Spindle Cell Hemangioma of Lower Lip: The Fourth Case Report with Review of Literature

Background

Spindle cell hemangioma previously known as spindle cell hemangioendothelioma is a benign vascular tumour with rare presentation in head and neck. Presentation in lip is even rarer with three cases reported previously.

Method

This report describes a case of spindle cell hemangioma presented as an asymptomatic growth on lower lip of a 32-year-old male. Clinicopathological characterization of this case along with previously reported 15 cases of spindle cell hemangioma of head and neck were conducted.

Result

Microscopic evaluation shows a well-circumscribed vascular neoplasm of spindled and epithelioid endothelial cells. Large ectatic thin-walled vascular spaces were seen engorged with RBCs. The neoplasm was CD31 positive. Slight predilection for female gender and young age were observed. Minimal possibility of recurrence was also observed.

Conclusion

Spindle cell hemangioma needs to be considered in the differential diagnosis of vascular tumours of head and neck to avoid misdiagnosis of aggressive vascular neoplasms.

Rare case of spindle cell haemangioma of oral cavity

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.

Spindle cell hemangioma in the infratemporal fossa: A unique case report

•

Spindle cell hemangioma (SCH) is a rare vascular tumor that was considered to be intermediate -or low-grade malignancy, with biological behavior between a hemangioma and angiosarcoma.

•

The SCH is commonly found in the distal extremities. So far, only 16 cases have been described in the head and neck area. No previous case has been described in the infratemporal fossa.

•

SCH shows a proliferation of spindle cells composed of endothelial cells, pericytes and fibroblasts between dilated vascular spaces and immunoreactivity to endothelial markers.

Introduction

Spindle cell hemangioma (SCH) is a rare vascular tumor which was first described in 1986. It affects mostly the distal extremities. The head and neck are rarely involved. This article reports the first case of SCH in the infratemporal fossa.

Presentation of case

A 41-year-old woman presented with an 8-month history of right cheek swelling. Facial CT scan and MRI showed an intensely and heterogeneously enhancing tumor of the infratemporal fossa suggesting an angiomatous neoplasm. The mass was excised surgically through an anterior maxillary approach. The histopathological and immunohistochemistry analysis revealed a SCH.

Conclusion

This case report presents a unique presentation of a Spindle cell hemangioma in an unexpected location of the head and neck region. it underlines the importance for clinicians and pathologists to consider the Spindle cell hemangioma as a possible etiological diagnosis of infratemporal fossa tumors.

Spindle Cell Hemangioma in the Mucosa of the Upper Lip: A Case Report and Review of the Literature

Spindle cell hemangioma (SCH) is a unique benign vascular lesion. We present a case of SCH in the upper lip of a 41-year-old woman. A submucosal nodular mass 30 × 20 mm in size was observed in the left upper lip. The mass developed 5 years earlier and enlarged after repeated ethanol injections. The mass was elastic firm, mobile, bluish in color, and well demarcated in magnetic resonance imaging. Under the clinical diagnosis of hemangioma, surgical excision was performed under local anesthesia. Microscopically, the lesion was composed of irregular cavernous spaces and multiple solid cellular areas. Cavernous spaces were filled with a mix of erythrocytes and organizing thrombi. The solid areas showed proliferation of spindle-shaped cells arranged haphazardly or in short interlacing fascicles. Immunohistochemically, most cells strongly reacted with vimentin. CD31, CD34, factor VIII, smooth muscle actin, and Wilms tumor-1 reacted with endothelial cells lining the cavernous spaces. The cells within solid areas consisted of mixed cell population with variable reaction for the markers except for factor VIII. From these findings, the diagnosis of SCH was made. Two years after surgery, no recurrence was noted. A review of SCH in the head and neck region is made.
