NMC Case Rep J 2022; 9:187-192. [PMID: 35855280 PMCID: PMC9256015 DOI: 10.2176/jns-nmc.2022-0079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 04/12/2022] [Indexed: 11/20/2022] Open
Abstract
Tufted angioma is a benign vascular tumor in which immature endothelial and pericyte cells and lymphatic vascular endothelium grow. It manifests as a flat, painful erythema that gradually expands mainly on the trunk and extremities. Although tufted angiomas can also occur in other areas of the body and may be more locally invasive, they rarely occur intracranially. A 63-year-old man underwent magnetic resonance imaging (MRI) for a brain check-up 8 years before his visit to our institute, which detected a mass lesion with surrounding cerebral edema in the left frontal lobe. The patient was followed up with annual MRI analysis, which indicated slow tumor growth and gradual development of peritumoral edema. The tumor was treated by gross-total resection. Histological analysis showed a slightly dilated microvascular core surrounded by many capillary aggregates in the brain parenchyma. Immunohistochemical findings indicated that the vascular endothelial cells were positive for CD34 and Brahma-related gene-1 and were surrounded by smooth muscle actin-positive pericytes. These findings were consistent with tufted angioma. Intracranial tufted angioma is uncommon, but it should be considered in the differential diagnosis for intracranial tumorous lesions. Long-term follow-up is necessary to unravel the natural history of the disease.

Abstract
Tufted Angiomas, also known as angioblastomas/Angioblastoma of Nagakawa, are rare vascular neoplasms of both sexes localised to the skin and subcutaneous tissues with the upper trunk and neck being the most common sites. They are more common in children but a few cases in juveniles and adults have been reported. Typically, Tufted Angioma remains stable or can show rarely a spontaneous regression. This article wants to evaluate the efficacy of current treatment modalities for tufted angioma (TA). A review was performed using PubMed database (Medline) for clinical studies. We report our case, a 29-year-old female who presented with a second finger of the left hand, painful, slowly progressive, firm swelling diagnosed as Tufted Angioma on histopathology and immunohistochemistry after complete surgical excision.

Abstract
The features of tufted angioma (Nakagawa), Kaposiform infantile hemangioendotheli oma, and proliferative cutaneous angiomatosis are reviewed. Tufted angioma, which usually appears before the age of ten years, is a large, poorly demarcated, macular, cutaneous and subcutaneous lesion most commonly located on the neck or trunk. Histologically, there is a "cannon ball" pattern of concentrically whorled lobules and tufts of endothelial and perithelial cells. Tufted angioma is difficult to excise and usually persists throughout life but causes no serious symptoms. Kaposiform infantile heman gioendothelioma is a rare, aggressive vascular tumor of the deep soft tissues, bone, and skin that presents during the first year of life and is often complicated by Kasabach- Merritt syndrome. Histologically, there is a Kaposiform pattern, but some cells may be arranged in nodules and tufts indistinguishable from tufted angioma. Kaposiform infantile hemangioendothelioma responds to interferon therapy. On the basis of the few cases so far recognized, proliferative cutaneous angiomatosis is a large, diffuse, mainly superficial angioma that grows insidiously and is biopsied in the second or third decade of life. Histologically, there are irregular, interconnecting cords and sheets of endothelial cells that form anastomosing spaces. Extravasated red cells and endothe lial hemosiderosis are prominent. The superficial location, older age, and the distinctive histology suggest that proliferative cutaneous angiomatosis differs from Kaposiform infantile hemangioendothelioma.

Abstract
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, infi ltrated or dusky
blue-purple lesion, or as an exophytic, fi rm, violaceous, cutaneous nodule. Medical
treatment is not necessary for tufted angioma, given its benign nature and slow
progression. Only clinical follow-up is therefore recommended.

