Spindle cell haemangioendothelioma in an arteriovenous fistula of the ring finger after blunt trauma

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.

Expansile kaposiform hemangioendothelioma deformed thoracic cage in an adult

Kaposiform hemangioendothelioma is a vascular tumor that commonly presents as a cutaneous mass, is observed in children, and is associated with Kasabach-Merritt phenomenon. Herein we report a case of kaposiform hemangioendothelioma with chest wall deformity in an adult who did not show the Kasabach-Merritt phenomenon or cutaneous lesions. To our knowledge, this is the first case of asymptomatic kaposiform hemangioendothelioma arising from the pleura and deforming the chest wall. The patient was treated with tumor excision and chest wall reconstruction.

A case of angioleiomyoma presenting as a pulsatile tumor in the left ring finger

Angioleiomyomas in the finger are rare and their preoperative diagnosis is difficult. Most of them are not associated with arteries and their chief complaint does not reveal pulsation tumor. We report a case of the angioleiomyoma in the finger which was misdiagnosed as arteriovenous fistula of tumor, based on the presence of pulsating tumor and angiography finding.

Spindle cell hemangioendothelioma of the temporal muscle resected with zygomatic osteotomy: a case report of an unusual intramuscular lesion mimicking sarcoma

Spindle cell hemangioendothelioma (SCH) was originally described by Weiss and Enzinger (1986) as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities. Few reports describe SCH of the head and neck region; even fewer note intramuscular SCH. Here, we describe a case of SCH involving the temporal muscle mimicking soft tissue sarcoma, who had a successful surgical treatment with a coronal approach and zygomatic osteotomy.

[Vascular anomalies of the children's hand]

Vascular anomalies are common on the hand of children. There are two types of vascular anomalies: the vascular tumours and the vascular malformations. The most frequent vascular tumour is infantile haemangioma. The vascular malformations could be predominantly venous, lymphatic, capillary or arteriovenous. Combined vascular malformations, often syndromic, must be searched for. Diagnosis is sometimes difficult. It is based on clinical history, aspect, evolution and radiological examinations (color-Doppler ultrasound and MRI). Treatment is often a combination of medical and surgical approaches performed by a multidisciplinary team.

Spindle cell hemangioma (hemangioendothelioma) of the head and neck: case report of an unusual (or underdiagnosed) tumor

Spindle cell hemangioma (SCH), also known as spindle cell hemangioendothelioma, is a unique vascular tumor with combined microscopic features of both a cavernous hemangioma and Kaposi sarcoma. It almost exclusively affects the dermis and subcutis of the distal extremities. A review of the literature disclosed only 5 cases of SCH reported in detail in the soft tissues of the head and neck. An additional case of SCH manifesting as a submucosal nodule in the upper lip of a 29-year-old woman is presented. Because this is the second case reported from the same institution, it is suggested that SCH is an underdiagnosed lesion.

Multiple mucinous and lipomatous variant of eccrine angiomatous hamartoma associated with spindle cell hemangioma: a novel collision tumor?

Eccrine angiomatous hamartoma (EAH) is a rare, benign condition characterized histologically by increased numbers of eccrine elements, as well as numerous capillary channels. In most cases, EAH arises as a single lesion; however, multiple variants have been reported. We report a 35-year-old female patient with multiple, sudoriparous, subcutaneous nodules on the right foot, which showed typical histopathological findings of EAH, and vascular components of the tumor consisted of thin-walled dilated vascular spaces intermixed with spindle cells and some histiocytoid endothelial cells representing spindle cell hemangioma (SCH). To our knowledge, the co-existence of EAH with SCH is a novel finding and not yet described.

Vascular lesions of the hand

The vascular malformations are not uncommon on the hand and offer diagnostic and therapeutic challenges. Enjolras and Mulliken's classification is exposed. Their depiction and pretreatment assessment may benefit from non-invasive imaging as color-Doppler ultrasound and MRI combined with magnetic resonance angiography (MRA). Some chronic traumatic vascular injuries as the hypothenar hammer syndrome may also take advantage of these imaging modalities.
