PURPOSE: To describe the features of choroidal tumors on infrared (IR) imaging and to determine the diagnostic sensitivity and specificity of intratumoral choroidal vascular loops on IR imaging for circumscribed choroidal hemangioma (CCH). METHODS: Infrared and indocyanine green images of CCH, choroidal metastases, and choroidal melanomas were reviewed. The main outcome measure was the presence of intratumoral choroidal vascular loops and tufts on IR images. The secondary outcome measure was the presence of peritumoral vascular expansion on indocyanine green images...

Vascular tumors are among the most common neoplasms in infants and children; 5%-10% of newborns present with or develop lesions within the first 3 months of life. Most are benign infantile hemangiomas that typically regress by 5 years of age; other vascular tumors include congenital tufted angiomas (TAs), kaposiform hemangioendotheliomas (KHEs), and childhood lobular capillary hemangiomas (LCHs). Some of these lesions can become locally invasive and unresponsive to pharmacologic intervention, leading to significant complications...

Mark R Wick
Vascular proliferations in the skin have been thoroughly studied over the past 35 years, and a great deal of knowledge has been accrued regarding their pathobiological features. Dr. Juan Rosai has been a consistent contributor to the literature on this topic throughout most of his career, and this article reviews selected cutaneous endothelial lesions that he helped to characterize. They include histiocytoid-epithelioid hemangioma, targetoid-hobnail hemangioma, acquired tufted hemangioma, glomeruloid hemangioma, spindle cell hemangioma, retiform hemangioendothelioma, and angiosarcoma...

IMPORTANCE: Inhibition of angiogenesis is an effective anticancer strategy because neoplasms require a rich blood supply. Ramucirumab, approved by the US Food and Drug Administration in 2014 to treat gastric adenocarcinomas and non-small cell lung carcinomas, targets vascular endothelial growth factor 2 (VEGFR2). We identified a patient prescribed a regimen of irinotecan hydrochloride, cetuximab, and ramucirumab for metastatic rectal cancer (diagnosed in November 2013 and treated through early January 2015) who developed a new-onset, expanding vascular lesion on his right leg...

Tufted angioma is a rare vascular tumor whose name derives from its histopathological appearance, characterized by tufts of capillaries within the dermis. Its etiology and pathogenesis are uncertain. Tufted angioma typically occurs during infancy or early childhood and displays various clinical patterns. It may present as a subtle stain-like area that later thickens as a large plaque, infiltrated or dusky blue-purple lesion, or as an exophytic, firm, violaceous, cutaneous nodule. Medical treatment is not necessary for tufted angioma, given its benign nature and slow progression...

PURPOSE OF REVIEW: Since 2008, beta-blockers have become first-line treatment for infantile hemangiomas, the most common tumor of infancy. Their role is also being explored in the treatment of other childhood vascular tumors. RECENT FINDINGS: Recent research has demonstrated that propranolol is a more effective and safer treatment for infantile hemangiomas than previous therapeutic options. It is most effective when initiated during the tumor's proliferative phase...

Kasabach-Merritt syndrome (KMS), characterized by thrombocytopenia, may complicate vascular tumors such as kaposiform hemangioendothelioma and tufted angioma. We report on two infants, respectively 2 months and 15 days old at the onset of symptoms, the first of whom presented with a left cervico-occipito-scapular hemangioma with parotid extension, and the second with a vascular tumor located on the left shoulder with fast extension on the left inferior hemithorax and the left arm. Thrombocytopenia (< 20 G/L) was associated in both cases...

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor that may be complicated by Kasabach-Merritt phenomenon (KMP), a profound thrombocytopenia resulting from platelet trapping within a vascular tumor, either KHE or tufted angioma (TA). Typical features also include low fibrinogen and elevated D-dimers. It is well known that KMP is not caused by infantile hemangiomas. Management of vascular tumors complicated by KMP is challenging, and it is common for referral centers to receive patients in critical medical condition after multimodality treatment failure of vascular anomalies...

We report the case of a 2-month-old infant with a single apparently ecchymotic lesion on the shoulder that raised suspicions of abuse. The medicolegal examination concluded that the appearance of the lesion was only mildly suggestive of an ecchymosis. A second, temporally remote examination confirmed this doubt. The evolution of the lesion, notably an increase in its volume, allowed us to rule out a traumatic lesion and was suggestive of a vascular tumor. The histological type of the tumor was a tufted angioma...

Tufted angioma (TA) is a rare benign vascular neoplasm characterized histopathologically by the proliferation of endothelial cells arranged in lobules in the dermis and subcutaneous fat. To date, about 200 cases have been reported, most of which are of Japanese ethnicity. TA predominantly affects children and young adults, developing in 80% of patients younger than 10 years. A white 72-year-old renal transplant recipient presented with 2 asymptomatic dusky red papules on his right leg. The lesions appeared 5 years after the start of immunosuppressive treatment...

Malignant cutaneous vascular tumours are very uncommon in children. As in adults, they are aggressive neoplasms with metastatic potential and a high mortality rate. Some nonmalignant vascular tumours may exhibit a locally aggressive behaviour and some of them can be associated with life-threatening systemic complications such as Kasabach-Merritt syndrome. Early diagnosis of these aggressive neoplasms in children is very important in order to start appropriate therapy as soon as possible, as this can have a significant impact on the prognosis of these patients...

BACKGROUND: Tufted angioma (TA) is a benign cutaneous vascular tumor that most commonly occurs in young children. TAs have rarely been reported in adults and/or arising within port-wine stains (PWS). Kasabach-Merritt phenomenon (KMP) is a life-threatening consumptive coagulopathy hypothesized to occur specifically in young children who develop either a TA or kaposiform hemangioendothelioma. METHODS: Here we present a 52-year-old man with hepatitis C cirrhosis who presented with an extensive, painful vascular tumor involving the right side of his head, neck, and back that initially arose within a PWS...

Tufted angioma is an acquired vascular proliferation with specific histological characteristics. The most common clinical features are erythematous macules. It occurs predominantly in children and young adults, especially in the chest and neck. We report the case of a male patient, 12 years old, with an increased right ear auricle associated with erythematous macules and increased local temperature, referred with a diagnosis of lepromatous leprosy; however, this diagnosis was questioned. Histopathology was consistent with tufted angioma...

UNLABELLED: Tufted angioma, first recognized in Japanese literature as "Angioblastoma of Nagakawa", is a rare benign vascular tumour with a variable clinical presentation. It commonly manifests as a macule, papule or nodule in infancy or childhood in the region of the upper trunk and neck. Here in we report two cases of this rare progressive angioma as lesions of the eyelid in adults. Tufted angioma has a classical "cannon ball" like appearance of vascular tufts on histopathology. Immunohistochemical staining with actin highlights the spindly stromal cells surrounding the capillaries...

The classification system for vascular anomalies now used by experts worldwide comprises two distinct disease entities that differ in their biologic and pathologic features: vascular tumors and vascular malformations. Vascular tumors include infantile and congenital hemangiomas, tufted angiomas, and kaposiform hemangioendotheliomas. Infantile hemangiomas, the most common vascular anomaly, generally have a predetermined life cycle (proliferation and subsequent involution). GLUT-1, a glucose transporter, is a marker for these specific lesions during all phases of development...