Abstract
Vascular anomalies in children and adolescents are the most common soft tissue lesions and include reactive, malformative, and neoplastic tumefactions, with a full spectrum of benign, intermediate, and malignant neoplasms. These lesions are diagnostically challenging because of morphologic complexity and recent changes in classification systems, some of which are based on clinical features and others on pathologic findings. In recent decades, there have been significant advances in clinical diagnosis, development of new therapies, and a better understanding of the genetic aspects of vascular biology and syndromes that include unusual vascular proliferations. Most vascular lesions in children and adolescents are benign, although the intermediate locally aggressive and intermediate rarely metastasizing neoplasms are important to distinguish from benign and malignant mimics. Morphologic recognition of a vasoproliferative lesion is straightforward in most instances, and conventional morphology remains the cornerstone for a specific diagnosis. However, pathologic examination is enhanced by adjunctive techniques, especially immunohistochemistry to characterize the type of vessels involved. Multifocality may cause some uncertainty regarding the assignment of "benign" or "malignant." However, increased interest in vascular anomalies, clinical expertise, and imaging technology have contributed greatly to our understanding of these disorders to the extent that in most vascular malformations and in many tumors, a diagnosis is made clinically and biopsy is not required for diagnosis. The importance of close collaboration between the clinical team and the pathologist cannot be overemphasized. For some lesions, a diagnosis is not possible from evaluation of histopathology alone, and in a subset of these, a specific diagnosis may not be possible even after all assembled data have been reviewed. In such instances, a consensus diagnosis in conjunction with clinical colleagues guides therapy. The purpose of this review is to delineate the clinicopathologic features of vascular lesions in children and adolescents with an emphasis on their unique aspects, use of diagnostic adjuncts, and differential diagnosis.

Abstract
O Angioma em tufo é considerado um raro tumor vascular cutâneo adquirido. Caracteriza-se por máculas purpúrico-violáceas, dolorosas que podem evoluir para placas com pápulas angiomatosas. Tem natureza benigna, mas o envolvimento extenso é comum, gerando alteração funcional do membro afetado em caso de dor. Os autores relatam um caso de angioma em tufo associado à síndrome dolorosa miofascial, em que o elemento predisponente foi a presença deste tumor desde a infância. A dor local prejudicou a utilização da musculatura e possibilitou o surgimento da síndrome relatada. A realização de bloqueio anestésico de pontos-gatilhos no membro afetado, levou à melhora total dos sintomas.

Abstract
Pediatric vascular tumors and malformations, comprising a broad category of lesions often referred to as vascular anomalies, are a heterogenous group of clinicopathologically distinct entities. Pathologists, clinicians, and radiologists have traditionally lumped these lesions under the generic term, hemangioma, sometimes qualified by modifiers, such as capillary or cavernous. Advances in understanding underlying pathogenetic mechanisms support more specific classification and more specifically targeted therapies. Multidisciplinary consensus has moved toward a biologically based classification system and therapeutic approach for dealing with these lesions. This content focuses on the histologic, immunophenotypical, and clinical features that distinguish the major types of vascular tumors and malformations presenting in infancy and childhood. Pathogenic mechanisms are also briefly reviewed.

Abstract
Tufted angioma is a rare cutaneous angiomatous proliferation named because of its characteristic histologic pattern of grouped dermal capillary tufts. Lesions usually begin in infancy or early childhood but rarely are congenital. Clinical manifestations are dull red coalescent papules and plaques, most commonly located on the neck, shoulders, and upper back, and can sometimes be tender. Although transformation to malignancy has not been described, tufted angiomas do not tend to regress. Effective treatments reported in the literature are scarce. We report an adult case of tufted angioma, with unusual presentation as annular plaques, which was alleviated after treatment with intense pulsed light in terms of both cosmetics and discomfort.

Abstract
Vascular tumors of infancy and childhood represent a number of clinicopathologically distinct entities for which precise histopathological diagnosis is often essential in determining effective therapeutic approach. Unfortunately, pathologists and clinicians alike have traditionally tended to lump these tumors, in addition to small vessel vascular malformations, under overly generic terms like capillary hemangioma that do little, if anything, to guide proper clinical management. In the last decade this nosologic oversimplification has begun to wane as important new diagnostic tools and better understanding of etiology have evolved, facilitated by international recognition of the need for a multidisciplinary approach in dealing with these perplexing and often clinically devastating lesions. This article provides a brief historical perspective on this progress, and then focuses on the current clinical, histological, and immunophenotypical features that distinguish the major types of vascular tumors of infancy and childhood, also reviewing new evidence regarding their mechanisms of pathogenesis.

Abstract
Increased understanding of the mechanisms of angiogenesis and lymphangiogenesis has provided a glimpse at some of the molecules involved in the pathophysiology of hemangiomas and vascular malformations. This review focuses on recent advances in our understanding of the mechanisms of angiogenesis/lymphangiogenesis and the differentiation of arterial, venous, and lymphatic vessels. We integrate this knowledge with new data obtained from genetic studies in humans, which have revealed a number of heretofore-unsuspected candidates involved in the development of familial vascular anomalies. We present a common infantile vascular tumor, hemangioma, and then focus on hereditary familial vascular and lymphatic malformations. We also summarize transgenic mouse models for some of these malformations. It seems reasonable to believe that novel therapeutic strategies will soon emerge for the treatment of hemangiomas and vascular malformations.

