[Long-pulsed frequency-doubled neodymium:YAG laser in treatment of superficial varicose veins. Initial clinical experiences].

Many different therapeutic approaches are employed to treat small vessels on the leg. In recent years a variety of lasers (argon, Neodymium: YAG and dye lasers) have been used as well as sclerotherapy, cryosurgery and electrosurgery. None of these lasers are entirely satisfactory, and there are a number of side effects. Because of its special physical characteristics, the newly developed long-pulsed frequency-doubled neodymium: YAG laser has clear advantages in the treatment of vascular lesions compared to other laser systems. These include: no vessel rupture compared to dye laser, no epidermal lesions compared to argon laser. In clinical tests it shows a high rate of effectiveness with minimal side effects.

[The neodymium YAG laser: its application in dermatology].

The neodymium:yttrium-aluminium-garnet-(Nd:YAG) laser is one of the most versatile and interesting lasers in dermatological laser medicine. Almost no other laser has such a wide spectrum of applications. Depending on wave length (1064 nm, frequency-doubled 532 nm) and mode (continuous, Q-switched, long-pulsed), benign pigmented lesions (tattoos, traumatic tattoos, naevus of Ota, cafe-au-lait-macules, lentigines) and vascular lesions (hemangiomas, portwine stains, essential teleangiectasias, angiomas) can be treated. Additionally this laser has been occasionally used to remove Kaposi sarcomas and epithelial skin tumors.

Soft tissue telangiectatic osteosarcoma in a young patient: imaging and immunostains.

Telangiectatic osteosarcoma of the soft tissue is rare and generally affects adults older than 50 years of age. We present the case of a 17-year-old male who developed a mass in the right thigh. The CT and MRI findings suggested a malignant hemorrhagic tumor without discernable osteoid matrix. Differential diagnosis included various hemorrhagic mesenchymal tumors. Histology revealed large multiple cysts lined with septae and filled with numerous giant cells, pleomorphic spindle cells, and occasionally an osteoid-like substance. Immunostaining for osteocalcin was positive in the cytoplasm of both stromal mononucleate and multinucleate giant cells. Surgery and adjuvant chemotherapy were applied and the patient survives to the time of writing after 30 months of follow-up without recurrence or metastasis.

Five-year evolution of a telangiectatic osteosarcoma initially managed as an aneurysmal bone cyst.

We present the clinical, radiographic, and pathologic features of a telangiectatic osteosarcoma (TOS) of the right femoral neck in a 20-year-old man which was initially diagnosed and managed as an aneurysmal bone cyst (ABC). The lesion recurred twice. At the second recurrence TOS was diagnosed. The first local recurrence was recognized 4 years 8 months after the first operation. The clinical diagnosis for the recurrent lesion was recurrent ABC, and curettage and bone graft with internal fixation were performed. The second local recurrence was observed 8 months after the second surgery. The right lesser trochanter appeared destroyed on the radiograph, and a large medial soft tissue mass was demonstrated by computed tomography. The patient underwent wide resection of the tumor with prosthetic replacement of the right proximal femur. The histologic section for this lesion showed a blood-filled cystic lesion, and its wall contained sarcomatous cells with atypical mitoses and tumor osteoid. The histologic diagnosis for the second recurrent lesion was high-grade TOS. The retrospective review of the histologic section for the primary lesion showed similar features to ABC except for a few bizarre cells without mitosis in the tissue of cystic wall. The patient demonstrates no evidence of disease 13 months after the last surgery without adjuvant therapy (he declined chemotherapy).

Soft tissue osteosarcoma with telangiectatic features: MR imaging findings in two cases.

Extraskeletal osteosarcomas are rare tumors, and the telangiectatic variety is the least common histological variety in this group. This report describes the clinical and MR imaging findings in two cases arising in the pretibial soft tissues. Both tumors demonstrated marked inhomogeneity with T2-weighted spin echo and STIR sequences. One of the tumors revealed numerous fluid levels within the lesion. A review of the MRI features of these tumors is provided. Osteosarcoma with telangiectatic features should be considered in the differential diagnosis of a soft tissue mass with fluid-fluid levels in patients 40 years of age or older.

Intense pulsed light treatment of 1,000 consecutive patients with facial vascular marks.

BACKGROUND: Facial teleangectasias or vascular marks often represent a very cosmetically detracting problem for the affected patient, who tries to cover the lesions by camouflage strategies. This study describes the response of these vascular lesions after an intense pulsed light source was used on 1,000 consecutive patients. METHODS: Between October 1998 and April 2005, 1,000 consecutive patients with various skin types (Fitzpatrick I to IV) were treated with Photoderm VL. The average age of the patients was 47.1 years. These patients were subjected to a mean of 2.16 treatments (range, 1-9), then followed up 48 h, 72 h, 1 week, 3 weeks, and 1 month after each treatment. All the patients were followed up 2 months after the last treatment, and the percentage of clearance was assessed by comparison of pre- and posttreatment photographs. The patients also answered a questionnaire in which they expressed personal satisfaction. The final physicians-nurse evaluation also was recorded on the same form. RESULTS: Most of the patients (89.70%) experienced a clearance of 75% to 100%. The results appear to be correlated with operator experience, but not with lesion size, age, or skin type. Minimal adverse side effects occurred for 14.6% of the patients, but only for 6.76% of the treatments. CONCLUSION: The intense pulsed light source Photoderm VL can be considered a fast, safe, and effective treatment for facial teleangectasias or vascular marks.

Symptomatic unilateral dolicho-ectasia of the intracranial arteries in a child.

