Rare vascular proliferations of the oral mucosa (original) (raw)

Spindle-cell hemangioendothelioma of the oral cavity. A case report

Journal of Oral Pathology & Medicine, 1995

We describe a vascular tumor classified as SCH by histological criteria that was foutid in the mandibular-buccal fold of a 12-year-old girl. Microscopically, the lesion consisted of thin-walled cavernous spaces containing thrombi and phleboliths, and cellular areas composed of spindle-shaped, epithelioid and vacuolated cells. Immunohistochemically, the endothelial vascular lining was highly reactive with HAM56 antibody, while variable reactivity was observed for factor VIIIassociated antigen. All cell types were positive for vimentin and anti-PCNA stained less than 3% of the tumor cells. This is the first report of SCH in the oral cavity.

Atypical Presentation of Capillary Hemangioma in Oral Cavity- A Case Report

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2015

Capillary Haemangioma is a benign vascular tumour characterized by proliferation of blood vessels that are primarily reported to be a developmental hamartomatous lesion of infancy and childhood. Pyogenic granuloma is a non-neoplastic benign lesion found in the oral cavity having a striking predilection for occurrence in the gingiva. The present case report is an atypical presentation of capillary haemangioma on gingiva which is considered to be extremely rare. The lesion in this case was clinically diagnosed as pyogenic granuloma but histopathologically as capillary haemangioma. These lesions present as a diagnostic dilemma to the clinician and can lead to serious complications if not carefully managed.

Capillary hemangioma as a rare benign tumor of the oral cavity: a case report

Cases Journal, 2009

Introduction: Hemangioma is a relatively common benign proliferation of blood vessels that primarily develops during childhood. Two main forms of hemangioma recognized: capillary and cavernous. The capillary form presents as a flat area consisting of numerous small capillaries. Cavernous hemangioma appears as an elevated lesion of a deep red color, and consists of large dilated sinuses filled with blood. The purpose of the study was to report the case of a capillary hemangioma in a patient and to describe the successful treatment of this case.

Oral Epithelioid Hemangioendothelioma — Unusual Location of a Rare Entity

Journal of Interdisciplinary Medicine, 2017

Introduction:Epithelioid hemangioendothelioma is a rare, locally aggressive vascular tumor, originating from soft tissue, bone, skin, and organs such as the liver or lung, exceptionally located in the oral cavity. Most of the cases of oral epithelioid hemangioendothelioma are asymptomatic, and diagnosis is hampered by the fact that the histological features are somewhat between hemangioma and angiosarcoma, with epithelioid cells, intracytoplasmic vacuoles, low mitotic activity, and (rarely) necrosis. Immunohistochemical analysis is required to rule out carcinoma or other epithelioid vascular neoplasms.Case presentation:We present a rare case of a 59-year-old Caucasian male patient with oral epithelioid hemangioendothelioma for which clinical and cytological diagnosis was difficult, in spite of the patient’s history. The lesion was nonspecific, mimicking ulcerative stomatitis, but histological and immunohistochemical evaluation finally managed to establish the right diagnosis. Subseq...

Epithelioid hemangioendothelioma of the oral cavity: Report of two cases and review of literature

Journal of Oral and Maxillofacial Surgery, 1991

Weiss and Enzinger' introduced the term epithelioid hemangioendothelioma to describe a vascular neoplasm of soft tissue characterized by a proliferation of endothelial cells with an epithelioid morphology. The biologic behavior of the tumor is "borderline" in the sense that it has an indolent course with the potential for recurrence, but rarely metastasizes. The tumor occurs predominantly in the extremities, but less frequently in the head and neck."4 It also has been reported in the lung,'.' liver,*-" and bone."," Three cases have been recently reported in the oral cavity,3.'3,'4 two in the gingiva and one in the palate. This is a report of two additional cases, one of the maxillary palatal gingiva and the second involving the tongue. A review of the previously reported cases is also provided. Report of Cases Case 1 A 45year-old white man presented with a 1.5 x l&cm raised, erythematous, mass of 2 years duration of the right maxillary palatal gingiva between teeth nos. 5 and 6. The clinical impression was pyogenic granuloma (Fig 1). The lesion was excised, but recurred 3 months later. The