Abstract
Tufted angioma is a rare benign vascular lesion of unknown etiology which mainly affects children under 5 years. It is characterized by nodules or tufts of capillary-sized vessels in the dermis. Here we report the second familial occurrence of tufted angioma, with a mode of inheritance compatible with a monogenic autosomal dominant trait with reduced penetrance. A preliminary investigation was performed to exclude association between the predisposition and certain candidate genes including KDR (kinase insert domain receptor), TEK (TEK tyrosine kinase endothelial), ACVRL1 (activin receptor-like kinase 1), ENG (endoglin) and FLT4 (fms-like tyrosine kinase 4). KDR, ENG and FLT4 were all compatible with linkage, with haplotypes being shared between three affected individuals and the one obligate carrier available for testing. TEK and ACVRL1 could essentially be excluded. Finally, we provide definitive evidence for the existence of both blood and lymphatic vascular elements in the lesion.

Abstract
We describe two patients with acquired tufted angioma, a unique vascular lesion not previously reported in the oral mucosa. In one patient, the lesion manifested as a purple-red papule and, in the other, as a blue submucosal swelling. Both lesions were non-painful and neither was associated with a history of trauma. The histopathological features consisted of scattered, irregularly shaped tufts, primarily composed of poorly formed capillary spaces and slit-like vascular channels. Capillary spaces were often closely packed, producing solid areas which stained for smooth muscle actin. Staining for factor VIII-related antigen was positive only within endothelial cells lining well-formed vascular channels. Both lesions were treated by excision; short-term follow-up of one patient revealed no evidence of recurrence. Similarities between this and other vascular processes may have resulted in misdiagnosis of this lesion in the past. The clinical significance of acquired tufted angioma in the oral mucosa is not known.

Abstract
This second part of our review about vascular proliferations summarizes the clinicopathologic features of the cutaneous vascular hyperplasias and benign neoplasms. Hyperplasias comprise a heterogeneous group of vascular proliferations that eventually show a tendency to regression. Angiolymphoid hyperplasia with eosinophilia is included within the group of hyperplasias because of its historical denomination and its reactive nature, probably as a consequence of an arteriovenous shunt, although usually the lesions do not regress. Pyogenic granuloma, bacillary angiomatosis, intravascular papillary endothelial hyperplasia, and pseudo-Kaposi's sarcoma qualify as vascular hyperplasias because they regress when the stimulus that initiated them is removed. Benign neoplasms form a large group of hemangiomas with distinctive clinicopathologic characteristics, although some of them are of recent description and may produce diagnostic difficulties. We classified cutaneous benign vascular neoplasms according to their cell lineage of differentiation, for example, endothelial, glomus cell, and pericytic differentiation. Subsequent categories are established according to the size of the involved vessels (capillaries, venules and arterioles, or veins and arteries) or the nature of the proliferating vessels (blood or lymphatic vessels). Capillary and cavernous hemangiomas have been the terms classically used to name the most common variants of benign vascular neoplasms (i.e., infantile hemangiomas), but they are not the most appropriate denominations for these lesions. First, these names are not contrasting terms. Furthermore, most of the socalled "cavernous" hemangiomas are not hemangiomas (neoplasms) at all, but venous malformations. The most important conceptual issue is that, at any point in time, a particular hemangioma has its own histopathologic pattern throughout the depth of the lesion. For these reasons, we classified hemangiomas into superficial and deep categories. Some of the lesions reviewed have been recently described in the literature, and they may histopathologically mimic lesions of Kaposi's sarcoma; these include targetoid hemosiderotic hemangioma, microvenular hemangioma, tufted hemangioma, glomeruloid hemangioma, kaposiform hemangioendothelioma, spindle-cell hemangioendothelioma, and benign lymphangioendothelioma. In each of these lesions, we update and emphasize those clinical and histopathologic features that are helpful for differential diagnosis with lesions of authentic Kaposi's sarcoma in any of its three stages of development (patch, plaque, or nodule).

Abstract
We describe 2 patients with tufted angioma (angioblastoma of Nakagawa) which regressed spontaneously. Both patients had a solitary but large lesion on the trunk. The 1st patient, a 3-month-old girl, presented with a 6-cm plaque which began to regress 2 years later. It regressed completely over 1 year and had not recurred after a further 6-year follow-up. The other patient, a 3-month-old boy, presented with a 12-cm mass of coalescent angiomatous papules which slowly regressed over 3-years, while small new lesions appeared in the adjacent contiguous skin. Eventually, gradual and near complete regression was observed after 8 years. The histology in both cases was typical, but bore some resemblance to the recently described kaposiform hemangioendothelioma, lobular capillary hemangioma and spindle cell hemangioendothelioma.