Dolicho-ectasia of the left posterior cerebral artery and internal carotid artery in a 5-year-old boy is reported. There was compression of the brainstem, the mammillary bodies and the optic tract. The value of MR angiography in the diagnosis of this vascular anomaly is demonstrated. Dolicho-ectasia of more than one cerebral artery in a child is extremely rare.

[Vitrectomy in advanced Coats disease].

BACKGROUND: Coats disease is a retinal vasculopathy of unknown cause. Untreated cases usually lead to an exudative retinal detachment and rubeosis iridis with secondary glaucoma. Photocoagulation and/or cryotherapy are generally the first interventions in treating the disease. Pars plana vitrectomy may be indicated in cases of vitreous hemorrhage or retinal detachment. METHODS: We performed pars plana vitrectomy in 9 eyes with Coats disease between 1992 and 1999. A retinal detachment was present in 3 cases, and three showed a vitreous hemorrhage. In two cases surgery was indicated because of paramacular localization of the pathological vessels with associated exudations. RESULTS: The two cases with paramacular involvement showed improvement in visual acuity of eight lines. In the remaining cases visual acuity remained within two lines compared to the initial visual acuity. All eyes except one could be saved. CONCLUSION: Pars plana vitrectomy is a useful option in treating advanced Coats disease, especially in cases associated with vitreous hemorrhage or retinal traction.

Coats-like lesions in Usher syndrome type II.

BACKGROUND: An unusual case of Usher syndrome type II associated with bilateral Coats-like exudative retinopathy is described. METHODS: A 14-year-old boy with congenital sensorineural deafness and normal vestibular functions presented with a recent history of night blindness. He was followed for 3 years with fundus photography, intravenous fluorescein angiography, electroretinography and audiometric testings. His parents refused any form of treatment. RESULTS: Fundoscopy showed bilateral retinitis pigmentosa and a single focus of subretinal exudation and overlying telangiectatic retinal vessels inferotemporal to the vascular arcade in the right eye. He had bilateral mild macular edema. A year later, a similar lesion developed inferotemporally in the left fundus. Electroretinography responses, particularly the rod-mediated signals, were significantly reduced. Audiometric studies documented hearing loss in high frequencies. His visual acuity declined from 20/40 to 20/80 RE and from 20/80 to 20/100 LE during follow-up. No new lesions developed. CONCLUSIONS: Coats-type exudative lesions may develop in patients with Usher syndrome type II. Although left untreated, only a minimal increase in exudation occurred over 3 years.

Macular hole formation associated with idiopathic parafoveal telangiectasia.

BACKGROUND: To report the occurrence of a full thickness macular hole in association with idiopathic parafoveal telangiectasia. METHODS: Observational case report. RESULTS: A 60-year-old female with a history of bilateral idiopathic parafoveal telangiectasia presented with acute complaints of decreased vision and metamorphopsia in her right eye. The patient's retinal examination was significant for idiopathic parafoveal telangiectasia bilaterally, and a new, full-thickness macular hole in the right eye which was confirmed by optical coherence tomography. CONCLUSIONS: Full-thickness macular hole formation may occur in conjunction with idiopathic parafoveal telangiectasia, which has not been reported to date.

Coats' disease and bilateral cataract in a child with Turner syndrome: a case report.

PURPOSE: To report the first case in which Coats' disease was observed with infantile cataract in a girl with Turner syndrome (TS). MATERIALS AND METHODS: We examined a 4-year-old female infant with TS who was referred with a diagnosis of leukocoria in the left eye. RESULTS AND DISCUSSION: Examination under anaesthesia revealed a bilateral punctate cataract and left eye fundus showed vascular retinal abnormalities typical of Coats' disease. Cryotherapy was performed on the telangiectatic vessels and the child was followed up for a period of 12 months. Despite cryotherapy resulting in regression of the peripheral exudates, an exudative maculopathy persisted with poor visual outcome. We suggest that Coats' disease should be considered as a rare ocular manifestation in TS.

Multiple telangiectatic focal nodular hyperplasia: vascular abnormalities.

The aim of this study was to look for vascular abnormalities in the liver of patients with multiple telangiectatic focal nodular hyperplasia. Four patients, all women on oral contraceptives, were included in this study. In none of the cases was the diagnosis of multiple telangiectatic focal nodular hyperplasia made preoperatively. In the nodules, the pathological aspect was quite characteristic with dilated sinusoidal areas surrounding compact areas. Compact areas comprised portal tract-like structures with vessels, mainly thickened arteries, usually amidst an inflammatory reaction. A ductular reaction of varied intensity was present in three cases. The non-nodular liver was grossly normal. However, in rare areas, there were obvious or minor vascular abnormalities looking like minimal abnormalities seen inside telangiectatic nodules. These results seem to support the concept that multiple telangiectatic focal nodular hyperplasia is a non-specific reaction to focal ischemia induced by various mechanisms such as hepatic vein thrombosis induced, perhaps, by oral contraceptives.

Cutis marmorata telangiectatica congenita with gangrenous ulceration and hypovolaemic shock.

UNLABELLED: Cutis marmorata telangiectatica congenita (CMTC) is an uncommon sporadic congenital vascular anomaly characterised by persistent cutis marmorata, telangiectasia, and phlebectasia. The disease usually has a benign clinical course and over 50% of cases recover spontaneously without specific treatment. The occurrence of life-threatening complications in CMTC is rare. CONCLUSION: We report a neonate with life-threatening cutis marmorata telangiectatica congenita which was complicated by gangrenous ulceration, bleeding episodes, and hypovolaemic shock.
