Cavernous hemangiomas are not true vascular tumors, but rather are slow-flow venous malformations (VMs). They are present at birth as nonproliferating vascular birthmarks composed of anomalous ectatic venous channels. VMs have often been incorrectly called cavernous hemangiomas and cavernous angiomas. These terms have for a long time lead to confusion with the more common proliferating or true hemangioma of infancy. VM has been reported to arise at all sites including skin and subcutaneous layers of the head and neck, face, extremities, liver, gastrointestinal tract, and even the thymus...

PURPOSE: Sturge-Weber syndrome (SWS) is a neurocutaneous disorder characterized by a facial port-wine stain, a glaucoma, and a leptomeningeal angioma. Epilepsy occurs in more than 75% of affected children, and seizures occurring in the first year of life are associated with a poor neurological prognosis. The aim of this study was to identify possible predictive markers of epilepsy on electroencephalogram (EEG) performed prior to seizure onset in children with SWS. METHODS: This study included children with a diagnosis of SWS who had an EEG performed prior to seizure onset...

Radiotherapy is a useful modality for the treatment of brain tumors, but may induce brain degeneration, tumor formation, and vasculopathy in the irradiated field. We describe a rare case of a pediatric patient who presented multiple different types of vascular events consecutively in the irradiated field including lacunar stroke because of occlusion of perforating artery, intraventricular hemorrhage from cavernoma, and subarachnoid hemorrhage because of the rupture of fusiform aneurysm, 6 years after radiotherapy against pilocytic astrocytoma...

BACKGROUND: Brain cavernous angiomas with symptomatic hemorrhage (CASH) are uncommon but exact a heavy burden of neurological disability from recurrent bleeding, for which there is no proven therapy. Candidate drugs to stabilize the CASH lesion and prevent rebleeding will ultimately require testing of safety and efficacy in multisite clinical trials. Much progress has been made in understanding the epidemiology of CASH, and novel biomarkers have been linked to the biological mechanisms and clinical activity in lesions...

Intracranial cavernous angiomas (CAs) are hamartomatous vascular malformations consisting of thin-walled vascular channels located within the brain, but typically lacking intervening neural parenchyma, large feeding arteries, or draining veins. The CAs occurring in the ventricular system are rare, with an incidence of 2.5% to 10.3% of the intracranial CAs, and those arising from the trigone of the lateral ventricle are even rarer. Till now, there are <20 patients with trigonal CAs have been reported in the English literature...

This case report describes a novel presentation of littoral cell angioma (LCA) and lymphatic malformations involving the omentum and mesentery. To our knowledge, these 2 entities have not been reported in the same patient. A 1-month term infant male presented with chylous ascites. During his workup, imaging detected splenic nodules. Biopsies revealed that the nodules were LCA and the chylous ascites was secondary to microscopic mesenteric and omental lymphatic malformations. Evaluation for a secondary malignancy, an underlying immunologic defect, and genetic causes were unrevealing...

Vascular tumors in infants present a diagnostic and treatment dilemma for both clinicians and pathologists. Infantile hemangioma, the most common vascular tumor in infants, can be confused for other less common vascular tumors in infants. Correct and timely diagnosis is important, as some vascular tumors can be associated with life-threatening coagulopathy. We present the cases of 5 vascular tumors that have clinical and histologic overlap: infantile hemangioma, pyogenic granuloma, noninvoluting congenital hemangioma, tufted angioma, and kaposiform hemangioendothelioma...

The majority of spinal cavernous angiomas (CAs) originate from the vertebral bodies with or without epidural space extension. Solitary epidural CAs are rare. In the present study, we retrospectively reviewed the records of 12 patients who underwent microsurgery for solitary spinal epidural CAs. All patients had performed pre- and postoperative magnetic resonance imaging. The patients were 7 females and 5 males with the mean age of 52.1 years. Two tumors were located in the cervicothoracic spine, nine in the thoracic spine and one in the lumbar spine, respectively...

