosing the optimal treatment modality. Methods Infantile patients who were clinical diagnosed as hemangiomas were randomly divided into group A, who had color Doppler ultrasound examinations before the treatment, and group B who had the treatment without ultrasound evaluation. Patients in the group A were assigned into subgroups according to the depth of lesion by sonography: group A-1 for those who had a lesion depth <1.2 mm, and took intense pulsed light therapy; group A-2 for those who had a lesion depth ≥1.2mm and < 3 mm, and took long pulse 1064 nm Nd:YAG laser therapy; group A-3 for those who had a lesion depth ≥3mm and <5 mm, and were treated by IPL combined with long pulse 1064 nm Nd:YAG laser treatment; Group A-4 for those who had a lesion depth ≥5 mm, and took lauromacrogol injection therapy. Patients in the group B took long pulse 1064 nm Nd:YAG laser treatment without preoperative ultrasound evaluation. The efficacy and adverse reactions of the treatments between the groups were evaluated and compared statistically.Results Totally 113 patients with 128 skin lesions were enrolled in this study, 85 in the group A (mean age 6.8±7.9 months) and 28 in the group B (mean age 6.9±9.9 months). The mean depth of hemangioma was 3.3±1.1 mm in the group A, ranging from 0.5-7.8 mm, with 0.8±0.4 mm, 2.2±0.4 mm, 4.2±0.6 mm and 6.2±0.7 mm in group A1, A2, A3 and A4, respectively. The cure rates and effective rates in the group A were significantly higher than those in the group B (cure rates: 64.5% vs 56.3%, U=3.378, P=0.045; effective rates: 89.5% vs 78.1%, U=4.163, P=0.041). The adverse effect rates of the group A (vesicle 20.0%, pigmentation 46.9%, scarring 17.7%) were lower than those of the group B (vesicle 21.9%, pigmentation 60.4%, scarring 25.0%). Incidences of pigmentation and scarring were statistically significantly different (U=3.884, P=0.034, and U=4.016, P=0.032 respectively) between the two groups.Conclusion With the guidance of color Doppler ultrasound, the efficacy and safety of long pulse 1064 nmNd:YAG laser, intense pulsed light, and lauromacrogol injection in the treatment of infantile hemangioma have better outcomes compared to laser treatment alone without preoperative ultrasound examination.

BACKGROUND: Transarterial embolization of liver hemangiomas has not been considered to be consistently effective. METHODS: The charts of 25 patients who underwent superselective transarterial chemoembolization with the bleomycin-lipiodol emulsion were evaluated retrospectively. RESULTS: Twenty-two patients had abdominal pain; asymptomatic/vaguely symptomatic enlargement was the treatment indication in three patients. A single session was conducted in 17 patients, two sessions in 7 and three sessions in one. After the first session, lesion volume decreased by median (range) 51% (10-92%) from median (range) 634 (226-8435) to 372(28-4710) cm3 (p < 0.01), after a median period of 4 months (range 2-8). A second session was performed in eight patients (median (range) initial volume 1276 (441-8435) cm3) with persistent complaints and/or large lesions receiving feeders from both right and left hepatic arteries (staged treatment). Median (range) lesion size decreased further from 806 (245-4710) to 464 (159-2150) cm3 (p < 0.01). Three patients experienced a postembolization syndrome that persisted after the first week. Seventeen of the 22 symptomatic patients (77%) reported resolution or marked amelioration of complaints. Regrowth after initial regression was not observed during median (range) 14 (8-39) months of follow-up (n:18). CONCLUSION: Transarterial chemoembolization with the bleomycin-lipiodol emulsion is a potential alternative to surgery for symptomatic/enlarging liver hemangiomas. Volume reduction is universal, and symptom control is satisfactory. Centrally located and very large (>1000 cm3) lesions may require two sessions.

Intraarticular benign tumors are rare lesions in many cases seen as incidental findings. One of the typical lesions is the diffuse or nodular form of pigmented villonodular synovitis, which needs a complete surgical removal. Magnetic Resonance Imaging (MRI) is diagnostic in most of the cases because of the intracellular iron content which shows an at least in some parts dark T2-sequence. Adjuvant therapies as radiosynoviorthesis should be considered in diffuse or recurrent lesions. Synovial Chondromatosis represents a metaplastic disorder of the synovial membrane resulting in the production of loose cartilage bodies. Also in this dissease synovectomy or, in late cases, removal of the loose bodies only, is recommended. Synovial hemangiomas are hamartomas which may lead to pain or restriction of movement. In these cases total or partial resection is justified. Alternative treatment options such as laserablation may be possible. Lipoma arborescens represents a proliferative lipoid lesion of the subsynovial region leading to villonodular synovial proliferation. If clinically symptomatic, resection by arthroscopic or open synovectomy is recommented.

