Spindle cell hemangioma of the spleen: A case report

Spindle cell hemangioma of the lung: An unusual presentation

Spindle cell hemangioma (SCH) is a benign vascular tumour, first identified by Weiss and Enzinger in 1986. Habitually, the SCH affects almost exclusively the dermis and subcutaneous tissues of distal extremities. So far, only 2 cases have been described in the lung. We describe herein the third case of SCH occurring in the lung in a 47 year-old woman. The patient was successfully treated by right lower lobectomy. The histopathological and immunohistochemistry examination of the excised tumour leads to the definitive diagnosis. Our case is instructive by its different clinical and radiological presentation compared to the previous two cases.

Treatment with sorafenib plus camrelizumab after splenectomy for primary splenic angiosarcoma with liver metastasis: A case report and literature review

BACKGROUND

Primary splenic angiosarcoma (PSA) is an extremely rare and aggressive mesenchymal malignancy with high metastatic potential and a poor prognosis. There are no established treatment guidelines for PSA, even for adjuvant therapy. This rare case may provide a reliable therapeutic regime for a better prognosis.

CASE SUMMARY

A 49-year-old female who complained of right-upper quadrant abdominal pain was diagnosed as having PSA with splenic rupture and liver metastasis. After splenectomy and liver tumor resection, she received sorafenib and camrelizumab therapy. After 15 mo of follow-up, she is in good condition, without recurrence or any identified metastasis.

CONCLUSION

Immunotherapy combined with targeted therapy could be a potential option for the adjuvant therapy of PSA.

Spleen angiosarcoma: a world review

Introduction: Spleen angiosarcoma (SA) is a rare malignant neoplasm that arises from the splenic vascular endothelium, with only around 300 cases reported to date. Due to a limited number of reported cases, there is a paucity of data and a lack of understanding of its presentation, diagnosis, and management. In this study, we aim to provide a comprehensive review of SA.Areas covered: On 27 February 2021, a literature search was done in PubMed and Embase database. The search yielded 122 articles involving 205 patients. The focus was on patient demographics, risk factors, clinical presentations, investigation results, preliminary diagnoses, therapies provided, and patient outcomes. These factors were analyzed to identify possible risk factors, diagnostic modalities, and therapeutic principles that were not mentioned before.Expert opinion: The clinical presentation or investigation results of patients with SA are often nonspecific. Hence, they may not be sufficient to clinch the diagnosis of SA if used alone. The authors recommend a triple assessment of clinical examination, imaging findings, and pathology to diagnose SA with high accuracy. Splenectomy should be the mainstay of management, with chemotherapy and radiotherapy considered as adjuncts, especially in the presence of metastases.

Successful Outcome After Intralesional Curettage for Spindle Cell Hemangioma of Fibula in an Infant: A Case Report

Spindle cell hemangioma (SCH), a non-neoplastic reactive vascular lesion, rarely locates in bones. We herein report a successful case of intralesional curettage for an infant with SCH of fibula. An 11-month-old boy was admitted to our center with a painless mass in the right proximal calf. Preoperative digital radiograph demonstrated a massive vascular lesion with an irregular bone destruction of proximal fibula. The lesion was removed via the intralesional curettage approach and pathologically diagnosed as SCH. The patient gained bone structure recovery of right proximal fibula. Two years after the surgery, he experienced no local recurrence. For the management of SCH of fibula with partial bone destruction, we suggest early-stage intralesional curettage as its safety and effectiveness.

Characteristic appearance of spindle cell hemangiomatosis, often misdiagnosed as venous malformation: A retrospective study of 11 cases

Spindle cell hemangiomatosis is a benign multifocal vascular proliferation that mostly occurs in the distal extremities. It is a relatively rare disease and causes difficulties in clinical diagnosis and differential diagnosis of venous malformation. We retrospectively assessed the medical history, and clinical features, imaging features, pathological features and follow up of 11 patients diagnosed pathologically with spindle cell hemangiomatosis after surgery. There are two types of clinical appearances in spindle cell hemangiomatosis in the distal extremities: bleb-like nodules and varix-like nodules. Bleb-like nodules are mostly superficially located in the palm or interphalangeal joints with obvious hemorrhage in lesions and mainly composed of cavernous spaces rather than spindle cells. Varix-like nodules are located in the back of the hands or arms with normal skin color and mainly composed of solid areas of accumulated spindle cells. Surgery is the standard therapy for spindle cell hemangiomatosis, while sclerotherapy is invalid. Despite the tendency to develop new lesions, there are no residual lesions at the surgical site during follow up. Bleb-like nodules in the palm and interphalangeal joints are a typical clinical appearance in spindle cell hemangiomatosis which can help make clinical and a differential diagnosis of venous malformation. Surgery is the standard therapy for spindle cell hemangiomatosis with no residual lesions remaining at the surgical sites.