Purpose: Sturge-Weber syndrome (SWS) is a neurocutaneous disorder characterized by facial cutaneous venous dilatation (port-wine stain), leptomeningeal angioma, and ocular abnormalities. Here we report a case of SWS who experienced acute primary angle-closure in the same side of the nevus flammeus. Observations: A 64-years-old female patient with SWS port wine stain on the left side of her face was referred to our ER for acute primary angle-closure (PAC). The IOP was 64 mmHg in the left eye (12 mmHg in OD) and the visual acuity was 20/100...

OBJECTIVE: To assess sublingual microcirculation in cirrhotic patients and its relationship to spider angiomas, complications, and outcome. METHODS: Thirty-one cirrhotic patients were prospectively compared to 31 matched controls. Sublingual microcirculation was evaluated by videomicroscopy. We specifically looked for capillaries with increased red blood cell velocity, which was defined as a velocity higher than the percentile 100th of controls. RESULTS: Compared to controls, cirrhotic patients showed decreased total and perfused vascular density (14...

Cherry angioma (CA) is one of the most common types of acquired vascular proliferation of the skin [1]. The most commonly recommended treatment modalities in the past have been electrosurgery and cryotherapy. These treatment modalities usually show acceptable cosmetic results with minimal discomfort [2,3]. However, there is no study in the literature that compares these treatment modalities. Herein, we plan to assess the efficacy and safety of cryotherapy versus electrosurgery in the treatment of cherry angioma...

It has been claimed that hyperestrogenism occurs in hypertrophic osteoarthropathy (HOA), but not in simple clubbing. However, one of our patients had simple clubbing and hyperestrogenism. We therefore measured estrogens, androgens, sex hormone-binding globulin (SHBG), and gonadotropins in five patients with HOA and in 18 patients with simple clubbing. Of the patients with HOA, 80% had a high urinary estriol concentration. In their serum, 80% had high estrone, 0% high estradiol, and 40% high SHBG. Of the patients with simple clubbing, 89% had a high urinary estriol concentration...

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vascular proliferative disorder mainly located in the periauricular region. The etiopathogenesis of ALHE is unknown, and it is still controversial as to whether the entity represents a benign vascular neoplasm or an inflammatory process. Aim: Recently, the intracytoplasmic staining pattern of Wilms tumor 1 (WT1) on immunohistochemistry has highlighted true vascular neoplasms, such as microvenular hemangioma, tufted angioma, and spindle cell hemangioma, which has made it helpful to distinguish ALHE from vascular malformations, as there is a negative staining pattern in the other entities...

BACKGROUND: Angioma serpiginosum (AS) is a rare vascular abnormality consisting of proliferation and dilation of superficial blood vessels in the skin. AS typically presents in the first 2 decades of life and remains stable with time. CASE SUMMARY: We report the case of a 13-year-old female with an acquired, recurrent erythematous lesion with serpiginous borders on her left upper arm. Over several years, the lesion reappeared then disappeared 12 to 15 times. At one point, she developed a tender red nodule within the lesion; consequently, a biopsy was taken, revealing dilated telangiectatic vessels in the dermal papillae with mild, focal extravasation of erythrocytes...

BACKGROUND Invasive mucinous adenocarcinoma (IMA) is a rare variant of adenocarcinoma of the lung. It frequently shows KRAS mutations, while ALK rearrangement is exceedingly rare. We present a case of ALK-rearranged IMA of the lung presenting with an unusual pattern of brain metastases, radiologically mimicking a cavernous angioma. CASE REPORT A 44-year-old non-smoker female was first diagnosed with lung right lower lobe IMA with ALK rearrangement. Five years after surgery followed by chemotherapy, she developed a sudden onset headache...

Inducing therapeutic angiogenesis to effectively form hierarchical, non-leaky networks of perfused vessels in tissue engineering applications and ischemic disease remains an unmet challenge, despite extensive research and multiple clinical trials. Here, we use a previously-developed, multi-scale, computational systems pharmacology model of human peripheral artery disease to screen a diverse array of promising pro-angiogenic strategies, including gene therapy, biomaterials, and antibodies. Our previously-validated model explicitly accounts for VEGF immobilization, Neuropilin-1 binding, and weak activation of VEGF receptor 2 (VEGFR2) by the "VEGFxxxb " isoforms...