Propranolol was first used in 2008 to treat hemangioma; its efficacy and safety have since changed the classical treatment indications. Infantile hepatic hemangioma presents as a spectrum of clinical conditions varying from simple asymptomatic lesions to lethal complications. Tufted hemangioma and Kaposiform hemangioendothelioma are congenital vascular tumors that lead to Kasabach-Merritt syndrome. Hemangiomas, like pure arteriovenous malformations, can cause hyperdynamic heart failure, and diffuse nodular-type hemangiomas can present with hypothyroidism. Respiratory problems and hepatic failure can be associated with diffuse nodular-type liver hemangiomas. There is a spectrum of approaches to management, varying from "watchful waiting" to liver transplant. In the age of propranolol, there has been a prominent change in the infantile hepatic hemangioma treatment algorithm. Our suggestion is early treatment with 3 mg/kg/day propranolol plus 1.0 to1.5 mg/kg/day prednisolone in all patients. This protocol is the most effective strategy for type 3 infantile hepatic hemangioma. Approximately one-third of patients with abdominal compartment syndrome in the era before propranolol treatment required liver transplant; this new treatment obviates transplant for many of these patients.

OBJECTIVE: To study the effectiveness and limitations of photodynamic therapy (PDT) as treatment of choice in patients with symptomatic circumscribed choroidal haemangioma. METHODS: A retrospective study was conducted on 16 patients (13 men and 3 women, with mean age of 54.88 years) with circumscribed choroidal haemangioma, who attended our centre and were treated with PDT in the last 7 years. RESULTS: All patients had circumscribed choroidal haemangioma, which caused a decrease in visual acuity (VA) secondary to the presence of intraretinal microcystic oedema or neurosensory detachment. The mean initial VA was 0.23, and the final mean VA after performing PDT was 0.38 (all the VA were measured in decimal scale). It should be noted that patients needed a mean of 1.69 PDT sessions. Three of the patients needed rescue treatment with trans-pupillary thermotherapy, intravitreal injection of anti-vascular endothelial growth factor (ranibizumab, aflibercept) or a dexamethasone intravitreal implant (Ozurdex®). The indication for a change of treatment was the persistence of intraretinal microcystic oedema and/or neurosensory detachment (or incomplete resolution) after 3 PDT sessions. As overall results, 62.5% of patients evolved into anatomical and functional (increase in AV or stability) resolution. CONCLUSIONS: PDT is a straight forward and fast procedure, with a good anatomical and functional response, causing minimal damage to adjacent vessels.

OBJECTIVES: Surgical resection represents the main curative treatment for giant hepatic haemangioma (GHH). The aim of this study was to compare the respective outcomes of hepatic enucleation (HE) and hepatic resection (HR) for GHH. METHODS: Giant hepatic haemangioma was defined as haemangioma of 5-15 cm in size. A prospectively maintained database consisting of a series of consecutive patients who underwent HE or HR of GHH from January 2004 to December 2013 was analysed. RESULTS: Hepatic enucleation was performed in 386 (52.9%) patients and HR in 344 (47.1%) of a final cohort of 730 patients. The median size of GHH was similar in the HR and HE groups (9.8 and 10.6 cm, respectively; P = 0.752). The HE group had a shorter median operative time (150 min versus 240 min; P = 0.034), shorter median hospital stay (5.7 days versus 8.6 days; P < 0.001), lower median blood loss (400 ml versus 860 ml; P < 0.001), and fewer complications (17.6% versus 28.2%; P < 0.001) than the HR group. Quality of life scores in both the HR and HE groups significantly improved compared with preoperative levels and were similar to those found in healthy Chinese individuals following surgery, confirming the efficacy of both treatments. CONCLUSIONS: Hepatic enucleation was associated with favourable operative outcomes compared with HR and is a safe and effective alternative to partial hepatectomy for GHH.

A prototype low-cost RGB imaging system consisting of a commercial RGB CMOS sensor, RGB light-emitting diode ring light illuminator, and a set of polarizers was designed and tested for mapping the skin erythema index, in order to monitor skin recovery after phototherapy of vascular lesions, such as hemangiomas and telangiectasias. The contrast of erythema index (CEI) was proposed as a parameter for quantitative characterization of vascular lesions. Skin recovery was characterized as a decrease of the CEI value relative to the value before the treatment. This approach was clinically validated by examining 31 vascular lesions before and after phototherapy.

BACKGROUND AND OBJECTIVE: To report the outcome of treating circumscribed choroidal hemangioma (CCH) using transpupillary thermotherapy (TTT). PATIENTS AND METHODS: An infrared diode laser was used at 810 nm with a median spot size of 2.5 mm, power of 550 mW, and duration of 6.5 minutes; the median number of sittings was two. TTT spared the center of the macula when CCH involved the fovea. RESULTS: The mean age was 36 years (range: 13 to 63 years). CCH was subfoveal in 37.5% of the eyes and exudative retinal detachment was evident in all eyes. The tumor dimensions included thickness (median: 4.05 mm; range: 2.2 to 9.1 mm), horizontal diameter (median: 11 mm; range: 6 to 17.7 mm), and vertical diameter (median: 9.4 mm; range: 5.9 to 15.8 mm). After TTT, visual acuity improved in 44%, was maintained in 37%, and worsened in 19% of eyes. Likewise, tumor regression was achieved in thickness, vertical, and horizontal diameter in proportion of 20%, 15%, and 11%, respectively. The exudative retinal detachment resolved in 94% of eyes at the last follow-up. The median follow-up was 9.5 months. CONCLUSION: Macula-sparing TTT was effective in causing regression of CCH and resorption of associated exudative retinal detachment, and helped in preserving or improving vision in 81% of treated eyes.