Intraoral epithelioid hemangioendothelioma: A case report and review of the literature

Medicina Oral Patología Oral y Cirugia Bucal, 2010

The epithelioid hemangioendothelioma (EH) is an uncommon angiocentric neoplasm of borderline or intermediate malignant potential, between the hemangioma and conventional angiosarcoma. It is characterized by the proliferation of endothelial cells with epithelioid or histiocitóide morphology with vacuolated cytoplasm and occasional eosinophilic spindle cells. Shows potential for local recurrence as well as the ability to metastasize. Rarely affects the oral cavity, it have been described from 1975 until 2008 only 27 oral cases. Morphologically the EHs may be confused with other lesions, from a hemangioma to a squamous cell carcinoma, and thus immunohistochemical analysis is required. This paper reports the clinical and immunohistochemical characteristics of a case of EH in the gingiva of the tooth 35 of a 17 years-old-white-female. We present a review of the clinicopathological and immunohistochemical characteristics of the intraoral epithelioid hemangioendothelioma cases previously reported.

Capillary hemangioma of palatal mucosa

Journal of Indian Society of Periodontology, 2012

The article titled "Oral haemangioma" [1], published in Case Reports in Medicine, has been retracted as it is found to contain a substantial amount of material from the paper "Capillary hemangioma of palatal mucosa, " Bharti Vipin,

Intraoral Epithelioid Hemangioendothelioma: an Intermediate Vascular Tumor-A Case Report

Dental Research Journal, 2010

Vascular neoplasms, other than benign are characterized as intermediate or malignant. They are often enshrouded in controversy, because the same neoplasm could show variability in biologic behavior that may not be correlated with microscopic features. The intermediate grade vascular neoplasm is named as epithelioid hemangioendothelioma (EHE). Epithelioid hemangioendothelioma of the oral cavity has been infrequently reported. To the best of our knowledge, the review of the English literature revealed a total of 30 cases of intraoral EHE reported till today. We report such a rare case in a 20 year old male, presented with a growth in lower anterior lingual gingiva since five months before the diagnosis with a history of similar swelling, twice in the same area. The differential diagnosis and brief review of literature is also discussed in the current article.

Oral intramuscular hemangioma: Report of three cases

Journal of Cutaneous Pathology, 2019

Intramuscular hemangioma represents less than 1% of all hemangiomas. In the head and neck region, it occurs mostly in the masseter, temporalis and sternocleidomastoid muscles. Besides its infiltrative growth pattern and several worrisome histological features, such as increased mitotic activity, plumpness of the nuclei, intraluminal papillary projections or perineural infiltration, the lesion is benign, and complete surgical excision is the preferred treatment for such oral lesions. Herein, we report three rare cases of intramuscular hemangioma in the tongue and lip, discuss the clinical and histological aspects, and review the literature regarding this lesion.

Rare case of spindle cell haemangioma of oral cavity

BMJ Case Reports

Spindle cell haemangioma (SCH) is a slow growing, benign vascular lesion with a preference for the distal extremities. Its occurrence in the oral cavity is rare. Clinically, it presents as solitary or multiple subcutaneous nodules, therefore, it could be considered in the differential diagnosis of benign soft tissue tumours. Microscopically it mimics some malignant vascular tumours and it is necessary to differentiate it from other malignant vascular lesions. We report a case of SCH in anterior mandibular region of a young male in his 20s. Although it is a benign lesion, the reported case displayed extensive areas of muscle infiltration and necrosis. After studying the radiographic findings and considering the absence of cellular atypia, a final diagnosis of SCH was made. Literature survey suggests that this is the eleventh case of SCH reported in oral cavity.
