Retroperitoneal spindle cell tumor: a case report

Spindle cell tumors exhibit a relatively low occurrence rate and can manifest in various locations within the human body, including soft tissues and bones. The process of making a diagnosis is supported by conducting pathological and immunohistochemical tests. A 50-year-old female patient visited the hospital with abdominal pain that lasted about a week. Magnetic resonance imaging of the pelvis showed that this mass was independent and was not a lymph node mass, but a retroperitoneal sarcoma type mass. As part of the treatment, the mass was surgically excised, and a supracervical hysterectomy was carried out. The tumor was wrapped in a grayish-white capsule and showed a lobulating pattern. Retroperitoneal spindle cell tumors, particularly those occurring in abdominal soft tissues, are infrequently observed. Histopathological diagnosis is done in stages, and when cases are ambiguous, immunohistochemistry can provide valuable guidance in the right direction.

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.

Tonsillar Epithelioid Haemangioendotelioma: Description of a Rare Clinical Case

We present a rare case of tonsillar EHE with local recurrence and neck metastasis 30 months after surgery, as well as further neck recurrence 27 months later. We describe clinical, immunohistopathological, and therapeutic aspects of the tumor highlighting the diagnostic difficulties, lack of therapeutic guidelines and need for long-term follow-up.

Retroperitoneal Spindle Cell Tumor: A Case Report

Spindle cell tumor is very rare. Herein, we report a case of retroperitoneal spindle cell tumor in a 52-year-old female. The patient first presented with a complaint of persistent pain in the right upper abdomen. In the follow-up, a CT scan was performed and showed a retroperitoneal soft tissue density mass measuring 11 cm in diameter. Then, a subsequent operation was performed, and we completely removed the tumor and partially invaded lesions. The tumor was histologically diagnosed as a spindle cell tumor. Therefore, it is imperative for us to enhance the understanding of this seldom found tumor. Surgery remains the best option for treatment.

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.

Spindle cell haemangioma of the tongue

BACKGROUND

Spindle cell hemangioma (SCH) is an uncommon benign vascular tumor that rarely occurs in the mouth.

METHODS AND RESULTS

We present an SCH arising in the tongue of a 52-year-old otherwise healthy woman. SCH should be considered in the differential diagnosis of vascular tumors in the oral cavity and not misinterpreted as a more aggressive vascular tumor. We describe the clinical presentation, investigation, differential diagnosis and management of this condition and a literature search showing published case reports.

CONCLUSION

Although SCH rarely presents in the oral cavity it needs to be considered in the differential diagnosis of oral cavity tumors.

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.

[Spindle-cell hemangioendothelioma of the pharynx managed by radiotherapy]

Spindle cells hemangioendotheloma generally reaches the extremities. Only one oropharyngeal localisation was described in the literature. We report the observation of a 41 years old patient who was operated twice for this localization. The patient presented in 2005 with a third recurrence with important local extension contraindicating surgical treatment. An external radiotherapy was carried out with a good local control of the lesion. In the light of this observation we will discuss physiopathology of this rare lesion and the various therapeutic options.