PURPOSE: To review the clinical features and management of circumscribed choroidal hemangioma. METHODS: Twenty eight cases of circumscribed choroidal hemangioma diagnosed at Tokyo Medical University Hospital from 1991 through 2008 were reviewed. We retrospectively studied the frequency of the individual tumors, gender, age, size of tumors, presence of serous detachment and hyperopia, management and outcome. RESULTS: Sixteen patients were men and 12 cases were women. The average age was 55 years. The average basal diameter of the tumors was 3.3 optic disc. Serous retinal detachment was observed in 19 cases (70%). Seventeen eyes agreed with the definition of hyperopia, 10 cases (59%) developed hyperopia. Thirteen cases (46%) were observed without any treatment, 10 cases(36%) were treated with transpupillary thermotherapy (TTT) and 5 cases (18%) were treated with dye laser. Thirteen cases (46%) showed improvement, 13 cases (46%) remained constant and 2 cases (7%) showed deterioration. CONCLUSION: Circumscribed choroidal hemangioma is a relatively rare clinical entity. The management should be tailored to the individual patients including the tumor size presence of serous detachement and visual acuity.

Optical fiber contact probe diffuse reflectance spectroscopy and remote multispectral imaging methods in the spectral range of 400 to 1100 nm were used for skin vascular malformation assessment and recovery tracing after treatment by intense pulsed light. The results confirmed that oxy-hemoglobin relative changes and the optical density difference between lesion and healthy skin in the spectral region 500 to 600 nm may be successfully used for objective appraisal of the therapy effect. Color redness parameter a* = 2 is suggested as a diagnostic border to distinguish healthy skin and vascular lesions, and as the indicator of phototreatment efficiency. Valuable diagnostic information on large area (>5 mm) lesions and lesions with uncertain borders can be proved by the multispectral imaging method.

PURPOSE: To investigate the usefulness of computed tomographic (CT) spectral imaging parameters in differentiating small (≤3 cm) hepatic hemangioma (HH) from small hepatocellular carcinoma (HCC), with or without cirrhosis, during the late arterial phase (AP) and portal venous phase (PVP). MATERIALS AND METHODS: This prospective study was institutional review board approved, and written informed consent was obtained from all patients. The authors examined 49 patients (39 men, 10 women; 65 lesions) with CT spectral imaging during the AP and the PVP. Twenty-one patients had HH; nine, HCC with cirrhosis; and 19, HCC without cirrhosis. Iodine concentrations were derived from iodine-based material-decomposition CT images and normalized to the iodine concentration in the aorta. The difference in iodine concentration between the AP and PVP (ie, iodine concentration difference [ICD]) and the lesion-to-normal parenchyma ratio (LNR) were calculated. Two readers qualitatively assessed lesion types on the basis of conventional CT characteristics. Sensitivity and specificity were compared between the qualitative and quantitative studies. The two-sample t test was performed to compare quantitative parameters between HH and HCC. RESULTS: Normalized iodine concentrations (NICs) and LNRs in patients with HH differed significantly from those in patients with HCC and cirrhosis and those in patients with HCC without cirrhosis: Mean NICs were 0.47 mg/mL ± 0.24 (standard deviation) versus 0.23 mg/mL ± 0.10 and 0.23 mg/mL ± 0.08, respectively, during the AP and 0.83 mg/mL ± 0.38 versus 0.47 mg/mL ± 0.86 and 0.52 mg/mL ± 0.11, respectively, during the PVP. Mean LNRs were 5.87 ± 3.36 versus 2.56 ± 1.10 and 2.29 ± 0.87, respectively, during the AP and 2.01 ± 1.33 versus 0.96 ± 0.16 and 0.93 ± 0.26, respectively, during the PVP. The mean ICD for the HH group (1.37 mg/mL ± 0.84) was significantly higher than the mean ICDs for the HCC-cirrhosis (0.33 mg/mL ± 0.29) (P < .001) and HCC-no cirrhosis (0.82 mg/mL ± 0.99) (P = .03) groups. The combination of NIC and LNR had higher sensitivity and specificity compared with those of conventional qualitative CT image analysis during individual and combined phases. CONCLUSION: Use of spectral CT with fast tube voltage switching may increase the sensitivity for differentiating small hemangiomas from small HCCs in two-phase scanning.
